thanks Tetonne.

i'l move to OEM folder as suggested.

i'll report with icloud and imessage later on.

thank tluck.

i'll try you suggestion and back with report.

hi Tetonne,

 i am able to sign in to icloud, and syncron my address book and others.

 but still no luck with my imessage. :( able to log with my password to my imessage, but after a while, it said registration failed.

 

hit tluck,

 tried your kext but failed. tried to patch on my own, and failed miserably :))

 so i'm gonna stick with VoodooHDA version 2.8.4. it works on my internal speaker and headphone.

 it's just that i need to manually change the output to headphone in sound's preference pane when i plug its jack.

 for the battery, you're right. i need to patch my DSDT. fortunately, rehabman provide the patch and comment on patched DSDT.

 on my case, it's related to 16 bit memory that need to be converted to 8 bit in DSDT declaration. (sort of... :D)

 i got the battery patch from this link.

 hope helps anyone out there having problem same with mine. :)

 

i'll update my clover package on my previous post.

 

next will be activating my displayport or VGA on the left side. :D

@tluck and @Tettone,

regarding usage of displayport, i've tried to use dsdt as followed:

 

Method (_DSM, 4, NotSerialized)
                {
                    Store (Package (0x02)
                        {
                            "AAPL,ig-platform-id",
                            Buffer (0x04)
                            {
                                0x03, 0x00, 0x66, 0x01
                            }
                        }, Local0)
                    DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
                    Return (Local0)
                }

i can get my LCD and external monitor connected to display port works. but my LCD got stretched, only half of screen is shown while the external monitor works perfectly.

i also get memory for graphics increase to 512MB instead of 384MB.

any idea to solve this issue?

 

interesting part for me:

- when in DSDT i set: "0x04, 0x00, 0x66, 0x01 " and in config.plist i set 0x01620003 in ig-platform-id, looks like the DSDT setting is the one used.

------------update-------------

i finally able to use my mini display port by editing the AppleIntelFramebufferCapri in AppleIntelFramebufferCapri.kext\Contents\MacOS.
for reading material, u can go to this discussion: http://iatkos.me/forum/viewtopic.php?f=77&t=23300
 

on my T430, it's known that the lid/internal LCD display works with ig-platform-id: 01660004.
so, i keep using ig-platform-id: 01660009 (able to see 3 ports, LVDS, and 2 displayport) and edit the LVDS part to have same value as LVDS part in ig-platform-id: 01660004.

the use ig-platform-id: 01660009 gives me 512Mb graphics memory. that's higher than using ig-platform-id: 01660004, which only gives me 384MB memory.

one thing to note:

the poster wrote in his post that,

 

AAPL,ig-platform-id: 01660004, Stolen RAM for FB: 32MB, Pipes: 3, Ports: 1, FBMem: 1
@0, 05 03 00 00 02 00 00 00 03 02 00 00 // LVDS

however, in my installation, the 03 (bold) is shown as 30.

so i use 30 when editing.

after editing the kext, i reinstall the kext to SLE using kext wizard, update the kext cache, then reboot.

voila.... got my internal LCD display and my DELL monitor works together.

tried the VGA, but no luck.

not a big deal, i rarely or even never use the vga so far.

 

hope it will helps someone someday. :)
 

thx.

most of us on this thread (having a T420) have Intel HD 3000 graphics. so we dont need to inject the  platform id for gfx. for your box which has HD 4000 is a bit different. i have seen some posts regarding this aspect. 

 

as far as LCD display stretching, you may need explicity add DualLink=1 for your LCD - can be added explicitly in the dsdt and/or clover's config.plist

 

 

                            "AAPL00,DualLink",
                            Buffer (0x04)
                            {
                                0x01, 0x00, 0x00, 0x00
                            },
 

 

also it seems your T430 has ALC269 based on the realtek audio chip? vs conexant - that explains why the AppleHDA.kext i posted does not work for you. Kogen - the original creator of this thread moved from a T420 to T430 - maybe he has a new thread or info on T430 specifics?

 

thanks for sharing your results - if you do get a dsdt working with AppleSmartBattery kext - please share that ... i would be interesting in retrofitting for the T420 crowd.

 

good luk

Hey!

I was wondering whether or not do you people with a T420 get any issues with shutdown (instead of shutting down the laptop just freezes with screen off randomly) when using pure UEFI Clover (I assume with EmuVariable, AptioFix and FatBinary drivers)?  I'm asking because I have a laptop with Phoenix SecureCore Tiano (UEFI 2.0) of the same era (Sandy Bridge/HM67) and me and some other people get the shutdown freeze on our laptops, not necessarily Dells, but Lenovo and Asus as well. I would like to hear what kind of setup are you guys running in case you don't have such an issue. I hear it's only under mountain lion and doesn't happen on Lion, but I'm not really keen on reinstalling the OS just to check this and possibly be really disappointed. In any case a private DarwinDump made with a software of later version (to cover sensitive data such as serial numbers) would be really appreciated.

 

Thank you in advance.

well i dont get a freeze issue with shutdown. sometimes if i when issuing a shutdown via Mac Shut Down, it will shutdown the OS (grey screen etc with rotating circle). but then sometimes it just stops at a black screen and does not power off the bios/uefi.   so then i have to hold down the power button for 5 seconds to get a total power down. yes using EmuVariable AptioFix and FatBinary drivers.  i am running ML 10.8.4.  i dont shutdown all that often so its not been a huge problem.

 

any ideas or progress on this would be greatly appreciated. thanks for reaching out!

That is what I was referring to as well.. so it's a common issue for Tiano which to be solved requires certain feedback. I'm struggling with this since clover revision 974, ever since UEFI boot was made possible based on the debugging dmazar did on my Dell and some other guy's Lenovo x220. At first I blamed EmuVariable to cause this, then I came to think it's a bug in the firmware.. but now people with AMI Aptio UEFI seem to have it. So I have no idea what to blame.

@TimeWalker75a - yeah this not shutting completely down is a hard one to figure out. i tried a few things (e.gturned off extended UEFI memory) and nothing seems to change. over the last 2 days i have been shutting down at random times. shutdown is about 50% for me  - meaning i let runtime varies from 5 minutes to 14 hours and then attempt shutdown. sometimes it shuts all the way down as expected. But sometimes the OS shuts off and system it will remain "hung-zombie-on" - blackscreen with the bluetooth light on etc.

E330 User here :)
I keep getting stuck on 

"root device uuid is"

regardless of which boot option I choose (cache/kexts) and regardless of whether I enable or disable Duallink in the config.

Perhaps my install media is corrupted somehow, because everything went through without throwing an error message, but in the end I need to force eject the usb install medium (used it for osx and your pack), because EFI wouldn't unmount.

 

any ideas? cheers!

@weishauptus - i take this is after you install the OS? did you install some of the core kexts? or are you injecting them? does it show the UUID of the boot disk? what clover drivers are loaded? need FSInject, OsxFatBinary OsxAptioFix, Emuvar, VboxHFS,

Re: shutdown issues on SC Tiano.

Hopefully @apianti will have time to look into UEFI debuggin protocol, but there's no possible way to debug the afterlife phase, so not sure how helpful this could be in terms of solving the shutdown hang. Though, it can possibly lead to debugging the startup phase in hopes to get rid of emuvariable in case the reason for cpudeadloop is found. At the moment it looks like the bug's inside the firmware which is produced by Phoenix for this (SNB) generation of laptops and hence there's no way to fixing it ourselves..

Hi tluck, thanks for the reply.

Nope, unfortunately this is even before reaching the installer, sorry for being unclear on that one. It does show the UUID of the boot disk however. After that line it just freezes and becomes unresponsive. The E330 is a i3 machine using the intel HD4000 internal graphics, if that is of relevance. Perhaps the DSDT is getting things stuck?

@weishautpus.

 

- hmm. if you get Loading Drivers...  dot dot dot then it is trying to load the kexts and then getting hung?. if not then it is not even getting that far.

 

i think based on your description, your installer is clover based? you may want to try to make a USB installer with Lion Disk maker? or some other method besides clover.

hi tluck,

 as per your request, i confirm that the latest version of AppleSmartBattery.kext  by rehabman is working on my T430.

 He fixed the fully charged battery to be shown as 100%, previously it was shown as 86%.

 i put my clover folder in post  #318 on this thread. http://www.insanelymac.com/forum/topic/285678-lenovo-thinkpad-t420-with-uefi-only/page-16?do=findComment&comment=1935831

 you can find my dsdt there.

 the AppleSmartBattery.kext in that folder is still in version 1.32, you can download the latest version (1.33) source from rehabman's github.

 https://github.com/RehabMan/OS-X-ACPI-Battery-Driver

 the build version download link also available on that page.

 

thanks.

@gendalo76...

 

thanks! very cool. rehabman's stuff is great. i was hesitant as I seem to recall some early posts around using AppleSmartBatteryManager and they all seemed to require a lot of DSDT changes/edits. But I am able to run rehabman's AppleSmartBatteryManager v1.33 without any dsdt changes.

 

in /S/L/E

  1. removed VoodooBattery.kext
  2. removed stock AppleSmartBatteryManager.kext
  3. installed new AppleSmartBatteryManager.kext
  4. edited the Contents/Info.plist - changed key UseExtendedBatteryInformationMethod to false (for v3 ACPI )
  5. reboot

 

seems like i get 4% more out the battery because it started out at 96%! it is working just fine - shows 100% now.

 

So now I am using rehabman's set:

 

  • FakeSMC + sensors app (just installed CPU and ACPI plugins)
  • VoodooPS2controller 
  • SmartBatteryManager

Hi all,

     First of all thanks for @tluck's EFI package and everyone else on this thread ----I got a T420 4180RW2, which has i7-2620M, HD3000 with a device id 0x0126 & NVS4200m with the device id 0x1057 (I turned of Optimus and use the internal graphics chip), QM67 and 1600x900 resolution.

     I used @tluck's Clover package ( b1942 ) to install 10.8.3 onto my T420.  The system has recognized my HD3000 chip with its correct device ID and the resolution works fine, the kexts seemed loaded, but I got no qe/ci what-so-ever. I could not find the reason and would appreciate any help.

     btw, the nvs4200m's situation is similar: kext loaded and device id recognized, but no qe/ci.

     

    Option tested ----

      SMBIOS-MBP8,3 & 8,1

      graphicEnabler=yes or no

      load video bios = yes or no

      dsdt ---- my own without patch and tluck's version, placed in OEM folder.

I am trying to build a Hackintosh (first laptop one) and the T420 with 1600x900 was a natural choice.

 

I have installed a Atheros Wifi replacing the existing Lenovo one, updated to the 1.45 BIOS Whitelist (Google 1.45 Whitelist and BIOS Mods will give the result).

 

Laptop works great in Windows, but I am having two issues:

1. My starting point is iAtkos Ml3u on a USB stick - I set the BIOS up to boot (boots ok on desktop with UEFI) but it simply won't boot the UEFI

2. Using ML2 (non UEFI) I get a long way thru it - except I get to the 1600x900 being stretched and only half of it visible (actually looks like 1024 of 1600). Other than that, Airport works great etc etc.

 

I have looked at the this forum plus the GUIDE on the T420 but the BIOS revsion is not something anyone seems to be mentioning.

 

If I have a wrong BIOS Version, happy to roll it back. At one stage I got it working perfectly at 1024x768 - again all under ML2.

 

Any assistance gratefully accepted.

resolution is surely linked to dual link

(should be 1 in your case (read previous post about it)

you'll find tluck great dsdt and stuff at post post 241

 

in config.plist (graphic)

dualilink must be like that (for 1600 px)

 

<key>DualLink</key>

<string>1</string>

Ok... I think there is a gap in what I am trying to achieve.

 

I cannot use UEFI - I am looking for some guidance on getting ML3U which is a UEFI based version of 10.8. I have used DiskUtility to try and make a CLOVER boot, but this also doesn't boot on the machine I am trying to install on - I know I have the BIOS settings right - UEFI Only. CLOVER will not show any options - the cursor sits in the top left of the screen, as it also does with ML3U.

 

In the absence of NOT being able to boot via UEFI, I am booting using non-UEFI based ML2 - I am typing on it right now, and I have verified that the Driver for the 3000 is installed - its just stretched and only partially visible. This appears to be to do with the 1600x900x60Hz it is wrong on the AUO based LCD - this appears to be solvable via a DSDT.aml - I created one of these via DSDT Editor for Windows generating the file. The video driver appears to have QE/CI enabled, even though it is stretched as the main bar is transparent.

 

Sorry for being so descriptive - I'm trying to give everyone a complete picture - I am approaching things on two different fronts but UEFI seems to be a failure for me.

 

I have reverted to 1.43 whitelist as mentioned by some and still the same result.

@FredFrog

 

let my try to understand your situation and perhaps provide some information.

 

Clover, essentially being a bootloader,  offers 2 methods of start up - theses method are MBR vs UEFI GPT/GUID. if you dont see the Clover GUI then you must not have not installed it properly based on your media format. 

 

The T420 can boot from bios using MBR or UEFI - it depending on the format partition of the device selected. If your start device (disk or USB stick) is MBR formatted, it will look for boot0 in the MBR. 

 

BIOS MBR -> boot0 -> boot1 -> boot ->CloverX64.efi

 

if the disk is GUID/GPT formatted it will look in the ESP partition for /EFI/boot/bootx64.efi (bootx64 is the exact same Cloverx64.efi)

 

BIOS UEFI ->CloverX64.efi

 

so either way you would end up at the same point when using Clover. if you have just a blinking cursor, then clover was not installed properly. you can test this out by installing clover on a USB and then boot it up from the USB. (hit space to halt the count-down)

 

1) format a USB stick as MBR type with HFS partition. then install clover for NON UEFI type (uncheck the first 2 items and in 3rd item  Bootloader use install boot0af - and select a theme.

 

2) format a USB stick as GUID/GPT with HFS partition. then install clover for UEFI - select Install for UEFI mobo. and select a them.

 

So you can boot (start the boot loader) using either method - if properly installed on the media.

This is not a bios version problem. i have used Clover and/or Chameleon with bios 1.43, 1.44 and now 1.45. 

 

AFAIK, itATKOS bundled OSX with some custom kexts and installation tools. ML2 seems to be a repackaging of chameleon boot loader + OSX. where as ML3 is now based on Clover bootloader + OSX. i personally have not used the itatkos stuff as i prefer to use the standard apple version directly. anyway it seems like you were able to install OSX (using the ML2 - MBR/chameleon boot loader).  

 

as Tetonne mentions, the screen size thing is about setting DualLink to 1. clover can do this in the config.plist. but since you may not be using clover, then you must set this in the DSDT. I presume your OSX disk is MBR formatted and has/uses /Extra for Extensions and DSDT.aml). i posted 2 versions of the T420 DSDT in the clover bundle in this thread. one for low-res (no dual link set) and one for high-res (duallink=1). the clover bundle also has a number of custom kexts that will replace or add to make it work. 

 

good luck with your T420 hack. it seems you got it off the ground. 

 

many T420 users now use Clover on GUID disks with UEFI - obviously that is what this thread is about. FYI... there is another T420 thread  that is about Chameleon (MBR) if you plan to stay with that method.

tluck,

 

thanks for the info.

 

Ok, I have used the BootDiskUtility from InsanelyMac to create the Clover Install - I have verified it works on my Desktop as a UEFI install on the USB. I even used the Clover b1942 and replaced the whole EFI directory which then shows the ThinkPad Theme - therefore I know it works (old Linux developer, so have played with GRUB / Lilo etc since Slackware 0.95, so pretty familiar with boot loaders). The desktop is a Gigabyte Z68M-D2H with i7-2600 and 16Gb RAM - this machine runs ML3U from the same USB stick I installed the ML3U on previously - therefore, I know it works, both booting and installing OSX 10.8.3.

 

The T420 BIOS settings seem to be correct - as mentioned previously, I have flashed the bios with whitelist and installed the Atheros Wireless, both 1.43 and 1.45. I have tried all three USB ports for booting and still no result. The T420 is a 4236J73 - don't think this variation is anything different from the T420's I have been seeing around.

 

I would love to boot and install this using UEFI, which is why I posted here - I have a Plextor SSD installed to make it run fast once installed - and ML2 runs quick but alias not ML3U.

 

I can capture BIOS settings etc, but the cursor in the top left even using just BootDiskUtility - taking OSX install out of the equation seems to be the key - I should see Clover... but I don't.

 

Thanks for your help

Hi pvhien,

 

Could you upload your EFI folder and the kexts here?

@fredfrog

 so where are you at now with Clover UEFI and the T420?

 

bios settings. most are default. make sure turn on ACHI for sata and turn off VT-d (virtualization)

 

1) can you boot up a test GPT USB with clover using the basic install? i.e. see the Clover GUI?

 

2) do you have GPT disk with ML on it?

 

since you already have ML installed. if its not on a GPT format disk, can you copy from a MBR to GPT disk and then you should be good to go.

my advice is to get it working on regular disk and then migrate to SDD - which may require some trim support.

 

@pvhien - you could take a here             #241             for EFI and kext bundle.

tluck et al,

 

no, that is the problem - can someone verify that BootDiskUtility on InsanelyMac can make a bootable UEFI under Windows which the T420 can then boot successfully - that is what I am trying to get working - forget ML3U as it noise at present.

 

If someone can verify that in its simplist form that BootDiskUtility can make a USB drive that will boot on the T420, then I need to see why it won't on my machine. I have done exactly the setup that tluck specified - ie Security->Virtualisation->vt-d disabled, UEFI Boot Only, ACHI for SATA.

 

As stated previously, a BootDiskUtility created USB key for my desktop boots as UEFI, just not on the T420 - with Whilelist BIOS 1.43 or 1.45. I have also tried other logical things like different brands of USB Key.

 

I have tried taking the Hard disk out - ie booting UEFI from USB created with BootDiskUtility with no hard drive (SSD or spindle) and still same result.

 

At a loss...

1) on your mac desktop box reformat a USB with 1 partition hfs - in options - set to GPT mode.

2) use clover package installer - select the USB - check first 2 items UEFI mobo and ESP install and themes.

      Dear all,
       
      I have a external harddisk about 500GB, I installed the clover into it and the harddisk is GPT format, below is the 3 partitions details:
      FS01: EFI - disk0s1 - fat32
      FS02: install mac  image - disk0s2 -  hfs+
      FS03: install windows 10 - disk0s3 - fat32
       
      I can use this external harddisk to install Mac without issue, I use below steps to install windows 10
      enter the FS03:
      cd to efi/boot/ and excuete bootx64.efi
      after pop up the windows install screen, i click next and it shows error 'A media driver your computer needs is missing...' and the installation can not go any further.
      Firstly I use ultraiso to write the windows 10 image to a flash disk and no issue to start install window 10 so the image is working fine. Since I dont know how to write
      a wiindow installation image into harddisk partition, I used winrar extra all the files into disk0s3, am I missing some steps or actually clover not support to install windows
      by partitions, apprecating any helps.

      Not working:
      - Original Wi-Fi (Qualcomm Atheros QCNFA344A):  unsupported, you need switch to BCM94352Z or just use a mini usb wifi dongle.
      - NVIDIA GeForce GTX 950M: Optimus not supported.
      - Card Reader: Unsupported -> Can't really fix because I don't have any SD Card at the moment, maybe can be fixed by adding Prod & Ven IDs to AppleStorageDevices.kext, I never used it anyway. name: "USB2.0-CRW" Prod ID: "0x0129" Ven ID: "0x0bda  (Realtek Semiconductor Corp.)"
      For Wi-Fi:
      - 1st method: You can choose an external USB wifi dongle (I used TP-Link Archer T1U (5GHz support), TP-Link has official macOS drivers, you just need to install it
      - 2nd and I think the best method: Replace your M.2 Qualcomm Card with a compatible BCM94352Z card (you will have hand-off Bluetooth too), just install the kexts (enabled with BrcmFirmwareRepo.kext, BrcmPatchRAM2.kext, FakePCIID.kext, FakePCIID_Broadcom_WiFi.kext, they're all in my attached zip). You could buy this card from ebay, aliexpress, or amazon
       
      Issues:
      - None
      BIOS Settings:
      - BIOS version 1.15 (irrelevant)
      - Secure Boot: Disabled
      - Touchpad: Advanced
      - Boot mode: UEFI
      Getting ready for Installation:
      - Download the Catalina install zip (bootpack & postinstall): acer_aspire_V591G-55TU_cata.zip
      Installation:
      - Create an installer with any method you know (- Mac: createinstallmedia - Windows: Transmac, Vmware, Win32diskimager)
      - Copy my Clover folder to the USB's EFI folder
      - Boot with the Installer USB
      - If you stuck in boot, reboot and in the Clover bootloader select "config_debug.cfg" -> you'll have more informations about the freeze
       
      Please open the README.rtf in my install zip for more informations about the USB Installer & Post installation!
      On Catalina the System folder is read-only, so you need to remount in rw to modify System/Library. 
      If you have a single RAM and getting panic at boot, then you need to edit the "config.plist" with these (SMBIOS->after "Version 1.0"):
      ->Edit "Frequency" and "Size" to match your RAM values
      <key>Version</key> <string>1.0</string> <key>Memory</key> <dict> <key>Channels</key> <integer>1</integer> <key>SlotCount</key> <integer>1</integer> <key>Modules</key> <array> <dict> <key>Slot</key> <integer>0</integer> <key>Size</key> <integer>8192</integer> <key>Frequency</key> <integer>2133</integer> <key>Type</key> <string>DDR4</string> </dict> </array> </dict> </dict>  
      PowerManagement  fix:
      Set HWPEnable=YES in Clover (already set), CPUFloor to "700", Frequency to "2300" and "3200"(Normal and Turbo, if you have i7-6700HQ version then it should be "2600", "3500") and "FrequencyVectors" from "0x0d000000" to "0x07000000" in "S/L/E/IOPlatformPluginFamily.kext/Contents/PlugIns/X86PlatformPlugin.kext/Contents/Resources/Mac-A5C67F76ED83108C.plist", MSR _xcpm_idle Patch to KernelToPatch in Clover (If you have High Sierra, change "MatchOS" to 10.13):

      <key>KernelToPatch</key> <array> <dict> <key>Comment</key> <string>MSR 0xE2 _xcpm_idle instant reboot(c) Pike R. Alpha</string> <key>Disabled</key> <false/> <key>Find</key> <data> ILniAAAADzA= </data> <key>MatchOS</key> <string>10.14</string> <key>Replace</key> <data> ILniAAAAkJA= </data> </dict> </array> Reboot, and it's 800MHz in idle state, same on Windows.
       

      Elan SmartTouchpad
      I only use scrolling, one-, double- & tripletap
      If you want to try other gestures go to this link for more informations, options (v4.6.5) ->  DETAILS ABOUT THE SMART TOUCHPAD DRIVER FEATURES
      Fn Brightness keys not working with this, tried several things without success. With VoodoPS2Controller it's working, but you'll have no gestures (neither scrolling).
       
       
      Before updating to a new version of Catalina please update kexts (and clover if necessary) to newer versions to avoid kernel panics.
      Generate a serial number with Clover Configurator.app (open up your config.plist with CC then -> SMBIOS -> Serial Number -> Generate New)
       
      Catalina & Windows 10 Dual-Boot:
      Dual-boot clean install (on one drive), UEFI Only:
       
       Boot into your Mac installer, Create 2 partitions in GUID table (1 for Win (I used FAT32 but I think it doesn't matter what you choose), 1 for Mac),   Install Mac, boot with your USB, mount your EFI partition (use terminal or an EFI mounter app), create an EFI folder (if there is no folder), copy the CLOVER folder I attached to the EFI folder, restart,  Boot into your Win installer, Format the partition you created for Win, install.   Now, it's automatically booting into Windows. To use Clover open cmd in administrator, type:  bcdedit /set {bootmgr} path \EFI\CLOVER\CLOVERX64.efi       5.  You're done! It will booting into Clover when you start the system, and you can select Win or Mac (or another OS if installed on a 3rd partition).
       
      Dual-boot with Windows installed first (on one drive), UEFI Only:
      If you already have Windows and you don't want to lose all your data there is a hope:
      I created a video from this restore method: [Hackintosh] Dual-Boot High Sierra & Windows - when Windows already installed - no data waste - UEFI
      You need bootable Mac Installer and a full system restore image (link is in my video's description).
      (You may see errors if your EFI partition is not 200 MB)
       Boot into your Windows, resize your partition or create one for Mac.  Boot into your Mac installer and in Disk Utility format the partition you created.  Restore from image: select your full system restore image.  When it's finished restoring you just need to restart, then boot to the system with your usb.  When you successfully booted to Mac desktop, mount your EFI partition (use terminal or an EFI mounter app), open EFI, you will see there is a Microsoft folder already (don't touch that!). Copy my CLOVER folder to the EFI folder then Restart.  Now, it's automatically booting into Windows. To use Clover open cmd in administrator, type:  bcdedit /set {bootmgr} path \EFI\CLOVER\CLOVERX64.efi       7.  You're done! You can select your old Windows and your new macOS!
      (Only tried with Windows 8/8.1/10. I don't know Windows 7,etc.)
       
      IF YOU GETTING ERRORS DURING MAC RESTORE:
      - Make sure you have partitions in GPT
      - Windows using 100 MB EFI and will annoy the Mac restore. Don't worry, just ignore the errors.
       
      IF YOU GETTING ERRORS DURING WINDOWS INSTALLATION (could not be formatted, etc):
      - Make sure you have GPT partitions, and GPT (UEFI) installer, also disconnect all external storage drives (except the installer USB)
       
      IF YOU USED RESTORE METHOD THEN CAN'T MOUNT YOUR EFI PARTITION (No EFI partition found):
      - It's because your EFI is not 200 MB or not an "Apple" original EFI,  but do not worry, try another EFI mounter, or mount from terminal (I used EFI mounter v3: Getting errors, but you can mount and use without problem)
      - You also could "mount" the EFI from Windows:
      1st method: open cmd in administrator mode and type:
      diskpart list vol (Now select the "System" volume,(FAT 32) For example I select 4) sel vol 4 list part (Select System type partition, for example 2) sel part 2 assign letter=b (This will "mount" your EFI partition) Open Explorer++ or TotalCommander in administrator mode to manage EFI remove letter=b (This will "unmount" your EFI) 2nd method: open cmd in administrator mode and type:
      mountvol b: /s (This will mount your EFI) Open Explorer++ or TotalCommander in administrator mode to manage EFI mountvol b: /d (This will unmount your EFI) Thanks to all OSXLatitude members for helping me out! (Jake Lo, Hervé, Bronxteck, black.dragon74)!

      I just made a clean install of High Sierra on a 1TB crucial ssd. Installed clover Clover_v2.5k_r5070 into the EFI of this ssd, but when I tried to make it my default boot drive, the clover screen wouldn't come up, and left a black screen.
      I tried using the Olarilia usb drive and clover did the same thing.  The only way I can currently boot is to use my old drive with clover v2.4k_4945 then select  my new drive from the clover menu.   
       
      Do I need to install v2.4k on my new drive or is there a way I can get v2.5k working?
       
      I have a GA-x79-ud5 motherboard, AMD  rx580 graphics card and use a Sony 4k tv as my monitor.

      Clover r5101 ISO compiled with GCC and minimal config.plist compatible for use in VMWare Workstation.
       
      Tested with unlocked Workstation 15 running OSX 10.9 -->10.15 guest in Windows X64 host.
       
      Installation
      1. Download and unzip "EFI_Clover_r5101 for VMware.zip". Mount Clover-v2.5k-5101-X64.iso by double clicking on it.
      2. Mount your VM's EFI System Partition eg in terminal
      sudo diskutil mount disk0s1   3. Copy EFI folder from step 1 into the EFI partition
      4. Shutdown the VM, add bios.bootDelay = "3000" to your VM's vmx file
      5. Reboot your VM, press <F2> to access the VMware Boot Manager and add CLOVERX64.efi to the boot menu.
       
      Substitute your own unique and valid MLB and ROM variables in the /EFI/CLOVER/config.plist (Rt Variables section) to activate iMessage/Facetime on your VM.
