i wonder if there is a problem with FakeSMC. verleihnix had problem a while back and went back to Rehabmans build RehabMan-FakeSMC-2013-0706.zip

 

here is rehabman's site https://code.google.com/p/os-x-fake-smc-kozlek/downloads/list

tuck-

I tried this version of FakeSMC but get the same problems, if I use a vanilla AppleACPIPlatform (v1.7 or v1.8) I get SMC errors...

So, I am back to the custom version.

Thanks,

AJ

@AJ - ErmaC has provided a patch to 10.8.5 v1.8 AppleACPIPlatform.kext 

           hit download button and get AppleACPIPlatform.12F45.zip

 

 

Note: I am writing this from Safari 7 on 10.9 GM - thanks Tetonne! - everything works great. 10.9 is should be a fairly easy upgrade. I was able to patch AppleHDA (including manwe150's input fix).

Here you could put AppleHDA.kext to 10.9 Mevericks ??

 

Thanks

Thanks tluck, will download and install it.

10.9! great. What process did you follow to install? Did  you upgrade your 10.8 or did a fresh install?

Using clover and the same kexts?

Hi,

I had a head crash a few days before, today the replacement HD arrived.  :)

I like to go for clover this time. Maveriks is already installed.

It sems to boot fine, but not into graphics.

Framebuffer messages is coming up: "SNB Framebuffer did not show up, unload"

dsmos arrives. HD led is still flashing in background. Has 1600x900 LCD

 

any suggestions

@verleihnix - do you have FakeSMC (and other kexts) installed  to HD  /S/L/E? there were some problems with kext injection until b2217 


 


I just reposted with Clover b2217 - this might make it easier for folks to make either a 10.8 or 10.9 USB installer as well sort out the OEM section.


The top level config.plist will inject the kexts which are good for an installer or so that a virgin installation will work. i


 


Note: currently i prefer to install custom kexts on my HD /S/L/E versus  just leave on clover ESP.

Hello tluck sorry if this is off topic ,  i'm using your patched applehda from 10.8.5 with the same dsdt edits as your laptop (mine is x220) and works great when i'm using unpatched acpiplatform 10.8.4 kext but when i'm using unpatched acpiplatform from 10.8.5 the sound works alright but after sleep/wake i lose the sound from the speakers but the headphones work! (that's weird) , the sound from the speakers comes back only if i shutdown the laptop and turn it on again, if i restart i still have no sound from speakers , ( if i use the patched files from ErmaC it works ok but i'm preparing my dsdt for Mavericks too and want to stay native :) ) , its weird that headphones works perfect always and only the speakers dont work

@sot_22 - i did a quick test on 10.9 with unmod ACPI kext and same thing?! laptop speaker is dead but lineout/headphones still work after wake? maybe we need ErmaC to patch one for 10.9 too! good to know that his patching seems to help us (as well as others). not quite sure what his patch is all about at this time.

thanks for confirming this problem, it seems apple changed something in acpi kext on 10.8.5 and onwards which broke first for them (now it seems fixed) HDMI audio after waking from sleep as stated by their supplemental update and second our speaker audio ... if ErmaC can patch the 10.9 will be great , i'm searching for a fix or the cause of disabled speakers but i didnt find any info yet

not to take anything away from ErmaC,  but I looked closer at his patched AppleACPIPlatform.kexts. Well it seems he is more or less just leveraging the Snowleopard v.1.3.5 binaries in his 10.8.x kexts. in other words it seems as if is the same as what we were using in earlier on when we replaced AppleACPIPlatform with 1.3.5. 

 

But I wonder why some can use the actual native AppleACPIPlatform from 10.8.5 and 10.9 and some can't. i am on Bios 1.46 with embedded controller v 1.20.

(for the ones having smc errors) remove the ACPISensors plugin from fakesmc and see if the errors go away or maybe wrong ssdt or dsdt, i read that some errors are normal (like SMC reverting to old mode etc...) i have them too and they dont do anything wrong

 

another one setting to blame is if they have virtualization vt-d enable in bios (it must be disable for osx to boot) but this info is on this thread already :)

Hi guys, I do get the errors... and I think I recently enabled the vt-d virtualization in the BIOS. I will check the computer tomorrow and try again. I think this could be the reason...

if ErmaC patch is basically a rollback to v.1.3.5 binaries (i don't know if thats the case) then its better to find a way for the speakers sound to work with the native kexts now that there isn't a problem with the battery anymore , this blog : https://digitaldj.net/blog/   if you scroll a little down the posts has some info on applehda , i don't know if this helps or can help if there is some detail in applehda which needs tweaking now cause if there is something wrong in acpiplatform kext and disables the speakers after sleep why it doesn't happen on real macs too

Hi guys, just confirming that I had the vt-d virtualization enabled in the BIOS, and that was causing the SMC errors with vanilla AppleACPIPlatform from 10.8.5.

I have disabled this option in the BIOS and now all runs good with the vanilla kext.

I think somebody else had this issues as well. If so, please check your vt-d virtualization.

 

Thanks a lot tluck and sot_22 for your help.

@ag695263 - great news. glad the new DSDT etc is working fine for you too.

 

@sot_22 - excellent article -  I added the Max Beep thing into the DSDT and no assertion now. don't think i will get into any detailed size patching as it works fine as is. 

the speaker thing seems to be broken with 1.8 ACPIPlatform (from 10.8.5) and later. The v1.7 from 10.8.0-10.8.4 works fine - even with 10.9. Although my esata disk does not alway wake from sleep with this older version; the later versions seem to do better job here.

Hey,

today I tried installing 10.8 on my T420 (4236-C32, HD+, i5, 2.5GHz) without WWAN and with SSD.

I tried all of the bundles from this thread, but non of them works for me.

With the clover bundle from the first post I was able to successfully boot into the installer and install OSX to my hard drive.

But whenit reboots it only shows "Installing" and a "progressless progressbar". (Dont know how it is called :D)

Waited for hours, but nothing happens.

 

Using other clover bundles I only got "waiting for AppleSMC".

 

Using the latest bundle from tluck I can boot too if I set InjectKexts to true, but it also hangs in the installer screen after rebooting.

 

Of course I tried different DSDTs/no DSDT, etc.

I have no idea what I can do.

Does anyone have another idea? :-)

 

Greetings,

Simon

 

Edit: BIOS settings are like mentioned on the first pages.

@vapayo -- i am not sure i understand what state you are in after you install. i use LionDisk maker to make a 10.8.5 installer and when done - you reboot.  then it there isn't any progress bar? how did you make the installer? the bundle i built is good for the installer and the HD after install.

Hey,

thanks for your answer.

I also created my usb stick using Lion Disk Maker using an Installer.dmg.

 

But I also have never seen such a result. I boot the usb stick, format my drive using the disk utility and after installing clover calls my hdd "OSX Installer".

When booting it looks like shown in this video:

 

Edit: I just redownloaded the installer app and reinstalled but nothing changed. :(

@vapayo - thats an odd thing to happen. the LionDisk Installer after boot up should put into a panel that asks what Language etc.  is this on a fresh HD? if not maybe you have some left over .IAbootfile folder in the root?

Hey,

thanks for your answer.

The language dialog comes when I boot the installer usb. (I select german, the setup is german, but when rebooting the "installing"-screen is english)

 

I have 3 Partitions on my harddrive, EFI, Windows, OS X.

Before installing I always formatted the OS X partition using the disk utility, so I think there shouldnt be some left files, right?

well. if OSX is installed on your HD, then Clover should NOT be giving you this option: Boot OS X Install from Machintosh HD. some how you have an installer option and not the "regular OS" ... for it should be give you option: Boot Mac OS X from Machintosh HD

Hmm,

is there something I can do about that?

 

I have not done anything special except the windows partition, but I do not see why this should make my fresh installation an installer. O.o

 

Edit: And it is 100% on the harddrive, I can boot it when I remove the installer usb stick.

      Script file to clone and help build Clover or Opencore repos
      Script will create link to itself in /usr/local/bin/bob
      Script SHOULD fix up any stray bobs you may have.
      Then you only need to type bob. and a parameter
      "a" for ACID repo, official
      "d" for ACID repo DUET build
      "c" for CLOVER
      "e" to erase UDK Folder
      Easier typing bob than.....usual stuff
      YOU WILL NEED TO cmod+x THE SCRIPT
      Enjoy

      Hi All,
       
      I'm trying to install Catalina via Clover, however, it hangs on ACPI errors. I've managed to reduce this from 6 to 4, but there's still some outstanding. 
       
      I'm thinking this may require DSDT patching to get by, but on the below information, how to do I gauge what I need to locate, and change values to?

      I've been lucky with past machines, rarely required a DSDT edit. The EC patch for Catalina has been applied.

      Model - Lenovo A540
      CPU - Intel® Core® i5-4258U (2.9 GHz)
      Chipset - Haswell
      Boot - UEFI Clover
      GPU - Intel Iris / HD Graphics 5100
      Resolution - 1920 x 1080
      Storage -  1TB hard drive
      RAM - 8GB

      Vector themes for Clover are new and currently still under development. Setting out to re-create my BGM theme to vector I realised there was some learning needed in order to create a theme.svg file for Clover to use. As SVG files are text based, I quickly realised that they could be manipulated from the command line and looking at the Clovy theme I decided to break it down in to parts for creating other themes.
       
      As a result, I've been working on Clover SVG Theme Builder
      https://bitbucket.org/blackosx/cloversvgthemebuilder
       
      Current Version:
      0.4.5
       
      Overview
      The idea is to allow a theme designer to work on individual images and not worry about the required overall file structure which Clover expects. The designer can populate a Theme directory with a settings file and individual .svg files and let the script generate a final theme.svg file for using with Clover.
       
      I've created a basic sample theme to help demonstrate the script.
      https://bitbucket.org/blackosx/cloversvgthemebuilder/downloads/Theme.zip
       
      The Theme directory contains Adobe Illustrator and SVG files for each image in the required folder structure for the script.
       
      Using this sample theme, the script will generate this theme from the files.
       

       
      The idea is these can be used to build new themes and I'm currently using it to build my BGM_SVG theme.
       
      I can imagine far more complicated themes will be generated in the future, but for now I hope this may serve to help kickstart basic vector theme development.
       
      Notes:
      • Clover's SVG theme development is still underway and things are likely to change so this script and it's supporting template file will need to change with Clover.
      • I've only tested this using SVG files saved from Adobe Illustrator using the following settings, for files from other apps may need added support.



      • For the script to correctly inject SVG code in to the template, each SVG image must contain a group of elements.
      • Font files are currently not included in the final theme file but this can be an option.
      • In time, maybe other templates can be added which have different layouts??
       
      These are early days, so I'll update this post when necessary.

      Bonjour,
       
      Depuis Catalina, l'extention Applebacklightfixup ne fonctionne plus. J'ai trouvé une solution en le supprimant de EFI/CLOVER/KEXT/OTHER/ et en gardant SSDT-PNFL.aml dans EFI/CLOVER/ACPI/Patched.
       
      j'ai pourtant plusieurs soucis :
      - le réglage de luminosité de l'écran ne reste pas toujours en mémoire d'une session à l'autre après un shutdown ou un restart (c'est aléatoire)
      - Le curseur de luminosité du panneau de conf affichage, lorsqu'il est positionné complètement à gauche met la luminosité de mon écran à zéro, donc tout noir... et c'est embêtant si je relache ma souris dans cette position !
      - Dans le paramétrage "clavier" du panneau de conf, onglet raccourcis, je n'ai pas d'item "affichage" pour afffecter le réglage de luminosité à F11 et F12 (ou à F2 et F3 sur mon toshiba satellite).
       
      J'ai essayé de mettre une valeur dans config.plist dans system parameters/backlight level. j'ai saisi 100, il m'a affiché 0x100, mais au redémarrage, mon écran restait noir. J'ai donc effacé cette valeur. Comment fonctionne ce paramétre et quelle valeur faut-il y indiquer ? Existe-il une solution plus propre sur Catalina 10.15.5 pour résoudre ces problèmes (j'utilise le CPU intel de mon toshiba satellite L50B - 1N2, pas le GPU radeon).
