    Lenovo ThinkPad T420 with UEFI Only

    tluck, no problem - I will apply the kext from your 29 August compilation. I noted on page 15 that there was issues related to sleep and it appears to be still under investigation from others. I will also apply the PS2 Kext, as I am only doing it one at a time. Sorry for being vague - the machine is my 14yo's and he doesn't live with me, so I only get to work on it when he's over, which is only a couple of times a week. Regards

    Lenovo ThinkPad T420 with UEFI Only

    tluck Just reporting back. I mounted the EFI partition and renamed the 4236AT9 you supplied to 4236J73 and applied the AppleACIPlatform.kext. These two things had a remarkable effect on the graphics glitches (gone - was glitching and sometimes freezing on receipt of a Skype message, which caused the animation in the Dock) and I was able to do a 'quick' sleep. Ie, I tried it, it woke back up. However, a 'long' sleep - one where I left it for a couple of hours required me to restart completely by holding power for 4 seconds - the power button and sleeping moon LED was still flashing, but it didn't wake - same symptoms. I will now install the revised Rehabman's battery to get the battery power showing correctly - but almost a perfect MacBook. Thanks everyone who has contributed to this forum.

    tluck - the machine is a 4236J73 which has the 2520M, 1600x900 and I am looking at your instructions for Post 241 and just want to verify that I can rename the EFI\CLOVER\OEM\4236A79 to EFI\CLOVER\OEM\4236J73 and just use your supplied dsdt.aml from in there, then apply the AppleACIPlatform.kext. Sorry for being nervous at this point - but its so close that I don't want to break it :-)

    tluck et al, okay, we are up and running -using ml3u and the stuff you provided. Here's what I did: 1. Used tluck's instructions to create Clover UEFI boot USB on 8Gb Key 2. Created second USB key with ML3U as per their instructions 3. Put both USB keys in the T420 - the order was important as one USB is the boot (back one in my case), the ML3U was in RHS 4. On boot for UEFI only it will start the 8Gb USB CLOVER UEFI in 1 above, but it sees the ML3U - so I select that an install using reasonable customized options 5. Bootloader did not install via ML3U, but used tlucks instructions for creating USB key to make the Plextor SSD bootable ie by downloading and installing CLOVER with the same options, this time installing to the SSD. 6. Booted and installed the entire EFI into the /Volumes/efi/EFI directory supplied by tluck - this fixed the screen resolution :-) 7. Updated via Software Update to 10.8.4 8. Installed the KEXT from tlucks for the audio and video - the video showed some artifacts - tlucks version fixed it. Sleep not working yet, but basically, a very good T420 Hackintosh. Will do some incremental tests on Tuesday to get sleep running. Thanks tluck and everyone in the community.... very impressive, if a little harder than my desktop version. Patience is a virtue - but support to the questions and a few educated guesses meant it works! FredFrog

    Lenovo ThinkPad T420 with UEFI Only

    Hi tluck, just reporting back. So I used Disk Utility on my sons true MacBook Pro with the 1Gb USB Stick, set the partition up with GPT and MacOS Journaled, let that do its thing. I then used Clover install r1974 from SourceForge and selected the source as the 1Gb USB, clicked Customise and selected the options - Clover install package failed to create it. I repeated the above steps, this time creating an MSDOS-Fat as well as MacOS journaled and tried again - still no joy. I was under the impression that there was an EFI partition created as well as the MacOS Journaled ? Am I doing this wrong or is it the r1974 version of Clover that is the issue ? Thx

    Thanks tluck - if that is how you were doing it, I will try that today and report back. Thanks for your help.

    Lenovo ThinkPad T420 with UEFI Only

    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...

    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

    Lenovo ThinkPad T420 with UEFI Only

    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.

    Lenovo ThinkPad T420 with UEFI Only

    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.
