tluck Posted October 11, 2018 Share Posted October 11, 2018 @Dabman1988 - not sure whats up with your issue. I just posted a newer zip with latest Clover and kext updates. Could be a fix for your situation? otherwise the older releases still work for High Sierra right?

jenyunhuang Posted October 11, 2018 Share Posted October 11, 2018 (edited) @tluck - I have one problem with using the newer zip(20180929 or 20181011). The battery cannot show on screen bar and the battery capacity is 0. How can I fix it?

tluck Posted October 12, 2018 Share Posted October 12, 2018 @jenyunhuang I do not know exactly what is going on ... but maybe the battery manager kext is not loading? i have not tested the latest packs on Sierra. But in your case, maybe you should just stay with the older kexts from previous releases? 1 Link to comment https://www.insanelymac.com/forum/topic/285678-lenovo-thinkpad-t420-with-uefi-only/page/176/#findComment-2640293 Share on other sites More sharing options...

tluck Posted October 15, 2018 Share Posted October 15, 2018 (edited) Sorry - Somehow i lost that item in config.mojave.plist from the latest release. i will add it back for a 1600x900 version. <key>PciRoot(0x0)/Pci(0x2,0x0)</key> ... <dict> <key>#AAPL00,DualLink</key> <data> AQAAAA== </data> .... --- I just updated the github release for Mojave config.plist files. Notes: i have been experimenting with 2 things to find more stable system VirtualSMC vs FakeSMC - uncertain that this has any effect - but it works - just get less sensors. and removing slide value - seems to be a little better?

roto31 Posted October 21, 2018 Share Posted October 21, 2018 I'm coming back to my Lenovo T420 after a LONG time away from this thread. Based on the kext packages from TLuck, am I right in my assumption that Mojave can be installed on the T420 based on the .plists as well? Or and I wrong in that assumption? Any issues with compatibility? I know support for Intel GMA3000 has been dropped from being supported in Mojave, what is the work around?

tluck Posted October 21, 2018 Share Posted October 21, 2018 @roto31 yes. for me mojave is running as good as high sierra - meaning there are the same glitches but there is not metal support so the light mode is not as good. you can read about the workarounds for HD3000 support in plenty of places. i explain it briefly in the guide. you will need to save a few files before you do the upgrade.

roto31 Posted October 21, 2018 Share Posted October 21, 2018 Not sure what I did wrong, but my T420 is stuck at 900x600 resolution. I've tried to boot with all of the Mojave compatible .plist files. I have not been able to get the Intel GMA300 .kexts to install? What is the proper way to install the .kext files to S/L/E ? Tried copying them directly - then running the permission fix. Used kext beast from tonymac.x86 and that worked to install the kexts, but I do not have acceleration.

Maybe this is just my experience, but I find Mojave more laggy than High Sierra, which I have now reverted back to. Not a big issue for me, as High Sierra has all the features I need.

roto31 Posted October 21, 2018 Share Posted October 21, 2018 (edited) After the resolution and acceleration frustration with Mojave I wiped the drive and installed High Sierra. During the install it had four separate spaces looking like 4 separate monitors. I figured it was a fluke and thought it might go to normal at first boot. The issue persisted. I’ve tried the default config.plist as well the the other 3 included .plists for High Sierra. Could it be something to do with the dual link display settings? *Update* I reverted to the EFI Folder that was from 10.08.2018 which was linked form the McDonnell Tech guide. I now have normal resolution no "multi-display" issue on the screen and things to be working fine. As much as I would love to have Mojave on this machine I think I'll stay with High Sierra. It'll get security and application updates for the next few years for sure. It's not a primary machine and more or less one to experiment with. In my number of actual Macs and Hackintoshesin my house it's #8. It's something I tinker with to keep my skills with OS X fresh and up to date. Working with and building Hackintoshes (especially laptops) have helped keep my skills on the inner workings of OS X up to date. Great job at being able to keep the T420/X220 series up to date with the macOS. It definitely helped those who cannot afford a Mac be able to have a "Mac", if you are willing to do some tinkering and some experimentation.

davidian Posted October 23, 2018 Share Posted October 23, 2018 Right now I have El Capitan on T420. If I want to try out Mojave on a separate partition, I should save the HD3000 kexts from ElCap, or first install HighSierra, save those kexts from HS, and then install Mojave?
