    Lenovo ThinkPad T420 with UEFI Only

    Nice! Maybe indeed if I throw more memory at it, the glitches will go away - I'm running with 8GB at the moment on X220 (1366x768).

    Are you sure about the glitches?

    Lenovo ThinkPad T420 with UEFI Only

    I've just downloaded dosdude1 patcher, created the media and then added tluck's files on top of that in the EFI partition (as described in the guide). Then booted, made a fresh install of Catalina, rebooted, applied the patches from the media again and rebooted once more - everything works out of the box. I don't bother to install the kexts locally (is that even possible with Catalina?)

    I've actually did a fresh install of Catalina (dual booting with Mojave for now) using the dosdude's patches and tluck's files and everything works out of the box - sound / network / bluetooth (I run this on x220). The only thing that still bugs me are the glitches. I still cannot understand what triggers them - sometimes they are completely gone for a long time, sometimes they just start appearing. Anyway - I'm still quite impressed to see these machines running the latest macOS, without sweating :-)

    Quick report: I've just upgraded my Thinkpad (X220) with the latest 10.11.4 update and at least for now (like 10-15 minutes browsing / youtube etc.) it seems that my machine is not affected with these glithes you are discussing. The bios version, if that matters, is 1.39 modded (whitelist removal). Although there is newer version - I found 1.40 modded and there is even newer 1.42 on the lenovo site, I've decided to go for the update and see how it goes and then update if needed. If I observe any strange behaviour I'll report back, but for now maybe for X220 users 10.11.4 is good to go. EDIT: Today, after maybe a total of 10 hours usage I've got the first complete system freeze. It seems that in the end I'll need to update the bios and see if this persists. Beside that freeze, I still haven't seen any glitches as the ones discussed above. EDIT2: Here comes the artefacts

    I'm on El Capitan since the betas - never had an issue, besides the applications that fail to play nicely with the new SIP (like XtraFinder for example). Generally speaking the switch for me was much more effortless then the Mavericks->Yosemite one last year :-) Just don't forget that you need not only to install the kexts, but also to copy them over to EFI/CLOVER/kexts (like during the initial installation). Also using the provided from @tluck script is the better way to go as it also cleans old obsoleted kexts.

    If you followed this guide - there is nothing special to do - just go to App Store and hit Updates - I'm not sure though how to update exactly to 10.10.4 as the latest version is 10.10.5 (most probably you would need to go through each update up to 10.10.4 and then stop there - do not apply the next one)

    Yes, indeed you need to revert back the changes for the USB3 XHC1 controller, but for me everything is working even with default configuration with the name set to SLOT. I start to wonder if there would be any benefits of changing it to GFX0 (for example I'm missing the audio-over-HDMI).

    Hi everybody! I have this really huge, huge problem bugging me all the time. And it is the fact that I never had the chance to thank @tluck and the whole community around this thread and forum. So without further ado: Thank you @tluck and thank you community! For the continued support and all the help that you provide all the time no matter how "stupid" or simple the questions are Thank you @tluck for constantly updating the install instructions (I've started following this thread around one year ago, but it seems that you are doing this for two years now). Thank you everybody for building this comprehensive set of knowledge for creating (I may be biased :-) one of the most polished/seemless (I would say even hackless) hackintosh builds. One year ago I was at point zero when I guy told me "You know - your X220 could easily run OSX" and I was like "OK, why not - for a sysadmin with 15+ years experience in the linux/windows world that should be a no brainer" . And two weeks later, after wrestling with all the "new stuff" like kext, clover, chameleon, dsdt, ssdt, bios whitelisting, MBR patching etc. and my head was about to explode I came upon this island of knowledge where all the pieces just fell in place and everything started to actually make sense: - You want native updates - here you go - You want native installer - serve yourself - You want external VGA monitor through docking station - be my guest ... Actually the list of what is working seems to be endless - the build is so solid that I've even managed to plug an external Nvidia GTX 760 GPU (through ExpressCard slot) and use dual VGA/DVI external monitors setup (through docking station) and it is still working as expected! A must admit that I had to dig into the dsdt to make the eGPU working, but again thanks to @tluck, who has comments for all changes/patches inside the dsdt, I was able to quickly find myself around and fix the problem. Thank you all, one more time - you've managed to convert and 18 years linux desktop user (a KDE user) into an OSX fan (still not a mac fan though). You are all truly insanely mac P.S. I'm writing this from fresh El Capitan GM Candidate1 install on Thinkpad X220 using only the dsdt, clover config and kexts provided from @tluck, eagerly waiting for the final El Capitan GM Release
