    [Guide] Thinkpad T15 - Sonoma and OpenCore

    Bluetooth and Internal Camera Bluetooth will not work if MacOS does not see it on an internal USB port. This requires proper USB mapping. I used USBtoolbox on Windows for this. I would recommend using this over trying to map the internal ports on macos. The tool generates the map embedded in...

    [Guide] Thinkpad T15 - Sonoma and OpenCore

    I tried patching the IONVMeFamily kext, but no cigar. Finally, I decided to replace the Samsung NVMe with a WD one... and we're back in business - the installation completed without any kernel panics! Now working on post-install config. Will update as I make progress.

    Ah right... I meant is there a ref that i can use for patching kexts. I tried looking for it, but couldn't find any on patching kexts. I know how to do this in using Clover KextsToPatch, but i need the equivalent in Opencore,

    The Samsung drive is indeed a bummer! PM981 drives are notorious for kernel crashes under load. Mine is PM81a (MZVLB512HBJQ-000L7), but that does not appear to make a difference. I'm already using latest NVMeFix. Wondering if Find : f6c1100f 85410100 00, Replace : f6c1010f 85410100 00 in...

    [Guide] Lenovo Ideapad S340 Laptop on Catalina

    You're right the 10th gen intel processors aren't much of a upgrade from the 8th gen. But if you are at 8BG, the extra RAM is definitely worth it. Go for it! I will update my repo in coming weeks to the latest drivers and opencore.

    your computer looks same as mine, except for the processor. So, I think rest of the settings should require no changes for you.

    Well... I added the flag, and it seems to have fixed the problem! Thanks for pointing it out... sometimes you need to be pointed at the obvious. (I say seems to have fixed the problem because the problem is intermittent. I havent encountered it in my quick tests, but will keep a watch and...
