Original Question:

Installed to external SSD and it loads wonderfully. Thanks to the help of u/Frzngrape and u/Nobbylobo. OS is fast and very stable atm. Touchscreen and trackpad are working. My only problems are: No graphics acceleration (7mb vram) No battery indication Trackpad force touches with every click, probably because of #2 No audio I'm relatively new to this and seems pretty obvious to me that all of these problems are caused by the errors I've highlighted in the log on the left-hand side"prelink injection whatevergreen.kext - invalid parameter" and etc. Anyone have any ideas? https://preview.redd.it/9o7o3dz8uc471.jpg?width=1920&format=pjpg&auto=webp&s=e4a63c347da71e487dc5d5a2e5f4af4b98724ec5 submitted by /u/clear_simple_plain [link] [comments]
