Flynn Huang Posted January 6, 2025 Author Share Posted January 6, 2025 (edited) After continuous attempts, I finally installed 10.12 The problems currently identified are: 1. When starting up, the screen will go black under the Apple logo. I will close the cover and wait for it to sleep and turning it on, so that it can enter the system normally. 2. WIFI cannot be enabled 3. The sound card cannot be enabled. The speaker can be used but the 3.5 interface cannot be used under Win7. Its cannot be used under macOS, possibly due to hardware issues I originally wanted to attach EFI, but this version is a clover and the file size is too large. Let's wait until everything is completely normal before uploading.
