What our friend is talking about is this, if the CFG setting in the BIOS (see attached) is locked or unlocked, the setting in the config.plist must reflect the same setting, if not the p/c will throw up a panic at boot.
Looks like I celebrated a bit too early. Now the system boots in Catalina, but there is still an issue.
- With Clover I was using itwlm.kext + Heliport app for WiFi.
- itwlm does not seem to be working with OC and Catalina.
- I thought it might conflict with AirportBrcmFixup.kext which I removed, and OC would NOT boot anymore.
- So I removed it and Heliport app and tried the Catalina version ov Airportitwlm.kext but didnt work.
- Just like with Clover, intel bluetooth drivers won't work.
And also,
The Mac Sur USB boot disk loads perfectly, but when I choose my SSD to install it, it loops back to the start. When I am in Catalina and launch the Big Sur installer, it crashes at the same point.
