Our kext now works on Big Sur Beta 7. Great!
I'm asking in another thread (https://developer.apple.com/forums/thread/662896) and I've built a KEXT that uses IOSCSI and confirmed it works on macOS 11 Beta 9. KEXT is loaded, but macOS crashes when I call the KEXT API from application.
I build KEXT using Xcode 12.2 beta2 on macOS 11 beta 9, but please let me know if there is anything else I need to be aware of.
Note:KEXT and installer pkg is signed with kext developer id and Notarized.
