Just been struggling getting Beta 4 installed on my M1 Macbook Air. Finally got it after a bunch of attemps. The key for me was using “Intel Partition Map” not the “GUID Partition Map”. (Helps when you look at the install guide on the website.). If you don’t it will install properly and then when you reboot it will only boot from the CD/Iso and the process starts all over again.
Trying to save you all from making the mistake I did.
Now onto figuring out how to get a lower resolution since Apple made a computer that doesn’t natively support 1080p. (Should have done more research before buying a year ago)
