OK, now I'm having a different issue trying to install El Capitan Public Beta. When I run the installer and it shows me available disks for installation, my boot drive is greyed out, and when I attempt to select it I get the message:
Code:
This disk cannot be used to startup your computer
even though it's the disk I started up from!
I googled this error and all the answers I found point to this Apple KB article:
https://support.apple.com/en-us/HT203482. Great, except the tip in the article doesn't work - I resize the partition, reboot, and still get the same error when I try to select my boot drive for installation!
I've also tried booting from the USB installer I made instead of just running the El Capitan Beta installer from my booted system, but I cannot get the USB installer to boot (separate issue I assume). What can I do to fix both of these problems?
For the record, my system has two drives:
- disk0 = 512GB SSD with two partitions (EFI and /)
- disk1 = 960GB SSD with two partitions (EFI and /Users).
I'm using Clover (latest version r3259). I really, REALLY don't want to format and do a clean install - that would be pretty painful, despite backups.
