Latest (Beta 3) Important Content Missing

Afternoon all,

Not sure if this has reared it’s ugly head yet for anyone else but I’m getting an installation bug whereby I can’t boot into the running macOS Beta 2 and am being forced into installing Beta 3 upon startup.

When I try to install it, I get this error pop up. (See photo attached) does anyone have any idea how this can be rectified?

Would anyone know the dialogue I’d have to put into Terminal to delete the installer? As I can’t log in to do this the normal way.

Anyway, any help is appreciated!

Thom

Have you tried holding the Option key as you boot, and seeing if your HD is still in tact to boot from your previous build? I got that error on my first install attempt but before it has restarted, the restart phase wouldn't kick in. The Installer itself would be in Applications, you should be able to delete if you can boot with the Option key. If that doesn't work try an SMC reset to try to boot. Hopefully someone else can chime in. Good Luck
