Title says it all, so I get to 5 minutes left, and then the error message 'failed to prepare update' appears. I've done this for about a week now and the same thing happens. Does anyone have any insight to this problem?
iMac M3 Tahoe 26.4 beta 2 not updating
I have a Mac Studio Ultra M3. I’ve experienced the same issue for the past 8 days, first with 26.4 beta 2 and now with beta 3. They simply won’t finish downloading. Tried safe mode, no joy. This is annoying as all get out. Beta 1 installed with no problem except for the pesky issue of HFS+ volumes failing to mount.
