Beta 2 Can't Install on my Beta 1 Mac
Same issue, I tried DIsk Utility on both data and solid Mac HD. I also ran installation DMG Developer Page, Restarted trying again
I got this message too. But I tried again and it got past this point. It is currently at “21 minutes remaining...”
There is a thread at macrumors.com about this error message also. Someone there said that booting into the recovery partition (with cmd-R) and repairing both partitions with disk utility will help get around this.
Any luck? Having the same issue.
I did just that repaired both disk containers. Then downloaded profile from Apple developers page and was finally able to get it installed
I got the error first time, I just opened the installer again and it worked the second time.
Running the installer a seond time does seem to work.
