There are a lot of ways a system update can fail \u00a0and FWIW, my Studio upgrade to Sonoma did not go well.(Update on the laptop went fine, however.)<\/p>\n
On my Mac Studio, I got an incomplete install with an infinite loop of reboots:<\/p>\n
Got to the second reboot, with white logo and thermometer and then \u00a0got stuck in reboot loop cycle at about 2\/3 done.<\/p>\n
So, I did a restart in recovery mode and tried an install from there. Same thing, but this time instead of just a loop of \u00a0reboots, I got a message that there was “no administrator “on the machine, and install could not recover.<\/p>\n
\u00a0<\/p>\n
Here’s how I got out of that:<\/p>\n
Opened the Terminal and entering<\/p>\n
\u00a0 \u00a0 \u00a0 \u00a0 \u00a0rm \/Volumes\/OSX\/var\/db\/.AppleSetupDone<\/p>\n
(where OSX is my main volume name, so you’ll need to replace it with your own volume name.)<\/p>\n
NOTE: \u00a0(Do this carefully if you’re following along at home: “rm” is “remove” and you don’t want to mess that up! \u00a0Copy\/paste is a good idea.<\/strong><\/p>\n \u00a0<\/p>\n Next I rebooted back into recovery and using the “reinstall Sonoma” almost<\/em> worked this time. At least it seemed to complete.<\/p>\n However, when I rebooted again, I found myself stuck at the 2\/3 thermometer, so I powered down and unplugged all “extra” cables from the studio (USB, Thunderbolt etc) and rebooted. This time the install completed 100%.<\/p>\n I then reinstalled all the cables and things seem to be working OK.<\/p>\n HTH someone.<\/p>\n \u00a0<\/p>\n Tracy<\/p>\n \u00a0<\/p>\n \u00a0<\/p>\n","protected":false},"excerpt":{"rendered":" There are a lot of ways a system update can fail \u00a0and FWIW, my Studio upgrade to Sonoma did not go well.(Update on the laptop went fine, however.)
