Exit after Preparing

Opened this issue · 3 comments

Hello, we're seeing the script run and start to run the installer, but after Preparing to a certain percentage it just seems to stop and exit. no other information. Anyone else see this or know of a fix? Happening on Mojave 10.14.6

from startosinstall.log:

One more update, we are seeing that users who manually run Install macOS Catalina.app are not seeing this issue. I do also have a case open with Apple to see if they can find anything specific in the install.log. But nothing yet.

I am intermittently seeing a similar issue when attempting to update a Catalina Mac with Big Sur. One time, the % got all the way to 95.3 before stalling. If I open the same installer app locally, it opens within 2-3 seconds.

JAMF-1980131 is the Jamf case number if anyone needs it. I was asked to run “sudo '/Applications/Install macOS Catalina.app/Contents/Resources/startosinstall' --agreetolicense --forcequitapps” directly and see if the issue still happens, but haven't had an affected user able to test yet.
