Hi folks,
When upgrading from 10.11 to 10.13 through policies, it fails the first time with the error "Unable to upgrade macOS", but seems to work the second time. but eventually works after rebooting and retrying - sometimes rebooting and retrying several times.
- I've got two policies, one to push the 10.13 cache, and one to install from cache.
- I wake the machine in the middle of the night (so it's been restarted since caching), and fire the policy.
- The policies trigger fine.
Policy shows:
Unable to upgrade macOS
install.log shows:
com.apple.OSInstallerSetup.error Code=219 Target is not convertible to APFS: This volume is not formatted as Mac OS Extended (Journaled).
However, the HDD is Journaled HFS+
(It's not SSD, it's a APPLE HDD HTS541010A9E662)
I don't understand why doing it a second (or third/fourth) time seems to make it work, but I'd like to concentrate on the first error above.
Thanks.
