I have Quicken Classic (Deluxe) 7.8.2 and it was working fine. Then I erased the disk and installed macOS 15.1, copied my files over, installed Quicken on the clean system, copied my Quicken file over and everything worked just fine, for several days.
But then today I opened it, and it is stuck on "Database Update", saying
Quicken needs to perform a one-time update on your Quicken files. This may take several minutes; please be patient.
I have been patient for several hours and it hasn't changed status at all. Now I see in ONGOING 6/6/24 Quicken Classic for Mac - Database Update Hangs that this is a known issue, but with no resolution for three months.
Until this is resolved, what can I do in the meantime to recover and make Quicken usable again — do I need to keep waiting, cancel, force quit or something else?
