P: Hanging on launch (Mac 10.14.6)

I'm with you Tim, I'm staying put at MacOS 10.14.5 (LR 8.4)! Panos still good!

I've not 'Me-too'd" but I can report 8.4 is working fine here.  Difference is I've not upgraded to Mac OS 10.14.6 - still on 10.14.5 and now nervous to make the update!

I've got one by email on Windows 10, but it may not be exactly the same issue.

For those who have "Me-too'd" this thread. Is there anyone who is not using 10.14.6?

I've run Onyx and run disk first aid, unfortunately this has made no difference to V8.4.

I can open a new catalogue from the Option Key, but nothing else. Existing Catalogue and Backup catalogues do not open.

So no change, I went through a major support exercise with Apple as part of this and they couldn't find any OS issues, but did manually clear all the Lightroom caches.

Just to rule out an issue with MacOS: It may be a corrupt cache or application state, or directory damage. Please give your Mac the "once over"! Run the free Onyx (https://www.titanium-software.fr/en/o...), reboot. (In Onyx just run almost everything in the Maintenance tab, deselecting things you may not want deleted, like Launch Services . Hit the "Options" button and deselect more stuff like Cookies & Other Site Data, Browser History, Form Values, etc.), then hit Run Tasks. After it's done it will ask for a reboot.

If that doesn’t fix it run Disk Warrior if you can ($120), (https://www.alsoft.com), reboot. If you can’t do Disk Warrior, at least run First Aid from Disk Utility. Also just doing a "Safe Boot" can clear out caches (restart, hold down shift until you see "Safe Boot" on the screen, then reboot normally.

If that doesn’t work try launching Lightroom from your other (admin or test) account, with a new catalog, as a test. Does it run OK? If it does it may be a corrupted preference in your Username/Library folder. Reset your preferences (https://www.lightroomqueen.com).

I spent over an hour with Adobe support chat taking control of my mac and tried twice to reinstall never fixed it. I don't think he tried alt/new catalog method but not sure. Never worked. I was using 8.3.1 but he recommended I go 8.3 so running that now. What a waste of time. Adobe needs to review their test base and make sure they are testing on enough scenarios so these bugs are not passed to paying consumers.

I've updated to v8.4, and the program hangs on start up.

I have spent over 10 working hours on the support chat lines to Adobe so far without resolution of the issue, rolling back to V8.3.1 has allowed me to open all my catalogues successfully.

Issue:

When opening an existing catalogue the program hangs and shows "program not responding" nothing else seems to happen.

Opening a new empty catalogue initially wouldn't work and Adobe support sent me off to Apple to resolve this, Apple deleted all the cache files and then it would open an empty catalogue OK and allow me to start with new photos.

However the existing and backup catalogues simply hang the program.

Catalogue has been sent to Adobe for "repair" it still wouldn't open the repaired file.

System is an iMac 27" (model identifier 17.1) 24GB memory, upgraded to SSD.
OSX 10.14.6
Lightroom Classic v8.3.1 or 8.4....

I've not managed to get it to launch while holding down the Opt  key, but it would launch from an empty catalogue.

I've gone back to 8.3.1 now so can't retest at the moment.

A long shot, but if you create a new catalog while opening (hold down the Opt key while starting LR), does that work? No need to import photos (I just have a suspicion), just see if it opens ok in 8.4.
