Brand new Mac Mini with Mojave 10.14.1, new download of Lightroom Classic. I start LR and it crashes before opening. The log says:    "Nov 25 22:06:19 josephs-mini Adobe Lightroom Classic[874]: DEPRECATED USE in libdispatch client: dispatch source activated with no event handler set; set a breakpoint on _dispatch_bug_deprecated to debug"              I re-installed LR.  Same result.  Photoshop works fine.

Please give your Mac the "once over"! Run the free Onyx (https://www.titanium-software.fr/en/o...), reboot. (In Onyx just run everything in the Automation tab). 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. Check The Lightroom Queen site for instructions on how to reset your preferences (https://www.lightroomqueen.com).

Okay, but keep in mind, this was a FRESH install.  Brand-new operating system, new Mac, clean download of CC Classic. Nonetheless, I'll try what you suggest when I get home tonight.

I created a second admin user and it fired right up. No issues. I've seen other people with this same issue, and they solved it by creating a second user. This, of course, is not a solution. The admin user I installed with doesn't work, but the second admin user does. ????   A permissions problem????  I'm going to uninstall with the first admin user, install with the second admin user, and see if it works with the first admin.  If so, I'll delete the second user. I'll let you know how that works out.

Have you tried resetting your LR Prefs? LR Preferences Reset Procedure:

1. Close Lightroom.

2. Hold down [Alt/Opt]+[Shift] while restarting Lightroom. 

3. Overwrite the Preferences when prompted by the dialog.

4. Close Lightroom.

5. Restart Lightroom

I've done that. I've also uninstalled Photoshop and Lightroom, removed all files/directories in ~user/Library (cache, "Adobe", preferences, etc... Everything that said "adobe".).  I also ran the Creative Cloud cleanup tool that I downloaded. I rebooted and re-installed. Same result... It works with the second Administrator account I created, but not with the original Administrator account (mine).  I tried cleaning everything off again (as above) and installing with the second Admin account, and it installed and ran fine. I then rebooted and logged in with the original Administrator account, and same behavior. It pops up the flash screen for a fraction of a second, and crashes.  Bottom line:  I can run Lightroom with the second Admin account, but not with my admin account, no matter what I do.  I need to get my account working. I could wipe out my account and re-create it, but that's drastic, and there's no guarantee that would do it either.  I can include the crash file if you need.

Right, there's something in your ~/Library folder that's gumming up the works, is the only conclusion. Last Resort: Move your entire ~/Library to your Desktop as a backup. (That's your Username/Library folder, not the root level one, the one you can see when you hold down Option and click the Go menu, unless you've made it visible with the Unix command, then you can see it in your User folder). Move that to Desktop, then REBOOT. It will recreate a fresh Library folder with no preferences, does LR work then? If so, you would have to reenter all your serial numbers, reset all your prefs, but that would be a pain in the keister! That's why I said Last Resort. If it DOESN'T work, then move your Library folder BACK and reboot, and you're back to where you were.

Or: you could find the BEST Mac tech in your area, pay them whatever they want, and have them move all your data, change your shortname, etc. to your "2nd admin account", and make that one your first. Please DON'T TRY THIS AT HOME!
