Export causes a system hang

Not sure what's going on, but all of a sudden I'm finding that Lightroom CC on my MacBook Pro is wildly unstable. I've scanned a bunch of freshly-developed 35mm film and imported about 200 TIFF files. I'm able to work (light edits, crops, etc.) for about 15-20 minutes max before basic tasks like "Export to JPG" or even just quitting the app cause it to pinwheel, forcing me to do a "force quit" just to get past it.

 

I'm on Lightroom CC version 9.0 (20251017-1944-414afc8 Build). My MacBook Pro is a beefy M4 Max running macOS Tahoe 26.1 with 48GB of RAM and plenty of open space on the SSD.

 

Any tips or suggestions would be really appreciated, this constant freezing is bumming me out...

@Huxley5CC4 we have something more concrete for you to try. Please go into Lightroom > Preferences > Interface, and under the HELP section, turn off "Enable Animated Hover Tips". This will stop the small animation that appear when you hold your mouse over an Edit slider, among others. Does that help at all?

Hi @Julie Kmoch & @Sameer K - thanks for the suggestion. I've disabled Hover Tips and for the first time in weeks I was able to get through an entire import/organize/edit/export session followed by quitting Lightroom, all without any freezes or crashes. Totally bonkers that this might be the solution, but here we are! I'll update again if the crashes come back, and I hope that whatever bug this is gets resolved ASAP, as I do find the hover tips helpful. 

 

Happy New Year!

We're noticing a common theme in your crash logs involving video or media playback. Do you have videos in your catalog that you're interacting with when Lightroom hangs? Or are you playing any videos or music in the background?

Hey, @Huxley5CC4. Welcome to the Lightroom Community. I'll need more info to help you figure this out. I found crash reports submitted with the account you've signed in to on the community. 

 

Did Lightroom close normally the last time it worked, or is this a fresh installation of Lightroom v9.0 on this machine? Try these steps to get Lightroom to launch:

  • Reset Lightroom by holding the OPT + SHIFT when you launch Lightroom and select 'Yes'.
  • Ensure Lightroom has the required permissions on macOS: https://adobe.ly/3DyUwsz
  • Go to the following location to launch Lightroom via the terminal.
    In Finder > Application Folder > Open Lightroom Folder > Right-click on Lightroom .app > Show Package Contents > Contents > macOS > Lightroom—double-click to open.

Share the log of what you see in the terminal window when Lightroom Launches. 

 

Let me know how it goes. 

Thanks!
Sameer K

    Hi @Sameer K - thank you for the suggestions! Here's a few quick replies:

    • I did the Option + Shift thing and accepted the reset, but the app is still hanging frequently (i.e., it stalls out every time I try to rotate a photo, and after that happens, attempting to quit the app freezes entirely with a pinwheel cursor)
    • I have manually added Lightroom to the Full Disk Access permissions - no change in behavior 
    • I'll attach a screenshot of the Terminal output after launching Lightroom from within the package as you instructed. I will admit that it's amusing to see the log output state in multiple places that whatever is going wrong "...

      may cause spurious casting failures and mysterious crashes." A pretty good description of what's going on!
