lightroom classic crashes immediately going into masking (Sequoia Beta)

[davinder29725196v1c0]

hi, I have been experiencing this weird bug in my Lightroom classic where it crashes when I click for masks. I use a Mac studio with 64 GB of unified memory and an M2 Max chip.

I feel like It is Lightroom issues, not the Mac, is there anyone else facing the same issue?

so MACOS Sequoia Preview

Not yet supported in LrC. So no surprise things fail.

is there anyone else facing the same issue?

Yes.

Some members that have done that have had a little success followed by failures, Some have had no success. Their are several posts in this community on that.

You may need to wait for a LrC upgrade (perhaps a update) or revert your MACOS.

Running a Preview OS, much less a Beta OS on a working computer (as opposed to a test computer) is often a very bad idea.

None of the "workaround" work for me.

[JohanElzenga]

Please do not post more reports about this issue. Lightroom Classic 13.4 is incompatible with MacOS Sequoia. That is known, confirmed, and Adobe (or Apple) will have fixed this when MacOS Sequoia is officially launched and a compatible version of Lightroom Classic is officially launched. There is no need for more "me too" posts in the meantime. If you want to work with Lightroom Classic, then use it on a version of MacOS that is supported.

Reinstall Sonoma and be glad that you haven't lost data.

[AxelMatt]

Please try is to switch off the GPU support from the Lightroom preferences and check if that helps to fix the issue.

Go to Lightroom > Preferences > Performance tab > Uncheck "Use Graphics Processor" > Restart Lightroom.

Another step is to try to reset the Lightroom preferences.

It's recommended to backup your preferences before you reset the preferences to the default settings:
