P: Mac Beta OS (Tahoe) Issues

[kimaldis]

All of a sudden my dialogs have become unreadable. Anyone seen anything like this? I'm also losing the brush disks in clone, remove and masks, which may be related.

@kimaldis Are you on MacOS Tahoe Beta4 (23A5297i) ? We've been seeing similar issues with Beta4.

I'm on  Tahoe Beta (25A5316i) I see a Tahoe update, KYP

OK, it seems to be something to do with the Apple Studio Display. If I bring up an LR dialog on the Display it's all messed up. If I drag it over onto the Macbook display it fixes itself. Stays fixed when dragged back. Annoying but at least I can get to see what's in the dialog now.

Thanks so much for sharing that update, @kimaldis! This insight about the Apple Studio Display and how moving the dialog between screens affects the issue is really helpful. It will certainly assist Krishna and the product team in investigating compatibility with the latest macOS Tahoe builds and Studio Display.

We appreciate your patience and for taking the time to test this. If you notice any other patterns or changes after the update, please feel free to share them here. it really helps us get to the root of the issue.

Best,

Im not sure what happeend but i opened Lightroom Classic today and the "Copy Settings" and 'Preferences" tabs are blacked out, not sure how to fix them. Ive tried to restart the aplication, downgrade and re upgrade the software, uninstall and reinstall the aplication as well as restarting my computer (macOs)a and making sure my software is up to date. If anyone has any recomendations id love to hear them, Thank you!

Try to reset the preferences of Lightroom Classic:  How to reset Lightroom Classic preferences (adobe.com)

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

This didn't work for me but the situation has resolved now with installation of Tahoe Beta 7.

[Vidhya S]

 Can you please update your OS version

[JohanElzenga]

Let me guess: you use MacOS 26 beta? This is a known issue for that beta, and a reason not to install beta OS on a production machine.

Update: After reading through everones replys, it has to be a  macOS beta thing, im also on Beta 26  (my first time trying beta software, never again lol). if i drag the "copy settings" tab over to my second screen and back it resets it self, super weird. thank you everyone for the help!

Me pasa exactamente lo mismo. Tengo la versión beta publica de OS 26 Tahoe. 

la solución momentanea es conectar un segundo monitor a mi Macbook Pro, arrastrar el cuadro de dialogo y volver a traer el cuadro de dialogo a la pantalla principal, es un poco tedioso pero por el momento solucióna el problema. 

Les dejo un video explicando un poco.

Make sure you report this via the Apple feedback app. That's the entire purpose of a public beta, its NOT for you, its for Apple and developer testing and reporting. We don't recommend using the betas for production work as they are unfinished and a pain to roll back to the release OS.

Macbook Pro M4 Pro. Lightroom Classic, Latest Version

The SYNC ALL dialog box is useless. I have removed the app and resinstalled. The same problem occurs. The box is all black and no text can be read.

[kimaldis]

drag it to your other monitor and back.

[raymondt7796285]

I only have the MacBook, no other external display.

[kimaldis]

It does it on all dialogs unfortunately, I guess I just struck lucky with having a second monitor. I found I could also fix it by scrolling the dialog contents but the sync dialog doesn't scroll. Best I can do, I'm afraid. Sorry.

[kimaldis]

I just found this. With the dialog open: 

System Settings->Accessability->Display,  toggle Increase Contrast on and off.

Hello, my Lightroom Classic has a bug where using the copy or sync window displays black icons. The same black window also appears when saving a preset. 

My Lightroom is fully updated to the latest as of today (04.08.25)

My macbook is running a developer beta (MacOS 26, Tahoe), so I assume this has something to do with it, but i'm posting to see if anyone has had a similar issue on previous MacOS software.

[JohanElzenga]

Known issue. Don't install MacOS beta software on a production machine!

[raymondt7796285]

I understand not using beta softwae on production machines. The Macbook is not my main machine. I just Adobe would like to know there is an issue. Adobe should work with Apple to resolve the problem, not the people running the beta softwae. There is an issue with Lightroom and MacOS 26. I guess from the response from Adobe that Adobe really does not care and stays with their basic corporate philosophy that the users are stupid and only Adobe knows what is best.

[ExUSA]

See, its not a problem. Beta software is expected to have issues and in many cases, developers cannot implement a fix until later in the beta cycle (maybe its a known bug and Apple is working on a fix?) And Apple has a feedback app with the beta, they ask that you make reports thewre, NOT in developer forum. That's how both Apple and Adobe get beta bug reports.
