P: Support for macOS Sequoia

According to the link below, lightroom classic and photoshop (and many more adobe apps) are confirmed to be compatible with macOS 15 Sequoia. But it doesn't mean there are no problems...

My computer was updated to Sequoia automatically unfortunately, and while editing pictures in Lightroom Classic still works, tethering does not for me. The app can't find any connected camera and just freezes.

First website I found with any news regarding this. Not much help though, but maybe in the near future...

Traditionally, and this is going back 10 years or more, Adobe does not tend to declare support on day one of a new macOS release. Each product team typically publishes a compatibility report or release some time later.

A big reason is that many developers (not just Adobe) like to test with the actual .0 release that the public gets. User often say “But isn’t this what the beta period is for, weren’t you testing with the beta all this time?” And usually, yes, they were. But many developers have been caught by surprise by late Apple changes between the last beta release and the first production .0 release that broke something in their software. So they are now not comfortable saying “yes, it works!” until they have time to run the actual .0 release through whatever their test suite is. And that test time starts from the day it’s released, which is today.

I also did a quick search for any new Adobe documents about Sequoia compatibility, but I don’t see any yet, but again, I’m not surprised…for the reasons above.

Personally, I don’t upgrade macOS until 6 to 9 months after it’s released. I like to wait out all of the early release bugs and not waste time troubleshooting things that Apple will fix in a couple of months. And remember, it’s never just about one application like Lightroom Classic…it’s also about everything else that it has to work with, like my printers, my display profiler, my graphics tablet…I have to wait until all device drivers I use also declare compatibility with the next macOS.

There is a page on Adobe's site that usually shows what bugs are found with each release. I have been looking for it myself and can't find it...

I'm pretty sure that the current version of Lightroom Classic (13.5.1) will have issues, so my advice is not to upgrade to Sequoia yet. Wait for a Lightroom update where Adobe says it's compatible.

Adobe normally publish a document a few days before/after OS release advising of any issues that users may experience.. Therefore, if you don't absolutely need to update the OS it might be wise to wait a day or so before upgrading.
