Has anyone tried Mac OS 26 RC? Are Lightroom, Photoshop, and the Creative Cloud app now compatible with Mac OS 26? I've never updated a Mac major version since I switched to MAC, so I don't know if it's worth waiting for it to work reliably and stably, or if I can just go straight to the new system on September 15th. Thank you in advance for your answers.
A good thing to do is bookmark the Adobe compatibility article link below, and check on it until it’s updated to cover macOS 26 Tahoe. It lists the last few versions of macOS, indicates which versions of Creative Cloud apps are claimed to be compatible, and any known issues. The Known Issues column is pretty quiet now, but when macOS 15 was first released there were a lot more items in there.
Adobe apps compatibility with macOS
In addition, Adobe may post an article specifically about macOS 26 alone, similar to the one below that they posted for macOS 15 Sequoia:

Those articles may or may not be updated on the day macOS 26 is released. Realistically it may take a few days or even weeks. This is because Adobe is like a lot of software companies in that they tend not to declare compatibility until they have had time to test with the final .0 release of a major new macOS upgrade. They often won’t declare compatibility based on beta OS test versions because even though all major software companies test their software on those, in the past some did claim compatibility early but ended up burned by new OS bugs that turned up in the .0 release that were not in the last test version and broke the software.
Every time there is a major OS upgrade, if you have workflows that you can’t afford to have new software break, the best thing to do is not upgrade until you have seen compatibility statements from all of the companies making all of the software you use. That includes the companies who made your accessories, like printers or other special hardware that depend on device drivers that must be compatible with macOS 26 too. If you need absolute certainty for your specific combination of software and hardware, create a test macOS 26 system to boot from (such as on an external SSD) and test out everything that needs to work, before installing macOS 26 on your production Mac.
I usually wait several months before upgrading, and that means everything keeps working. By the time I get around to upgrading, all the software and drivers I use have had time to iron out any bugs related to the new OS.
