Adobe Photoshop issues after macOS Tahoe installation

I would give anything the go back in time two weeks and not install that OS. Nothing but trouble, and be aware that you can no longer back install to past OS. Particular problems with Adobe, especially Photoshop. Apple keeps pulling my warnings about this without explanation. My Apple Care is current, and I need this solved.

Interesting discovery this morning. When I'm working with photos, I almost always open the file from Bridge. This morning, I rebooted and launch PS but did not launch Bridge, opened two jpegs from the finder instead, and PS is so far behaving normally. Haven't worked with this much, but did some generative expand and cropping and so far so good.

Could this be a Bridge problem, and do you have any recommendations for me?

Sure sounds like a Bridge issue (?)

the advise is the same, for your third party app search the developers website if in doubt.

Run Etrecheck and paste the full report in your reply as outlined in my post above.

Do you have any external drives? If you do are you using it for the cache/swap files for Photoshop?

If not how much free space do you have on your boot drive and how much RAM do you have?

Have you installed and run any "cleaning", "optimizing", "speed-up", anti-virus or VPN apps on your Mac?

What Photoshop? The current version of Photoshop CC is running fine with Tahoe. If you have an old version of a perpetual license or an older Elements, that’s not Apple’s fault for updating macOS.

Always make sure your critical software is compatible with a new OS before you update.

Not for me. Do you have extensions/plug-ins that may be causing issues? I run PS pretty clean, I have the Nik plugins but that’s pretty much it.

WHat's the problem with Photoshop? And what version? And as it's a 3rd party app your best seeking assistance from the makers - Adobe. FWIW the current versions run fine here

I am experiencing general slow performance in opening files and then it is showing up as a long lag when using a tablet. I am using an Xeance Labs tablet and updated drivers to 1.3.5-89. It seems to be a brush compatibility issue as I can select different brushes with lower point numbers like a smoke brush and the lag is not always present. However when I use the pressure sensitive brush for opacity and flow the brush strokes appear about 1-2 seconds after I have painted. It also seems to not be accepting the pressure sensitivity. While this is a photoshop thread I am also experiencing significant slow downs with Lightroom and copy and pasting settings between images that I have never experienced before.

Pushing the issue — Photoshop is lagging after macOS Tahoe 26.0 update, its essentially unusable. Updated PS to Version 26.11. Still didn't make a difference. Clicks aren't registering, hanging up on tool changes, buffering on everything. In comparison, Illustrator runs just fine with no issues.

PS (26.11) is running fine on my M4 Pro MBP, last week under 26.0 and today on 26.0.1. There seems to be a deeper issue with your system.

Idk man Im on the newest version of photoshop and its literally running at a snail pace, to the point were switching between tool scan take up to a minute
