MacOs Tahoe, MacOS 26

[moordavidphoto]

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.

I will be patient and update when there is an update of the OS. I had issues with my old mac a few years ago and I don't want to go through that kind of hell again...

One caveat if you have a Wacom tablet. The latest tablet driver 6.4.10-3 is having issues, Wacom recommends installing the previous 6.4.9-2 driver version. I ran into this on my Intel MacBook Pro but I didn't see the issue on M1 and M3 Macs in very limited testing.

Thank you ExUSA. 
Today I upgraded to MacOS 26.0, Lightroom and Photoshop worked fine, until I saw your suggestion : indeed, Wacom tablet not working properly.  Removed old driver and software, installed 6.4.9-2 and everything is fine now. 

Upgrading the OS is always a risk .....

ExUSA, thanks !

As soon as I updated to MAC OS 26 Tahoe, my Acrobat is "RIDICULOUSLY SLOW"! I can be editing a PDF and add a text annotation to a PDF and it will literally take between 1 and 3 seconds for each letter to register after I have already typed in the annotation paragraph. UGG> HELP!!!

You've posted in the Lightroom Classic forum. I suggest that you raise your issue in the Adobe Acrobat forum.

Can confirm that Lightroom Classic is unusably slow in my M1/64GB after updating to MacOS 26

I'm very miffed Adobe hasn't updated Illustrator or Photoshop yet.  They should have been working on this months ago knowing there was a MacOS upgrade coming.  I feel they hold users hostage from upgrading to MacOS Tahoe.

It’s the same every year. Indie developers have their apps ready on launch day of new macOS versions, yet Adobe doesn't even update the page about macOS compatibility. I’m sure Adobe will continue to ignore macOS 26 Tahoe until the Adobe MAX event at the end of October.

True and we pay a reasonable amount montly to use the software so it would be very convinient to adapt to the latest MacOS version within a periode of one month.

Well, who do you go to instead? I just visited the website of a Lightroom competitor, and their system requirements still say “macOS 13 or newer (tested on macOS 13.7.6, 14.7.6 and 15.5)”. No macOS 26 statement yet.

I also checked a different non-subscription Adobe competitor. Tahoe is not listed on their system requirements yet either, and their forums say there are problems...

I don’t think there is any "hostage-taking" on anyone’s part. All these companies are probably validating the actual 26.0 release which may have different bugs than any of the betas. It’s always better to wait for everybody’s (Apple’s and developers’) bug fix updates, instead of risking the stability of a workflow by upgrading too soon. This is from watching this same thing happen every year for decades…

[ExUSA]

When I worked at Apple, IS&T upgraded machines on launch day every time. But for non-experts who need a reliable workflow, it is probably best to wait a bit (I upgraded all three supported Macs but I'm more experienced than the average rabbit.)

There's a pinned post on the Photoshop forum that includes a Reddit post that may offer some insight and workarounds for issues caused by macOS 26 Tahoe.  I've provided links to both below

I would suggest waiting until at least macOS Tahoe 26.1 (it's currently on 26.0.1). It used to be that installing the latest macOS was a no-brainer, but since the mid-2010s, it's been more like Microsoft Windows used to be—i.e., you can install the OS, but chances are some of your software will no longer run, or at least no longer run properly. With Sequoia, for example, I waited until we were several months into 2025 before finally installing it.

[moordavidphoto]

After several of my colleagues told me that they were running Adobe software without any problems after updating to Mac OS 26, I also tried it and updated to 26.0.1. Lightroom Classic, Photoshop, and Photoshop Beta run without any problems or errors, just as fast and reliably as before.

[Bertd]

Thanks for the update! I wonder if there are any users which do have already experience with InDesign under MacOS26.01?

[Ian Lyons]

I recommend that you ask in the InDesign forum rather than here.

This looks like a general and common social media response.....it was just a observation.

Just to speak from experience on this, I am running Lightroom Classic 14.5.1 on a MacBook Pro 14" M4 Pro 48GB and there are some issues.

Performance isn't great at times, having to restart Classic a few times a day. I'm having random window issues where I have to go to Window-Fill to bring the window back. Typing in the Keyword box is extremely laggy, had never expeirenced this issue before. I use LRc all day each day and it's not show stopping stuff, but looking forward to an update that I hope will address some of these issues.

There is a known issue with Electron apps, apparently the framework developers did something stupid and used a private Apple API which then changed and caused slowdowns.

Although the Adobe compatiblity page doesn't yet include the MAC  OS update to Tahoe 26 for Lightroom Classic, I am wondering if anyone out there has in fact updated to it and if so, are you having any issues? 

[ExUSA]

Many of us are using tahoe without major issues.

Adobe MAX conference is this week and new app versions will be released, we should see Tahoe compatibility plus added support for ARM on the Windows side.

[DenmarkOne]

With the release of LrC 15 im a bit dissapointed to still not see tahoe 26 mentioned here: https://helpx.adobe.com/download-install/apps/system-requirements/apps-compatible-macos.html

Is it still not ofiicially compatible?
