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've been using Lr/Ps for a while now with macos 26.01 without any problems.

Hello,

I’m having a persistent display issue in Adobe Lightroom Classic when entering fullscreen mode on my external monitor.

System setup:

• MacBook Pro 14" (M4 Pro chip)

• macOS Tahoe (latest version)

• Lightroom Classic (latest version)

• External monitor: BenQ 3225U connected via USB-C

Issue description:
When switching to fullscreen mode on the external BenQ 3225U, Lightroom’s interface becomes distorted — the top black bar stays visible, the image area doesn’t scale correctly, and parts of the interface freeze or disappear.
The issue began right after updating to macOS Tahoe. Everything worked normally before that.

I’ve tried:

• Resetting Lightroom preferences

• Reinstalling Lightroom

• Testing different cables and ports

• Enabling/disabling GPU acceleration

The issue persists.

I’ve attached a screenshot showing the problem in action.
Could you please confirm if this is a known compatibility issue with macOS Tahoe, or provide a possible workaround?

Thank you for your help,
Jakub Machala
