Sequoia... anyone?

15.5 has been the most stable for me thus far. (MacStudio M1Ultra), not certain re the rest of your kit.

Does anyone know if macOS 15.5 has issues with PTU 2025.6?
Is it safe to do a system update?

my relevant gear:
Pro Tools Ultimate perpetual running in Rosetta mode
Mac Mini 12-core M4 Pro 24GB memory
Avid Sonnet PCIe expansion chassi with HDX card
multiple 96io interfaces
D-Command main and fader expander

Thank you.
I found an updater for 15.4 here:

Is it safe to use this?

I updated to OS 15.5 yesterday and the very first time I opened PT I had major video engine issues. Crashes, couldn't restart, etc. I restarted the computer and it's been fine since.

I updated to 15.4.1 from there 2 days ago. Worked well so far.
