Hi Mac Poser peeps,

I'm itching like crazy to install and run Poser 13 on my mid-2010 6-core Mac Pro tower, which is currently running Poser 11 Pro within High Sierra, but have to jump through a lot of hoops to install, say, Monterey or newer using OCLP on the second hard drive.

I think I've seen people say they're running P13 on Sequoia, but I'm not sure, and I don't think they stated which Mac they're using it on. I do know that Monterey is the oldest Mac OS X version that P13 will run on, but if possible, I'd like to go with a newer version so I can also upgrade Photoshop. Many thanks in advance for your input!

It runs on MacOS Tahoe 26.5, but that OS warns about the removal of the Rosetta support for running Intel code in a future release of MacOS.

My machines are M2 Ultra Mac Studio and M3 Max MacBook Pro.

Sadly there are still many P13 bugs (I push the envelope with large scenes) which will never be fixed on Apple platforms.

Thank you so much for your response to my post! I have been warned by others with Mac Pro towers and other legacy Macs to avoid Tahoe for the time being and stick with Sequoia or an older version (i.e. Monterey, Big Sur, etc.) for the time being, so that is exactly what I intend to do.
