The last year I've been hard at work to update Ultra Fractal to run natively on the new Apple Silicon Macs. That was not an easy task because the internal formula compiler outputs JIT-compiled native code so it needed to be partially rewritten specially for the new ARM processors. I'm very happy to announce that it's ready for a public beta test now! If you own an Apple Silicon Mac, please download and try this version, and let me know (here or via email) about any problems.
Thanks for testing!
