Error trying to use Proteus Natural on MacOS

kiprode · January 23, 2026, 4:29pm

I got an error in both the benchmark test and trying to process a movie with Proteus Natural.

Here is the log

I am using a Mac Studio M4 Max 64 GB ram running Sequoia 15.6

Same. Every time I try to run Proteus Natural, no matter which way, it leads to an error or crashing. When I try to use the Frame Preview Beta function with Proteus Natural, it crashes. Not sure if this is an issue with all versions or potentially with Macs (or Silicon processors)? Using a 2021 Macbook Pro M1 Max.

Not a general AppleSilicon issue as it works here on an M2Ultra. MacOS 26.3 Beta here.

Are you on Sequoia as well? Maybe that’s the culprit…

Although this would bring Topaz in the uncomfortable situation of not correctly supporting both, Tahoe (Starlight) AND Sequoia (Proteus natural)

Sequoia may be the culprit because using a different boot drive it works for me with Tahoe 26.1

Thanks for reporting.

So, as a Mac user you really have to choose between a - only partially - working Starlight (under Sequoia) or Proteus Natural (under Tahoe)?

Would be really embarrassing…

Proteus Natural runs on MacOS 15 Sequoia. Sent the logs to the devs as this is a new error code. Will follow up when we hear more.

I’m currently on Tahoe 26.2

I get the error on my Studio M1 Max but not my my Macbook Air M2. Both on Tahoe 26.2.

However, as a possible work-around until this is fixed: I found by accident that if the max memory in the processing settings is set to 10% it works on my M1 Max. So you might want to give that a try in the meantime - IF you’re desperate to use this model.

Unfortunately, that is not entirely correct. In Sequoia, on my M3 Ultra, the only way I can get it to export is to set the max memory to 10%. Otherwise there is an error.

However, when trying to use Proteus Natural with the Frame Preview, it crashes and quits the app regardless of the max memory setting.

Not desperate to use per say, but intrigued to see any new models and what I can potentially get out of them. I tried setting my processing settings to 10%. Still get the error, didn’t crash though. Very frustrating as I just renewed my yearly for Video AI and can’t even get a preview of this model.

Hey Andy, can you email us with a link to this thread as a reference? We may have a potential fix
