Another user has reported the same problem you are having and from what we could discover working with them is that we can likely get Spine to work again with a bit of effort. FWIW, Spine was working when we last tested Big Sur on a dev kit. We've ordered new hardware so we can work on an M1 system firsthand. Unfortunately it may be another 2 weeks before it arrives.

Hi Nate,

Is there a progress on this bug? Downloaded the latest package onto m1 air and it fails to start.
I've attached error log below.

Not yet, sorry. The M1 hardware shipment was delayed, it should have arrived Dec 9 but we received it last week instead. We haven't made progress on it yet due to the holidays, but we'll work on it soon.

I see, thank you!

Updates @Nate?

Hello I too am having this problem (just bough a new 13 inch M1 MacBook Pro) as a daily user of spine I would greatly appreciate a fix since switching computers now would be very difficult. Love your product!!

Same issue. I tried uninstalling and reinstalling as well.

Hi all, I reinstalled and Spine is working on my Mac mini M1! I just upgraded today to macOS Big Sur 11.2.2 so not sure if that had anything to do with it (I hadn't tried in a few weeks). So excited to use this amazing program again!

Sorry for not posting an update in this thread, but we did a launcher update some time ago so Spine runs on M1 hardware.
