Lately PICO8 will sometimes randomly crash, sometimes in a running game, sometimes in the editors. Full error in terminal shows up as:
-[MTLRenderPipelineDescriptorInternal validateWithDevice:]:2400: failed assertion `No valid pixelFormats set.' |
I am running High Sierra (10.13.6) on a 2013 iMac.
Thanks for the report @Hoatzin
How often are the crashes, roughly? If they only started recently, my best guess so far is that something in a OSX security patch has broken SDL's video driver.
A temporary work-around in this case would be to use a software blitter instead by launching from Terminal with:
PICO-8.app/Contents/MacOS/pico8 -software_blit 1 |
(from the same folder that the application is in)
I'd be interested to know if this does indeed stop the crashes from happening. The software blitter uses a bit more cpu that the default but otherwise should work the same.
Nope still failing. I opened a free-running demo and let it sit and it eventually failed, then I restarted and it crashed immediately.

Around a year ago (~Nov 2019) I had demos of my students' games running in a Mac-powered arcade cabinet in a gallery setting around the clock for weeks with no crashes (afaik). I'm a little hazy about the deets as I usually run these kinds of public installations in an infinite bash relaunch loop so it gets its biz together on crash automatically... but all the same, I don't recall crashes being an issue, and ditto while we (couple dozen kids) were actually working on the project in the lab most of that autumn (tho it could be we didn't have the most bleeding edge PICO-8 installed on the lab computers)... Seems likely that whatever introduced the bug has happened since.

FYI: 0.2.2 crashed ten minutes after starting it (w/ software_blit) first time. Most of the time it reports Abort trap: 6, but sometimes it says Segmentation fault: 11 and doesn't print any other error info. Might be a different thing.
Hi @zep,
I'm also seeing the same crashes as @Hoatzin, happening every few hours: -[MTLRenderPipelineDescriptorInternal validateWithDevice:]:1877: failed assertionNo valid pixelFormats set.
Running: Pico-8 0.2.3 on macOS 10.12.6 (Mac mini, late 2014).
Here's the stacktrace of the crashed thread from the various crash reports (callstack is always the same):

I also built the current version (2.0.17) of the SDL framework w/ debug symbols, and copied it over the version in the Pico-8 app; Still crashes every few hours, but now it shows the SDL function names in the stacktraces (assuming it's the same issue):
