Magic/Mojo on MacOS 12 not supported?

Just starting to play around with Mojo. Following the instructions in the docs on MacOS 12 on an M1 macbook I am getting this error on running magic shell about MacOS 13 being required. I can't find any docs suggesting MacOS 12 is not supported. Googling that error, I can't find anything relevant. So before I go to the trouble of updating the OS I thought I'd ask whether anyone else has experienced this.

$ magic shell
  × The current system has a mismatching virtual package. The project requires '__osx' to be at least version '13.0' but the system has version '12.4'

When you say the docs. Are you referring to the getting-started ? When you magic --version are you getting 0.3.1 ? There was an issue - and I'm wondering if it's related - about magic, SSL certificates, mac0S, and the way some upstream developers were doing things. The fix for that was to revert the magic version command . I tried searching Discord for the details but got a bunch of noisy results. You can try to version 0.3.0 and see if that works. Also, there's an issue template for magic in the mojo repo

@tohmly can you share what prints when you run magic info?

Yes, I am following the getting-started guide.

Are you following this doc? https://docs.modular.com/magic/ (there's also this one, so want to make sure I'm following along via the right doc)

I just tried initialising a simpler project with magic init my-project (i.e. without --format mojoproject ) and the error is the same I get the same error on magic versions 0.3.0 and 0.2.3 (initialising a new project each time)

Caroline•7d ago

sorry just seeing this now! will get back to you shortly okay so adding the following to your mojoproject.toml file should resolve the error:

# Default system requirements for macOS

[system-requirements]

macos = "12.0"

# Default system requirements for macOS

[system-requirements]

macos = "12.0"

(Magic is built on Pixi, which has a default requirement of 13.0, so that's why this error is happening - but adding the above should fix it)

That did the trick - Thanks for the help!
