Understanding permission in new macOS instances

[ericoporto]

Hi,

So, I am experimenting the new macOS images, it took me a bit to figure it out what to actually write in the yaml file to get it to switch from Intel to Apple Silicon,to get it running again.

But now I have an error I am not sure what it means

I am trying to get Ninja in /usr/local/bin/ninja so I can run it, but I get a permission denied error when trying to copy it. This used to work in the Intel images, is there something I need to do?

Additional question, does the Apple Silicon used by Cirrus comes with the feature to run Intel-64 binaries too?

Hey @ericoporto,

My guess is that System Integrity Protection in newer versions of macOS restricted more things like touching /usr/local/bin without sudo. I'd suggest to try to sudo cp insted.

Also if you have an Apple Silicone machine at your hands, you can try to play around with the VMs locally using our virtualization solution called Tart: https://github.com/cirruslabs/tart

Thank you! I didn't knew it was an OS change, thought something was different in the image making process.
