As github is missing Mac ARM runners, this repo aims to provide a native build for darwin ARM machines. More on this can be found here: VSCodium/vscodium#597
If you get a message like this
"VSCodium.app" is damaged and can’t be opened. You should move it to the Bin.
this is because of Gatekeeper restrictions as the app isn't signed. You can execute the following to remove the quarantine attribute.
sudo xattr -r -d com.apple.quarantine /Applications/VSCodium.app
