Describe the issue:

Perhaps not a Positron issue, but a MacOS issue with workaround:

Steps to reproduce the issue:

1. Download the dmg from the website or GitHub Releases

2. Install the dmg

3. Post-install MacOS will verify Positron and says

   “Positron” is damaged and can’t be opened. You should move it to the Trash.

   with two buttons below: "Cancel" or "Move to Trash". Clicking "Cancel" will show the same error again, until you click "Move to Trash" which will uninstall Positron.

Expected or desired behavior:

1. Installing the dmg should just work

Workaround

Instead of clicking any button, go to the terminal and execute (see https://discussions.apple.com/thread/253714860?sortBy=rank)

xattr -c /Applications/Positron.app

then click "Cancel" and opening Positron should work!

Perhaps this can be added to the README/documentation somewhere?

No source file or test is named. Start by reproducing the failure with the linked DMG and inspect the macOS release and installation path; compare the downloaded artifact with the reported xattr workaround. Done means Positron opens after installation without that workaround, or the workaround is added to the README/documentation.
