I've been using Atom for years on my Mac. I know it has been end-of-lifed by its dev team. I haven't installed anything new on it like plugins for many months. After the latest MacOS update, I get this popup when trying to open it:
Does anyone know if there is a way to tell if my copy has somehow become corrupted, or if this is a false positive?
Many thanks!
OK I found out that github revoked the Apple code signing certificate and is now enforcing that. I found the answer on the Atom blog. So, I was able to download an older version and it works well.
