Is anyone else unable to open Atom Stable or Beta or Nightly on Catalina at all? Don’t see a single mention here or on twitter so wondering if just me?
I am also having the same problem. I realize that it’s the same problem with chrome.
Downgraded to Mojave and same issue. Figured out the issue was corrupt settings. Deleting the .atom hidden folder in my home folder resolved the issue so looks like it wasn’t a Catalina issue. That is the folder seems to have got corrupted when upgrading to Catalina but had I deleted the.atom folder on Catalina pretty sure would have fixed the issue there too.
Deleting the .atom directory did not help.
I the only think that helps is restart and start it as a first app.
Catalina disabled the x86 app support so maybe its the issue.
Atom has been exclusively a 64-bit application on macOS for years. So unless you’re using a tragically old version, that isn’t the problem.
I’m running Atom Nightly v1.42.0-nightly8 on macOS 10.15 right now and it’s working fine.
I also had this issue. Seemed that some of my development packages couldn’t be found. I fixed this by re-installing command line tools… running “xcode-select --install” in terminal. Then reinstalled Atom with Homebrew. All seems good now. Hope this helps
