"Atom cannot be opened because of a problem" on Mac


I’ve been using Atom on my Mac (running Yosemite 10.10.5) for a while now but for some unknown reason when I tried to launch it this morning from the Applications folder I got an error message and it wouldn’t open.

I’ve tried re-installing it from https://atom.io/ (v1.28.0), and also tried opening from the Terminal using open /Applications/Atom.app but the same error persists. When I try opening from the Terminal I get another error: LSOpenURLsWithRole() failed with error -10810 for the file /Applications/Atom.app.

Oh and the same thing happens even when I install Atom Beta, which I’ve never had installed before now. I know when you remove Atom from the Applications folder your settings/packages remain behind (presumably in Application Support or somewhere like that), but I didn’t want to have to do a complete wipe of the installation because it would mean losing all of my settings and installed packages.

Any help would be greatly appreciated.


You can try earlier versions of Atom. It seems 1.28.0 has had issues with older Mac versions for a few people.


Thanks, I tried rolling back to v1.21.2 - not ideal but the main thing is it works now and I haven’t lost all of my settings!


Hello! may I ask how to download the earlier version please? I tried to search it online but didnt quite find it! Many thanks!!!


I downloaded one of the versions from here.

I also tried v1.27.2 from here here, which worked.


Pretty sure folks are hitting this issue (if you’re on macOS 10.10.x or lower and the crash happens with Atom 1.28 but not 1.27.2):

We suggest installing 1.27.2 and turning off auto-updating for now /cc Atom won't start all of a sudden and you can subscribe to https://github.com/atom/atom/issues/17565 for updates.

Previous Atom releases are available here:

E.g. https://github.com/atom/atom/releases/tag/v1.27.2

Going to go ahead and close as a duplicate for now.
