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.
