Nuclear fusion on my Mac


I downloaded the package, after extracting, and double clicking on it, I get an error. Attempts to run it from the command-line resulted in

  • a segmentation fault when running without sudo
  • silent failure when running with sudo

Any ideas as to what might be wrong? My Macbook is quite old.

MacBook Pro Mid 2009, 2.26 Ghz Core 2 Duo, OSX 10.7.5


Atom requires Mac OS X 10.8 or above, we recently added that information to the download page.

Crash on launch OSX 10.7.5

Can you add a LSMinimumSystemVersion to the app’s plist to avoid these errors?


Will do, thanks for the tip!


+1 is possible to fix it without re-download/re-compilate ? I’m on:

And I can’t update.


Sorry, 10.8 is required, are you saying you’ve upgraded to 10.8 and are trying to download again?


When I downloaded it the osx version wasn’t specified (if i remember well).
I read about .plist editing to fix… but maybe it was referred to the crash and not to have a working version on 10.7.5

I could migrate to osx 10.9 but I don’t see any new useful feature but only performance issues and other problems.

Will osx 10.7.5 be supported in future?
