Atom Helper, Mac, hogging all CPU!



I LOVE this editor however I’m noticing performance issues and opening up Activity Monitor I notice Atom Helper using 101.5% of the CPU.
I am at the latest version 1.3.2
Please help!




Here is some quite relevant discussion about this issue. It is a long thread:


Thanks for the link!
The title link give me a 404 however works.
I am also on a MacBook pro - I edited the same file on my iMac last week with no issues.


There’s all kinds of things that can cause this issue. Have you tried running Atom in Safe Mode?

To launch Safe Mode:

  1. Completely exit all instances of Atom
  2. Launch Atom with the command atom --safe

Have you followed the suggestions in the Debugging document? Also, could you give the following information?

  • Which version of Atom are you using?
  • What OS and version are you running?
  • Do you have Emmet installed?


Hi Leedholm.

Sorry to take so long to reply to this post.

I found that what finally worked was from a long thread on the topic directing to “Force quit Atom Helper through the Activity Monitor, then quitting Atom, then starting back up again”. This resolved the issue for a goo long period of time. It’s rare, but it will occasionally happen again, so I just go through the process.

To answer your questions, Atom version 1.4.3, Mac OSX 10.11.3, I do have Emmet installed.

The Safe mode option didn’t work, the helper still hogged everything up.

Thank you!
