Unable to start Atom: “dyld: Symbol not found: _CIDetectorTypeText”



Atom 1.28.0 fails to start on OSX 10.10.1

Steps to Reproduce

  1. Start Atom as usual from the Applications folder, Spotlight, or the command line

Expected behavior: [What you expect to happen]

App to launch as usual

Actual behavior: [What actually happens]

  • When started from Finder/Spotlight, a popup window appears which states Atom cannot be opened because of a problem.

  • When started from the command line with /Applications/Atom.app/Contents/MacOS/Atom, the error text is:

dyld: Symbol not found: _CIDetectorTypeText
  Referenced from: /Applications/Atom.app/Contents/MacOS/../Frameworks/Electron Framework.framework/Electron Framework
  Expected in: /System/Library/Frameworks/QuartzCore.framework/Versions/A/QuartzCore
 in /Applications/Atom.app/Contents/MacOS/../Frameworks/Electron Framework.framework/Electron Framework
Trace/BPT trap: 5
  • When started with atom --safe, the error text is
LSOpenURLsWithRole() failed for the application /Applications/Atom.app with error -10810.

Reproduces how often: [What percentage of the time does it reproduce?]

100%% of the time; unable to start Atom normally


The Atom version commands are not working. They cause the “Atom cannot be opened because of a problem” popup to appear.

I downloaded the latest version of Atom (1.28.0) and replaced my previous installation with it, but the result was the same.

OSX Yosemite 10.10.1

Additional Information

  • I have tried re-downloading Atom and reinstalling it, which made no difference to the error

  • I have tried removing ~/.atom, which made no difference

  • I have tried restarting my system several times

  • The issue seems to have started after two instances of the program opened following a system restart, but both hung and had to be force quit. Googling the specific dyld error message I receive in the console yields no relevant results.

  1. Same here on OSX 10.10.5, except I don’t see a popup – Atom 1.28.0 just silently fails to open.

    Downgrading to Atom 1.27.2 solved it for me.

  2. Worked for me as well, but there is a gotcha: if you have autoupdates enabled it’ll only start once. So essentially what you have to do is to

    1/ download Atom 1.27.2
    2/ unzip it
    3/ launch it
    4/ disable auto updating
    5/ delete the previously extracted Atom executable
    6/ unzip it again and move it to /Applications

  3. Running on MacOSX 10.10.5:

    Atom 1.28.0-beta0 works
    Atom 1.28.0-beta1 works
    Atom 1.28.0-beta2 works
    Atom 1.28.0-beta3 works
    Atom 1.28.0 crashes

  4. This issue is resolved in #17620, and we’re actively working on publishing this fix as part of Atom 1.28.1 and Atom 1.29.0-beta1.

    Once those releases are published, Atom should once again run on OS X 10.10.x. 💦

  5. Atom 1.28.1 and Atom 1.29.0-beta1 are now available and should resolve this issue for anyone using Atom on OS X 10.10 Yosemite. Additionally, if you’re seeing this issue on OS X 10.11 El Capitan or macOS 10.12 Sierra, please give this update a try and let us know if you continue to experience the problem.
