Running into an odd issue when my system starts up: python failure

I have not been able to track the point of failure down yet. I assume that it is some application that is attempting to start at system startup, but I have not yet been able to isolate the application or daemon. The actual problem report seems to be quite unhelpful in this case:

I thought that perhaps it was an issue with Homebrew's python installation, but after removing and re-adding it, this does not appear to be the case.

Any thoughts?

  • What does /usr/bin/python do? – Mark Sep 18 '15 at 21:40
  • @Mark /usr/bin/python --version: Python 2.7.10 – ylluminate Sep 19 '15 at 2:37
  • What's the output of which python? – Kellen Sep 19 '15 at 13:48
  • @Kellen /usr/local/bin/python and /usr/bin/python – ylluminate Sep 19 '15 at 13:50
  • I don't use OSX, but on other Unixes I'd use starce/truss to see what's going on. I believe the equivalent on OSX is dtruss - so from the OSX shell run dtruss python and you may get a hint as to your problem. – boardrider Sep 19 '15 at 19:30

Was fighting with this issue today, after I upgraded python using brew, the annoying pop up wouldn't let me work on my Mac! The only difference is that it was shouting for python3.4. After couple hours of digging I just decided to:

  • remove all python3 whatsoever, the one installed by brew and the one installed manually from dmg.

  • search for all remaining symlinks to python I've had on my development projects folder. After deactivating all the venv's and removing the symlinks the pop up was gone.

Then I found this post of jeremycade which explains the less aggressive approach.
