This has been seen by many, me included.

This has also affected the Boundless Desktop install, which includes QGIS 2.14 LTR.

Try this (may not be the root of issue for Kyngchaos QGIS 2.18):

• Quit QGIS, if running
• Rename PyQt4.phonon module...
  

    cd /Applications/QGIS.app/Contents/Resources/python/PyQt4
    sudo mv phonon.so phonon_off.so
    # or
    sudo mv phonon.so ~/Desktop/
    

• Launch QGIS

Apparently phonon.so (it's .framework actually), built on an earlier macOS, is totally borked when loaded on macOS 10.12.4.

Tried this for my situation -> unfortunately didn't solve...

Hi Gareth. Thanks for testing that out.

I was not able to replicate the error you are seeing with a clean macOS 10.12.4 VM and the latest install from Kyngchaos.com.

Hi Larry,

I tried reinstalling a few times but don't seem to have any luck. Is there a way to forcibly remove some or another underlying components that may be causing the issues?

Thanks.

I got similar problems after updating to 10.12.4
QGIS 2.16 and 2.18 cannot open any project with vector layers. Vector layers can only be added if at least one raster layer is added. Raster layer projects can be opened.
QGIS 2.14 can open projects with vector layers. If trying to open the vector layer property UI, QGIS hangs and silently crashes after approx a few minutes, consumes a lot of system resources when hanging.
Crash logs are created - I cannot see anything obvious in them (not a true developer, though).
Vector labelling UI can be opened and used, as well as raster layer property UI.
I tried the phonon.so workaround, no change in behaviour.
Other tested tools do work, like creating polygons from closed lines.

I had the same issue on several Mac installations. In the end I did a clean install and manually removed all the plugins except MetaSearch and mmqgis from 'Users/.../.qgis2/python/plugins' to get everything working again.

I ended up uninstalling and reinstalling via brew:

brew cask install qgis

This did the trick for me however I noticed today that it broke again, and it seems as if it may have been linked to an Xcode update to version 8.3.2

I tried uninstalling and reinstalling via brew cask and that in and of itself did not fix it, however, what did fix it was manually linking to the correct matplotlib per the brew cask installation instructions:

"qgis requires matplotlib in a specific location. Please run the following to finish install:"

sudo ln -s /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python /Library/Python/2.7/site-packages/matplotlib-override
