:florian, the convert and compare issues might be caused by missing libMagickWand*.6.dylib in /usr/local/lib. You can find the binary in the ImageMagick bin folder.

For me I had to run the following command to get it to work:
```
ln -s /Users/gregorymierzwinski/.mozbuild/browsertime/ImageMagick-7.0.8/lib/libMagickWand-7.Q16HDRI.6.dylib /usr/local/lib/libMagickWand-7.Q16HDRI.6.dylib
```

```
EDIT: I noticed that it's failing the checks when called through `./mach browsertime --setup` but it's passing when calling the visual-metrics.py --check directly with: 
```
/Users/gregorymierzwinski/mozilla-source/mozilla-central/obj-ff-dbg/_virtualenvs/init/bin/python /Users/gregorymierzwinski/mozilla-source/mozilla-central/tools/browsertime/node_modules/browsertime/vendor/visualmetrics.py --check
```

EDIT 2: Actually, it's possible you have the wrong ImageMagick version (it should be 18.7) and unpack_file is breaking. That's what seems to be happening for me.
