I have GRASS7 folder path set to /Applications/GRASS-7.0.app/Contents/MacOS
and I can see GRASS7 algs list in processing toolbox.
The only problem is that the execution of any algorithm does not generate
any output. No error is prompted.

Also, I just saw this issue https://issues.qgis.org/issues/17555 but I
cannot confirm it on my machine.
