Whenever I select a package.xml in the Module Settings to set my metadata subscription to a manually predefined subscription, after confirming the open file dialog the file has not been selected (see "Screen Shot 2018-01-09 at 16.02.44.png").
If I confirm the dialog, Illuminated Cloud will complain about a misconfiguration, see "Screen Shot 2018-01-09 at 16.01.51.png".
I did not find any way on how to set the subscription model to my package.xml. As a workaround I manually selected the components I want to retrieve or sync.
This issue only occurs under Mac OS X High Sierra 10.13.2 and is reproducible on other computers with Mac OS. Another computer with Windows 10 does not show this issue.
idea.log does not list any entry during configuration edit.
