Building NG Desktop for Mac

When trying to build an installer for NG Desktop i set the following options:
[attachment=0]NGExport.png[/attachment]

After uploading i get 2 mails, one titled Windows download is ready, which is good, and one OSX error, telling me OSX error: Command error: yarn inst-mac.

This started last week, 2 weeks ago i could build an installer, which sadly ignored my choice of icon, but that’s a topic for another post.

Is there a problem with my settings or are there general problems with the mac-client?

Good news, this seems to work right now, i got an email with the NG Desktop.
