After upgrading to "macOS High Sierra 10.13" "Finder Preview" (QuickLookUIService? the space bar feature) will sometimes show a blank window when navigating with the arrow keys. I used to use this feature to verify I was uploading the correct images. Is this a known bug, and are there any workarounds?

  • Any solution to this yet? I'm experiencing the same issue... – Bokdem Nov 15 '17 at 21:58

    @Bokdem Apple said they might have it fixed for the next release, I'll be using Debian instead. – user1133275 Nov 16 '17 at 22:33
