P: Panels and filmstrip black when switching to Develop

I just upgraded to High Sierra (10.13.1). I'll post back once I see if I'm still getting the problem. The good news is the upgrade (from El Capitan) seems to have gone smoothly.

I am getting this on Lightroom Classic - have tried uninstalling and reinstalling but still, when I enter develop mode, the image blacks out as soon as you try to do anything with it. Everything else appears to carry on as though the image was there - very frustrating!

This is so true!  Been through this myself and never again - Terrible support service. 

I just switched over to LR Classic and now the black panels are back. I am a professional photographer and this is also killing my workflow. It came on gradually after a few days. I had been using the version previous to the Classic on El Capitan with the same problem that finally went away after an update. Now, it's back and  much worse!!!! NOT HAPPY ADOBE! Thinking of moving over to DXO or Capture One Pro, both of which I have purchased but just haven't gotten used to them...yet.

Me too - A real pain!

It's absolutely obnoxious. I run version 7.0.1 on El Capitan 10.11.6 and it just keeps happening over and over again and again. ARRG!!!

New problem for me with Lightroom Classic CC. Identical behavior. only solution has been to quit / restart. Happens going in and out of Develop mode. Killing my workflow after big shoots. If Adobe says Lightroom Classic CC can't run on mac 10.11+, then my choice is todrop $4,000 on a new Mac or get out of Lightroom. Need a Lightroom version that runs on El Cap.

1. OSX El Capitan 10.11.8
2. Your Lightroom version (Help>System Info...)

3.  Running on Quad Mac Pro Early 2009 that cannot run 10.12 / Sierra.

Yes it is painful but this is better than spending hours on the phone with Adobe only to given the run around and still have the same issue.

Minimizing and expanding (Hide/Show from the task bar) works for me, but it is still painful, and should be an embarrassment for Adobe. The blackout happens multiple times per hour. Since other Adobe apps, like Photoshop, do not have this problem, it is clearly an issue with Lightroom, not with Apple. El Cap is not that old. No excuses to not support it. And as others have reported, it is still happening with Sierra.

Yes this issue will not go away until Adobe repairs the issue, they told me it was there issue and are working on it. It is not your computer! Have you tried to minimize LR and than expand/ It works most of the time but not every time fo rme.
