Lightroom doesn't work on any of my Macbooks after updating to Mojave. After noticing I had this program on each of my macs with Mojave I created a installer to go back to High Sierra. I rebooted my Mac and after 6 hours I was able to go back to High Sierra on all my macs. Lightroom still doesn't work. Im not sure now if this is lightroom, if this is Mac or what else could be the problem???
