I upgraded to MacOS High Sierra and am running 10.13.1. After the upgrade, I went into LR and it was constantly quitting on the launch. I searched the internet and I found solutions like changing permissions to Read & Write (which I did) but that didn't solve it. I then ended up uninstalling LR and reinstalling it with my original disk. After I installed it with my disk I went to Adobe's website to upgrade to the most recent version of 5.7.1. I changed those permissions to Read & Write and I had a couple of reboots in there. Now when I try to launch, I'm getting error 213:10.
Obviously, this is super frustrating. Can anyone help?
There are problems running Lightroom version 5 under High Sierra
You might want to roll back your operating system to Sierra.
Or upgrade (purchase) Lightroom to Lightroom Classic CC or Lightroom 6.14.
Adobe does not support Lightroom 5 any more.
