Well, I really like this piece of (shit) software and I use it together with Photoshop (both of them are the CC versions) for every single photo I take. I do all the major work in Lightroom too, with just a couple of minor things in Photoshop. And it's usually a very awesome software to work with. Usually...
Though after updating to Lightroom 2015.5 (or 6.5 if you don't use the CC versions, they both have the same problem) the other day it and first launching it today, it had stopped working, after being solid as a rock on my iMac (like anything else when it comes to this machine) since I got the iMac in May 2015.
But today (after spending a day in Copenhagen) it pissed me off so bad, since it simply did not launch. And due to some things in this update not working correctly with OS X (don't think Windows users have had any problems) it has made a lot of people irritated and stranded with a photos not being able to get processed.
But now finally, after a few kinda angry hours of not being able to even launch Lightroom I found a fix. Still it's very annoying and Adobe has to fix this in a proper way, with a full new update, taking care of this and it has to be soon. Stuff like this is not acceptable.
Here's a link to the thread that helped me.
