I've been writing about some problems with Adobe Creative Cloud app and Lightroom before. 

Today I thought I should try and remove the app, and re-install it. That fucked everything up. I tried to use Creative Cloud uninstaller and then also Adobe's Cleaner Tool and remove everything. Did not work that well and while trying to install the Creative Cloud app it did not work at all. 

The positive thing was actually Adobe's customer support. I used their chat and a nice guy took control over my iMac (as I've read other people been forced to). Never a good feeling getting someone else to control your computer, but it worked out very well, both Lightroom and Photoshop are up and running again and it's all good. 

The thing is that I'm still running OS X 10.10.5 Yosemite, and the latest version of the Creative Cloud app only supports OS X 10.11 El Capitan, which it doesn't say or warn you about and since the app automatically tries to update itself = fail. My MacBook Pro came with El Capitan installed and it works flawlessly with with Lightroom/Photoshop. But I haven't upgraded to El Capitan on my iMac, since I also do music on this computer and both my DAW and my audio interface has only recently been totally fine with El Capitan, when it comes to compatabillity and bugs and shit. But I guess that I have to, since it's probably gonna be problems down the road with Adobe, but this time I'm really impressed by their customer support. Hats off.
