Hello, Just following-up on whether or not killing the ccxprocess in activity monitor worked for you. I have killed that process and all Creative Cloud processes on my Mac and I still cannot get the Secutity Update 2005 005 10-13-6 to install on my system. When I try and shutdown or reboot I get an arrow in the middle of the screen, that moves to the upper left on a black screen then just hangs. I let it run all night and it never fixes itself. If I tell the update to install overnight, it stays up but says the install and restart "ccxprocess prevented installing this update from being installed". I booted into safe mode, I reinstalled the OS but still cannot reboot the mac or install the security update. I was wondering if it worked for you when you force quit ccxprocess through activity monitor.
