Each time it crashes, i.e. hangs and then drops to the log-in screen (note I have automatic log-in set, so normally don't need see this screen) these three programs produce a crash report 1) Windowserver 2) Kernel 3) AdobeCRDaemon, sometimes also cloudphotosd, DesktopServicesHelper and Disk Utility. Have been unable to figure out which one instigates the crash though? Spent over an hour going through it all with Apple support. As I had not installed any new software, the suggestion is that an update came through and there was a incompatibility? So set up a Test log-in with no Apps running i.e. ensured everything was turned off in Users and Groups/Log-in items - but still got crashes! Booted to safe mode, didn't get any crashes! So, making a guess that is was Adobe? I re-booted to normal mode and checked Creative Cloud. Found that the Menu Bar App needed updating as did PhotoshopCC, LightroomCC and BridgeCC. Since then no crashes and the iMac seems to be running without bogging down. Was it simply the booting into Safe Mode that sorted it out or was it the updating Adobe, perhaps the Menu Bar App? Have set the Diagnostics and Usage to send reports to Apple. I see that the reports were submitted to Apple this morning which triggered a diagnostics messages cleanup. I hope that Apple will be able to look at them in detail and define the reasons for the crashes. I am not sure we are totally out of the woods though as the iMac is still down on performance? Will monitor Console closely over the next couple of days.
