Hi everyone, Since I upgrade my Imac for Yosemite 10.10.3, the machine is really slow to shut down. It needs 5 minutes and I've got the wheel during this time. I did a lot of researches for this issues and I did some unsuccessful action : - I upgrade it for 10.10.4 - I reset the PRAM, repair the disk & the permissions - I use Onyx with no success - I choose my hard drive as starting disk in the preference panel - I do a clean delete of parallels tools (I use vmware but I've got some parallels files) Anyone has an Idea ? I'm pretty stuck with this issue and it started to p*** me off. Thank you for your help.
