Hi I have a 2.8 Ghz Intel Core i7 iMac with 20GB of Ram operating OS X 10.10.5. Just lately it has been freezing. All the applications stop, I can’t command tab from one to another, I can’t command option escape to see if any application has crashed, the only think that works is the mouse, which moves around, but cannot activate anything. - Have just restarted again after another freeze and this time the mouse was able to move the draft of this email around and that was all. I could not take it off of this email and even when the email passed behind other open windows on both screens it was always being controlled by my mouse. The mouse could not control anything else. This time I did try Command Option Escape and the window did down, but the Force Quit button even though blue and appearing active did not activate and as mentioned previously the mouse could only control the movement of the email. Again I had to press the button on the back to close down the iMac and again to restart it and now it is all working again.
The only option I have is to press the button on the back to turn the iMac off and then press it again to turn it back on. It restarts without any problems and worked fine until it happens again. I had a look in the Activity Monitor application to see if I could find anything there yesterday and again today, one thing that stuck out was under memory https://www.google.com.au <http://www.google.com.au/> was using 14.48GB and more sometimes of memory, everything else is using low to mid hundred MB’s. Under CPU https://www.google.com.au <https://www.google.com.au/> is using 101.4 %CPU. I don’t know if this is relevant, but as I only have Safari, CS5 and Mail open I am wondering why I should be having any connection to google? - Just worked out why it is trying to connect to google, I had a failed google.maps window open, (when I say failed it could not find the address I entered for it to search), so for some strange reason it redirected itself to the above address. But why? The other thing I noticed is recently I have been receiving a message, that Safari Web Content quit unexpectedly, sometimes this happens before everything freezes other times it happens in isolation. I have gone to Disk Utility and Repaired Disk Permissions apart from that I am at a loss of how to fix it. Can anyone help? Thanks Matt.
