Got a few problems with my iMac that are driving me a little bit mad. 1st problem is to do with my emails. For some reason I can't view them on my iMac. If I open my mail on mac no emails come in, but open mail on my iphone and I get loads of emails coming through. I used to get emails on both mac and iphone, but now don't. Is there something I need to do to sync them or something? 2nd problem is my mac is running very very slow, to the point where I want to smash it up!!! I use it for web browsing mainly, don't have loads of apps on it, don't have loads of photos or videos, never use it for watching porn, just casual browsing mainly, but for some reason it's been running slow for weeks now and most pages don't even fully load either. I'm seeing the spinning beach balll of death a lot as well. Is there something I need to do to speed my machine up? (like defregment on a windows pc) The problem isnt just when surfing the internet, when I tried to open up my system preferences panel, it took about 9 or 10 seconds to open up (compared to about 2 months ago when it would have opened up almost instantly ) Thats why I'm wondering if it some sort of defrag that needs doing??? Any help appreciated, before I launch 27 inches out beauty straight out the window!
