It is a late 2009 iMac 27 inch Processor 3.06 GHz Intel Core 2 Duo Memory 6 GB 1067 MHz DDR3 Graphics ATI Radeon HD 4670 256 MB Software Mac OS X Lion 10.7.4 (11E53 I have 274 gigs of the the terabyte SATA Disk free. My iMac has been running incredibly slow lately. To open up anything, seems like it is overworking it. It takes about 30 seconds to open up an app. Photoshop and iMovie have become basically unusable because the computer is lagging so much. The internet runs 75% slower than it did three months ago. Youtube videos often pause or won't stream at all. I need to restart the computer about five times a day, just to surf the net. It has even frozen up a few times, which I didn't know Macs would even do. (That was the whole reason I switched to Mac in the first place.) What should I do? Should I just take it in to get fixed?
