New to forum, appreciate anyones help. you probably get a lot of these posts but some one elses opinion would be great. I bought a 2011 Macbook Pro 15" Intel Core i7 2.3Ghz 750Gb hdd, probably bought it about 2 months ago. It has started running very sluggish, and overheating and turning off. It can take up to 2 seconds to open a folder off the desktop, photoshop is very slow (it is a legit version), iphoto was so slow i actually deleted it as it was causing the machine to freeze whenever it was open. Browsing in chrome is moderately slow, firefox is shockingly slow. constant freezing, beachballing. Constantly having to force quit browsers. I have maybe 250 GBs of files on the hard drive, photos in lightroom, 80GB in itunes. It was actually hanging up and freezing before i put photos on it. I swear i had less issues with my 2007 macbook. I tried verifying disk permissions, verify disk came with no issues. Should i just take it back to the shop? i live in country NSW australia, the trip to the mac store in sydney where it came from is a good 5 hours, so not having to send it away would be preferable. Any advice?
