Hi there, I have a early 2011 13" macbook pro i5/4GB/SSD and am experiencing this constant hanging/freezing/beachball issue occurring multiple times a day whilst running anything from just firefox/chrome (most frequently, but this is also the most frequently used application) to heavier applications to installing applications from DVD & running VLC. The only pre-occurrence noticed was whilst running Chrome - all the windows usually load up the "aw snap" page. Otherwise the mac begins to beachball, the macbook heats up and fans go full throttle for a bit, then it comes back to temperature and continues to do nothing at all until you reboot it. I have run disk utility multiple times - the first time it found something, every time since nothing. Memtest shows up fine. Apple hardware test shows up fine. As a last resort I have attempted a 'windows' solution by doing a clean install which doesnt seem to have helped either! Would appreciate any suggestions Edit: Resolved by having the SSD replaced.
