Apps constantly crashing: failed HDD?
Hi everyone. I own a late 2009 unibody mbp with 2gb ram and a 160gb hdd. The OS X I am running is 10.11.1.
Recently, all of my apps apart from safari constantly crash and not respond. It's a major issue now, sometimes even finder won't load. I have 2011 copy of microsoft word and this will now not load any documents, and just goes to "not responding" when I right click on it and I have to force quit it. I have tried to repair disk permissions but cannot do it with the disk utility on 10.11.1.
Does anyone have any idea what's going on? I'm thinking that the HDD may need changing?
Thanks in advance.
MacBook Pro, OS X El Capitan (10.11.1)
