I have a 15" 2.53 GhZ Macbook pro with 4 GB Ram. I am using Onyx for cleaning disk permissions as well as flushing the cache and other maintenence becasue I heard great things about it. The most recent time that I used it I Restarted my macbook and the mouse was frozen and I couldn't move it, even after like 5 minutes. So I did a hard restart and everything started up just fine. Has this happened to anybody? Is this a sign of the macbook maybe on its way out? I've only had it for a year and a half and I bought it brand new. I'm probably just paranoid and overreacting.
