Question

Since loading Lion, I've experienced much more instability than Snow Leopard. In particular, Mail crashes with regularity, full-screen apps seem to run slower and show the beach ball more often for longer, etc. I love the features, but I'm disappointed with the performance. Any help coming from Apple?  I've been sending them so many reports after crashes, that their file must be full!

Answer 1

Summoning max. courage, I did what you advised. Here is the result. What does this tell you? My Lion 7.2 (mid 2011 iMac) has several annoying glitches (which I have so far tolerated through gritted teeth) but none that have actually stopped me working.
BTW, I see several items involving CleanMyMac which I did not know I had. It is generally villified as a trouble-maker. Spotlight can't find an app. or a utility of that name. How can I get rid of what's there please? Just delete?
