I was going to post in the already present OS X miner thread, but realized i'm tagged as a newb...

Basically I wanted to confirm what robin1979 (http://forum.bitcoin.org/index.php?topic=12360.msg219345#msg219345) had found, that Mac OS X Lion (10.7) does indeed speed up mining for OS X users.

My Mac Pro with ATI Radeon HD 5770 in 10.6.7: ~103 MHash/s
My Mac Pro with ATI Radeon HD 5770 in 10.7 DP4: ~153 MHash/s

Note that in 10.6.7 I was using poclbm (-w 256 .... -v caused a massive slow down on this card). In 10.7 DP4, I was having issues getting it to compile and build (weird make errors, and haven't spent any time researching). So under 10.7, I was using Diablo. I know...not a perfect comparison, but at least us OS X users have something to look forward to in a month or so!
There are several different types of Bitcoin clients. Header-only clients like MultiBit trust that the majority of mining power is honest for the purposes of enforcing network rules such as the 21 million BTC limit. Full clients do not trust miners in this way.

It's too bad that Apple doesn't ship their systems with better video cards. That would make an even bigger difference.
