Thanks again for the report, which pool are you using? I'll give it a shot to see if I get the same messages and CPU usage. I get 0.2-2% so I'm not sure what's causing that for you. The memory issue should be fixed though :/
I'll change the way the preference works for the dock icon to avoid that problem! Seems it's not working till a pref is set right now.
The best way to run without the MacMiner GUI is the command line way in the top post, run
/Applications/MacMiner.app/Contents/Resources/bfgminer/bin/bfgminer -h
In terminal and it'll tell you how it works! You'll be able to get feedback on how it's working/accepted shares that way.
Otherwise, just check with your pool that it is still mining if you've started it with MacMiner.
Temperature and Dock speed is still not showing, New error:
