PCLinuxOS - KDE, works just fine on my IMac, no problems so far.
CPU is normal and the temperature also, it is the best for my Mac, and still working.
AND, its not dual boot or boot-camp, ONLY PCLOS !
And i have tried more than 4 other distro's who say's... That they are the best for those machines. Well PCLinuxOS team, You can be proud of the work !
Now i had to work, helping my daughter in her new house, fathers...
