    My new 27" iMac gets occasionally very slow and according to core activity monitor bars only the "left bar" shows some (very high) activity.

    After a reboot both cores work just fine (again according to those bars) and the computer works normally.

    This makes me wonder if this is pretty much the same problem that the first generation MacBook Airs had :eek:
