    As the title asks, really. Is it safer for an iMac to be shut down from a power cut whilst turned on, or whilst sleeping? We tend to get a power cut once every couple of months.

    I assume it's worse when it is on. Am I correct?

    Better to be shut off in reality...
    but you can get a uninterrupted power supply for relatively inexpensive...
    that would work nicely with your iMac.

    Then you don't need to worry about power surges/spikes, or cut offs and your iMac will just continue to sleep like a baby.

    Neither one is a good idea, but from a sleeping state should be marginally preferable. Just be sure to maintain a current backup that isn't plugged in to guard against data loss in such an event.
