Some UPS's don't work at all with the new iMac showing that there is indeed a compatibility issue all to do with the active PFC supply.
For those that have been lucky to pick the most pure sine waved UPS that can enable the iMac 1.to power up 2.and run smoothly without a buzz ...can they please contribute to this thread with the model, brand and part number so that new buyers like me can utilize to shop with precision using a wider pool of shopping list. APC being more preferred because of the inbuilt shutdown software and USB interface. Thanks
