I'm using external speakers on my iMac, and im plugged into the headphone jack, is this ok?


Also because im connected externally, I have my iMac volume to the top and i now control the volume externally, will this harm my mac having the volume to the highest? (the volume on the iMac, not ext. speakers)

1, No no problem, I am connected to an amp thru that jack

2. no - not a problem at all
