HI...new to this forum and a new mac user...been a windows guy forever..i bought a new 27" imac a few weeks ago from best buy..then the retinas were released and I had one day to return it to best buy or my 30 days was over...whew!! returned it and ordered a new retina...i made a time machine backup of my imac before i returned it...i had upgraded to yosemite before the back up if that matters....when my new retina arrives (still shows order processing on apple store) can i just restore the time machine backup and be good to go? I did spend a few weeks customizing my first mac with bookmarks, files, mail etc etc...would love to at least be "back where i left off!!"
