I just got 27" iMac 2.7GHz Quad-Core Intel Core i5, 12GB 1333MHz DDR3 SDRAM, 1TB Serial ATA HD, 256GB Secondary SSD, AMD RadeonHD 6770M 512MB GDDR5, OSX Lion, Thunderbolt... I used Migration Assistant to transfer files from a Lenovo ThinkPad to the new iMac. I discovered that all the files are under the original PC account name, different name than the new Mac. In researching how to "combine" the 2 accounts, I started to read where maybe it's not a good idea in the frist place to use MA when transitioning from a PC to Mac. So my question is: will Time Machine reverse the migration? Or is there a better way to proceed? TIA, I really appreciate everyone sharing their expertise here.
