Sorry, may be dumb question but mainly a PC guy. I searched for transfer HDD, but mostly just returned stuff about transferring files. I have a dead iMac24, won't boot, had it looked at said P/S was good so must be main bd. anyway, if I get another imac24 of similar year can I just get the old HDD swapped into the other one and be good? (or if I put the old drive in an external can I get everything on the other drive?) Thanks.
