A:AnswerThat may be just referring to the software Seagate bundles on their drive. The drive should work with 10.4 no prob. I would just use Disk Utility to format the drive for Mac; ignore their software!! (BTW...why not upgrade to 10.6? 10.4 is ancient!)
A:Answeryes it can, but first you have to re-format unit to work correctly with OS X files, plug unit to mac and choose disk utility from apps, re-format to mac osX plus w/register, and thats all, unit will work on OSX macs.
A:AnswerI store all of that . I have backed up my entire mac including applications. I always do a scan of my computer before, for example, opening up documents and transferring everything at once. especially if it has been a while since I last backed it up. I do not want to back up malware etc. Tho I have only found a couple of files like that in ten years of checking.
