A friend's G5 iMac (rev B, the one right before the first ones with the iSight Camera) is showing signs of imminent death -- lots of beach balls, sporadic unexpected shutting down. She bought a new MBP on Friday and on Friday evening we tried to use Migration Assistant to transfer her settings, files and folders over to the new MBP. The iMac shut down in the middle of the process. She tried again today and the same thing happened. I had suggested right from the very beginning that she use an external drive to copy her iTunes folder and her iPhotos folder and anything else she wants and then she would be able to transfer everything right into the new MBP. The advantages I can see here are that then she's not transferring any nasties from the PPC machine and is just transferring only her folders. A concern I have, though, is that the iMac might shut down in the middle of copying the folders, with the possibility that this could corrupt the files and corrupt the external disk. She wants to try running Migration Assistant one more time tomorrow or to try transferring the stuff from the iMac to an external drive. My questions: (1) Are my concerns about corruption and potential loss of folders/files and corruption of the actual external HD valid? (2) How do we go about transferring her iPhoto '08 and iTunes folders from the iMac to the external drive and then from the external drive to the MBP? I don't use iPhoto myself and while i do use iTunes I have to admit I'm not all that savvy with it and have a pretty small iTunes library compared to most people, including my friend. (3) Is it possible to transfer everything by using Target Disk Mode? Hooking both machines to each other and instead of using Migration Assistant simply transferring the folders that way instead of using an external drive? My understanding of Target Disk Mode (which I've never used) is that it makes the one machine like an external drive mounted on the other machine. (4) My friend does have Time Machine on the iMac and has been using it for the last several months so she does have a backup available that way. I have not used Time Machine and am not quite familiar with it and what it will/won't do, so I'm not sure if we can simply use that somehow on the new machine. The fact that we're dealing with a G5 PPC and an intel Penryn makes it a little more complicated than if it were two intel machines. The fact that the iMac is definitely moribund and abruptly shuts off without warning right in the middle of doing things adds to the complications. Both machines are running Leopard. Both have iLife '08. I'm a little leery of putting the backup from a PPC machine into a brand-new intel machine. (5) Should we say forget it and take both machines to the local Apple store and let them deal with it? She called them today and they told her that it would cost $150 and that they wouldn't be able to do it for her because she's not a ProCare member but that they could "walk us through it." Um....the day she bought the MBP they told us that the Apple store offers the free service of doing the migration and setup from old machine to new machine.... So now they're saying $150??? Definitely I would appreciate some guidance and assistance as to the best way to approach this problem. Both my friend and I are afraid that the iMac will take its last breath and shut down forever before she can rescue her valuable files and get them into the new machine.
