Since incompatible software will not open on a new imac I will be buying, would I be causing myself and the computer problems by simply transferring a clone of my PPC HD, OS 10.4.11, to the new iMac with the Setup Assistant?

 

I'm thinking it would be easier to delete the old operating system and apps that have no updates after the transfer.

 

Do all the incompatible software and system files get deposited into one folder; if not, is there an easy way to look for them?  And are there any files/folders from the PPC  that might not be in an incompatible folder that I should delete?

    You should know that you can't use Migration Assistant to restore a Mac with Mac OS X Tiger (Mac OS X 10.4) onto a Mac with OS X Lion or OS X Mountain Lion, so you have to follow other steps manually in order to restore your data to your new iMac. See "Migration from Mac OS X v10.4 Tiger to OS X Lion" > http://support.apple.com/kb/ht4889

     

    Another thing you can do is to copy the data you want to transfer to your new Mac onto an external disk, and then, connect the external disk to your new iMac and copy it to the hard drive.

     

    If you want to know if the applications you have on your PowerPC-based Mac will work with your new iMac, open Applications folder, right-click the application you want to get the information and choose "Get Info". Then, look next to "Kind".

     

    If, next to "Kind", you see "Application (Universal)" or something similar, you will be able to use that application with your new Mac. However, if you see that it's a PowerPC app, you won't be able to use the application with the new Mac

    Thanks, Mende1. 

     

    I think it would be easier to copy everything to iMac and then see if there are any problems when I try to open them.

     

    Would opening incompatible files cause problems on the iMac?  If they simply will not open, I would decide at that point to update or delete.  What I don't want to do is have files from an ancient OS that sometime in the future would cause problems on my iMac because I tried to open them with a far advanced OS---OS 10.4.11 to 10.8.2.

     

    That's my primary concern: am I going to cause myself future problems by trying to open incompatible files?

    Incompatible files, if they are PowerPC ones, won't do anything to your Mac because Mac OS X will refuse to open them. However, if you try to open an old Intel application that may not be compatible, you may get kernel panics... I think you should try to migrate your data

    You probably can move "files" over, such .doc, .jpeg and many others over to your new Mac. That should be fine.

     

    But I wouldn't move a single app or anything like that over. Yes, as mende1 said, there are many Universal apps that will run, but you probably didn't update them to keep them running on Tiger. I just can't imagine that there is a Tiger app that you will want to keep, since things written now are just optimized for a much more advanced OSX.

     

    More than that, you'll be spending loads of time finding preference files that you'll want to keep and other things.

     

    Really, spend your time finding modern versions of apps, even if you've invested a lot of money in some ancient version of Photoshop or something.

    See Pondini's Setup New Mac guide. AFAICT, there's no conflict caused by attempting to run PPC apps in Lion/ML. Software related KPs usually occur from conflicting kext files.

    Thanks OM, sounds like good advice.

  • Paul Elson Level 1 Level 1 (25 points)

    Thanks for the link, baltwo. It seems the best route would be to only transfer files and folders that I think will be compatible even though you think there wouldn't be any problems----it's that "AFAICT" that gives me pause...

  • baltwo Level 9 Level 9 (62,210 points)

    If it was me, I'd migrate everything, using the first boot Setup Assistant. Then, remove anything that won't work (PPC apps). The AFAICT is based on beta-testing every cat from Jaguar on up to ML, so take it for what it's worth. Good luck. The new machines aren't in my future, since I have no use for iOS stuff and still use PPC apps.

    Thanks again, baltwo.  I'll try migrating everything with the Setup Assistant.  Does it make any difference, time or other factors,  if I use an external FW drive or the internal HD?

  • baltwo Level 9 Level 9 (62,210 points)

    In my testing, either should do the job, although it's easier from an ext HD.
