I need to run a few programs in OS 9. Can I still run them if I upgrade my G4 powerbook to Leopard?


Power Mac G4 (Gigabit), Mac OS X (10.5)

    If you ran them in Classic, no. If you ran them in Mac OS 9 as a native OS, yes.

    Thank you for responding. I originally ran them under OS 9; but then upgraded my powerbook g4 to Tiger; so have been using Imageready 1.0 and a Tarot program under classic. I tried to follow the discussion before leopord was released; but am a simple user; so it probably went over my head. Is the 2 partition option still possible now that leopard is released and known not to support classic? I have a seagate drive to use for back ups; but don't know if I can boot from it. I haven't found any updates to these programs, and do use them regularly. Thanks for any suggestions. The only reason I would update my OS is Turbotax. This year we need Leopard to run it. I love my G4 and really can't afford a new computer. Thanks again

    Mac OS X 10.5 doesn't support the Classic emulation layer, but doesn't disable the capability to boot the system into Mac OS 9. It doesn't matter if the internal drive has one or two partitions.

    One thing that does matter is if the partition that Mac OS 9 was on, was reformatted.  If the reformatting did not include the Mac OS 9 drivers it won't be able to boot 9 until it does.  This article discusses that formatting: http://support.apple.com/kb/TA26834 Note formatting erases the drive.   So be sure to backup any data first before reformatting.

    Thank you Brody. I'll check out the link and see if it is something I can manage on my own.
