Those discs can typically be obtained by calling AppleCare if you lost them, or asking the original seller of the machine to give you the restore discs. This will also allow using Classic in the Tiger booting session if installed from the Mac's original restore discs:Īnd/or retail installer for 9 if newer than those discs. Partitioning will wipe the contents of the hard drive, so backup your data at least twice before proceeding. It is possible to add an external firewire hard drive, or partition an existing hard drive of a Mac that supported Tiger to have a dual-boot Tiger/Leopard configuration on 867 Mhz G4 and faster PowerPC Macs. While older Macs may work with Leopard with a special Target Disk Mode based install, this is not an officially recognized configuration, meaning any attempt to do so is on your own, with all the risks of maintaining and upgrading that configuration up to you.īackup your data at least twice before attempting any upgrades.

Check with the third party manufacturer of the CPU upgrade card if that is possible.įor more on 10.5's offerings, see this tip. Some CPU upgrade card Macs may support dual booting. No iMacs, nor iBooks meet the requirement.

To get those Macs to support Mac OS 9 booting, an erase (yes that means losing all data presently on that disk) and install requires installing with Mac OS 9 drivers before installing Mac OS X or Mac OS 9, as this article explains: Powerbook G4 867 Mhz and greater with rear USB ports between the hinges under a flap. PowerMac G4 1 through 1.25 Ghz MDD with no Firewire 800 port (see below)* 13 years separate their release.Ī few Macs officially support both booting into 9 and 10.5 without an additional partition or hard drive with booting via Apple menu -> System Preferences -> Startup Disk in 10.5, and Apple menu -> Control Panels -> Startup Disk in 9 or booting holding the X key on a restart from Mac OS 9 boot. Mac OS 9 is not to be confused with Mac OS X 10.9, Mavericks, of the similar name. Macs too old to install Mac OS X, can only install up to 9.1 if they are PowerPC (except the ones that are 53xx/54xx/63xx/64xx and fail its firmware test and those can only install up to System 7.5.5). Booting into Mac OS 9, only requires the Mac OS 9 that is the same age or newer be installed in the Mac. Macs that date on/later than 9.2.1's Augrelease must use their original installer disks to install Mac OS 9. Classic requires there be a Mac OS 9 system folder present with Mac OS 9.1, 9.2.1, or 9.2.2. Multiple disk games frequently require imaging all the discs and mounting first while using Classic, when booting into Mac OS 9 allows hot swapping of the same physical discs. Many drivers that booting into Mac OS 9 are not supported in Classic environment.
Built-in support for Classic is gone in 10.5 and Intel Macs:Ĭlassic, is the ability to use Apple menu -> System Preferences -> Classic to run Mac OS 9 simultaneously with Mac OS X, and access Mac OS 9 applications from Mac OS X without having to go through Apple menu -> System Preferences -> Startup Disk to select Mac OS 9's System Folder.
