10.4: Install Tiger on older unsupported Macs
Authored by: syzygies on Feb 14, '06 04:40:57AM

There are conceptually two distinct hints here: A software hint on how to modify the installer to play nice with older systems, and a hardware hint on how to physically use the installer with older machines. These are entirely separate questions, and anyone who confuses these questions will experience unnecessary aggravation. The software hint is priceless, and the virtues of following the hardware hint are controversial. Rather than reburning the DVD, I would recommend instead following the related hint

10.4: Install OS X without first rebooting from DVD
It turns out (I successfully tested this) you can just run the OSInstall.mpkg located in /System -> Installation -> Packages on the DVD.

I now save OS installers in a folder, containing the disk image(s) and an alias to OSInstall.mpkg. After copying physical media to my frequently backed up "Sources" folder, I put it away and never touch it again. One can install from disk images to any volume except the startup volume; I always have multiple startup volumes available, to avoid ever having to revert to optical media.

10.4: Install Tiger on older unsupported Macs
Authored by: markmhart on Mar 01, '06 03:10:32PM

I've got a beige g3 mt 333mhz 384MB Ram, and I have tried EVERYTHING to get Tiger installed. I use xpostfacto 4, I've modified OSInstall.dist and reburned the dvd, and I've tried running install.mpkg directly from the disk image. I've made many changes to the OSInstall.dist program; right now, the machine checker and the rom checker both just return true.

The last dual-layer cdrom I burned went WAY into the install cycle before telling me I can't install on my machine. One stupid question just popped into my head - do I have to have 10.3 installed to install 10.4? I've got 10.2.8 on the beige, and I assumed a full-install of 10.4 wouldn't care what OS I have installed.

Any ideas out there? I would really love to have 10.4 on my beige.
