Installing OSX on a Blue & White G3.

I went through the full gamut of installation strategies, in order to install Tiger on my mildly upgraded (DVD drive, 500MHz G4 JoeCard, 1GB RAM) Blue & White (Rev. A "Yosemite"). Apparently the Rev. A motherboards have all kinds of special needs, which are documented on a thoughtful page written by Bob at Headgap.com, a Mac resale store.

Installing Tiger if you don't have a DVD drive.

Mac OS X 10.4 Tiger now comes on a single DVD by default. While this is more convenient than the disc-swapping required by the 3 Panther CDs, it's tricky if you're trying to install Tiger onto an older machine that does not have a DVD drive.

I found an article by Jaharmi describing FireWire Target Mode (which I've also gone over) and a new technique involving using an external FireWire drive to create a dedicated partition that is a Tiger DVD disk image. Basically, you use Disk Utility to Restore the DVD to a spare partition you don't mind erasing. Handy if you have an extra FireWire drive lying around. I tried it this morning, and discovered a few things:

• The process requires you to erase a partition on your FireWire drive. This may require some thinking ahead.
• If you create a new partition, make sure you're generous in allocating space. Disk Utility will select the next lowest convenient number (based on the 1k = 1012 bytes formula, I expect) even if you try to get clever with your partitioning. The Tiger DVD takes up around 2.5 GB, so I tried to allocate just above that. The Restore process failed partway through, saying that there was some kind of file error. Giving the partition a full 4GB did the trick.
• If the Restore process does fail, both the source and destination volumes will remain unmounted. The visual indicator for this is pretty subtle (the volume names are greyed out in the list on the left, generally where you aren't looking) and you might be puzzled because further attempts to Restore will give you a "file not found" sort of error. The solution is to re-mount the target drive partition, and then use the File menu to eject the source DVD. Re-insert the DVD and it will mount.

The point of all this was to see if I could install Tiger onto my Wallstreet PowerBook via XPostFacto, which only has a CD drive. My quick experimentation with the new Tiger/FireWire partition described above resulted in a kernel panic. I'll have to look into this further, but for now I think the answer might be to send away for the Tiger CDs (see the "Media Exchange Program" box in the right column).

Tiger on iMac G3 (requires more RAM?).

I got Tiger working on my iMac G3 DV SE (a 400MHz slot-loading "Kihei" model). My initial attempts with the Tiger DVD led to the process hanging about midway through; I upgraded to 640MB of RAM last night and the install went off with out a hitch.

RAM's relatively cheap these days; the 512MB SDRAM module cost only $64 shipped from Omni Technologies, which has a goofy website (nearly all graphics and no text) but apparently makes their own chips and offers 24/7 customer support.

Installing Mac OS X via FireWire Target Mode.

Since the Power Macintosh G3 AGP, all Macs have supported FireWire Target Mode, the successor to the somewhat clunkier SCSI Target Mode. (Here's some history on the two.) Hold down the T key when your more modern Mac starts up, and it will magically turn into a FireWire device, visible to any FireWire-enabled Mac that you hook it up to. Any drives (optical included) will be at the disposal of the host machine.

MacOSXHints has a page that's chock full o' hints on how to use FireWire Target Mode on various machines.

This should be handy for installing Tiger onto the B&W G3 and the iMac G3; I was going to wait for the RAM upgrade for the latter, and haven't really figured out why the former keeps failing with the Tiger DVD.

A Tiger on Wallstreet.

After wiping some drives in eager anticipation, I ran into a small wall when attempting to install Tiger on the Wallstreet. I was puzzled until I figured out that that machine didn't come with a DVD drive, and Tiger is the first version of Mac OS X to come on DVD by default. (The Wallstreet won't tell you this, by the way; it will just tell you it wants to have a shot at formatting the installation DVD. In Pro-DOS format, no less.)

I have to figure out whether I can boot from a FireWire or other attached drive. I'm pretty sure the installations are machine-specific (e.g. I can't use the Titanium to install it one a drive and then transplant it). Either that, or take advantage of the Tiger Media Exchange (sidebar) by July 9th. Turn in your DVD and proof of purchase, plus $9.99, and Apple will mail you a set of Tiger CDs.

UPDATE I may have spoken too soon. It looks like someone has done the transplant successfully.

Experiments.

I did a couple of experiments last night: I upgraded the B&W PowerMac to Tiger, and upgraded the Wallstreet to Panther with the help of Ryan Rempel's excellent XPostFacto.

I'd actually done the XPostFacto trick before on this same PowerBook G3, but it didn't really take. The video had problems with colors, and overall it felt pretty creaky. But this time, I used his latest stable build, XPostFacto 3.1, read through the known problems, and decided to check the "Use PatchedRagePro" as suggested.

XPostFacto is very easy to use: just download the application to your OS 9 boot drive, insert your OS X Install disc, launch XPostFacto, check off a few options as necessary, and click the "Install from CD" button. Your Mac will restart and you then follow the normal procedure to install. Total time for me was under an hour. Not bad for a 7-year-old machine with just 256MB of RAM. Which reminds me; I should see about boosting that.

The Blue & White was just a bit less trouble-free: it reported that "there were problems while installing" and suggested that I try again. A casual Google revealed that sometimes this can be due to problems reading data off the disc, and since I had a relatively ancient third-party combo drive in there, I gave it another shot. The second time was a charm.

These were both test runs. When I get those laptop drives I ordered I'll stick one in the Wallstreet and try Tiger via XPostFacto 4.0b3.

Moving just your home directory in Mac OS X.

When I upgrade my work PowerBook (a 12" G4 at 1.33 GHz), I'll be doing a clean install of Tiger. Here's how to copy over just your Home directory after backing it up somewhere else:
