I should note that G3s and G5s are very hit or miss. I also found this page that I quite liked: http://hints.macworld.com/article.php?story=2336384.

To use a keyboard shortcut, press and hold one or more modifier keys and then press the last key of the shortcut. For example, to use Command-C (copy), press and hold the Command key, then the C key, then release both keys. Mac menus and keyboards often use symbols for certain keys, including modifier keys:


On keyboards made for Windows PCs, use the Alt key instead of Option, and the Windows logo key instead of Command.

Some keys on some Apple keyboards have special symbols and functions, such as for display brightness , keyboard brightness , Mission Control, and more. If these functions aren't available on your keyboard, you might be able to reproduce some of them by creating your own keyboard shortcuts. To use these keys as F1, F2, F3, or other standard function keys, combine them with the Fn key.

Cut, copy, paste, and other common shortcuts

  • Command-X: Cut the selected item and copy it to the Clipboard.
  • Command-C: Copy the selected item to the Clipboard. This also works for files in the Finder.
  • Command-V: Paste the contents of the Clipboard into the current document or app. This also works for files in the Finder.

Here are some notes on how I set up an installation of OS X Tiger (10.4)on an emulated PowerPC G4 using QEMU,on a modern x86_64 Mac.

Mac

This setup was performed using QEMU 5.0.0 (obtained via brew install qemu).

Note: at some point during this process -cdrom /dev/cdrom seems to have stopped working, but -cdrom /dev/disk2 works.

Step 1: Initial installation

In this step we will format the disk and perform the initial OS X installation.

Download a copy of the2Z691-5305-A OS X Tiger installation DVDand burn it to a physical DVD.

Note: for some reason qemu does not seem to be able to boot .iso files of the OS X installation DVD (using -cdrom tiger.iso),but if you burn that .iso to a physical DVD and then use -cdrom /dev/disk2, it works.

Boot the DVD to verify it works:

If you see the grey Apple logo, the DVD is working correctly with QEMU:

Quit QEMU and create a 127GB QEMU disk:

Boot the install DVD with the disk attached and being the installation. QEMU will exit when the installer reboots.

When the installer reaches the disk selection screen, there will be no disks to choose from, because the disk has not been partitioned yet:

Start up Disk Utility:

'Erase' the disk to partition and format it:

Quit Disk Utility and the installer should now see the newly formatted partition:

The install will take quite some time (over an hour). When it completes, it will reboot, which will cause QEMU to exit (due to the -no-reboot flag).

At this point you may (physically) eject the installation DVD (from your host Mac).

Mark the disk as read-only to prevent any accidental writes to it (which would cause any snapshots based on this disk to become corrupt):

Step 2: User account creation, system updates

For

In this step we will create a user account and install all of the system updates. Microsoft office 2011 for mac os torrent.

Create a snapshot of the disk (think of this as forking the hard drive):

The system updates can either be installed using the Software Update utility (iteratively repeated across many reboots),or you can download and install them manually.

The manual route is quicker because some of the updates are bundled, and you don't have to wait on Software Update to detect which updates have / haven't been installed yet.

To install the updates manually,download (on your host Mac) item #29 (Tiger_Updates.dmg_.zip)from the 'Mac OS X for PPC' pageof macintoshgarden.org.

Unzip that file and convert the dmg to a DVD image:

We can now use tiger-updates.cdr as a virtual DVD with QEMU.

Boot the G4 and create a user account:

Note: if you plan on using Software Update rather than tiger-updates.cdr, you man omit the -cdrom tiger-updates.cdr line from the above command.

Note: this boot may take several minutes to get started.

This install was set up with user macuser and password macuser:

This installation was set up with the Central timezone:

Disable the screen saver and power-saving features:

Open up System Preferences and:

  • Display & Screen Saver -> Screensaver -> Start screen saver -> Never
  • Energy Saver
    • Put the computer to sleep when it is inactive for -> Never
    • Put the display to sleep when the computer is inactive for -> Never
Mac

If you did not use Software Update, open up the Tiger_Updates 'DVD' and install all of the updates:

If you go with the updates DVD route, make sure you run Software Update at the end just to be sure you've covered everything.

Mark the snapshot read-only to prevent accidental writes to it:

Step 3: Web browser, video player, text editor

In this step we will install TenFourFox, VLC and TextWrangler.

Create a snapshot of the disk:

TenFourFox is a fork of the Firefox web browser which is currently supported on Tiger/PPC.Their website links to the latest version,FPR22.

The latest version of VLCfor Tiger/PPC is 0.9.10,which is still available from their downloads page.

The latest version of TextWranglerfor Tiger/PPC is 3.1,available via Bare Bonesor macintoshgarden.org.

Strangely, no combination of using Disk Utility and hdiutil to create .dmg or .cdr images of TenFourFox.app seemed to work with Tiger:

Note: in retrospect, perhaps this was an APFS vs. HFS+ issue?

I resorted to burning TenFourFox, VLC, and TextWrangler to a physical DVD and passing it through to QEMU.

Note: even burning to a physical CD-ROM didn't work -- it had to be a DVD.

Drag the applications into /Applications.

Shutdown the G4 and mark the disk read-only:

Step 4: Xcode, Tigerbrew

In this step we will set up a development environment for building modern Unix software.

Create a snapshot of the disk:

The latest version of Xcode Tools for Tiger/PPC is 2.5,which is still available via Apple (search for 'xcode 2.5' at https://developer.apple.com/download/more/, requires login),or via macintoshgarden.orgfrom their Xcode page.

Again, I had to burn this to a physical DVD in order to use it with QEMU.

Boot the G4 and install the Xcode Tools:

Tigerbrewis a fork of Homebrewfor PowerPC Macs running Tiger or Leopard.

Open up a terminal on the emulated G4 and use the following commands to install Tigerbrew:

Also, change Terminal.app to spawn a 'login' bash shell:

  • Terminal -> Preferences -> Execute this command -> /bin/bash -l

Don't forget to mark the disk image read-only:

Using these QEMU hard drive images

At this point we've created a series of four chained hard drive images:

We can squash these images into a single, combined, stand-alone hard drive image:

We can then boot using that combined image directly, without the use of any snapshots.This is analogous to having a real Mac with a physical hard drive:

Or, we could treat combined.qcow2 as a 'golden master'and create snapshots based off of it, perhaps to try out some experimental tigerbrew packages:

Perhaps in experiment-1.qcow2 we try out gcc-7, and in experiment-2.qcow2 we try out llvm, etc.

Each of these snapshots can be used with the above command line as the -hda argument:

  • qemu-system-ppc .. -hda experiment-2.qcow2

We could even create further branches off of e.g. experiment-2.qcow2:

Perhaps we decide that experiment-2B.qcow2 was the keeper and the rest can be gotten rid of?

Mac Os X For G4 Chromebook

combined.qcow2 now contains the changes from experiment-2.qcow2 and experiment-2B.qcow2.

Thus far we've been branching off of the 'tip',but we could just as easily branch off several points in the snapshot tree.For example, if we hadn't merged the images into combined.qcow2,we could make a 'daily driver' snapshot for web browsing based off of 3-browser.qcow2,and a 'dev box' for doing development work based off of 4-tigerbrew.qcow2:
