When using a PowerPC Mac with Mac OS X 10.4 and 10.5, you normally don’t have the ability to use a single Keyboard, Mouse, or trackpad to move the pointer, type, and copy clipboard content across multiple Macs.
.

.
That is, until you download Teleport for Mac! A preference pane which lets you have a working “PowerPC version” of Universal Control. Universal Control has been baked into macOS since Monterey 12.3, and this .prefpane replicates most of the same features.

Turn on teleport

Before continuing, make sure each device meets the system requirements. Teleport for Mac v1.0.1 works on Mac OS X 10.4 Tiger or later, and 1.0.2 installs on Intel Macs. You may arrange Macs with both versions of teleport from a single Mac, whether it’s a PowerPC or Intel.

• Be sure both Macs are running on the same Local Area Network. A Gigabit LAN is recommended.
  .

On your Mac

• 1. Download the file and Unzip, then double-click to install. An admin password may be necessary if installing for all users of the computer.

• 2. Click Apple Menu > System Preferences.
  .
• 3. Click “Activate Teleport” and “Share this Mac”

• 4. Repeat the same process on your other Mac. This setting is only available once you installed the Preference Pane on both Macs.
  .

Connect your devices

After turning on Teleport, you can start to piece together the setup:

• 1. Drag-N’Drop the Mac you’re looking for, from the selection area up top, and arrange it to wherever you’d like in relation to your screen.

• 2. Your other Mac may ask for a password, or ask to Accept incoming connections.
  .

.
When you jump over to another Mac, it will show it on the screen of the other Mac, as well as your “control” Mac, depending on your setting.
.

.
Modify your experience

In Teleport, you’re able to customize your experience:

• Enable encryption and create a self-signed certificate using Mac OS X’s built-in utility.
  .
• Control request settings (Ask to trust, reject if not already trusted, or auto-accept)

• Add deliberate time-delay to the switch

Enable/disable:

• Double-Tap screen border with mouse to switch to next Mac.
  .
• Drag-N’Drop files between Macs
  .
• Pasteboard syncing, pasteboard sync with keypress, size limitations
  .
• Attempting to wake sleeping Macs
  .
• Appearance in Menu Bar, as well as desktop bezel appearance when switching Macs
  .
• Auto-check version (this is abandonware, you may un-check this).

In Conclusion

I used to use this back in the day on my Power Mac G4 daily driver, and other desk setups where I had multiple Macs. I remember this app being particularly useful when I was repairing a bunch of iMac G3s, setting them up to all run on Mac OS X Tiger.

I had more network cables and ports on the router to spare than keyboards and mice, and this was a convenient solution years ago. This takes me way back to 2010-11, when you could still mostly use a G4 on the web. These are some actual pictures of some of the setups I had back in the day! Each of these setups had Teleport on them, the app being mostly useful in a pinch or for a specific task.
