Supplies for the iMac 

Preparing backup and boot media for the iMac. Want to look at 

1. 2x OS's (Chrome Flex, Ubuntu), 

2. 1x Backup of Mac OS Installer, 

3. 1x OpenCore Patcher 2.2.0 Experiment. 

4. TailScale Experiment.

In theory, I can bring this machine to Mac OS 15 with the latest version of OpenCore Patcher 2.2.0

You can adjust the resolution of the display here—set it lower if your presentations tend to lag. You can also click the "Arrange" button to decide which side of the screen you need to move your mouse to in order to enter the virtual display. This is a little confusing, granted, but you need to pretend that the DeskPad window is another monitor on your desk. Play around with it and you'll get the feel for it.

Now you can get ready to give your presentation. Put your presentation software in the virtual, DeskPad display and set it to full screen. Then, when sharing your screen in Zoom or similar software, choose the DeskPad display.

Zoom will share the entire virtual display as though it's a real one. Now you can organize your screen just the way you like it. With the presentation in full screen in the DeskPad window you can have your notes and anything else in separate windows alongside it. It's a bit of a hack, sure, but it works.
