This was surprisingly hard to find—hat tip to Reddit’s Nakkokaro and xBl4ck. Apple’s instructions for restoring an iPad Pro (3rd generation, 2018) seem to be wrong; both me and an Apple Store technician found that the Finder, at least in Tahoe, won’t show the iPad once it reboots in recovery mode. The trick seems to be that you need to unplug the cable, start the reset process, and during the reset, plug the cable back in:

1. Unplug the USB cable from the iPad.
2. Tap volume-up
3. Tap volume-down
4. Begin holding the power button
5. After two roughly two seconds of holding the power button, plug in the USB cable.
6. Continue holding until the iPad reboots in recovery mode.

Hopefully this helps someone else!

Here’s what I did to get the Macbook Pro (rev 3,1) running smoothly under Ubuntu 9.04.

Turn on the nvidia drivers with jockey-gtk (the hardware drivers manager).
