Installing Mac OS on KVM

Background

I first tried to install Mac OS onto a VM back in 2010 or 2011 I think. I’ve come back to the task from time to time and have never been successful, but truthfully until recently all the virtual machines I’ve created on Cinnamon had been too slow to be useful anyway. Now that I have Cinnamon doing virtual machines well, I came back to the Mac – at the same time I was doing other VMs, and I didn’t keep careful track of what I did to get it up. This document is meant to record what I remember of what I did the first time, and then to do it again and keep better records.

Packagekit adjustments in ubuntu

When I tried to upgrade Cinnamon to Focal, I began to experience a lot of odd problems with VNC and GDM and the whole collection of machinery associated with getting a graphical environment particularly in a remote window. Cinnamon is physically downstairs in a rack in the basement, and my usual way of working is 80-90% ssh/command line and occasionally vinagre in an adjacent monitor with screens for a dozen or so places that I occasionally need to see graphically, including Cinnamon, but Vinagre usually stays pointed at Rosemary (also in the basement).

Timemachine on Gateway pi

Some people for whom I provide some kinds of support with gateway pis, use Macs. For the pc folk – at least for those on Windows 10, I’ve been seting up to do the filehistory thing, and putting the filehistory onto the /backup drive on the gateway pi. Then it gets sent here overnight. I wanted to do the same for the folks who have Macs, of which there are several.

libmtp udev rules

After updating Arch today I found I could no longer mount usb storage devices – usb sticks. The log shows the device coming up, but then messages from MTP saying: 

mtp-probe: bus: 2, device: 5 was not an MTP device

I have seen this before. It is irritating, I am doing something else, my head full of whatever it is, and suddenly usb sticks won’t mount.
