Matcha

Matcha runs macOS Monterey in a melange VM.

Setup

Outside macOS

• VM noVNC kinda works ok; press the Windows key if you need to switch between windows of the same application by then hitting the backslash ` key.

macOS the way I like it...

Keyboard

• Install Karabiner-Elements key mapping tool, oh yeah
• Click predefined rules by community, search for 'PC-Style Shortcuts' pack, wowza

(ok that didn't handle Ctrl-Insert (copy) so I tried this one instead

• Go through all the macOS permissions loosening to get it working - you will NOT REGRET IT

Software

• Install XCode, EFI Agent, meld.
• Pay $3 and install IconKit, saves hours of work to build stupid icon packs

Installation

OpenCore VM

You can virtualize your old Mac hardware in a VM.  ;-)

You can follow thenickdude's awesome guide with these secret sauce bits to get going. I'll add some notes since those might disappear...

• Note that thenickdude's Monterey install wasn't working on July 3 2022, as it was pulling the wrong image from Apple. I used Big Sur and once running, immediately upgraded it to Monterey, which went flawlessly.
• Set up a OpenCore VM with an unclaimed serial using SMBIOS iMacPro1,1 to match up well enough with my AMD Ryzen 9 3900X 12-core processor.
• This helped to mount and access the EFI boot drive.
• I used a macOS release of my old fave Meld

macOS installation

• Set the hostname via Apple > System Preferences > Sharing (two places)
• Get MAC address from Apple > System Preferences > Networking and update dnsmasq to give out a static IP; renew lease on mac
• Allow SSH: Apple > System Preferences > Sharing > check Remote Login; then you can do the usual ssh config
• Update /etc/ssh/sshd_config to disallow passwords, and restart sshd:

sudo launchctl stop com.openssh.sshd
sudo launchctl start com.openssh.sshd

• set a banner in ~/.zshrc
