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...

System Config

• 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

Keyboard

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

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
