+### Darwin setup
+
+NOTE: this guide is for Oakhost Mac Mini M4.
+
+#### Setup temporary ssh keys
+
+```sh
+ssh-copy-id $USER@$IP
+```
+
+#### Setup passwordless sudo for admin group
+
+```sh
+echo "%admin ALL = (ALL) NOPASSWD: ALL" | sudo tee /etc/sudoers.d/admin-nopasswd
+```
+
+### Enable ssh access for all users
+
+```sh
+sudo dscl . change /Groups/com.apple.access_ssh RecordName com.apple.access_ssh com.apple.access_ssh-disabled
+```
+
+### Ensure that Xcode command line tools and/or application aren't installed
