Here's a few notes on apps I installed trying out elementaryOS 7 on a MacBook Air.
sudo apt install zsh vim git ansible
sudo apt install linux-headers-$(uname -r)
sudo apt install bcmwl-kernel-source
Download the .deb
file from 1Password
sudo apt install curl gnupg2
sudo dpkg -i 1password-latest.deb
sudo apt install qemu-kvm qemu-system-gui virt-manager libvirt-daemon-system libvirt-clients bridge-utils
Always restart the machine; the service won't run until you restart.
