Installing Ubuntu 24.04 on a 2014 Macbook Air

• Recommended: Use LVM + Encryption.
• Expect slow installation speeds (the ports are USB 3.0 but are stuck at 2.0 speeds during installation)
• Do not bother with installing proprietary components during OS installation; it is too slow. Do it post-installation.

Wi-Fi

• Wi-Fi will not work out of the box. You will need a USB Wi-Fi dongle to download Wi-Fi drivers from the Internet.
• After installing the OS, plug in your Wi-Fi dongle and run the following commands to update the system, install Wi-Fi drivers, and upgrade snap packages.
