With the release of macOS Catalina 10.15 Beta we get a sneak peek at “Sidecar” which allows users to use an iPad as a display. What I soon learned was that my 2013 MacBook Air was not supported.

I then came across the article on AppleInsider that showed us a command to allow Sidecar on a Un-Supported Mac. This video shows how it works in just a few seconds.

The command was originally posted by @stroughtonsmith

Sidecar supports iMac 27" (Late 2015) or newer, MacBook Pro (2016) or newer, mac Mini (2018), Mac Pro (2019), MacBook Air (2018) , MacBook (Early 2016 or newer), and blacklists all the devices in the screenshot pic.twitter.com/DHNDyI98WV — Steve Troughton-Smith (@stroughtonsmith) June 5, 2019
