macOS: How to turn your iPad into a second display with Sidecar.

If you haven’t tried Sidecar before, check out our full guide here: Sidecar is built into Mac and iPad since macOS Catalina and iPadOS 13.

We’ve used both here at 9to5Mac and have found them to be great products that see regular updates. Duet Display doesn’t require any hardware but goes from $25/year for Duet Air (to get Mac to Mac, PC to Mac, and iPad to Mac support).Luna Display does require a $119 Luna Display USB-C dongle but has no subscription cost.To get the same functionality that target display mode offers with Mac to Mac (and even get PC to Mac and iPad to Mac) support, Luna Display and Duet Display are two of the top options.
