With upcoming macOS Catalina and iPadOS, a new feature was added – Sidecar. Essentially, you can connect an iPad to your Mac – by cable or wirelessly – and enjoy an additional space for your Mac. As I’m not developer and I don’t have a developer account, I can’t try it on myself yet, but reports say that it works like a charm. You can find many videos on YouTube, as I did. But there is raising a question: what happens to software like Duet Display or Astropad or even to Luna Display as hardware solution?
Yes, this new feature may cause many problems for developer of solutions like Duet Display. But we must realise, that this is not death for such solutions. I will explain it on Duet Display.
First, for Sidecar you need macOS Catalina and iPadOS, which are still in beta. Even after final release, there is another issue: Sidecar is not supported on all Macs running macOS Catalina. The only supported Macs are:
- MacBook Pro (Late 2016 or later)
- Retina MacBook (Early 2016 or later)
- MacBook Air (2018 models only)
- Mac mini (2018 models only)
- 27-inch iMac (Late 2015 or later)
- iMac Pro (all models)
- Mac Pro (2019 models only)
So there is a chance that your Mac will not be compatible. I’m owner of 5K iMac from late 2015, so I’m happy that my Mac is supported, but many users of older Macs, including 2014 version of 5K iMac, are out of luck.
Now look at Duet Display. You need any Mac with OS X 10.9 (Mavericks) or later or PC running Windows 7 (or later). As for iOS devices, all iPads and even iPhones and iPods touch are supported – just make sure you are running iOS 8 or higher (Note: iOS 7 is supported by earlier versions of Duet Display for iOS, but you will also need an earlier version of Duet Display for Mac/PC).
So if you are unable to use Sidecar, there are still solutions like Duet Display, Astropad or Luna Display. I’m former user of Duet Display, which is great, and it also supports Apple Pencil, so this is a great alternative for users of Windows PCs and older Macs not supported by Sidecar. Also, Sidecar requires iPadOS, while Duet Display, as was mentioned, runs on all devices running iOS 8 or later.
