I’m currently using an iMac with a 23.7” LG UltraFine 4K external monitor (read my review here). With the M1 Mac mini coming today, this setup will have to change. The LG screen will transit to the Mac mini and I’ll lose the pleasure of the second screen working environment. Using the macOS virtual desktop feature is nice but not always the best solution when working on many different things at once. This is where Apple’s Sidecar comes into play. Prior to this, I rarely used Sidecar, but not anymore. I’ll use it with the Mac mini or the iMac, depending of the current work session. As a bonus, I get to use a “soft" Touch Bar at the bottom of the display, which is cool because I love the Touch Bar.
