So How Does Sidecar Work?
Apple’s remote display software is quite similar to Due Display and Luna Display in terms of functionality. Based on your need, you can use the virtual display technology to extend or mirror the desktop. As mentioned above, it is designed to work over both wired and wireless connections. When using the wired connection, you would need either USB-C to USB-C cable (for new iPad Pros) or USB-C to Lightning cable depending on the iPad models. As for efficiency, the wired connection cuts down latency issues and helps the virtual display work a bit more smoothly. When using this feature over a wireless connection, ensure that your devices are within a range of 10-meters. Initially, the technology uses Bluetooth for quick connection, then after it takes advantage of point-to-point Wi-Fi for data transfer. One more thing worth noting is that your iPad and Mac must be logged into the same iCloud account as well. A Step In the Right Direction… Now, you no longer need to use third-party apps and hardware to turn your iPad into the secondary display for your Mac. Ever since I started using Catalina and iPadOS, I have been using this feature. And I must say that it has further enhanced the Continuity that has long been a great feature in the Apple ecosystem.
