Apple extensively updates all software. The most important and most interesting innovation is Universal Control, which is now available for macOS 12.3 and iPadOS 15.4. With this function, you can use a mouse and a keyboard across Mac and iPad devices. As already known, the iPad can be used as a second monitor and can now also be practically controlled with the existing input devices.
As usual, security updates are also included, for example macOS Big Sur 11.6.5 and Security Update 2022-003 for macOS Catalina. In addition to the operating system, GarageBand (10.4.6), Logic Pro X (10.7.3) and Xcode (13.3) will also be updated.
Of particular note is an update to the Apple TV 3, which turns ten years old this month. With this, the software version increases to 7.9. So if you are looking for a cheap hub for HomeKit or another device with Toslink for your audio system, you can still get a good device that can be had very cheaply.
