It looks like my wife's MacBook Air (11-inch, Mid 2013) and my iMac (27-inch, Late 2013) will be able to run macOS Catalina. Damn! The longevity of a Mac is incredible!
Kiran has a MacBook Air which we just purchased as both high-school graduation (2019) and birthday gift (November). We did the same for her sibling in 2017. When she starts college next year I want her to be somewhat self-sufficient when it comes to tech support. I was thinking through the options for backing up her MacBook Air, and I realised that a Time Capsule would not be a viable solution.
Based on our visit to the college tour, we learned that the colleges she is considering (Oberlin, Smith, Mount Holyoke, etc.) provide campus-wide W-Fi. There are no Ethernet ports in the student residence rooms to connect a wireless access point or router. For the Apple Time Capsule, it could not be connected physically to a router or an Ethernet port. It's also not possible to connect the Time Capsule to the campus Wi-Fi as a Wi-Fi extender.
The bottom line here is that the Time Capsule has been designed to connect permanently to wired Ethernet, college residence halls do not have Ethernet, my daughter will need an external hard drive to use with Time Machine.
