I've got an 2011-era Mac Mini that I've loved for developing - updated to 8GB of RAM + an SSD, it's been a great Xamarin machine for years. However now I'm looking for a replacement as Mojave won't support the hardware. With the dated Mac Mini and reports of many keyboard issues on Macbook Pros I'm looking at a Mac Air for a new development machine - and even these are getting a bit long in the tooth. Not really sure what Apple is up to these days.
