EDIT: To be fair, although it got stuck for a while, it managed an update.
Yay.
And it did detect the mouse/keyboard on reboot - which was a bit of a worry, some people online seemed to have an issue with that - and that what happens on the MacBook Pro - from Bootcamp, it detects the bluetooth and mouse, but from MacOS - nothing, so I have to logon using the laptop keyboard then it's OK
The Mini seems much better so far than the Pro - better connectivity, better built-in interfaces (Two usb-c/Thunderbolt, two USB 3.0, Ethernet port, audio I/O, HDMI, better plug, better detection (Once installed and running) of devices.
I can take my time and have a play around with it now. What good free shit is available for this (not pirated crap!)
Also.. also.. it's bluetooth is superior to the Macbook Pro. With that, I have a super-dupe K780 keyboard and it refused to identify it properly. When I did the 'test key' (to the right of shift) - it said "You've pressed your Apple keyboard
)
This one detected it, then gave me the option to set it up as a standard 101 key ANSI keyboard. So I can at last use my Numeric keyboard!!!!! This was impossible to do on the Macbook Pro - despite trying different stuff for several hours, it just wasn't having it and this did it straight away.
From what I've seen so far, if they'd given me a Mac Mini from the start then I'd have been a lot happier.
