And then finding out the projector is VGA-only, which is still common in many places.
Or that it would support HDMI if only you’d packed a stepladder and a 20’ HDMI cable, but the cable on the desk is VGA. Just when this was starting to be a thing of the past, Apple dropped HDMI from the MBP. Magical.
...and there’s no dongle to connect my collection of MiniDP-to-VGA dongles to USB-C (n.b. No, a USB-C to MiniDP won’t do it unless it adds DP++ support).
Thing is, we accepted sometime in the 00s that VGA was not only just too big to build into a Mac laptop, but that the low (analogue) quality and resolution was thrashed by DVI, HDMI and DP. Trouble with USB-C is that it’s just the same old DisplayPort - and not even DP++, so you need active adapters - all that USB dongle gets you is back to square one.
Of course, I’m sure that every last data projector/giant video wall on Apple campus has Airplay... and if we endure our cabling trials and dutifully worship the One True Connector at the altar of the Upturned Mouse then we’ll be transported there in the next life.
