What do you think will be the requirements for macOS 10.14? Another year of the same requirements as Sierra and High Sierra? Or a new tier of requirements?
I'm predicting the latter, killing off my 2010 Core i7 iMac. Here are my guesses:
Early 2011 or newer MacBook Pro with Thunderbolt
Early 2011 or newer iMac with Thunderbolt
Late 2017 iMac Pro with Thunderbolt
Mid 2011 or newer Mac mini with Thunderbolt
Early 2015 or newer MacBook with USB-C
Mid 2011 or newer MacBook Air with Thunderbolt
Late 2013 Mac Pro with Thunderbolt
Not sure about the Mac Pro. The 2010 and 2012 are very similar, and both are without Thunderbolt, which didn't arrive until the trashcan Mac Pro in 2013. If I had to pick, I'd guess the 2013 would be the minimum, so no more cheese grater Mac Pro support. That would annoy a lot of people though, since the Mac Pro is the most expensive Mac, but with the shortest longevity for OS support.
It will be interesting to see what they specify for RAM. Cuz if 4 GB, then a lot of of the Airs would be excluded. But that may be a good thing, as 10.14 could run like @ss on 2 GB RAM, maybe also in small part because all applications on 10.14 would be 64-bit only. But I'd guess they won't make 4 GB a requirement until 10.15 in 2019.
So, my arbitrary prediction is that to get macOS 10.14, the Mac either has to have Thunderbolt of some sort or else USB-C.
