2021 Annual Rickies
Pick conditions: 5
"No Intel Macs are available for sale without an Apple Silicon counterpart." Myke points out the iMac Pro as a potential spoiler.
(For pick complexity purposes, I'm counting this as 1 condition for each Mac line that still had no Apple Silicon counterpart at the beginning of 2021: The larger MacBook Pros, the iMac in both sizes, the iMac Pro, and the Mac Pro. The Mac mini is 1 line with a high end and low end, so it already had an "Apple Silicon counterpart" although the high end Mac mini was still Intel.)
The iMac Pro left the lineup entirely, but the Mac Pro remained on Intel by the end of the year.
