Dashboard isn’t the only thing gone in 10.15 — so is 32-bit app & plugin support, Carbon, Ink, QuickTime 7 & QuickTime plugins, PPTP, and hardware RAID. You will get Python 3.7 and Ruby 2.6, at least 😜
This fall, the Mac will move fully into a 64-bit world, and with it many old applications and services that users may still rely on today in Mojave. And as James Thomson pointed out, it’s also the end of any remaining Newton codebase.
