===Deprecation of 32-bit support===
Apple notified developers that High Sierra would be the last version of macOS to run 32-bit applications "without compromise". Starting with the update to macOS 10.13.3, launching a 32-bit application would display an alert that it "is not optimized for your Mac. This app needs to be updated by its developer to improve compatibility." macOS Mojave (10.14) would be the final major release to even run 32-bit software at all.What Apple's 32-bit app phase-out on Mojave means to you by Gregg Keizer, Computerworld. 2018-07-09.
