Have you recently started to see an alert indicating that one of your applications is not optimized for your Mac? This is a new alert that Apple added in macOS High Sierra version 10.13.4. This alert appears for older applications, what are called 32-bit applications. It’s important to understand that these older applications will continue to work fine as long as you use macOS High Sierra. Nothing is wrong. Nothing is broken. Apple is just giving users a heads up.
In 2017, Apple announced that macOS High Sierra would be the last version of the Mac operating system to support 32-bit apps without compromise. The meaning of the phrase “without compromise” is not entirely clear. It might mean that 32-bit applications will not work at all with High Sierra’s successor, or it could mean that they might work but with some limitations. Thus, it’s time to either upgrade or replace your older 32-bit Mac apps. Read More from “Upgrade Or Replace Your Older (32-bit) Mac Applications”
