We covered almost everything in non-metal. Now, let's turn our focus to legacy metal.

What is Legacy Metal? Think of "Legacy" as "Old." In other words, Old Metal graphics.

Throughout the years, Metal has changed and become better and more power efficient. In 2022-2023, Apple shifted gears with macOS Ventura and eliminated all machines with the older Metal Graphics system. Therefore macOS Ventura and newer have many bugs that are graphics related.

Most of these bugs, however, have many work-arounds. The main thing you will need to remember is that running macOS Ventura and newer will slow down a machine with Legacy Metal.
