Even in 2021 after a while all Mac computers can become slow and needs to be restored to a faster state. A reason why the Mac can become slower can be due to system or user error, it can slow the performance of your system to almost unusable. In this video I show you a few tips in what an Apple Store Genius Bar would do to speed it back up again. After doing these changes on your mac it should run much faster. Specifically, I am going to show you how to speed up the 2018 & 2019 OSX Mojave 10.14.5 on a 2018 MacBook Pro and make it go fast! This can also be done on the latest 2019-2020 Catalina and Big Sur 2020-2021 as well.
