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 20192020 Catalina and Big Sur 20202021 as well.

DISCLAIMER: I would highly recommend to perform a back up like a Time Machine backup of your system before following this tutorial. I am not responsible if something goes wrong and you lose data etc. I have performed the steps in this video hundreds of times with iMacs, iMac Pro, MacBook Pro, Air, and Mac Pro desktops with no issues. Please follow my instructions carefully for the best results.
