  • Tips for speeding up macOS without hardware upgrades: optimizing system performance, reducing latency, and improving computer speed through software settings and maintenance.
A Trees Admirer Hi everyone! I hope that you enjoy this summer.

I want to tell something very personal about myself (some of my readers complain that this blog is too technical). I want to share my secret with you, don't tell anyone ;) I am a secret admirer of trees and nature! I think trees speak with the Universe and can tell us about everything should we listen patiently!

Enough secrets (they might be misleading!). Let's get technical!

How to Speed Up macOS Without Hardware Upgrades

After a while, my macOS computer started to work slower. I have searched for possible solutions to run my computer faster without much latency. We can upgrade our computer storage and install a more powerful processor to speed up macOS, but hardware upgrades are costly and take time. This post instead focuses on three software-only maintenance steps that reclaim disk space and free memory:

  1. Clear macOS caches in ~/Library/Caches
  2. Empty the Trash
  3. Free RAM with the sudo purge command

Clearing caches, emptying the trash, freeing RAM and a cleanup script follow below.
