Review on 💻 Enhance your Mac's Performance with Apple Memory Module 4GB 1066MHz DDR3 (PC3-8500) - 2x2GB SO-DIMMs by Prem Reyel

This module kit increased my 10 year old MacBook from 2GB to 4GB. My computer was getting slower and slower. I've gone through cleaning and performance procedures like deleting unused files, changing settings, etc. that really helped, but upgrading the RAM made the biggest difference by far. It's like a new computer for $16 and 15 minutes of work. Instructions can be found under About This Mac under Storage and all I needed was a small screwdriver. Removing old chips and installing new chips only takes a minute or two. If your MacBook behaves like it's dragging an anchor, open Activity Monitor and look for low memory. It will tell you if your memory is exhausted.
