My Macbook can not operate at a quite satisfied speed, and I want to enlarge my storage and change my hard disc to SSD in order to make my laptop upgraded.
1. Disassembling the back lid of the laptop
2. Find the hard disc and RAM and take down them
3. Installing the SSD and the new RAM
4. Installing the back lid
Find a clean space to do all these steps, pay attention to keep the inside of your computer clean and wear the anti-static wrist strap when you are working.
