Replaced Screws and HDD
The screws on my used Macbook Pro were really stripped, and my hard drive was failing.
It went great! Screws came in time, and I completed the replacement in minimal time.
Remember to buy the appropriate screwdrivers for the repair. I used a Phillips 00 and 0. Also remember to make a Recovery USB, so you don't have to use Internet Recovery, and then updating to the latest OS.
