Compressed air for cleaning out dust from the laptop’s internals.I bought a Smart Phone Repair Kit here in Australia, you may want something similar from Amazon. P5 Pentalobe and T5 Torx screwdrivers.The iFixit Mac Laptop Repair guides provide excellent step by step instructions for SSD replacements specific to each model. Make sure you have the right equipment for performing the upgrade. These are the 2 machines I updated, named for Futurama characters.
has thorough descriptions of each model, use About This Mac-> System Report to gather up all the details of your system. Take the time to figure out exactly which model you have before getting starting. The total cost was under $90 USD each for upgrading to 500 gigagbyte drives. Go read at least the first page of that thread if you have questions I don’t answer, there are 220 pages of feedback so far. There is an amazingly thorough thread on this, but I figured I’d post my experiences upgrading 2 of my laptops that I’ve upgraded so far. Relatively recently (10.13) it became possible to upgrade these systems with an aftermarket adapter and stock NVMe M.2 form factor SSDs. The SSDs used by MacBook Air and MacBook Pros shipped between 2013-2017 used a proprietary adapter. I just used my iMac as an example to make the above images.Apple laptops are somewhat notoriously resistant to upgrades. Note: I do know that 2011 iMac's can accommodate an internal SSD without removing the existing HDD or optical drive. Here the Link Speed is 6 Gigabit, so a SDD replacement would be able to operate at its maximum transfer rate. My 2011 iMac shows the following for the HDD drive. So, it would be worth the money to replace my optical drive with a HDD but not a SSD. Anything less will often still work, but the drive will not be able to transfer date at its maximum speed. HDD's require at least 3 Gigabit and SSD's require 6 Gigabit to operate at their maximum transfer rate. What is important is the Link Speed of 3 Gigabit which is the maximum for the controller.
Negotiated Link Speed is 1.5 Gigabit which is normal since most optical drives transfer data at less than this speed. For example, my 2011 iMac shows the following for the optical drive. This can be view using the System Information application. The first question to answer would be the link speed capabilities between the controller and the optical drive.
