EveryMac.com's 'Retina Display' MacBook Pro Q&A answers questions about the 2012, 2013, 2014, and 2015 MacBook Pro models that are crafted from a single piece of aluminum and have a 13-Inch or 15-Inch 'Retina Display.'
These notebooks do not have a name on the display bezel (they only have 'MacBook Pro' text on the bottom of the notebook). They also lack an optical drive, so collective identification is possible by these two points alone. However, they additionally can be spotted by model numbers A1398, A1425 and A1502.
Questions range from 'How do you upgrade or replace the storage in the Retina Display MacBook Pro models? Is it even possible?' to 'Is there a 'hack' to switch between graphics processors on the Retina Display MacBook Pro models manually?' and include everything in between.
Please note that all Retina Display MacBook Pro models have been discontinued.
The previous 'Unibody' MacBook and MacBook Pro systems have 'MacBook' or 'MacBook Pro' text on the bottom display bezel and have internal optical drives.
These 13-Inch, 15-Inch, and 17-Inch notebooks are model numbers A1278, A1286, and A1297, respectively.
EveryMac.com offers separate 'Unibody' MacBook Q&A and 'Unibody' MacBook Pro Q&A that cover these earlier models.
EveryMac.com covers earlier 'pre-Unibody' MacBook Pro models, sold from 2006 until 2008, in the Original MacBook Pro Q&A as well as later 'Touch Bar' MacBook Pro models, sold from 2016 to 2021, in the 'Touch Bar' MacBook Pro Q&A and current MacBook Pro models in the 'Apple Silicon' MacBook Pro Q&A.

- Shut down your MacBook Pro. Disconnect the power adapter, Ethernet cable, USB cables, security lock, and any other cables connected to the MacBook Pro to prevent damaging the computer.
- Turn over your MacBook Pro and remove the ten (10) screws that secure the bottom case. Because the screws are different lengths, note the screw lengths and locations so you can replace the screws correctly. Put them aside in a safe place. Lift off the case and place it to the side.
- Touch a metal surface inside the computer to discharge any static electricity from your body.
Step 2: Remove existing memory (if present)
- Push the levers on the sides of the memory module in an outward direction to release the module from the memory card slot. The memory pops up at an angle. Before removing it, make sure you find the half-circle notches. If you can't find the notches, try pressing the levers outward again.
- Hold the memory module by its notches and remove it from the slot.
- Remove the other memory module.
Important: Hold the memory modules by their edges; do not touch the gold connectors.
Step 3: Install memory
- Align the notch on the gold edge of the module with the notch in the lower memory slot.
- Tilt the card and push the memory into the slot.
- Use two fingers with firm, even pressure to push down on the memory module. There should be a click when you insert the memory correctly.
- Repeat this procedure to install an additional memory module in the top slot. Press down on the module to make sure it is level.
Note: Make sure your memory is installed according to the illustration below, with the gold contacts inserted almost completely into the connector.
Step 4: Replace the bottom case
Replace the bottom case. Replace and tighten the ten screws you removed earlier, making sure to put the different length screws in their proper locations.

Checking that your computer recognizes the new memory
After installing additional memory, you should confirm that the computer recognizes the new memory. To check the computer’s memory:
- Start up your computer.
- When you see the Mac OS X desktop, choose the Apple () menu from the upper-left menu bar, then choose About This Mac.
The total memory includes the amount of memory that originally came with the computer plus the new memory you added, or if all the memory has been replaced, the new total for that memory. For detailed information about the amount of memory installed in your computer, open System Profiler by choosing Apple () and then About This Mac. Then, click More Info and then Memory from the Hardware section that appears in System Profiler.
If your computer doesn’t recognize the memory or doesn’t start up correctly, confirm that the memory you installed is compatible with your MacBook Pro and that it is installed correctly by reseating the memory.
