You cannot. With the introduction of the MacBook Pro Retina line in 2012, it's not possible to upgrade your RAM as you could with previous MacBooks.
No.
Click the link I will post to Crucial. They will scan your MacBook and tell you exactly what ram and how much you can install.
A Macbook Pro weighs around 5.6 pounds (2.54 kg).
Apple sells only only one version of the Macbook Pro 15". You can upgrade the processor, ram, hard drive, and display if you wish. If you are using this Macbook as a student, I would recommend you get the Macbook Pro 13" base model and save yourself $600. It is all a student will need. However if you are looking for the best laptop you can get for your own use then the 15" is the best of the best. Unless you are doing graphics and or video editing you have no need to upgrade it. Only you know what you need.
The latest 15 inch MacBook Pro will support up to 4GB and the 17 inch version will support up to 8 GB of RAM.
It all depends on what you need it for.If most of what your doing is taking notes, web browsing, word proccessing, etc, then the MacBook Air should be fine.If your an enginering student, doing HD video editing or other heavy processer work then the MacBook Pro would be better for the long run.With the newer Apple laptops you will need to max out the ram as you won't be able to upgrade later as the ram is permanently install.
The 2.4GHz MacBook Pro is designed to support 8GB of RAM without any problems. Most users will find the standard 4GB perfectly adequate.
To upgrade MacBook RAM, one must first purchase RAM that is compatible for your specific brand. Once done, open the casing. There are usually 8 screws that secure the bottom case of the MacBook. Push the ejection levers in an outward direction and release the module from the slot. Align the new memory module and push down evenly. Close up and the job is done.
Gigabytes (GB) vary with the model of Macbook Pro you decide on. 13-Inch MacBook Pro has 4GB memory and a 500GB hard drive. 13-Inch MacBook Pro with Retina has 8GB memory and ranges from 128GB flash storage to 512GB flash storage. 15-Inch MacBook Pro with Retina has 16GB memory with either 256GB or 512GB flash storage. This information comes from the Apple Store website.
There are a number of places where one could go to learn about the RAM of a Macbook Pro. Specs for computers are found in numerous places online, like Best Buy and Future Shop's websites. Information can also be found in any computer store or electronics store that sells the Macbook Pro.
Gigahertz (GHz) is the speed of the processor. The size of RAM is measured in Gigabytes (GB). The 2.16GHz MacBook Pro can have 2GB (two 1GB modules) of 667MHz PC2-5300 DDR2 SO-DIMM SDRAM.
See, an RAM upgrade will give you the power to run more programs without any lag. If your current computer runs without hanging and you just want a speed boost then you may consider an upgrade in the processor. I recommend you to see Intel i3-3200 processor. It is much better then core2duo and not very expensive.
