Can Someone confirm if this works on MacBook Pro (13-inch, Early 2011). I currently have 4GB RAM. Thank you. Guru

That's what I have. This memory kit made an incredible difference! Just to be safe, click on your apple menu, then "about this Mac". Make sure it says "1333MHz DDR3". You should be good to go. Enjoy

I have a MacBook Pro (15-inch, Early 2011) and bought these last November. I thought they were great. Now (Sept2015) they are causeing issues and the repair people at Apple took them out. :( So I say don't buy them.

This RAM will NOT work in any laptop, it is desktop Mac Pro RAM. It is not designed for a Macbook Pro.

Hi Vicky! If your Macbook is an Intel base processor you should be able to use this RAM. I suggest that you check you Macbook to confirm compatibility. I know it could be difficult to select a good, not over price RAM. But this one work for me. -Check on Apple menu>About this Mac> and look for the info about memory upgrade. Also, is you know you Macbook S/N you could google it. I wish you the best of luck!

Thanks for your question! This RAM is fully compatible with that MacBook Pro model, and will upgrade it to 8 GB. Thanks!

This event surprised me, really. It is possible that the description of non-compatibility with Mac is made by mistake by the seller. If it were not intended for my MacBook Pro 13" late 2011 version, I would have not purchased the items. But the tandem 16GB DDR3 work fine with my computer. Just to make sure, I did re-check MacBook's System information, the memory is 16GB. And of course the improvement in speed and the number of simultaneous pages opened is observed, although I do not have the metrics. Just to be sure, do call the seller first and negotiate for a guarantee of refund for return - maybe you can get it before ordering. Also check the description of the memory cards in your system.

It works fine on my late 2011 MBP and 2010 uses the same memory based on its specifications. My assumption is that it will work. Worst case scenario - return memory to Amazon.

I have a MacBook Pro mid-2010 version, also upgraded to mavericks. I bought and installed this memory end of December. No problems at all, works great, huge improvement in speed. Even though official manual says it can only handle 4gb don't believe it. I also switched out hard drive for a SSD which made an even bigger difference in overall speed than the memory.

I bought these memories to use on my iMac 21 Late 2013 and worked perfectly. This memories are faster (1600 Mhz) that you have on MacBook Pro (1033 Mhz), so I guess that could work (the memories works with the maximum speed that Mac support). In the memory packaging says that works with any MacBook Pro 2011 or newer.

Well, it worked for me. I have 2008 imac. I ordered 4gb memory(2 chips). I pulled old memory out n inserted the new memory, one at a time. I turned on the computer n i could see the increased memory right away in drop down menu "about this mac."

I believe so. I have a MacBook Pro 13 inch from late 2011, and it works well. Best of luck to you.

The answer to one question determines your answer (answer only good for laptops and other systems using SODIMMS): In 'About this Mac' from the Apple Menu, there is a readout of your current memory. This memory should work if the line says anything regarding DDR2.My MacBook Pro came with 2GB of DDR2 running at 667 MHz, exactly the speed of this kit, but if yours is slower then the memory will work at the maximum the memory bus allows (up to 667 MHz). If your default memory is faster then this memory will slow your system down slightly (whether it will be noticeable depends upon how you use your system). In short, any Mac system that uses DDR2 SODIMMS should be able to use this memory.

I assume you are referring to the system RAM? If so, then yes it matters. RAM (Random Access Memory) allows the computer to run more programs and functions at the same time. I believe this particular Macbook Pro only goes up to 8GB of RAM. You can install the RAM yourself or have an Apple dealer install it for you. I don't think Amazon offers a different model with the installed 8GB of RAM. If so then go for it, assuming you have the cash for the purchase. I hope this helps.

The maximum RAM for your particular Macbook Pro model is 8GB (2 4gb of ram). You can also go to this website to find out more specs of your Macbook Pro. www.everymac.com Look up your Macbook Pro and it will let you know the max ram your Mac can hold. Good luck and hope I answered your question.
