Yes you can use a Samsung 850 EVO 2.5" SSD in your system swapping out your current HD. Follow this IFIXIT guide: MacBook Pro 13" Unibody Late 2011 Hard Drive Replacement

To make this easy get either a USB or FireWire (being faster) external case to hold your new SSD so you can prep it up.

Next you'll want to download from the App store the OS installer.

First you'll want to use Disk Utility to create a GUID partition map and a Mac OS Extended (Journaled) partition on your new SSD. Now run the OS installer and install the OS onto your new SSD. At the end of the OS install process the installer will ask you if you want to migrate your user accounts, apps & data over point to your current HD and all of your stuff will be copied over. The last step is to swap out your drives and thats it!

Two things you should do before you start:

- Make sure your systems firmware is up to date. Follow this Apple T/N to check: About EFI and SMC firmware updates for Intel-based Mac computers If you have something newer thats works to.

- A common issue with this series is the HD SATA cable breaking down and if you have a SATA II (3.0 Gb/s) drive currently in your system the cable may not support the faster SATA III (6.0 Gb/s) SSD you're putting in. I would recommend replacing it at the same time you put the SSD in. Here's what you need: MacBook Pro 13" Unibody (Mid 2012) Hard Drive Cable - Apple P/N: 923-0104

Yes, you can use it.

All SATA based systems can support a SATA SSD. The only issue you face is the systems SATA I/O speed and the speed of the SSD. In this case the Samsung 850 EVO SSD is an auto sense drive so it will match the systems SATA port's I/O speed! Not all SSD's do this so if you have a slower I/O speed system i.e. SATA II (3.0 Gb/s) a newer fixed speed drive i.e. SATA III (6.0 Gb/s) won't work.

Bottomline: Review the drives spec sheet to make sure it supports the SATA speed of your system. As an example Samsung 850 EVO spec sheet Note the Interface line, what ever drive you get needs to support what your system uses.


Thank you Dan your answer was great information and help for my future update on Macbook Pro mid 2010 15". hope I wont face any system errors as many people specify in the other threads.

cheers and thank you again.
