Very nice upgrade to my 2011 MacBook Pro

Installed this in my 15-inch, Early 2011 MacBook Pro recently and it seems to work very well. Performance is very quick and a huge improvement over the old HDD. I like it a lot so far. Installation is really easy if you are comfortable opening up your Mac, and I think most anyone with just a little ability at these things can do it.

Thanks for the great upgrade! The packaging came, was a tad later than the projected date, but is working like a charm. High quality, works fine in a mac. :)

Thanks again!

I did a clean El Capitan install on my Macbook Pro Early 2011 upgraded with the Crucial SSD. Sure does this clean install have a lot to do with the current performance, but my laptop now runs like brand new! I'm glad I decided to upgrade my laptop instead of getting a new one.
The Crucial BX100 has been working smoothly since I installed a week ago. I can tell there is HUGE difference compared to the old HD drive. The laptop boots in few seconds, and I've never seen the beach ball again. All apps respond immediately.
To be fair, I couldn't surely say that the Crucial in particular is responsible for my happiness, it probably is the HD to SSD experience. But still I think it deserves the 5 stars because this product in particular has worked perfect for me. I can't compare to other SSDs though.

I have a late 2008 unibody macbook pro that only had 2 gb ram. Decided to upgrade it without spending so much. These were easy to install and noticed an improvement right away. OS X mavericks definitely works better with more RAM.

It worked perfectly with my macbook pro early 2011. I can see a huge change with it, and was able to update my mavericks to MacOs Sierra (which is nicer). The shipment was on time and excellent.

RAM upgrade has brought new life to my MacBook Pro Mid 2009 15".  I doubled the system RAM from 4GB to 8GB. I wish I would've done this sooner.

Upgraded my mid 2009 15 inch MacBook pro with the Crucial MX200 SATA. It is like a new computer. I can boot up OS X El Capitan in under 10 seconds whereas before it would take over a minute. It has made an amazing difference. Next thing I will do is upgrade to 8 gb of RAM from Crucial. I highly recommended replacing the hard drive with SSD. It will transform an old mac. Install was super easy on my MacBook pro. I will point out that if you plan on using a bootable USB to install the OS, then you will have to first format the crucial drive using the disk utility. If you do not do this, it will not show up when you are asked to pick a location to install the OS. The Disk utility comes up as an option from the bootable OS. Pick the crucial drive and then erase. Then you can select the format that is required (it was automatically selected for me). Then it will show up when you click on the install OS option when you boot up. If I had known this before I started, I think the entire process would have taken about 15 minutes. Making a bootable OS on USB is also super easy though you have to have a thumb drive that is 8 gb and you will have to copy and paste a command into terminal. There are plenty of internet resources on how to do this. The option of course is copying the image from the current hard drive onto the SSD.

Ijust switched over from PC to Mac and have had to do so on a budget, so after buying a manufacturer refurbished mid 2012 MacBook Pro and getting the memory upgrade, the solid state drive was next and then AppleCare. This was consistently reviewed as the best SSD on the market and thus I didn't mind paying a few bucks extra since, with a 10 year warranty, Im hoping that I can use this later on in whatever subsequent computers I end up buying. Some tests simulated 75 years of usage for these drives, which is laughably beyond the 3-6 years Ive gotten out of traditional mechanical hard drives.

The install was easy enough as the only time-consuming part of the process was the data transfer which I performed with a USB to SATA cable from Frys (electronics retailer in SoCal; Amazons cable took forever to arrive) along with the free version of the Super Duper software, after wiping the new drive with MacOSs Disk Utility. The drive initially took a few seconds for the Mac to recognize, but after configuring the SSD as the correct boot drive (computer seemed to be looking for the old drive) the machine boots from off to usable desktop in 15-20 seconds.  Most of the software, even bulky programs like iTunes and Microsoft Outlook, loads instantly. I still get the spinning beach ball on occasion, but, otherwise, for a mid 2012 MacBook running Sierra in 2016, the memory upgrade and SSD give me the feeling of running a genuinely brand new, late model computer.

The only issues I had were identifying the SSD as the boot drive as mentioned above, enabling TRIM, and transferring my Microsoft Office license.  The boot drive settings I figured out under system preferences, TRIM I was able to enable by Googling around for the correct machine code (dont need extra software), and Office took a few calls and online chat sessions to figure out, but thats not Samsungs fault.  Overall this is a fantastic drive that I highly recommend.  The performance boost is incredible and what I also appreciate is that the computer now has no moving parts on the inside so thats one less thing to have to worry about (besides the laptop screen) should I drop the thing when traveling.  The only big issue I had was the price per gig, as $200 for 512 gigs doesnt leave much wiggle room space-wise and $400 for 1 TB was beyond my price range.  That said, I was able to buy an enclosure for the old drive which I now use for backups along with an old 1 TB USB drive for larger files.  I wouldve been happier with 750 gigs for this price, but the 850 PRO and its 10 year warranty seems designed for heavier users while the EVO and its 5 year warranty is more for home users.

I upgraded the RAM on my own. This is for Mid-2012 13" MacBook Pro. The process was so easy. It's a little nerve wrecking taking apart such an expensive machine but it's worth it. Full process took under 5 minutes. The bottom RAM was a little tough to get out and takes a little muscling so don't be overly cautious.

Recommend to anyone looking for a bump in performance!

My 13" MacBook Pro with an I7 processor had become slow.  I watched a YouTube video on how to do this install, reinstall the OS X, and then migrate all my programs (Using the OS Migration Assistant) and settings from my Time Machine backup.  The install took 15 minutes, the restore from Time Machine took much longer.  The system now is lightening fast again--faster than it was when it was new.  Bootup time is about 20 seconds, and every program launches almost instantly.  This slight investment (plus upgrading from 4GB of RAM to 8GB of RAM cost less than $450), and saved me $2000 on a new machine.  I am very sure a new machine would not run any faster.  I would guess that I will get at least another two years out of this two year old computer.

I bought two of these, one for a late 2011 15" MacBook Pro with a 2.4 GHz quad core i7 and 16 GB of RAM as well as for a mid 2009 13" MacBook Pro with a 2.26 GHz Core 2 Duo and 8 GB of RAM. Both machines are incredibly fast, boot up within seconds, and make my computers feel like brand new again. My 15" is essentially a desktop replacement and can render and export 1080p videos from Final Cut and Premiere Pro in just minutes. Great value!

Installed it on my 2011 MacBook Pro 13", which was running off 4GB. Very noticeable improvement after upgrading to 16GB.
