Thanks to a few Youtube reviews, I selected the 850 EVO (250) for my Macbook Pro (2013). For those who are on the fence, I would recommend running a read/write speed test using an app like blackmagic via the apple app store. My original rating was roughly 25MBs write and 50MBs read, with the standard 500GB HDD. I used a simple SATA adapter cloning kit for under $20 to connect the 2.5 SSD to my MAC via USB. Once you connect the drive, the system disk utility launches and you can rename and partition the SSD- easy. I used the Carbon Copy Cloner trial version cloning software after i partitioned the drive and transferred all data via cloning utility. The transfer took less than 15 minutes and verified successful transfer via disk utility. Once done, I powered off and removed the back case of the Macbook- removed the four screws that retained the HHD and slipped the SATA connector off. I connected the new SSD via the SATA connector and replaced all retaining screws (after removing the hex screws from the HHD, I placed them on the new SSD). Upon powering back up, there was a slight delay but once done- perfect. My speeds boosted to about 330MBs write and over 500MBs read (**disclaimer** this number will vary based on what you have running while conducting the test). No problems as of this post, apps launch much faster and you will be amazed at how quick the OS launches after you power up or log-in. Great purchase for great price, speedy delivery and with the use of simple cables- you will be happy Im sure. Leave me a msg if you have a question.
