Would Samsung 850 Pro would work in a Macbook Pro Mid 2010??

Any Iuck with 850 evo?

I have the 850 Evo Sata 3 on the way and hope it works out for an upgrade on mid 2010 15" MBP i5 2.4 Sata 2.

Does anyone know if there is a way to convert a Sata 2 port to Sata 3? Maybe that would fry some stuff lolz? I know Sata 3 are supposed to be compatible with Sata 1,2 but hoping there is some hack or workaround to somehow get the 6gbps. Because better is better..

Thanks in advance!

Yes, as a matter of fact it works beautifully. Been using mine for a month now and no problems.

OWC (macsales.com) and Crucial sell SSDs that have fewer issues. My 2 year old Crucial has run without issue in my 2011 MBP. Both companies do claim full mac compatibility. But some Samsungs have been reported to work without issue.

The system has its own limits for SATA speed. The drives can negotiate down in speed, but the computer has its design limits which cannot be exceeded.

I hadn't tried this SSD with TRIM enabled and hoped your experience would hold for me as well. It didn't. Install (on a USB adapter) crashed shortly after moving the SSD to the internal SATA connection. Seemed to be running okay (for an hour or so) until I applied a software update then everything went into the weeds again with a slow boot ending in an abrupt power-down. Oddly this time the disk seems fine when re-attached via USB; I couldn't find the typical lost+found directory full of trashed files. Different than my last experience but still not a path forward. Hope you're having better luck than I.

Several people report the old drive works with the old internal SATA cable, but new drives do not like the old SATA cable. This can be fixed by replacing the internal SATA cable. These "cables" are more like flexible circuit boards so are finicky and can be fragile.

Hi, Desmond!

Any update regarding your post in December 2015? Does El Capitan run stable on Samsung 850 EVO?

HI All, I realise this is a MBP post but have a 11.1 iMac late 2009 that i have upgraded the HD with a Samsung Pro 850 before i looked at doing my MBP.

I have had a few install issues with it taking several attempts as it would install from USB then hang in the boot screen with the startup line about 2/3rds across.

I managed to get a clean install ofEl Capitan installed and running for about a month very nicely then things started happening, for no reason the screen would freeze but the mouse would continue to move, this got progressively worse till it happened about 3 times a day then reboots would not work.

I found an article on KEXT files and the permissions in El Cap and noted my logitech control centre was one culprit and removed the KEXT to an unsupported folder and used Apple mouse and keyboards again BUT a day later the same issue.

I am wondering do Samsung 850's have issues with older Mac's or Mac's in general ? Tonight after 5 attempts i have managed to get a clean install of Yosemite back onto the system with the Samsung still installed to test and see if its an issue with El Cap and security Kext extensions and third party items not being supported, or if the SSD comes up with any errors.

Disk Utility and first aid did not find any errors on scans!

Hope this helps and any one who has other info i would be interested in hearing from, I may try Samsung about any possible firmware support ??

Cheers Tim

Thanks for the suggestion, but I had already replaced the internal SATA cable with no change in luck.

Yesterday I finally gave up on the Samsung 850 EVO and installed an ADATA SP550 instead. No issues at all with this drive, so either I have a bad 850 EVO (although it seems to work fine in other systems I have tried it in) or there is an incompatibility lurking within my vintage of MacBook Pro (MacBookPro7,1).

Getting on with my life now.

Same issue seen here on Late 2011 Macbook pro and 1TB 850 Pro and 850 Evo, Must be a compatibility issue .. 840 seems more stable
