Crucial 8GB (2 x 4GB) DDR3 1066 (PC3 8500) Unbuffered Memory for Mac Model CT2K4G3S1067M

Pros: Works great in my mid-2009 MacBook pro. Nice performance bump going from 2 GB to 4 GB

Cons: None.

Overall Review: The very act of pulling off the back cover and inserting the RAM caused the hard drive cable to fail, which is a well known problem with this model MacBook pro due to faulty design of the cable itself. The cable is flimsy, poorly insulated and sharply bent in too many places. Had to wait a week for a replacement cable. Once the cable was replaced, the laptop has worked flawlessly with the new memory.

Pros: Worked right away. All 8GB are being recognized and utilized by the computer. Unfortunately I haven't owned it long enough to comment on reliability.

Cons: Nothing so far

Overall Review: I have read that some people were having trouble with their Macbook Unibody's not recognizing all 8GBs of memory. My computer is a Late 2008 Macbook 5,1, 2.4 GHz Intel Core 2 Duo, Unibody OS X 10.9.5 with the latest firmware update. So far no issues.

Pros: Packaged very well, arrived very quickly

Cons: I mistakenly ordered the wrong item.

Overall Review: Make sure you order the right item! I've been trying to request an RMA from Antonline for weeks now, and I've gotten no response.

Pros: I installed this ram into a mid-2010 MacBook Pro that came w/4GB of ram. Noticeable improvement in performance, frequent color wheel is now rare even w/several applications running.

Cons: None that I can think of.

Overall Review: I would recommend this product.

Pros: - it works exactly as it is supposed to

Cons: None.

Overall Review: Used this to upgrade a co-workers late 2008 Macbook Pro. It performs so much better with this upgrade. Definitely worth the price!

Pros: Worked as expected. Synology requires specific memory and this one worked.

Cons: None

Overall Review: Bought some "other" memory at a local electonics store that was the right type but had issues (chips on both sides or something similar) such that it wasn't recognized by my Synology DS1513+. Selected this model based on some forum reviews. Worked the charm.

Pros: Notice huge improvement in speed as I always open many applications in one go especially Logic Pro X.

Cons: No cons. Very good product!

Overall Review: I reside in Singapore and trust me that NewEgg price for this 2x4GB ram is almost the same as local price ($108 including express shipping). If you get this exact model from Sim Lim Square it's going to be much more expensive and sometimes you do not know whether the shop is trustable. Ordered item on Tuesday and arrived swiftly on Friday afternoon.

Pros: wORKED FOR ME!!!

Cons: NONE.
