Question 1

Is this compatible with a late 2009 ubibody style macbook?

Accepted Answer

Yes. I use these in a 2010 MBP, and the polycarb unibody macbook uses the same memory. However, keep in mind that Apple officially supports a maximum of 4 GB of RAM, but third-parties have determined that it actually supports 8 GB of RAM running OS X 10.7.5 "Lion" or higher and the latest EFI update. SO make sure you're up to date.

Question 2

Why, for mac’s only? Thou I do doubt that’s the case. It’s been my experience that memory could work on any machine depending if the specs match the computer. What I want to know is what makes this memory a mac only Memory?

Accepted Answer

My guess is something with the hardware assignment of addresses and the specification standard used. It's done the "correct" (probably more expensive) way in the Mac memory. I read reviews from the equivalent "windows/any pc" memory and Mac users who bought that had issues. The G.Skill tech support then specifically pointed to this product which is Mac compatible.

Question 3

I have a white Macbook (not Pro) I believe it's a 2009 late model - some of the specs for memory are confusing as well as the previous questions/answers - at least to me. If I purchase this particular kit is it overloading the memory? The specs on the Macbook say "...up to 4gb" but that seems to be per slot - I'm not sure.  Sorry to be such a doofus, but I don't want to have issues.  It currently has 4gb (2x2gb).  From what I've read it looks as tho I can upgrade to 8gb.  Thanks for clearing it up for me!

Accepted Answer

Tha max limit on that mac as long as OS X is 10.6.8 or higher, it will accept up to 8 gigs of ram. This G.skill kit which should be 1066mhz ram speed is sufficient.

Question 4

I have a late2009 iMAC 21.5", will this memory work?

Accepted Answer

It should work it matches the specs for the Late 2009 iMac, I purchased this RAM for my 2009 Macbook Pro, and it works wonderfully.

Question 5

Is this memory Non-ECC, Unbuffered?

Accepted Answer

sorry, I don't know! IT guy told me what to buy

Question 6

Is that work to iMac 24" (Early 2009)?

Accepted Answer

It will work as long as the speed and type is correct for your iMac. I have it in my 2010 Macbook Pro.
