Question 1

Does this work with all Apple notebooks? I have a 15" Macbook Pro from 2010.

Accepted Answer

I don't know. I used mine in my iMac and it works great!

Question 2

will this fit my late model 2009 iMac 10.1 ?

Accepted Answer

yes it will i used it for same labtop

Question 3

Is this memory compatible with a 27" iMac - Late 2009 model?  Also, can I simply add this to the 4GB (2x2GB) already installed for a total of 12GB?

Accepted Answer

It's OK, but 12GB, might be a bit off. Check your iMac for your PC3 speed, but should be fine.You could if you have four slots available, but I highly doubt it unless you bought a high end Late 2009 model; look for your model number please.
