After detailed market research on foreign websites, I decided to purchase the package with the 2 RAM memories 2x4=8GB from Corsair to upgrade an older desktop iMac 24-inch, Early 2009 that had 2x2=4GB. I had prepared and watched videos about the installation on this model. The change required attention, but it was relatively easy. Upon starting the computer, the new chips were recognized properly, and as a result, the computer significantly improved in speed and performance. I was very satisfied on the first day of operation today, October 10, 2022.

For MacBook Pro mid 2009. Up until now (approximately two and a half months), it seems to be working without any issues.

It fits perfectly on a MacBook A1278 (Late 2008) model. It has a fast memory response on this laptop, according to a measurement I made with TechTool for Mac. From the market research I did, these are the cheapest reliable memories, with a similar price to those on eBay UK and DE.

They were installed on a MacBook pro 2009 and worked immediately and flawlessly.

They also worked perfectly on Acer Aspire 5738z 2009.

I bought the memory for a 2009 iMac that had been upgraded with an SSD, in order to open larger files without any problems or delays. Upon receiving it, I noticed that the iMac 2009 was not listed in the compatible models, however, the memory worked fine and the machine ran heavier projects better.

I had been seeing them for a while and finally bought them for 45 euros, for an iMac 21.5 late 2009. Although this specific model was not listed as compatible on the packaging, they were recognized and function properly.

Excellent choice for the mac! I bought them for my macbook pro and they work very well without any problems and significantly improved the speed of my computer! Reliable and affordable!
