However, it also has a bug (rare, but there nonetheless) that causes video corruption with h.264 video files under very specific circumstances, with the GeForce 9400M. High Sierra has a bunch of features that are missing in El Capitan, including HEIF and HEVC support, APFS support, and a much better version of Photos. I think they were just clearing it out, since I haven't seen it for sale there since. In my case I got a 8 GB kit of Transcend RAM just because I got it for US$35 in an Amazon.ca sale (sold by Amazon itself). I believe OWC has what you need for US$74 for the 2 x 4 GB = 8 GB kit, whereas Crucial has it for US$92. However, right now I think OWC is significantly cheaper than Crucial.

If Crucial is similarly priced, I'd recommend Crucial. They really just rebrand other RAM, but since they cater to Mac users and have a reasonable warranty, Mac users like OWC RAM.Ĭheck out the RAM prices from the various brands and compare the pricing. Crucial is the retail brand of Micron, one of the largest RAM chip manufacturers in the world. I think the actual hardware is more important than the supplier is this is to be a good reference thread for anyone pimping up an old MacBook Pro.Ĭrucial is a top tier brand. I'm based in Ireland, but happy to see recommendations for Should I stick with El Capitan as this is the last 'officially supported' OS for the MacBook Pro 2009? MSastre also suggests that replacing the battery is easily done. I've also been recommended the Samsung 850 EVO 250 GB 2.5 inch SSD. So, can anyone recommend the best SDD, RAM and battery please? I've already had recommendations (thanks to MSastre) for Crucial for both SSD and RAM.

I have a few recommendations from another thread, but I thought this topic deserved a separate thread in case anyone else is thinking of doing something similar. I'm also thinking about replacing the battery (current health is less than 50%). I want to upgrade the HDD to an SDD, and I'll put in as much RAM as possible (there are 2 RAM slots (see attached). I've decided to to upgrade it as much as possible (as per advice I've received on these forums) as it's very slow. I just got my hands on a MacBook Pro mid-2009 thats in very good condition.
