If Crucial doesn't have memory for your model Mac, then try OWC.

@Rudegar is absolutely correct that Macs are very picky about the memory they use. Do not purchase memory based on technical specifications (even when purchased from Crucial or OWC) because there are a lot of technical specifications which Apple does not publish which are critical for compatibility. Make sure to use the tools on their respective websites to identify the correct memory for your Mac...make sure to only purchase the exact part numbers listed as compatible. With Crucial, the memory will be specifically listed as "Mac Compatible" or "For Mac" on the website and should also show on the plastic packaging the memory ships in.

macs are pretty picky when it comes to memory modules, usually it's best to go to DRAM, Solid State Drive (SSD) & Memory Upgrades | Crucial.com

and choose the mac model then they list the modules and configurations they have tested and can verify to work
