8GB. You can find specs on all Apple products, including maximum RAM:
- By visiting EveryMac.com: Actual Maximum RAM
- By selecting your model on the Crucial Memory Advisor Tool to find RAM information
- By using Mactracker
- By entering your serial number here to find specs for your model.
(Be aware that some models can use more RAM than Apple shows. Check EveryMac to verify actual usable RAM.)
You can go up to 8GB of DDR3 RAM. Use something like the model checker on crucial.com - This will give you the RAM type/speed/pin count etc. It's a cheap time to buy this ram as well. Enjoy.
I normally visit crucial.com and drill down to your model. It will tell you the max memory and the type/speed to use. With that information, I shop around like Newegg and Amazon for good deals on the memory. Good luck.
GGJ has some good stuff with his link. Mostly if you run the permission verify/check via Disk Utility, that fixes most of the problem. Could even fix your speed problem. Give that a shot, its free and its quick.
