How do I know my MacBook Pro's model?
I need to change my MacBook Pro 13'mid 2009 battery, and for that I need my computers model to make sure I buy the right one.
The bottom of my computer, for some reason, only has the serial number, not the model number ( the one that starts with "A117...etc)
When I go to "about this mac" the only answer I get is that the model ID is "MacBook Pro5,5"
How do I know what model do I have?
