Have I maxed out my OS?

13" Mid-2007 MacBook

SSD boot drive

That's what I have and I'd like to update/upgrade OS, but I think I am not allowed anything beyond 10.7.5.

Am I limited and is it due to age/model of the machine?

10.7.5 is the latest OS X version supported by your MacBook.

You can find complete specs for your MacBook on EveryMac.com.

I asked the same question today

I was told 10.7.5 (lion) is the limit. But, you can add an extra memory for a total of 3 GB. Someone please correct me if I'm wrong...

You are correct - your Macbook will not use more than 3GB of RAM installed.
You CAN go to 2 x 2GB for a total of 4 GB physically installed, where you might measure a small increase in performance because of a matched pair of RAM sticks - but the system will only use 3GB of that. Speed increase from a matched pair is probably not noticeable in real world use - but is a choice for you, too. I'm sure you already have good speed from your SSD. 3GB would be your last enhancement for your Macbook.

A good explanation of why there is a 3GB limit is found here: http://www.everymac.com/systems/apple/macbook_pro/faq/macbook-pro-core-2-duo-3-gb-memory-limitation-details.html
