    So I've been using this MacBook for many years now, and it's been a great machine. I recently decided to upgrade the RAM again from 2 GB to 4GB, even though I had read that it will only use 3GB max. I installed Lion and I wasn't happy with the performance I was getting out of it with 2GB.

    I installed the 4 GB and was surprised when it showed me 4GB in the System Profiler. So I thought maybe it is going to use all 4GB and all that stuff I read was false. So I'm a bit confused here, I go into Activity Monitor and check the RAM usage and it says 3GB.

    That's kind of disappointing that it really does max out at 3 GB, so 1 GB just goes to waste. Is there a way to make the OS recognize and use the remaining 1GB?

    No, it's a hardware limitation.
