Why does memory usage increase after RAM upgrade
I upgraded my MBP RAM from 4GB to 8GB. I'm not running any additional applications, so I expected machine's RAM usage to remain the same as it was before upgrade.
However, my RAM usage has increased to 4.6 GB. Why does my machine need more RAM now for the same lot of programs?
