hey guys, i've got a Mac Mini 2011 with 8GB of RAM here. it seems like every 30 minutes i need to use the 'purge' command in Terminal. does anyone know why this is the case? i keep running out of RAM. when i use Win7 i've got 4GB of RAM, but i never run out of it. i know Mavericks will address this issue, but what can i do in the mean time? thank you!
