How do you check what resources are available in OS X? Such as RAM usage...
I found how to check Hard Drive free space, just not the resource area for RAM usage. <img src="graemlins/hmmm.gif" border="0" alt="[Hmmm]" />

The short answer:
The long answer:
RAM is handled very differently in Mac OS X than in previous versions of Mac OS. It is a *completely* different memory management system, in fact. Real memory, shared memory, and virtual memory are allocated, swapped around, and dumped dynamically by the system without any help from the user. That's why you don't have a memory section in the "show info" Finder window any more. You can watch these stats by using the terminal command "top" (which also shows CPU usage).
If you really want to learn more about the process, I suggest you read the <a href="

You can use the process viewer to see some of this stuff, but RAM usage fluctuates quite a bit since it's dynamically allocated.

I think you'd like this app, called AquaMon
It's a beautiful freeware Cocoa app that displays more system stats than you'd ever want transparently on your desktop.
Plus it's written by a really cool guy at Ars, who will add features and fix bugs overnight if you ask him on the boards!

df is a handy utility for seeing free disk space. Top should tell you about ram usage at the, um, top of the term window.
However, as SFX pointed out, this information is misleading and borders on useless.

if you understand how they work
. Shoot, you could say the information provided in "About This Mac" in Classic Mac OS was even more useless for someone that doesn't understand <a href="

That's why I gave the link to Siracusa's Ars article: to learn what these numbers mean.
