comment Temporarily disabling RAM to mimic a lower spec machine?
But the question was, "Is there some way to temporarily disable RAM without physically removing the chip?", so this does not answer the question

-1, sorry... this is not a good comparison. Now, you have virtualized video drivers, virtualized I/O, and a small CPU performance hit. I love Virtualization, but if all you want to do is see how the system would perform with less RAM available this is not a good solution.

You can probably just dump all the calculations of the disk size and let dd fill up the whole disk: dd if=/dev/random of=/Volumes/RAM\ Disk/random.dat bs=1024k

comment Application eating ~840,000,000% of my CPU
When this happens, what does the top -u terminal command show? How about the output of loadavg ?

100% CPU usage is 100% of one core. So on a Mac Pro, 1200% means 12 cores at 100% usage. Note that a hyper threaded core can go to 200% if both threads are fully utilized. I am reasonably sure that the images shown in the screen captures here are a bug.

comment Are Macs vulnerable to the Bash shellshock bug?
These are irrelevant. Either of these, by their very nature, grant users access to run commands on the system, so if you have them enabled then it is your intention to allow users to run commands. The Shellshock bug is a means for users whom you didn't intend to be able to run commands to be able to do so, E.G. a user of the web server you run. So, your answer should say "Disable Web Sharing" (but that's just one thing to check)

comment Are Macs vulnerable to the Bash shellshock bug?
@JeffBurdges: regarding "Installation scripts usually use bash, creating privilege escalation risks", why would a malicious installation script need to use this exploit? If the user is installing a malicious installation script (a trojan horse) then the code wouldn't need to invoke this bug, it gets root anyway.
