Adobe AE CS5.5 "Insufficient RAM, Multiprocessing disabled"

[MTLaw]

Hello,

I just recently finished building my Hackintosh. I have been working a lot with editing video in After Effects but when I try to do RAM preview with After Effects Multiprocessing I get an error saying "Insufficient RAM. Multiprocessing disabled." I don't know what the problem is nor how to fix it. Does anyone have any ideas?

Thank you!!!

You might be booting the 32-bit kernel instead of the 64-bit kernel. The 32-bit kernel limits applications to 4 GB of RAM each.

Go to /Extra in your hard drive and open org.Chameleon.boot.plist with TextEdit. Under <key>Kernel Flags</key>, make sure it doesn't say "arch=i386".
