Works perfectly well. I have a dual processor MDD, running Leopard, nap mode enabled, uptime three days including some real work.

The system temperature right now is 109.4F, instead of the 137F it would generally be without nap mode. No performance penalty, much quieter operation, less heat stress on the components, and wonder of wonders, I get to use the new Xcode. No regrets.

Here's what I make of the previous comment: I think the previous poster had a single processor machine, that the Hardware panel running under Leopard can't determine whether the machine is in dual or single processor mode so it leaves the dual processor mode radio button set by default when it opens, then when it closes it finds that radio button set, and so it sets dual processor mode, then that lead to weirdness on that person's single processor machine.

Long story short, the working theory is that if someone with a single processor machine uses the script given above which explicitly sets single processor mode, it ought to be fine.

Anyone with a single processor machine having weirdness ensure?
