CoolBook lets you monitor CPU frequency, voltage, and temperature.
Registered users may set voltage and frequency manually. This can dramatically reduce heat dissipation and fan noise.
Use your MacBook with full performance without a battery installed.
Storing your battery properly when not used will reduce battery aging.

It looks like I am not the only one that could never get a response back from the developer.
- Frustrated!

Yes, I recommend this app if you know what you are doing. Don't expect any help or support from the developer. You are on your own.

It prevents my MBA-A from climbing up to 100C, keeping it cool down to 75C max with power savings and hence battery savings such that after 650+ cycles still has 88% health. (The 12% loss is probably due to me keeping it plugged in AC all the time).
I can comfortably keep it on my lap and even reduce the temps further down if I find it too much on my legs. It extends the battery range very well; it IS, without a doubt, the BEST $10 I have spent on anything to do with an Apple.
As for all those whiners complaining about the TOS - Harden up, princesses.
You pay for a $1000+ machine that rocks yet complain about a $10 app that literally saves it from losing a core; preventing it from becoming half of what it's worth; get real.
The pitiful $10 asked for this app is basically a donation! It is really worth $50 for what it does. The TOS is there so that it doesn't cost $50; the licensing server prevents pirates from ripping it off.
Kudos to the Marcus (the developer) for sticking to the TOS. I've asked for help before on some licensing problems when updating & purchasing another license for my MBP 2007 and I've received it.
Marcus is likely a one-man team - come-on, he's got a life too you know! Sometimes what you need to do is RTFM. There are countless webpages floating around that will help you get there.
I would probably only offer a couple of suggestions:
1- Make the app work in such a way so that the finding of VF pairs is almost automatic; with the user only needing to HARD-RESET to continue the next test when the kernel panics.
2- Please make it work for OS X LION. My MBA-A is DYING as I speak (and typing this). Oh how good Coolbook is - I'd pay $5 in a sneeze to get it working again. Please let me know mate, I know you're probably hard at work finding a way... Else it's gonna be a new MBA for me. (See? $5 can potentially save me $1000)

BTW, my MBA-A is not acting like before; it's not shutting down a core when it heats up. Instead, it heats up until it freakn' shuts down from the heating !!
Any ideas what to do until this developer answers my email or updates the app ??

This latest version still lists incorrect CPU speeds on both, my MacBook2,1,[Merom] and my MacBookPro4,1.[Penryn]. Both units running 10.6.6
Hopefully these older Intel units will continue to receive support. I'd hate to loose the functionality that Coolbook provides. My 2006 MacBook Battery still holds a 3.5 Hr. charge after 5 years of continuous [24/7] runtime, thanks to CoolBook.

Do you mean that the product is too expensive? Is half a star for pricing, or performance?

When I bought the license in 2006, the terms simply said "for one computer", which isn't too unusual and is usually interpreted to mean some form of "one computer at a time".
Since then, the author has retroactively changed the license terms so that only the serial number of the originally registered machine is accepted. He now refuses to allow me to register the program on a different machine!
Avoid!

The process of setting voltages could be automatic ( I don't know if its possible). Anyway, as I have mentioned before : I love this app, i have underclocked three computers and its working great.

The licensing terms are terrible, especially for a small developer.
Too bad.

"This license will work with one unique computer only. The customer is allowed to reset the license once. This in the event of broken and repaired computer.
It is not possible to transfer the license to a new computer."
This makes Adobe and their much criticised activation terms of their Creative Suite look like Santa Claus.
I sympathise will developers who put a lot of time and effort into writing and supporting applications and wish to make some money from it without it being being posted to every torrent site imaginable. This developer, IMHO, simply goes to far though and appears to view everyone as a potential copyright infringer. Therefore I, for one, will not be parting with my cash under these terms.

I understand your frustration. After I started using Coolbook I changed my Mac quite a few times. The first time I changed, I was shocked that the Developer told me that I'd have to purchase a new license for a new Laptop.
Still, after having payed for over 5 Coolbook Licenses I don't look back. It's 10 bucks and it really does what it promises. I see it like a hardware add-on. A better Fan?
Anyway, I just upgraded to an i5 and I'm eagerly awaiting support from the Developer. Please update your fantastic app!

Could you explain how did you make it work in Lion?
Thanks in advance
