Running 10.7.3, and I am following the recipe in notes on the top of the page, but changed the kext to ( (http://code.google.com/p/xnu-sleep-enabler/downloads/list) as per Horst recommendation. The kext installed and restarted fine, but can't get coolbooks to start. It says 'Coolbooks installation failed' before it launches, but the app still opens. However if I quit it, and launch it again, I get the error message (installation failed), and all my changes are gone. @Horst: Step by step how did you install it?

[ Twotimer]TwotimerAnonymous 28 Mar 2012 16:15
Why does everybody keep saying it works with Lion when in fact it doesn't, at least the way it did with SL?
Yes, you can install it, remove/add kexts, you might even see the frequency/voltage reports in the menubar. So it "sort of" works.
But in reality (and I believe it's not just in my case with 2007 Core2Duo MBP) it actually does a worse job than stock kexts. Battery life is worse (in my case 3h30m vs 4h20m, CoolBook vs Native), that's for sure.
CoolBook doesn't seem to be able to undervolt at lower frequencies. For example, when I set 600Mhz/0.7750V as the lowest combination, it still sticks at 800Mhz/0.850V. When idling on stock kexts, I notice 0.7-something-V in the istat sensors report.
The only point trying to use CB is when you constantly run your mac at max GhZ and just want it to run a bit cooler.

Coolbook is dead, and will be forever. AppleIntelCPUPowerManagementClient.kext now includes something called C and P states. Hackintosh users will be familiar with this (and actually are far far more knowledgeable about OSX than every Mac user due to having to tinker to get things working).
C and P states are for Intel's Speedstep and Turbo Boost independent over clocking features, much in the same way that Apple disabled smcFanController by constantly recalculating and resetting OSX's desired fan speed (and overriding the fan speed set by the program in seconds) C and P states erase the action carried out by CoolBook. Removing them is an option but that instantly breaks functionality with Intel i3/5/7 as they need them to scale power states correctly.
More importantly, if Intel roll out a new processor tomorrow, and the code for that CPU is added to a non-exisistant kernel extension (the one you swapped for sleep enabler) or the EFI (sleepenabler.kext is actually designed for hackintoshes) then you could be faced with kernel panics on startup that won't disappear with a reinstall unless you format your hard drive or CLI delete it in single user mode.

I can confirm that the sleep enabler kext provided in the link above also works with the latest Beta release of Lion (11C37). CoolBook also appears to be active on my MacBook Pro 13" 2010. However, battery life still seems to be suffering by about 20% compared to Snow Leopard.
[ Paul]PaulAnonymous 20 Aug 2011 12:28
I cannot get CoolBook working whatsoever on my Macbook Air (2008) under Lion. It runs but only clocks my CPU to 800Mhz. So I have about half the performance. It's pretty sad because I love Lion but I'm downgrading to Snow Leopard.

Hi, Cool Book works fine but if i close my laptop the and reopen it the display is black and I can't reactivate it … the only solution is to shut down and restart with the power button. Do you have a solution for that? I want to close my macbook and activate it without shutting it down ;) !

I just installed the developer release 10.7.2 and the steps and linked versions listed in the notes section work without a problem on my Gen 1 MBA.
[ Geoffrey]GeoffreyAnonymous 24 Aug 2011 15:55
With a clean installation of the latest developer preview (11C40) I'm getting some indication that CoolBook may in fact be throttling frequencies and voltages without the workaround solution. Although I received the same error message that the CoolBook driver wasn't installed, the controller is listed as a valid extension (CoolBook2.kext). Also, after having set reduced voltages under battery power and activating CoolBook, my estimated time remaining jumps by about an hour. Finally, if I slide the CPU Load bar all the way to the right, the reported frequencies and voltages match what I've set.
I've tried verifying the actual CPU voltages with iStat Menu, but am not sure if those readings are reliable, since even in Snow Leopard they don't vary much between on- and off-line usage.
Could it be that CoolBook throttling is active but the reported frequencies and voltages are somehow off? As I type this, my battery is at 84% and shows 7:45 hours remaining!

[ Blacky]BlackyAnonymous 27 Aug 2011 22:01
I can confirm that in OSX 10.7.2 Beta Build 11C37 coolbook runs even without workaround. Behaviour is the same it was before, though: Coolbook shows 0.925V consistently through all frequencies despite different settings and iStat Local voltages are still completely different.
Battery is down to 3:30 from 7 hours (!!) compared to Snow Leopard…………
[ Geoffrey]GeoffreyAnonymous 28 Aug 2011 02:58
Blacky, you need to update to 11C40 or 11C43. The Intel power management kernel extensions were improved with these builds, improving battery life for most models. I have CoolBook running on build 11C43 and am still trying to figure out if it's actually throttling. With the latest 10.7.2 Beta I no longer receive an error message that the CoolBook Controller didn't load on installation, and reported voltages and frequencies seem to match my settings more often than they did in earlier Lion builds.
[ Blacky]BlackyAnonymous 28 Aug 2011 16:02
Lol, well, I updated to 11C43 and screwed something up big time. I've downgraded back to Snow Leopard and got proper battery time again… Though it's more like 5+ hours, my bad, but still more than with Lion.
One interesting thing: I noticed how my lowest voltage is still at 0.925, the same behavior I had in Lion, which is too high. I can set all frequencies to 0.925 and it runs stable. I always thought this was a bug due to Lion, but it was the same in SL.
I dug a bit and manually changed the values in /System/Library/LaunchDaemons/se.coolbook.switcher.plist. The pairs are somehow merged:
"34314" is 798 MhZ / 0.8375 V
"34315" is 798 MhZ / 0.8500 V
"34316" is 798 MhZ / 0.8625 V
Lowering the last one / two digits by one lowers the voltage by 0.0125 V. Coolbook's table will show the right values, but the dropdown still doesn't allow the low voltages and you cannot test them. I however noticed that if the frequency changes, the voltage iStatMenus finds matches the settings :) I can only confirm that for SL, but it might be interesting for you guys, if you think your system can survive even lower voltages than what CoolBook allows.
[ Geoffrey]GeoffreyAnonymous 30 Aug 2011 06:37
You're right, Blacky. CoolBook cannot go below 0.925V on my system either, even though I've set 0.875V for the 798 MHz frequency.
In fact, after uninstalling CoolBook I noted via iStat Menu that the CPU voltage drops well below 0.925 V using Lion's built-in power management extensions. During light web browsing or other usage where lower frequencies are satisfactory, CoolBook is actually less efficient than Lion and should (for now) be avoided.
[ Blacky]BlackyAnonymous 30 Aug 2011 13:20
"CoolBook is actually less efficient than Lion and should (for now) be avoided."
I said so earlier, but it's possible that you get more performance with the "kinda broken" Coolbook than with Apple's default settings, so it might still be interesting for some. I had that in Starcraft 2: With Lions default settings I had like 2 fps with my 2010 Air under "heavy" load. With Coolbook the fps stayed at a playable rate (about 30 fps I guess) all the time. Lion probably reduces frequency a lot when overheating (which shouldnt happen under normal circumstances anyway). Battery is about the same with both, though. It's kinda ironic to use Coolbook to get extra performance and might not apply to anyone who doesn't play games.
[ Sascha]SaschaAnonymous 03 Sep 2011 08:34
I'm not sure, if everything works like it should. At least for me coolbook seems to work only when it's started. And even then, the idle temperature on my MacBook Air (Late 2010) is about 55° C. On Snow Leopard I always had a idle temperature of 40°C.
[ Bill]BillAnonymous 11 Sep 2011 18:34
After checking Coolbook with 10.7.1, I have to say… it doesn't make a whole lot of sense anymore.
With Coolbook, I get stutter while scrolling, possibly because the frequency doesn't ramp up fast enough, and top 5 hours of battery life on my Macbook Air regardless of what I do.
With Lion's default CPU power management, I can get up to 10 hours just typing text and with WIFI off. WIFI on marks about 5 hours of battery life on average, but still a lot better than with Coolbook where it's capped at 5 hours.
At least the procedure is now reversible, otherwise I would be kind of sad.

If you get stutter scrolling, make sure 'throttling level' is 'very high'.

[ Graham]GrahamAnonymous 29 Oct 2011 18:07
I'm not sure Lion's power management is better or more efficient than Coolbook as proposed by others. I have a late 2006 MBP. Under SL I ran Coolbook with a voltage throttle range from 0.95 to 1.10 across the full frequency range of my processor (2.33 GHz Core 2 Duo). I ran like this for almost 2 years with no problems and I saw huge benefits in terms of battery life and keeping the machine cooler. Under normal use, mail, ical, web browsing, iTunes, etc (all together) the processor's temp would hang around 58 degrees C and the fans would idle at just under 2K rpms. Now under Lion the CPU temp never drops below 78 degrees C, jumps up to 81 or 82 when I do almost anything, and so on. The fans run constantly at 6K+ rpms. My claim about Lion's power management inefficiency comes from this: the voltage to the processor never drops below 1.18 volts. I don't know that it actually throttles the voltage at all. I haven't watched the actually clock Hz in relation to voltage across the core yet, but I even when loading up the CPU with video processing of real time affects that I know are taxing the CPU, the voltage never changes. It's always 1.18 on the CPU and the GPU.
I'm so close to pulling the trigger on the hack to make coolbook work under Lion. I wonder, does anyone think that Lion's power management is actually doing anything good that I'm going to miss? Also, am I understanding this hack (work around) correctly? I'm essentially removing Lion's power management (the .kext file/extension) which allows coolbook to work in it's place. Yes?
[ Sascha148]Sascha148Anonymous 30 Oct 2011 11:35
Coolbook doesn't really work on lion. With the mentioned hack it seem to work, but this is just an illusion. The power management of coolbook isn't efficient on lion. For example: with Coolbook my CPU temp is about 40-45C on lowest voltage. Without coolbook the temp ist about 35-40C. However the temp under havy load is with coolbook lower than without it (because of lower voltage). Overall the battery life on lion is better without coolbook.
after weeks of testing I can say, that Lion runs defenetly better without Coolbook. The battery life and temps aren't as good as snow leopard + coolbook, but coolbook on lion just makes everything worse, because of bad power management in idle and normal load (office, internet etc).
[ Graham]GrahamAnonymous 02 Nov 2011 02:41
Update: fresh install seems to be solving my problems. Not saying it fixed coolbook, but the clean install of Lion, not an over the top upgrade, is running better than a clean install of SL. Time will tell, but maybe apple actually improved the kernel level power management. Volts to the CPU and gpu are lower and the temp and fans are way lower. Battery life is actually better than on SL. Get u that clean install. Upgrades don' t work on major release os
[ Serkan]SerkanAnonymous 09 Nov 2011 18:02
I disagree with Graham. Clean install of SL and Lion on my Macbook 3,1 have a temperature difference of 10 degrees! Even while not doing anything, Lion idles at 50 degrees, while SL idles at 40. With coolbook (which works on SL) I can work at 40-42 degrees (office stuff) and have the fan at 1800 all the time. Lion and coolbook gives 50+ degrees doing exactly the same thing, never mind the 70+ I get with full fans when doing anything more demanding (watching youtube or just starting photobooth is enough).

[ Geoffrey]GeoffreyAnonymous 18 Jan 2012 15:29
Josep
I think you're right. Just installed CoolBook on 10.7.3 Build 11D46 on a MacBook Pro 13" 2010 2.66 GHz model and voltages do appear to be reduced. However, I noted the amperage didn't drop below around 1000 A while on the battery, reducing battery life in idle use compared to the default Lion power management extensions. In Lion my amperage on idle drops to between 600 - 700 A, and the CPU voltage reads around 0.87 V according to iStatMenu.
Have you been able to extend battery life with CoolBook on a 10.7.3 system? I tried reinstalling the two AppleIntelCPUPowerManagement.kext but CoolBook no longer functioned properly, so they definitely need to be removed, but it still seems that Lion's idle power management is better without CoolBook.

[ Twotimer]TwotimerAnonymous 29 Jan 2012 10:31
It seems, indeed, that Lion's native kexts do a better job in low frequency area. It would still be nice to be able to undervolt the CPU around max clock frequencies. I know my CPU can work at zHg2.2|v5210.1#zHg2.2|v5210.1 instead of native zHg2.2|v5212.1#zHg2.2|v5212.1.

I installed the SleepEnabler.kext from the Link posted above (http://code.google.com/p/xnu-sleep-enabler/downloads/list) and it seems to run perfectly well under 10.7.3. (Macbook 3,1 Intel Core 2 Duo 2,2 Ghz)
