That means, if you simply trash the app and think the removal is done, you’re wrong. Additionally, some apps may create supporting files, caches, login files scattering around the system directory. General knowledge: Once installed, an app is typically stored in the /Applications directory, and the user preferences for how the app is configured are stored in ~/Library/Preferences directory. If you have no clue how to do it right, or have difficulty in getting rid of smcFanControl 2.6, the removal solutions provided in the post could be helpful. This page is about how to properly and thoroughly uninstall smcFanControl 2.6 from Mac. Removing applications on Mac is pretty straightforward for experienced users yet may be unfamiliar to newbies. Peace.Perfect Solutions to Uninstall smcFanControl 2.6 for Mac Now that I finally have what I thought I was getting when I bought the MacBook Pro, this should be the last I’ll have to say on the subject of temperature control and fan noise. When that taxing installation procedure was over, I set the fan speed back to 1000 rpm. I used smcFanControl to raise the minimum speed much higher manually, which had the desired result. Shades of the past: yesterday I was reinstalling the iPhone SDK as part of a long battle (probably not to be related here) to be able to test my in-development iPhone app on an iPod Touch, when I noticed the smcFanControl temperature reading said 90° C, while the fans were still whirring away at less than 2000 rpm. Having smcControl running enables me to step in to raise the fan speed if necessary. I used it to set the minimum speed back to 1000 rpm, down from the Fan Control minimum of 1600 rpm I’d been enduring. In order to have a way of monitoring temperature and fan speed I went back to running smcFanControl, a program that only allows one to set the minimum fan speed. Here is the rest of the procedure: remove the following files and folders (both on your start disk)- /Library/StartupItems/FanControlDaemon and /Library/PreferencePanes/Fan Control.prefPane. This is fortunately not true, but the folks that make Fan Control should probably do a better job of letting people know how to completely uninstall it. I saw one unfortunate on MacUpdate warning people not to install Fan Control because it permanently changes the fan settings. Why not get rid of Fan Control? Removing it from the System Preferences Panel wasn’t hard (Ctrl-click and make selection), but this merely put the fan speed versus temperature profile out of my control, while leaving the last one set by Fan Control in effect. The fans on my machine, even though one of them was relatively new, having been replaced under AppleCare when my original hard drive croaked ( Fatal But Survivable: A Hard Drive Transplant Story), seemed to have gotten noisier over time, from overuse I suppose, so they were annoying me more. I can imagine Steve telling the engineers to get rid of that fan noise on the MacBook Pro, or else. Word was that it was needed to prevent premature death of the convectively cooled Mac. I remember buying a third-party fan that sat on top of my first Mac, the mighty one-megabyte-RAM Macintosh Plus. It may seem funny that Apple would have such high operating voltages coupled with such puny fan cooling but I think we have reason to believe that Steve Jobs hates fan noise (I’m with you there, Steve), perhaps beyond reason. This was not a solution for sustained operation at the highest default voltage used when the cpu was running at maximum speed, but I think it did keep things cooler than what Apple’s normal fan speed algorithm did. This allowed me to set the minimum temperature at which the fan speed would start ramping up and the rate at which it would increase with temperature. In my earlier efforts to control temperature I had installed a System Preferences utility called Fan Control. After a couple of weeks of stress-free lower temperatures, I realized that the previously necessary evil of the constant droning of the MacBook Pro’s cooling fans was no longer necessary. I can report that I have encountered neither high temperatures nor computer instability since adjusting voltages lower with CoolBook. A similar program (RMclock) is available for Windows. A great little piece of software called CoolBook enables one to do that on the Mac. The solution turned out to be undervolting-setting cpu operating voltages at values (determined by experiment) below the overly conservative ones set at the factory. See “What a Relief! MacBook Pro Overheating Problem Cured-Really” and “Can’t Boil Water With Vista on My MacBook Pro Anymore” for the details. This will be a brief coda to a couple of recent posts in which I related how I finally solved an ever-worsening (OS changes?) problem of overheating on my first generation MacBook Pro.
