NVRAM corruption is fairly uncommon, but if your Mac seems to take forever to figure out the correct boot disc, starts up with the wrong screen resolution, or suffers from weird audio problems (like thereР Р†Р вЂљРІвЂћСћs no sound whatsoever or the menu barР Р†Р вЂљРІвЂћСћs volume control is grayed out), a reset of the NVRAM might help-and itР Р†Р вЂљРІвЂћСћs quick and harmless. NVRAM serves approximately the same purpose as PRAM, but instead of storing a dozen or more pieces of information, it now contains just a few: your selected startup disk, speaker volume, screen resolution, time zone, and-if your Mac has crashed recently-details of the last kernel panic. Modern Macs no longer use PRAM they instead use something called NVRAM (NV for non-volatile). So you could press a key sequence at startup to reset (or Р Р†Р вЂљРЎС™zapР Р†Р вЂљРЎСљ) the PRAM, returning it to default, factory values. If the values in this memory got out of whack for one reason or another, your Mac might not start up correctly or might exhibit any of numerous odd behaviors afterward. The P in PRAM stood for Р Р†Р вЂљРЎС™parameterР Р†Р вЂљРЎСљ (the RAM was just RAM-random access memory), and it referred to a small amount of special, battery-backed memory in every Mac that stored information the computer needed before it loaded the operating system. SmcFanControl won't allow you to set the fan speed lower than Apple's default, so there shouldn't be any risk from using this app.Back in the day, the standard list of quick fixes for random Mac ailments always included clearing the PRAM.

I've been using it to increase the fan speed when I have the machine on my lap, and reduce it again when it returns to the desk.

It's important to note that smcFanControl is just an app - it doesn't install any components (unless you want it to run at startup). But in exchange for a cooler lap, I think it's worth it. Perhaps slightly reduced battery life, and a bit more wear and tear on the fan components. The downsides? More fan noise, obviously - although 3,000rpm was fine for my ears (though I probably wouldn't use that setting in a library). Perhaps if you're wearing noise a cancelling headset it would be bearable. but I was having trouble enjoying it, thanks to the 747 that seemed to be landing nearby. When I set the fan to max speed, I saw an even nicer temperature drop. Later today, I hope to get some more empirical data through a USB temperature probe. Using smcFanControl, I upped the speed to 3,000rpm, and saw a notable (two to four degrees Celsius) temperature drop.

But on my lap, it gets just a bit too warm. It works with the MacBook, MacBook Pro, and Intel-powered minis, and it works well.Р вЂќР вЂћpple sets the fan's speed at 1,500rpm, and this works well when I have the machine on the desk. As seen in the picture at left, this simple app gives you a slider to set the minimum speed for your laptop's fan(s). While I can't do anything about the first problem, thanks to smcFanControl, the second issue is now completely within my control. The only two things I'm disappointed in are the size (I love the 12' form factor) and the high case temperature (especially in the bottom left corner). Generally, I've been thrilled with the MacBook's performance, despite having to send it back to repair a way-too-warm power adapter (the repairs were successful). The price and performance of the MacBook struck a sweet spot with me, and I purchased one of the first black units to show up in the Portland area (I waited to see them in person so I could judge the reflective screen's performance for myself). When the MacBooks were announced, I made my purchase decision relatively quickly - I wanted something faster than my PowerBook G4, but didn't want to spend $2K+ for a MacBook Pro.
