Click anywhere on your Windows desktop when Parallels is running in full-screen mode. Press the 'Alt' and 'Ctrl' keys on your keyboard at the same time and immediately let go. This will remove your mouse cursor from the Microsoft virtual machine and allow you to access the Parallels menu bar. Here’s a quick tip to fix for those of you Mac users who are using Parallels 5 as the virtualization solution. Support came back to me with the following steps to fix the problem. First, quit Parallels if. A good third alternative, by the way, is to simply choose the option “Ask me what to do”, which means that every time it detects a new USB device, you’ll have the option of letting Parallels have it or let Mac OS X have it.

There’s been a number of complaints in forums about MacBook Air heat problems and fan noise or fan running constantly. What causes these heat issues? What’s the fix? Does it affect the i5 model as well as the more powerful i7?
This article addresses fan noise and heat issues with the current MacBook Air 2011 / 2012 models, released mid-July 2011.
Here’s a video a Mac Crazy user sent in of watching video online with his MacBook Air i5 13 inch. The fan is loud!

MacBook Air Fan Noise
First, lets start with a bit of background of why the MacBook Air get hot and why it has a fan. The MacBook Air has one fan inside it, at least in the late-2010 & mid-2011 models. The fan’s job is to keep the MacBook Air’s chips from overheating by pushing hot air out the exhaust port. The exhaust port is behind the keyword, at the screen hinge.
The MacBook Air fan runs constantly by design. The fan runs at or above a minimum speed while the MacBook Air is running. On my late-2010 MacBook Air 11 inch, the minimum speed is 2000 revolutions per minute (rpm).
At this minimum fan speed, during use, the fan can’t be heard by most people. If you put one ear to the keyboard, you can hear the fan. Some people, in a very quiet room, with very sensitive hearing, may be able to hear the fan at the minimum speed.
When the MacBook Air is busy it generates more heat. The fan then runs faster to keep the Mac cool. At higher speeds, you can easily hear the fan.
This is a normal cause of fan noise on the MacBook Air – MacBook Air is busy, fans are keeping it cool. Fan noise is like sweating – it’s a response to strenuous activity.
Examples of activities that make the MacBook Air busier are:
The room temperature will affect how fast the fan will need to run to keep the MacBook Air cool. In a hotter room, the fan will need to run faster.

If you have constant fan noise, and your MacBook Air is not doing heavier activities, your Mac’s System Management Controller (SMC) may be confused. You can fix this with a SMC reset.
MacBook Air Too Hot
The hottest temperature on the bottom of the case I’ve seen quoted in the press is 105F / 41C (AnandTech) and in the wild is 109F / 43C Difference between computer hardware and software. (thanks for commenting Corbin). This benchmark was running Half Life 2 Episode 2, which works both the main processor and the graphics processor – both of which generate heat. Both processors are on the same silicon chip in the new MacBook Air.
(If you have a higher MacBook Air 2012 / 2011 bottom case temperature, please take a screenshot and leave a comment below.)
If your MacBook Air is getting too hot, there are some possible fixes below.
Heat and Fan Noise: Just the MacBook Air i7, or MacBook Air i5 As Well?
The fan noise and heat issues are affecting the i5 MacBook Air as well. Complaints of the MacBook Air heating up, overheating and fan noise are not restricted to the Intel Core i7 MacBook Air. I’ve had a reader send in a video of his MacBook Air i5 with a loud fan.
MacBook Air Heat Issues and Fan Noise Causes
There are at least several possible causes for the MacBook Air high heat and noisy fan:
Cause #1: Software that Consistently Uses Processor
Software that is performing an activity that consistently uses can cause the MacBook Air to get very hot and the fans to run loudly. A few examples of heavy software are:
If you are doing sustained processor intensive work expect it to get warm or hot and for the fan to become audible or noisy. Using either the main processor (CPU) or graphics processor (GPU) generates heat.
In these cases that MacBook Air is usually performing normally. Some of the heat is dispersed to the case, so the case feels hot. https://ibgaonf.weebly.com/blog/spotify-will-not-download-offline. The fan speeds up pull cool are in and push hot air out of the MacBook Air.
Cause #2: Software in the Background Consistently Consuming CPU
Every application running in the background uses power and heats up the MacBook Air. If you use less battery, your MacBook Air gets less hot. If it gets less hot, it doesn’t have to use the fan. And on the way, you might double your battery life.

You can see how much power each app is drawing, use the free software coconutBattery. To help cool down your laptop, quit background apps or pause them using the 3rd party software App Tamer.
Note that it’s not just apps running in the background that consumes power. Other background services (often called daemons) can also consume power. Mostly these are pretty efficient, but for power users, it’s worth checking.
See my article “MacBook Air Battery Life” for more info on reducing power usage and making your Mac cooler and quieter.
Cause #3: Adobe Flash Consistently Using the Processor
Flash is software that can be installed as a plugin to most web browsers, such as Safari, FireFox & Opera. Google’s Chrome browser includes Flash. Flash is mainly used to include animated and video ads in web pages, to deliver web video and provide games in webpages. Flash is not uncommon for charting. It’s also often used for entires sites for big product launches, like Hollywood movies.
Flash tends to use a lot of CPU. Most people who use Flash aren’t professional programmers, they’re usually creatives. One poorly written banner ad can swallow an entire core of your MacBook Air’s processor.
While the latest versions of Flash do some hardware acceleration for video playback, Flash still uses considerably more CPU to play video than native video players like Quicktime X.
Consider if a Flash banner ads is not visible: it’s in other browser tab, your web browser is in the background while you’re in another app (e.g. Word), or the banner is in part of the webpage that isn’t showing in the browser window. The Flash portions of webpages continue to run and consume your processor and battery even when you can’t see them.
Mac Won't Let Me Quit Safari
Flash’s heavy use of CPU was running of the reasons Apple doesn’t include Flash on the iPhone or iPad, and why Flash doesn’t come preinstalled on the MacBook Air.
To minimize Flash’s grip on your processor, you have a few alternatives:
Some of these techniques can be combined. For example ClickToPlugin plus FlashFrozen.
If you watch video on websites that also have animated ads beside the video (instead of in the video), you’re getting the double penalty of Flash video plus Flash ads at the same time. ClickToPlugin might be a good option here. You can just click on the main video to enable it, and leave the ads disabled, giving you the best chance of the MacBook Air staying cool and quiet.

Flash seems to be the most common cause of the MacBook Air overheating and fan running fast.
Cause #4: Software Incompatible with Lion
Some software doesn’t work with Lion. If it contains software that runs in the background and restarts automatically, the software can start over and over again.
I’ve seen one case of this, when someone migrated five years of accumulated software from their old Mac to their new MacBook Air using Apple Migration Assistant. The person was very technical and fixed the broken software themselves. This may have been old HP printing software, but I haven’t confirmed this.
For the technically inclined, there wasn’t much CPU usage, but with the process continually respawning the was a high run queue for the CPU.
I’ve seen serveral cases where people an overheating MacBook Air and noisy fans ran the free Onyx utility and that fixed performance issues. Write a comment if you’d like more specifics. In none of these cases has anyone reported the root cause of the problem, but for now I’ll include these cases here.
Cause #5: System Management Confused / Needs Reset
Thanks so much to Chris posting a comment about this:
I was experiencing a similar problem on my new MBA 13″ with i7 (loud fan with nothing running), along with some other odd issues related to battery and power. System preferences (energy saver) claimed my battery was charged at 0% (though I knew that was not the case), and I couldn’t add the battery status to the menu bar (I would click that option, the menubar with reconfigure as if to accommodate the new icon, but then it would disappear). Furthermore, when plugged in to AC, I got no lights (green or orange) on the MagSafe adapter. The support page at http://support.apple.com/kb/ht3964 suggested that weird battery/power issues may be solved by an SMC reset, which I did. The fans have now stopped and the other symptoms that I mentioned have also gone away. https://gnxuvhi.weebly.com/blog/mac-music-app-catalina. Perhaps this can help with others.
So Chris’s MacBook Air symptoms were:
You may not have all these symptoms.
