How to Keep a Mac From Overheating (4 Steps)

Download Apple's firmware fix to adjust your Mac's fan. Navigate to Apple's Firmware Update 1.3 Web page. Click on 'Download' on the right side of the page. Open your 'Downloads' file, and click on 'SMC Update.pkg.' Click 'Continue,' then 'Agree.' Click 'Install.' Restart your MacBook Pro.
Place your laptop on solid surfaces. If you use your laptop while it's sitting on soft surface, such as a pillow or blanket, the vents on the back of the MacBook may be blocked. This will cause the Mac to overheat.
Store your laptop in a cool, climate-controlled environment. Never leave your Mac in a hot car or in direct sunlight. When the electronic components get too hot, they won't perform correctly when you turn on your computer. This can cause the fan to malfunction.
Purchase a laptop cooler. If you spend hours at a time on your computer, a laptop cooler can help keep your Mac from overheating. Most laptop coolers are metal platforms that elevate your laptop off your work surface. They have incorporated fans that provide extra airflow to keep your laptop cool. Some require an electrical outlet to power the fans, while others plug into a USB port on your laptop.

How to Fix a Mac OS Crash

Press 'Command-Option-Esc' at the same time. The Force Quit Applications window opens, displaying all of the open applications, with 'Not Responding' beside the application that caused the Mac to freeze. If this window does not open, press 'Command-Option-Shift-Esc' for three seconds to force quit the unresponsive program. Then open the Force Quit Applications window.
Click any application that says 'Not Responding' and click 'Force Quit.'
Restart your computer if you have not shut it down in more than 24 hours. This will clear memory being held by any troublesome applications.
Click the 'Finder' in the Dock to open a new Finder window. Click 'Applications,' then the 'Utilities' folder. Double-click 'Activity Monitor.' This will show you what resources are being used by processes and applications.
Click the '%CPU' tab to sort this column. Processes and applications are now sorted in descending order. Processes using most of the Mac's CPU (Central Processing Unit) will be shown first.
Click the 'Real Memory' tab to see which processes and applications are using the most memory. Do the same for 'Virtual Memory.' Real memory is stored on the memory chips, while virtual memory is stored on the hard drive.
Close any application that is using an unusual amount of memory or percentage of the CPU. What is unusual for memory usage will depend on the programs you run, but anything over 700MB should be examined. Any process using more than 20 percent of the CPU for more than a second or two should be considered unusual.
Relaunch the application that caused the Mac to crash.

How to Make a Stylus

Select an ink pen and a stylus. The first thing you'll need to determine is if your stylus will fit inside the ink tube of the pen. Your best bet is a narrow stylus and a pen with a wide ink tube.
Take apart the pen. Remove all the internal components of the pen including the ink tube and any springs inside the pen.
Remove any appendages from the stylus. Many styluses have small adaptations which serve as a grip or a tab to help hold the stylus in the device. Cut these adaptations off to help the stylus fit inside the pen.
Drain the ink from the ink tube. You will want to make sure you have drained all of the ink to prevent dripping ink on your device's screen. To drain the ink, remove the pen point from the ink tube. After pouring out the ink, soak the tube in hot water to get rid of any remaining ink.
Insert the stylus into the ink tube. If it does not fit, try using an ink tube from a different pen.
Put the contents of the pen back together. Make several stylus pens to keep at work and around house so you'll always have one within reach.
