How Do I Troubleshoot IPad Touch Screen Problems?

Restart your iPad to clear out any temporary software glitches or bugs. Press and hold both the Sleep/Wake button and the Home button for ten seconds to force a device shutdown. Press the Sleep/Wake button again to turn the iPad back on; check the touchscreen after the device finishes rebooting.
Clean the iPad screen to remove dust or debris that could be causing touchscreen problems. Power down the tablet and gently wipe the screen with a damp microfiber cloth, then turn the device back on and recheck the screen. Even a small water droplet can interfere with the touchscreen’s ability to accurately read touch gestures.
Open the Maps application. Double-tap the center of the map as well as each corner to troubleshoot whether your iPad’s touchscreen problems are universal or specific to one area of the screen. This is especially useful if you notice that one application has touch problems in a certain area; testing in Maps will let you know if it is the touchscreen or the app that is experiencing problems.

How to Clean Up a Mac OS X Hard Drive

Back up your hard drive. This helps protect your personal files if you accidentally delete a file while cleaning up the Mac OS X hard drive. Use a portable hard drive or flash disk, blank CDs or DVDs or an online backup service.
Empty your Mac OS X trash bin. When you delete an item on a Mac, it is placed in the 'Trash' in your Mac OS X dock. However, it still takes up hard drive space until you clean out the Mac hard drive by emptying the trash. Click 'Finder' in the top menu bar and select 'Empty Trash' from the drop-down menu.
Archive files that you do not regularly use. This consolidates multiple files and folders into a single file and also compresses the data size so that it takes up less room on your Mac OS X hard drive. Drag any documents, pictures or folders into a single folder. Right-click on the folder and select 'Archive' from the pop-up menu. Mac OS X will compress each individual file into a single file. Optionally, drag this archived file onto a backup volume (such as a blank CD) and delete the original off of your Mac OS X hard drive.
Run a 'cron' cleanup software program to delete unused system files and logs that may be taking up space on your Mac OS X hard drive. Examples include Monolingual and Cocktail. Both programs run automated scripts that quickly scan and erase unused system folders.
Uninstall unused applications. Over the course of time, you may have cluttered your Mac OS X hard drive with various software installations. Click 'Applications' in your dock and drag any unused programs to the trash bin. Empty the trash.
