How to Use Boot Camp to Install Linux

Download and install rEFIt (see Resources). This is a tool required to allow booting into other partitions, such as the Linux partition, not traditionally supported by Boot Camp.
Click 'Applications' 'Utilities' and then 'Boot Camp Assistant.'

Insert your Linux distribution installation CD when your partition has been created. Click 'Restart Mac OS X.'
Hold down Alt (option key) on your keyboard as your Mac is booting up.
Click the CD icon that says 'Windows.'
Follow the on screen Linux installation instructions to install the operating system.
Click the 'fat32' partition when the partition manager appears. Delete the fat32 partition.
Create two partitions, one around 600MB in size, the other with the rest of the full space. Name the smaller partition 'swap' and the other formatted as 'ext3' with 'root' or '/' assigned to it. Complete the installation then eject the Linux disc.
Hold Alt on your keyboard as your system is booting up. Click 'Windows' to boot into Linux.

How to Connect iPads to Monitors (4 Steps)

Charge your iPad fully, particularly if you plan to use the Apple VGA adapter. The digital AV adapter features a space to plug in your iPad charger while using the monitor, but the VGA adapter does not. Either way, a fully charged iPad will allow you more flexibility to place your iPad where you can best use it with the external monitor.
Plug the appropriate adapter into your iPad's docking port.
Plug the appropriate connecting cable into the adapter's out jack and into your monitor or TV. Use an HDMI cable for the digital video adapter or a VGA cable for the VGA adapter.
Launch the appropriate app on your iPad. On the iPad 2, your display will appear on the external monitor as soon as you have it plugged in. On the original iPad, the display will appear on the monitor when you open an app that is compatible with external monitors.

How to Choose the Right Apple iPad

Determine if you need the newest version or last year's model. Apple frequently sells a stripped-down version of the previous generation of iPad at a discount. If you do not need a great deal of storage and do not anticipate keeping your iPad for more than a few years, this is an excellent way to save a few dollars.
Choose how much memory you need. Apple iPads frequently come with different memory capacities, with larger iPads costing more. While more memory is better than less memory, it is possible to have more than you need. Business apps and electronic books usually do not consume a great deal of space and fit well in a 16 or 32 GB iPad. If you will be storing a lot of music or video on your tablet, the 64 GB version becomes more important.
Decide which type of network connectivity you need. The lower-priced iPads come with Wi-Fi capability that achieves fast connection speeds on any available Wi-Fi network. For those users who need to connect to the Internet even when they do not have access to a Wi-Fi network, Apple also makes iPads that connect to the cellular network. These iPads cost more money and require a data service plan to use the cellular feature, which carries a monthly fee. If you need this capability, choose the iPad that provides you with the best balance of cost and quality of service. As of August 2012, cellular-equipped iPads connect to either the AT&T or Verizon networks in the United States.
Choose a color. Apple makes iPads in any color you want -- as long as it is white or black. While black iPads have a sleek, businesslike appearance, some users feel that white iPads show fewer fingerprints and smudges. This is ultimately a matter of personal preference.

Increasing Virtual Memory on a Mac

Reset your Mac's parameter random access memory (PRAM) and nonvolatile random access memory (NVRAM). Press and hold the 'Command,' 'Option' and letters 'P' and 'R' on your Mac keyboard as you start the computer. Listen for the second set of chimes and release.
Free additional disk space on your boot volume. VM on a Mac requires free disk space on your startup disk. If your startup disk is nearly full, your Mac's performance will be degraded. Delete files you no longer need. Movies take up a lot of drive space, which makes them good candidates to delete.
Consider installing a larger hard drive in your Mac. If you cannot find enough files to delete on your boot drive, it may be time for a larger drive. It is best to consult with an expert or Apple Genius for this delicate process.

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.
