How to Organize Files on a Mac

Create a new folder (Apple-Shift-N) on your desktop and name it 'Desktop Files To Be Sorted.' Drag all of the files and folders on your desktop into this folder. Create a second folder on your desktop, and name it 'Hard Drive Files To Be Sorted.' Drag all your personal files and folders that reside on your hard drive (which doesn't include the Applications, Library, System and Users folders) into this folder. Apart from the hard drive icon, the only items on your desktop should be these two folders.
Create a third folder on your desktop, and give it a name that indicates that it is your main folder, perhaps something like 'Master Folder.' Double click on Master Folder and create the following folders inside of it:
Admin '
Home '
Work '
This means that every one of your files and folders will reside in one of three of these subfolders. Each of these will have two or more subfolders inside of it that will allow you to find anything quickly. Note that this is the simplest file structure for the home user. Mac users at work or those who freelance might require a more complex file hierarchy.
Customize each of the folders by adding subfolders tailored to your specific needs. For example, 'Admin' subfolders could include insurance information, family records and children's schoolwork and activities; 'Home' subfolders could include financial information, anything to do with hobbies at home (eBay or recipe files, for example) and anything house or home-related; 'Work' subfolders could include freelance work, backup files from your job and resume and job search information.
Open the 'Desktop Files To Be Sorted' folder. Drag the window to the left-hand side of your screen, and open the 'Master Folder.' Drag that window to the right-hand side of your screen. Then start dragging the files into their appropriate folders within the 'Master Folder' (or the appropriate subfolders within the 'Master Folder'). This is also a good chance to trash any unnecessary files and folders. Repeat this process with the 'Hard Drive Files To Be Sorted' folder. When both the desktop and hard drive folders are empty, drag them into the trash.
Use a software package to make a virtual catalog of your files. While Apple's Spotlight program (built into OS X) is decent enough, most users find that a third-party application such as Tri-Catalog makes locating files and folders much faster and much more intuitive.
Back up your files. In the event of hard drive failure or theft, you'll be kicking yourself if you don't take the time to properly back up your files. Professional recovery services can cost thousands of dollars, so avoid it by backing up your files on a regular basis, which is a simple and inexpensive process. A three-tier backup is recommended: An occasional backup of the Master Folder on DVD, a Time Machine backup of the Master Folder to an external hard drive (USB or FireWire) on a regular basis and an online backup using one of the online data backup services, such as Mozy. See the References section below for more information on these backup schemes.
Review your files on an annual basis. You may want to archive files that have no current significance, but are worth keeping, and renew some items (such as an annual medical expense spreadsheet). The idea is to keep your Master Folder streamlined, and avoid the file duplication and clutter that you previously had.

How to Ping Your Network From an iPhone (8 Steps)

Make sure that your iPhone is connected to the network you want to scan via WiFi.
Go to the App Store on your iPhone and download the 'Network Ping Lite' application. It is a free app as of this writing.
Open the application and you will see four choices: Ping, Ping Subnet Traceroute, and Telnet. For this article we'll focus on the functions related to pinging.
Choose 'Ping' to ping a specific device.
Enter the DNS name (google.com) or IP address of the specific device you would like to ping and hit 'Start.' Your iPhone will now send out four ICMP packets and will tell you the outcome in the 'Output' section.
Note: You can do a continuous ping by flipping the 'Ping Forever' switch at the bottom.
Choose the 'Ping Subnet' icon to ping an entire subnet.
By default, the app should pick up the subnet that your iPhone is already on. You can change it to check a different subnet or range of IP addresses. (Note: It can only check Class C network subnets.) You can adjust the 'Ping Delay' which is the amount of time that the app will wait for a reply from the device before it declares it failed.
Hit 'Start' and the scan will begin. You'll see a table of all the possible Class C IP addresses for that subnet and the app will change the color of each as it scans to let you know which ones replied. Black = no reply. Green = Received reply. Yellow = last request failed. Red = stopped giving answer. The scan will take several minutes to complete, so be patient.

How to Replace a MacBook Battery (5 Steps)

Turn your MacBook upside down, with the Apple logo facing downward. Check the bottom panel for a removable battery. If the bottom panel is a solid block, you have a 'uni-body' MacBook, and the battery can only be replaced by an Apple authorized service technician.
Purchase a replacement battery from an Apple Store, an Apple authorized reseller or a third-party manufacturer. Be certain to purchase a battery specific to your MacBook model. Batteries made for other MacBooks may not fit in the case or may supply the wrong amount of power.
Use a coin to turn the circular lock slot of the battery clockwise 90 degrees, or one-quarter turn. The battery will pop out slightly, allowing you to lift it by its case out of the battery well.
Insert the new battery in the same orientation that the original battery was placed, lining up its connector with the power jack in the MacBook.
Press the battery gently and turn the lock slot counterclockwise to lock the battery in position.

How to Network a Toshiba Television to a Mac

Power off your Toshiba television set.
Click the Apple logo at the upper left of your Mac, then click “Shutdown.” A message appears, asking you to verify that you want to turn off your Mac. Click “Shut Down” once more to confirm.
Locate the video input port on your Toshiba television. Typically video in ports are located on the back of a television. Consult the manufacturer’s owner’s manual for details about your specific TV model. New Toshiba TVs come with HDMI video input ports.
Insert the Mini DisplayPort-to-HDMI adapter’s Mini DisplayPort connector into the Thunderbolt port on your Mac. The Thunderbolt port is marked with an icon of a lightning bolt, and it accepts both Thunderbolt connectors and Mini DisplayPort connectors.
Connect the HDMI connector of the Mini DisplayPort-to-HDMI adapter to the HDMI input on your Toshiba television.
Power on your Toshiba TV and press the “Input” button on the remote repeatedly until you have switched to HDMI input.
Power on your Mac.
Click the Apple logo, then click “System Preferences,” and then click “Displays.” Click the “Show Displays in Menu Bar” check box, and then click “Detect Displays.” The Mac detects the connected Toshiba TV and automatically sets the correct resolution to display the contents of the Mac’s screen on the Toshiba screen.
Click the icon of a monitor on the menu bar of your Mac, and then click “Turn on Mirroring” from the pull-down menu if you want your Toshiba TV to show what’s appearing on your Mac’s display. If you don’t turn on the mirroring feature, the Toshiba TV serves as a second monitor to extend your computer’s desktop, onto which you can position files, folders and application windows, including video applications, such as DVD Player or QuickTime.
Click the Apple logo, then click “System Preferences” and then click “Sound” if you do not hear audio from your Mac on the Toshiba. Click “Output,” and then click “HDMI” to select it.
