How to Maintain a Mac (6 Steps)

Run maintenance scripts to maintain your Mac. These are built into your OS and will run automatically if you leave your system on all the time. If you shut your system down every day, remember to run the appropriate Mac maintenance scripts on a daily, weekly and monthly basis.
Check your hard drive periodically. This can be done from your Disk Utility on your hard drive, or you can boot up from your install CD and run the Disk Utility from there. You will need it anyway should the utility need to repair your hard drive.
Back up your files. You can back up as often as you feel you need to--some people back up daily. In the event of a hard drive crash, you will have a separate copy of all your files. Most users do this with an external hard drive.
Repair permissions to maintain your computer. You really only need to do this after you install any new software or before you clone your hard drive. The Mac was designed to be low maintenance.
Reinstall when necessary. If you are running OS X 10.2 or higher, use the feature called 'Archive and Install.' It will move your system files into a 'Previous System' folder and reinstall your OS. Do this only when you have tried other measures and only after you back up any files you want to keep.
Create a backup of your hard drive on an external Firewire drive.

How to Use Hotspot Shield on the iPhone, iPod Touch

Open the App Store.
Tap 'Search' on the navigation bar, type 'Hotspot Shield' in the search tool and tap 'Search.'
Tap 'Hotspot Shield VPN' to go to the information screen. Then tap 'Free' and then 'Install' to download and install the program. Enter your Apple ID and password at the prompt and tap 'OK.'
Open the Hotspot VPN app from the Home screen.
Select whether to try the app free on a trial basis for seven days or to purchase a monthly or yearly subscription. If selecting the pay options, tap the 'Buy' button to confirm the purchase and enter your Apple ID password. Otherwise, tap 'Try it for free.'
Select either 'Always On' in the VPN settings to launch the Hotspot Shield automatically when the iOS device is turned on or 'Manual' to turn on the service manually. 'Always On' is a good option for novice users while 'Manual' is more useful for advanced users.
Tap 'Install' in the 'Install Profile' screen to install the settings for the iPhone or iPod. Tap 'Install Now' at the next dialog box to add the Hotspot Shield VPN configuration. Tap 'Done' when the installation is complete. Exit Hotspot Shield.
Tap 'Settings' on the Home screen and go to 'General.' Tap 'Network' and then 'VPN.' Toggle the switch to 'ON.' If you selected 'Always On,' the VPN remains connected without user intervention. If you selected 'Manual,' you must enable the VPN service in Settings each time.
Go to 'Settings,' 'General,' 'Network' and 'VPN' to disable VPN, if needed. Slide the switch to 'OFF' and exit 'Settings.'
Browse the Internet as usual.
