How to Operate a MacBook

Turn on your MacBook. Press the power button with the computer plugged in. This is not a step you have to take very often. The MacBook has a low power 'sleep' mode that is much more convenient than switching the computer off. Just close the lid of the computer when you're finished using it, and open the lid when you want to use it again.
Explore the main screen---called the Desktop or Finder---of the MacBook. Notice the menu bar at the top of the screen; this bar will contain the menus for whatever program you are currently using. It also has controls and information for common tasks, such as a battery meter, a volume control and a wireless Internet control.
Explore the 'Dock' area along the bottom of your screen. The Dock contains frequently used and currently active programs. To use a program, simply click on its icon in the Dock. Try opening iCal, the Mac calendar program. Notice that the menus on the top of the screen change and the name iCal appears on the left side of the menu. To quit a program, click and hold on its icon in the Dock until the 'Quit' option appears.
Customize your computer. Click on the apple at the far left of the menu bar and select 'System Preferences.' This is where you change any system setting you like. Explore the various options inside System Preferences. Don't worry---you will have to enter your password before it allows you to make any serious changes.
Explore your home folder. Click on the blue smiley face on the left side of the Dock, and your home folder will appear in a new Finder window. From here, you can access your photos, movies, music and documents.
Explore the Applications folder. Your MacBook has many more applications than are shown on the Dock. To access them, open a new finder window (the blue smiley face), and click on the 'Applications' icon on the left side of the window. Double-click a program to start it, or if you prefer, drag the icon to the Dock to make it a permanent fixture there.

How to Eject Flash Drive on Macintosh (4 Steps)

When you insert your flash drive into the USB port, does it have a little light that blinks on and off? If it does, that's good, because that light tells you when the computer is accessing the drive. Most drives have a blinky light, but if yours doesn't, consider buying a different one.
When you want to remove your flash drive, you first have to 'dismount' the disk from the system. On a PC there's a little menu item in the lower right corner where you can choose 'safely remove hardware' or something like that. On a Mac, you have several choices to remove the drive. The easiest and most common way is to drag the disk's icon to the trash.(Note that when you do this, the trash icon turns into an 'eject' icon - which is a line and a triangle pointing upward. In the old days people used to be afraid to drag their disks to the trash can for fear they would delete their files. So they changed the icon.)
Wait until the icon disappears from the desktop, but DON'T PULL IT OUT OF THE USB PORT YET. Look at the flash drive. Is the light blinking? If so, leave it in. When it stops blinking, you can pull it out.
Sometimes the computer refuses to let the flash drive eject. It will tell you that files on it are still in use. It can't eject as long as the computer is using the drive. The problem is that your applications sometimes use the drive, even after you are finished. So if you get this message, first make sure all docments are closed, and if that doesn't work, quit any applications you were using with the flashdrive. (Glance down at your dock - there will be a little black triangle under each icon with an open application.)If your computer just won't let go of your thumb drive, even with all applications closed, you can try two other measures. Use option-command-escape to bring up the 'force quit' window, and choose the Finder. You can't actually quit the Finder, but you can 'restart' it, and that will cause the screen to blink and redraw. If all other applications are closed, you should be able to eject your flash drive after that.On rare occasions, some process may still be locking up your flash drive. The last resort is to shut your computer down. When it's off, it's always safe to remove the usb flash drive or thumb drive.
