Why won't my macbook air turn on completly just at the start up page and under the apple logo there's a bar that just loads and when its done loading the Mac just powers off this just happens over and over I'm afraid if I do any thing my pictures will be lost on the computer ???
Thanks for the question. If you have updated to Yosemite, then the Apple Logo with the status bar is the expected behavior for when the computer starts up. However, the powering off is not supposed to be happening ... so here are some steps to take if your MacBook Air won't turn on.
Immediately after you hear the startup sound, press and hold the Shift key. The Shift key should be pressed as soon as possible after startup, but not before the startup sound.
Release the Shift key when you see the Apple logo appear on the screen.
After the Apple logo appears, it may take longer than usual to reach the login screen. This is because your computer is performing a directory check as part of Safe Mode.
To leave Safe Mode, restart your computer without pressing any keys during startup.
If your computer won't turn on, try each of these steps:
Verify you have a good connection from your Mac to the wall outlet by confirming the power cord and adapter if present are securely connected and plugged in. To check if the wall outlet is working, plug in a lamp or other electrical device.
If the wall outlet is working and you continue to have no power try another power cord or adapter if available. If it works you may need a replacement cord or adapter.
