My macbook wont boot completely....stuck on the apple with spinning dial screen...tried taking out battery...holding power button...starting with just the adapter....what else can I try...? Irecently upgraded safari.....could this be a problem?

when computer is plugged in and powered off, hold down apple and option keys on left side of space bar and p and r keys. Keep them all pressed and hold them and push the power button, keep them down and listen for the boot chime to happen three times.

THis is resetting the pram or nvram.


Also try disk selct by holding down the option key or maybe try safe mode by holding down the s key.

When you say "load up screen", I assume you mean the Apple boot screen (it has the apple on a gray background).

You might try resetting the PRAM on the macbook.
You can do this by pressing and holding the Command-Option-P-R keys. You must press this key combination before the gray screen appears.

So, turn the macbook completely off. Turn it on and immediately press and hold the Command-Option-P-R keys until the computer reboots and chimes. Once it chimes, release the keys. Your system should boot normally.

Does the Apple logo or the Pinwheel show on the screen?

There is a problem with you OSX installation. Please boot from the Recovery partition (hold Cmd+R during the startup chime), and use Startup Disk to choose the correct hard drive to boot from.
You can also restore from a backup, and not lose your data here as well.

Find you apple install CD's and choose the one that says application install. as you turn in on try and put the CD in and hold down the D key this should run the disk before start up and allow you to run a hardware check.

Power the machine down. Press the power button to turn it on. After you hear the startup chime, press and hold the shift key. This will trigger an extended file system check and a safe boot. Continue holding the shift key down until you see the spinner, then you can release it. If it doesn't boot completely after this, you will have to bring it in to an Apple-certified tech for repair.

If you have your Mac OS X Install disc, insert it into the drive.
Restart the computer and hold down "C" while booting.
Choose your language.
Select "Disk Utility" from the "Utilities" in the menu bar.
Select your Macbook's hard drive in the left sidebar.
Click the "First Aid" tab thats along the top of the viewer window.
Click "Verify Disk" (not verify disk permissions)
If this shows errors click "Repair Disk"
Once completed close the Disk Utility window.
Restart the computer.
If this fails to fix it as well then your next option would most likely be recovering your files from the macbook either by booting into target disk mode (hold down T at startup) and transferring them via a firewire cable, or removing the hard drive and hooking it up to another Mac to get the files. Then do a clean install of Mac OS X using your installation discs.

Try pulling the battery out then holding the power button for 10 seconds. Put the battery back in.

If not search macbook pro recall apple has extended the warranty on some models due to a bad graphics card.

When troubleshooting a Macbook Air, there is a checklist from Apple Support you need to try.
You are welcome to do so after first trying these steps first.

• Check the Magsafe power adapter, to make sure it is free of debris and is seated properly.

• If with decent charge, try to start the Macbook Air, with only the battery.

If you get power from either one of these issue resolved- otherwise follow the steps provide more in detail from Apple listed in the link below.

Such power issues with Macbook Airs as well as Macbook 13" and Macbook Pro 13" are about the same and there are no workarounds, so make sure to follow those procedures completely for a full assessment of your Macbook Air's functionality.

Hope this helps!

You just might need to reinstall the OS.

You can turn off the machine by pressing and holding the Power button until the display switches off.
Then, try resetting your 'PRAM' using the following instructions;

I've used every version of OS X from 10.0 through to 10.5.6 and sometimes you get this problem after an incremental upgrade. It usually just goes away after a couple of reboots.
Please let me know how you go.
Thanks,
