I have transferred everything to my new lap top, now how do I remove the info from the old lap top and not the new

The solid Apple is not in the Mac's ROM at cold-start. Seeing the solid Apple says your boot drive was able to load the fist "blob" of software, initiate it and continue. So your Mac Hardware is working and your boot drive is mostly functional.

The next hurdle requires many files by name, so your Mac attempts to Mount the drive File System. If damaged, it will proceed to a disk check. If the damage can not be repaired, your Mac has nowhere to go, so it shuts down.

Your Mac is working.

Your drive has directory damage that can not be simply repaired, but an Erase may make it good enough for a new Install from Recovery.

20 seconds is not long enough.

Press all keys immediately after startup, and wait for the chime (if your Mac usually chimes at startup). Keep holding them for another minute or two, and if successful, you will hear another chime, and then another chime.

Thank you for the instructions on how to disable the MacBook Air. I can't get the Mac Book Air to even boot up. I hit the on button. The apple logo shows up and it starts to load. Then the computer just shuts down. We haven't used this old one for about a year and I want to take it to Apple to recycle.

If your old Mac is older than 2011 model, post back with its model-year for additional guidance.

If your old Mac was released after 2011, hold down Command-R at startup and this should get you to Recovery mode. This provides the Utilities, including Disk Utility, that used to be on the Installer DVD. With a good internet connection, you can try to erase the drive and install the factory-released MacOS.

I bought the MacBookAir in July of 2011. When I hit control R and the on button it brings up a world globe and asks to choose a net work. When I try to choose my network from the drop down list and hit enter nothing happens. Please advise. Or should I just take the computer to the Apple store and have them erase everything.

It can take many minutes to complete loading using Internet Recovery. if it does not immediately generate an error message, try to be patient and see if it makes progress.

The advantage of Internet Recovery is that it uses more than 20 RAM disks to hold its temporary items, so your disk is available to be completely erased, removing everything.

OK. I am now at MAC OS X Utilities.

Options are:

Restore From time machine backup

Reinstall Mac OS X

Disk Utility

Which option so I want so I can now clean out the computer and take the computer into the Apple store to recycle it.

On the OLD computer, you want to do two steps:

1) use Disk Utility ERASE everything. all your personally identifiable information, MacOS tagged with your Apple-ID, and your Paid Applications will be removed. However, that leaves the computer in very limited state.

2) unless you HATE the next recipient of the computer, it is considered polite to download and Install the originally-issued MacOS, which can also be done from Recovery. The originally-issued MacOS is tagged only with the serial number of the computer, and NOT your Apple-ID.

Once installed, you can try it out, but do NOT enter a new userid. At that point, quit Setup Assistant and Shut Down the machine, so that the next Owner can set it up for themselves. Do Not Install the latest version of MacOS, because all those versions are tagged with your Apple-ID.

So what can I do. Nothing is loading. It just shuts off when I try to boot up.

Reinstall Mac OS X

That indicates an old version of Internet Recovery that may not work properly. Do you have access to another Mac?

Thanks for your help. I will now take the old computer in to recycle.
