But you are only allowed to authorize up to 5 computers. And if needed, you can authorize your computer later. If you sell or give away a computer that still has one of your five authorizations, you then need to deauthorize all of your computers and then re-authorize each one that you still use. Unfortunately, it does not list the names of those computers.

Alternatively, select Deauthorize all computers to clean your five authorizations. Then reauthorize all your computers one at a time up to 5. As a side note, you are not able to authorize a computer from another computer or your iPhone, iPad, or iPod touch. Many third-party applications include machine authorizations and activations, particularly image, sound, and video editing programs. For example, most Adobe programs require activation. Application Activation is the process of connecting a particular application to a valid user license. On the other hand, deactivation disconnects an application from a valid user license.

Once deactivated, you can reactivate that license at any time, on any computer. You do not need to uninstall an application from your PC to deactivate it. Despite conventional wisdom, uninstalling an application does not necessarily deactivate its license. So check your list of applications, looking for any programs that require activation keys. Go to the Apple menu at the top left of your screen and select System Preferences.
Then choose iCloud and click Sign Out.
Select your iMessage account and click Sign Out. Its utilities allow you to erase the internal hard drive fully.
Follow the onscreen instructions. Open the App Store and use the Search field to find it. Once located, download and install it from that product page.
I mean, this is life, and things happen. We install a lot of applications, updates, and maybe even do some poking about the system operating software using Terminal or third-party apps. This is real and expected use. And start your next day with a clean OS slate.
And the new owner starts off with a fresh start—no clutter remaining from all your previous applications, preferences, etc. So be nice to yourself and the new owner by removing and securing your data through a factory reset on your Mac! And never, ever forget to backup your data first through Time Machine or your backup method of choice, before performing ANY of the steps to reset your operating system.

Learn how your comment data is processed. Hi, a quick question about this process. If you reset your Mac back to factory status, the only apps it downloads are what came installed on it when shipped from the factory—so it would not include Final Cut or Logic Pro. Otherwise thanks for nice article on factory reset and sharing some experiences of how others handle situations. Just a thank you for the clear and concise instructions! My MacBook Air was so slow after crashing and thought it would be unable to support my needs. This worked like a charm! That might have been my timing, though.
The second time, by the time the startup beep sounded, I had the buttons compressed. Unfortunately, these instructions do not work if you buy a MacBook Pro at a yard sale and it is missing the hard drive. Close your MacBook and turn it over. The serial number and model information should be visible on the back side of the computer, near all the regulatory information. Then, purchase the disks for that version for older Mac OS X versions, try amazon, the Apple Store ionline shop, ebay or similar.
Have you tried starting up in Internet Recovery Mode? You need a reliable and fast internet connection to do this. Beeping is often indicative of corrupted RAM. You may be able to isolate the problem by paying attention to how many beeps you hear when starting up. If the issue continues, contact Apple Support. This applies to Mac computers from before Newer computers automatically recover from a corrupted ROM; when this occurs, a progress bar appears on the screen during ROM recovery mode.
When recovery is complete, your Mac restarts. If so: unlock the disk, format, then install macOS.
In disk utility it is not letting me bring up any kind of menu by click on the drives. Most of the options other than first aid at the top are grayed out. GLRico said:. Sorry for the inconvenience, just need to be sure what you're seeing and hopefully we'll figure it out. I'd like to but when I try uploading a pic from my iPhone it says it is too large. I don't have any URL links or know how to go about that. Is there any information I can look for specifically?

Ok wait think I got it. Ah no problem. I should've suggested a few other things anyway. This will boot into Internet Recovery. Erase and restore are no longer grayed out! Only when I start it up and don't press anything does it bring me to the screen where I can see options like disk utility or reinstall OS X.
