David A. Cox: If you have made the decision to sell your Mac,
then this is the video for you!
Today, I'm going to walk you through everything you need to do
BEFORE you list your Mac for sale.
That's coming up next on Tech Talk America!
Hey folks, and welcome to the class.
Part of the reason why I wanted to make this tutorial is because one of the
most important pieces of information on this subject is what NOT to do.
Now, this may sound obvious to some of you, but trust me, it is
worth mentioning. Whatever you do, do NOT manually delete your files.
Every so often I get a tech support request from someone who has done this.
They buy a new computer, migrate their data.
So they think, "Okay!
The data's there!
It's safe!
Right?
So I'll just drag everything into the trash.
And then they go to log into their new computer and have a heart attack when they
realize that all of their files are gone.
The reason why is because iCloud syncs those changes
right back to the new computer.
So whatever you do do not manually delete your files.
If you're unsure, what's the best way to migrate your data to your new computer.
I suggest that you check out my video on the subject matter.
I'll put a link to that down below in the video description.
At this point, let's talk about what you do need to do before you wipe your data.
For starters, you're going to need to de authorize the music app to do
this, click into the account menu, then hover over authorizations and
select deauthorize this computer.
Now we'll need to do the same thing for the TV app.
So let's launch that once again, go into the accounts menu, hover
over authorizations and select deauthorize this computer.
The next thing we need to do is to turn off the, Find My Mac feature.
Let's go to the Apple icon at the top left and go into system preferences.
Now let's navigate to apple ID and here in this list, just make
sure Find My Mac is disabled.
Here on the left, you will see a list containing all of your registered devices.
You can't remove a device from that device.
So you'll need to go on something like your iPhone, iPad, or another Mac and
remove the device you're about to sell.
If your Mac is still covered under Apple Care, you can transfer
coverage to the new owner.
However, it does require that you have the original sales receipt
and the new owner's information.
To transfer AppleCare,
you do actually need to call them that number is of course 1-800-MY-APPLE.
If your Mac is running Mac OS Monterey or newer erasing, the data is super simple.
Just go into system preferences and then click where it says system
preferences in the top menu bar, then click erase content and settings.
When this process finishes, you do not need to reinstall the operating system.
The reason why is because there's an installer on a separate partition.
So once it's done erasing your files, you're good to go.
If you're running an operating system that's prior to Monterey,
here's what you'll need to do.
Start by shutting down your Mac.
Once it is completely turned off, you'll need to press and release the power
button and then immediately hold down command and the R key on your keyboard.
You can release them once you see the Apple logo with a progress bar.
You may be asked to enter in your admin password, and then you should
see a screen that looks like this.
Now let's select disc utility and click continue on this next screen.
You'll need to select the data portion of Macintosh HD.
Then click erase, here in the top menu bar.
This is the last screen you'll see before it erases your data.
You'll want to keep it named Macintosh HD and here under format, make sure it's
set to APFS or Mac OS extended journaled.
If you see both, go with APFS.
Now, click erase.
If this video helped you, please consider clicking that super thanks button, that
allows you to leave a little tip of your choosing, even if it's as little as $2.
Thanks so much for watching everyone.
