Prepare Mac computer for sale: turn off Find My Mac and EFI protection password, sign out of certain services and delete (erase) your old data before doing so.
One day, we all come to the point when we feel that it’s time to upgrade our devices and to say goodbye to the ones we own now. This is when we start considering what to do with our current device, like to sell it, give it away to a family member or use a trade-in program. Whatever way you choose, you need to make sure your data and personal info is safe and a new owner won’t have access to it while using your old Mac.
Here you’ll find all the information you need on how to prepare your Mac for sale and secure all your data and personal information. This guide will provide you with a step-by-step manual how to accomplish this.
In case you don’t want to lose all your data you keep on your current Mac and use it on your new computer, our advice is to back up your device before you move to the steps described below. Time Machine is the simplest backup method as this feature is already built-in into your Mac. All you need to successfully backup your Mac is an external hard drive. Actually, making backups of your computer from time to time is a wise thing to do even if you don’t plan to give it away, sell or whatever. This way you make sure all the data you keep on your Mac won’t be lost in case your computer crashes and so on.
Signing your Mac out of your Apple ID or iCloud will stop access to all your data stored in iCloud. At the same time, all your data and backups you store in iCloud will remain available to you from your other devices you use with your Apple ID. Once you sign your Mac out of your Apple ID, the following features become unavailable on it:
Please note that your Apple Cash and Apple Card accounts remain linked to your Apple ID and can’t be transferred to or accessed using any other Apple ID.
You will also automatically sign out of the App Store, iMessage, and FaceTime once you sign out of iCloud.
In the process, you may be asked whether you want to keep a copy of your iCloud data or Safari passwords on this Mac. You can do this if you like, however this information will be erased anyways as you’ll be recommended to erase your drive going forward. If you still want to keep this information, here is what you should do.
The next step you should take is to sign out of iTunes and other related services, as well as to deauthorize your Mac. Below you’ll find a step-by-step guide on how to do so:
As you may have already heard, this is the last year iTunes is available. According to Apple, iTunes will be discontinued from the end of 2021. So, going forward, you’ll be able to sign out of your accounts using the Music, TV or Books apps. You can open any of these apps and do the following:
We also recommend you to make sure you signed out of Messages app by:
In the event that your Mac is equipped with T2 security chip and is protected with EFI Passcode, which is Extensible Firmware Interface, you should turn it off to enable a new owner of your Mac to perform following operations on it:
If you have turned this feature on, here is how to turn it off:
You already know that EFI passcode is an extra security measure designed for macOS related processes, like macOS installation, reinstallation, hard disc erasing, and Mac restoring using Time Machine. You need to enter the EFI Firmware passcode to turn it off prior sale as a new owner won’t be able to perform the aforementioned processes. The firmware passcode screen appears right after your Mac is booted.
However, the chances are that you might forget the EFI passcode for any reason. So, what can you do in such circumstances. First of all, stay calm as we’ll describe several ways for you to handle this problem.
The first approach you can try here to reset, change or disable the EFI firmware passcode is to use the same method you used to set the password. You’ll be required to boot your Mac into Recovery Mode for this method:
You’ll see a message saying that password protection is off in case of success. This is not a 100% reliable method. It works in some cases, but the chances are it won’t work in your case. However, it’s worth a try.
If the method described above won’t help you, you’ll have to turn to Apple or Apple Authorized Support center as they can bypass or reset the EFI password for you using proprietary tools.
Quite possible that you’ll have to prove your ownership to them to unlock your locked device. However, some exceptions are possible for a number of unusual circumstances. You can discuss this issue with them directly.
There are cases when methods described above are not an option to bypass EFI Password on Mac. For this reason, the CheckM8 dev team created EFI Unlock Software to help users facing this problem. CheckM8 Software is a reliable tool allowing to bypass Mac EFI security firmware (BIOS) password protection and disable secure boot for all Apple Mac computers with a T2 security chip like: MacBook Pro and Air, iMac, iMac Pro, Mac Pro & Mini running on macOS 10.12 Sierra and up to macOS 11 Big Sur.

As a bottom line, our hope is that this post was helpful and gave you all the information you need to prepare your Mac for sale. Following these advices, you make sure your personal information and data stays safe and the new owner of your Mac won’t have access to any of it.
Now you are ready to erase all your data and information from your Mac computer which you are about to sell. Doing so you’ll erase your Mac’s drive and restore it to its factory settings.
There are many ways to have this done. But we’ve chosen the easiest way for your convenience. Our advice is to use Disk Utility to format your drive and reinstall macOS.
The final step you should take before giving your Mac to someone else’s hands is macOS reinstallation. There are several ways to do this and we’ll list them for you here.
You should use macOS Recovery for the purpose of macOS reinstallation. So, start up your Mac from macOS recovery. You should determine the type of your Mac, is it Apple Silicon or Intel processor. Once determined, choose one of the following options:
You may be asked to select a user you know the password for, do it, click Next, and enter administrator password.
Now let’s start macOS reinstallation itself!
Select Reinstall macOS option in the utilities window in macOS Recovery, click Continue and follow the on-screen instructions and following guidelines:
Once macOS installation is complete, the chances are that your Mac will restart to a setup assistant. Since your plan is to give your Mac to other people’s hands via sale, trade-in or in any other way, the best choice is to quit the assistant without completing setup by pressing Command-Q and clicking Shut Down. This way, a new owner will use their own information to complete setup when he or she starts up the Mac for the first time.
As for other macOS reinstallation options, you can find them below. Please note that by default macOS Recovery installs the latest macOS version which was previously installed on the Mac. One of the following options will allow you to install other macOS versions.
For intel-based Macs which were previously running on macOS Sierra 10.12.4 or later, you can use Shift-Option-Command-R at startup. This option will install the macOS version your Mac came with, or the closest version still available.
You can also use the App Store instead of macOS Recovery to reinstall macOS on your Mac. In case you can’t install the latest macOS version released, the chances are you’ll be able to install an earlier version.
One more option available to you is to create a bootable installer and use it for macOS installation on your current Mac or another Mac.
As was already said, you should turn Find My Mac off while preparing your Mac for sale. You’ll have to enter your Apple ID and password to do so. But if your Apple ID is locked for some reason, you should unlock it before turning Find My Mac off. Below you’ll find a detailed guide telling what to do in case your Apple ID is locked or disabled.
For those using two-factor authentication, you’ll need to have a trusted device or phone number at hand to reset your Apple ID and password which, in turn, will unlock your account. You can also use a recovery key if you have one.
In the event that your device displays a message saying your account has been disabled in the App Store and iTunes Store, you should contact Apple Support for help.
In case when your Apple ID was locked for security reasons, one of the following alerts may be displayed:
There is another option you can use if you use a security question with your Apple ID, or if a trusted phone number or device is unavailable. You can go to iforgot.apple.com to unlock your account with your existing password or reset the password. Your Apple ID will remain locked after multiple attempts to unlock it. However, you can try again the next day.
The truth is, a large number of users find themselves in the situation when they just forgot their Apple ID or password used for their Macs, or they can’t use options listed above for some reasons. So, if you enter incorrect Apple ID or password several times, your Mac becomes Activation Locked.
This is why the CheckM8 dev team designed the software capable of bypassing Find My Mac Activation Lock on Mac computers equipped with Apple’s T2 security chips running on macOS 10.12 Sierra and up to macOS 11 Big Sur.
The CheckM8 Software works on the following computers:
