MacKeeper Activation

To activate MacKeeper, you’ll need two things ready — your MacKeeper activation code and your MacKeeper account.

How to get a MacKeeper activation code

You’ll receive your activation code right after purchasing the full MacKeeper license. Here are two ways to get yours:


1. Open MacKeeper, and click the green Unlock Full Version button in the bottom-left corner

2. Choose your MacKeeper plan here


Once your purchase is processed, you’ll see your MacKeeper activation code on the screen. We’ll email it to you as well.


Activating the full MacKeeper license gives you unlimited access to all its features throughout your subscription. Remember, we never provide free MacKeeper activation codes unless it’s a very special promotion run through our official website, not through third parties.

Where to find your activation code

Immediately following purchase, you’ll see your activation code along with other order details on your screen.

Another way to find your MacKeeper activation key is to check your mailbox for the order confirmation email. Remember to check the spam or junk folders as well. Find the email with the subject: “Your MacKeeper order” and copy the 16-digit activation code from there.

How to activate your MacKeeper license

Note: usually, MacKeeper is automatically activated in 5 minutes if you purchase MacKeeper from the app. If it’s not activated, use the following instructions.


Step 1. Open MacKeeper, and go to the top-left corner of your screen

How to activate MacKeeper without installing the app

1. Open your inbox

2. Copy your 16-digit MacKeeper activation key from the order confirmation email

3. Go to, log in or create an account, and click Enter Activation Code

Why MacKeeper doesn't accept your activation code

Sometimes you might be entering your MacKeeper activation code but getting an error instead. Don’t worry, we know how to fix this. It all depends on the error you see.

1. Activation code already used: “Activation code has already been applied to your MacKeeper account. Please log in.”

This error appears when you’ve already activated your MacKeeper serial code. All you need to do is simply log in to your account.

  1. Open MacKeeper, and go to the top-left corner of your screen
  2. Click MacKeeper next to the Apple logo, choose Preferences, and open the Account tab
  3. Log in to your MacKeeper account
  4. Your valid MacKeeper license will be automatically activated

2.  Invalid activation code: “Your activation code is not valid.”

This error occurs if you either entered the activation code incorrectly, or you entered a nonexistent activation code.


Remember: A valid activation code must be 16 characters long and include both letters and numbers.


If you’ve already purchased MacKeeper, look for the MacKeeper order confirmation email in your inbox, and copy your activation code. If you still see this error, please contact our support team.
