Do These 7 Things to Prepare Your Mac for a Repair

Updated: Dec 9, 2022


It's inevitable. At some point, your Mac will need to go in for repair. Maybe the screen cracked, the logic board failed, or water damage ruined the keyboard. Whatever the case may be, you'll need to take your Mac to an Apple Store or an authorised service provider to get it fixed.

Before you do that, though, there are a few things you should do first. This comprehensive guide will walk you through everything you need to do to prepare your Mac for repair.

1. Back Up Your Data

The first thing you should do is back up your data. This is important because there's always a chance that something could go wrong during the repair process, and you could lose your data. There are a few different ways you can back up your data:

- Use Time Machine: Time Machine is a built-in feature on macOS that allows you to back up your data to an external hard drive. To use Time Machine, you'll need to connect an external hard drive to your Mac. Once it's connected, open Time Machine from the Applications folder or the System Preferences. Then, follow the on-screen instructions to set up your backup.

- Use iCloud: iCloud is a cloud storage service from Apple that allows you to store your data online. To use iCloud, you'll need to sign up for an iCloud account and enable iCloud Drive on your Mac. Once iCloud Drive is enabled, you can access your data from any device by signing in to your iCloud account.

- Use a Third-Party Service: There are a number of third-party cloud storage services, such as Dropbox, Google Drive, and Microsoft OneDrive, that you can use to store your data online. Each service has its own pricing and features, so be sure to compare them before you choose one.

2. Gather Your Important Documents

Once you've backed up your data, you'll need to gather any important documents you have on your Mac. This includes things like your product registration information, warranty information, and receipts. These documents will be helpful if you need to contact Apple or an authorised service provider about your repair.

3. Enable Guest Access

One of the first things you should do before taking your Mac in for repair is to enable guest access. This will allow the technician to access your Mac without having to know your password. To do this, go to System Preferences > Users & Groups. Then, click the lock icon in the bottom left corner to unlock the settings. Next, click on the Guest User account and select "Allow guests to log in to this computer."

4. Turn Off Find My Mac

If you have Find My Mac enabled, you'll need to turn it off before taking your Mac in for repair. Find My Mac is a feature that allows you to track your Mac if it's lost or stolen. However, it can also prevent someone from being able to access your Mac if it's in for repair. To turn off Find My Mac, go to System Preferences > iCloud. Then, uncheck the box next to "Find My Mac."

5. Turn Off Your Firmware Password

If you have a firmware password set on your Mac, you'll need to turn it off before taking it in for repair. A firmware password protects your Mac from being started up from any external drive or CD. To turn off your firmware password, restart your Mac and hold down the Option key while it's booting up. Then, select the Recovery HD and open the Terminal. In the Terminal, type "csrutil disable" and press Enter. This will disable the firmware password.

6. Deauthorise Your Computer for Content Purchases

If you have any content purchased from iTunes, the App Store, or iBooks, you'll need to deauthorise your computer before taking it in for repair. This will prevent the technician from being able to access your content. To deauthorise your computer, go to iTunes > Account > Authorisations> Deauthorise This Computer.

7. Erase Your Hard Disk

Before you bring your Mac in for repair, you should erase your hard disk. This will ensure that all of your personal data and files are wiped from the device before it goes into the hands of a technician. To do this, you can use the Disk Utility application that comes pre-installed on all Macs. Simply launch the app, select your hard drive, and click on the "Erase" button.


If you're planning on taking your Mac to a repair shop, it's a good idea to follow the steps outlined in this guide. This will help ensure that your data is backed up and that you don't lose any important files. Additionally, it's always a good idea to have a backup plan in place in case something goes wrong during the repair process.
