Macintosh HD, or the MacBook internal hard drive, is basically the startup drive of most Apple computers. That means if your Mac or MacBook Pro can’t mount its startup disk, it is likely that you will experience problems, like your computer gets stuck on the login screen or it does not boot at all. Situations like this can be very annoying, especially if you have critical and important files stored on the “unmountable” hard drive.
Fret not, because we will teach you what to do if your MacBook Pro won’t mount its startup disk. But before we do that, you better have a backup of all your data.
Backup, Backup, Backup!
Before you proceed with fixing the problem, it is best that you back up all your data first. That way, you can easily retrieve or recover your important documents and files in case something goes wrong.
Now, you might be wondering if it is possible to create a backup of your data, especially that your Mac is not even booting. Here’s what you should know: your Mac has a built-in Disk Utility, which can be accessed before startup. To use this, follow the steps below:
Get an external hard drive and connect it to your Mac.
Switch off your Mac. After five seconds, switch it back on.
After hearing the startup sound, press the CMD and R keys. Hold them until the Apple logo appears.
The macOS Utilities window will now appear.
Choose Disk Utility and hit Continue to proceed.
You can now start backing up your data using the external drive. Once you have backed up all your data, you can try a few fixes to your “unmountable” hard drive problems.
4 Fixes to a MacBook Pro That Can’t Mount Its Startup Disk
In most cases, mounting is an automatic process that happens as soon as the hard drive is connected to a Mac or MacBook Pro. Then again, drive mounting can be performed manually using the Disk Utility of your machine. It will be discussed further below.
Going forward, assuming you already have a backup of your important files and data, let’s proceed with resolving the problem. Below are a few ways to fix a MacBook Pro that can’t mount its startup disk:
1. Fix Your Hard Drive.
Sometimes, restarting your Mac is more than enough to fix the problem. However, if that does not work, then you might want to look into the angle that there might be something wrong with your hard drive. If that is the case, you have to boot your MacBook Pro in Recovery Mode via Disk Utility.
Turn it back on by pressing the Power button. But while doing that, press the CMD and R keys as well until the Apple logo appears.
The macOS Utilities window will open. From there, select Disk Utility.
From the left pane, choose your MacBook Pro hard drive.
Navigate to the First Aid tab.
Click the First Aid button to start fixing your drive.
Wait for the process to finish before restarting your machine.
2. Run Your MacBook Pro in Safe Mode.
When booted in Safe Mode, your MacBook Pro will start only with the minimum requirements and utilities needed. All other programs and apps that are unnecessary will never be loaded. Hence, if the reason why your startup disk cannot be mounted is a faulty app or program, booting your MacBook Pro in Safe Mode might just fix your problem.
To run your MacBook Pro in Safe Mode, do these:
Restart your MacBook Pro.
After you hear the startup sound, press the SHIFT key immediately. Continue holding it until the Apple logo appears.
If your MacBook Pro boots up properly, then uninstall any program or app you suspect is causing the problem.
Restart your machine.
3. Disconnect All External Peripherals.
It is possible that a faulty peripheral connected to your MacBook Pro could be causing your startup disk problems. To verify this, follow the steps below:
Switch off your machine.
Disconnect all external peripherals connected to your MacBook Pro, including printers, external hard drives, USBs, and scanner. You may leave the keyboard and mouse attached in the meantime.
Switch on your Mac. If it boots properly, then one of the peripherals is causing the problem.
Identify the exact cause of the problem by connecting each of the peripherals one by one. Make sure you reboot your MacBook Pro every time you connect a peripheral.
4. Reset the SMC and PRAM.
This may sound like a technical solution, but it isn’t. In fact, resetting the SMC and the PRAM takes only a few seconds.
To reset the PRAM and SMC, follow these instructions:
Reboot your MacBook Pro.
After you hear the startup sound, press the Option, CMD, P, and R keys. Hold them until you hear the second startup tone.
Release the keys. Your PRAM will then be reset.
Restart your MacBook Pro and check if the problem persists.
If resetting the PRAM does not fix the problem, try resetting the SMC. Start by shutting down your MacBook Pro.
Plug your machine into a wall outlet.
Next, press the CTRL, SHIFT, Option, and Power keys for 10 seconds and release them together.
Restart your MacBook Pro and see if it worked.
How to Mount a Startup Disk on MacBook Pro
At this point, you probably want to know how to properly mount a startup disk on your MacBook Pro to avoid problems in the future. Well, mounting a startup disk does not literally suggest physically setting it up with all the wires. It simply means making the startup disk available for your system to perform different read and write operations.
If the startup drive is in good shape, your system Disk Utility should see it. Under the Disk Utility window, select your preferred startup disk. Click on it to mount. By now, your new startup disk should be accessible by your operating system.

Lift the lid of your MacBook Pro or MacBook Air to turn it on, or press Touch ID. Every time you start up, restart, or log out, you need to type your password to log in to your user account. After setting up Touch ID, as long as you're logged in, you can use your fingerprint instead of typing when you're asked for your password.
With Touch ID, you can also use your fingerprint to make purchases from the App Store, Apple Books Store, and iTunes Store, as well as many of your favorite websites using Apple Pay.
MacBook Pro with Touch Bar
On MacBook Pro models with Touch Bar, the Touch ID button is on the right side of the Touch Bar at the top of the keyboard.

How to set up Touch ID
Make sure that your finger is clean and dry.
Choose Apple menu > System Preferences.
Click Touch ID.
Click the plus sign to add a fingerprint, type your user account password when prompted, then follow the onscreen instructions.
Use the checkboxes to select the Touch ID features that you want to use on your Mac.
Tips for adding fingerprints:
Place your finger on the Touch ID button — but don’t press. Hold it there until you're asked to lift your finger.
Lift and rest your finger slowly, making small adjustments to the position of your finger each time.
Add up to three fingerprints.
You can also delete fingerprints:
Hover the pointer over a fingerprint. A delete button appears.
Click the delete button, then enter your password to remove the fingerprint.
Use Touch ID to unlock your Mac
After you set up Touch ID, you can use it to unlock your Mac. Wake up your Mac by opening the lid, pressing a key, or tapping the trackpad. Then place your finger lightly on Touch ID to log in.
You must type your password to log in after you start up, restart, or log out of your Mac. When you're logged in, you can quickly authenticate with Touch ID whenever you're asked for your password.
You can also use Touch ID to unlock these features on your Mac:
Password-protected Notes
The Passwords section in Safari preferences
System Preferences If you have FileVault turned on, you must type your password to unlock the Security & Privacy pane and the Users & Groups pane.
If multiple users set up Touch ID and log in to the same Mac, they can use Touch ID to switch accounts. Just press Touch ID, and your Mac switches to the logged-in user account associated with the fingerprint.
Make iTunes Store, App Store, and Apple Books Store purchases with Touch ID
Use Touch ID instead of your Apple ID password to make purchases on your Mac:

Click the buy button for something you want to purchase. A Touch ID prompt appears.
Place your finger on Touch ID to complete the purchase.
You might be prompted to enter your password on your first purchase or if you've made changes to the fingerprints that you've enrolled in Touch ID.
Use Touch ID for Apple Pay
You can make easy, secure, and private purchases on websites using Apple Pay on your Mac. Apple Pay never stores your credit or debit card information and never shares it with the merchant.
Apple Pay is not available in all regions.
Set up Apple Pay
On Mac notebooks with Touch ID, you’re prompted to configure Apple Pay during setup. If you don’t choose to set up Apple Pay when you first start up, you can set it up later in the Wallet & Apple Pay section of System Preferences. You can also check your transaction history and manage your payment cards there. For example, you can add or delete cards and make updates to contact or shipping information.
You can add payment cards to only one user account on your Mac. If you set up Apple Pay in your main user account and then log in under another account, Touch ID and Apple Pay are unavailable. In this situation, you can use an eligible iPhone or Apple Watch to complete Apple Pay transactions that you begin in Safari on your Mac.
