The Recovery Mode on Macs is where you can find various utilities and apps. From here, you can reinstall macOS, which, in some cases, can fix the issue of the Macintosh HD not showing up on Mac. Here's how:
- Follow the abovementioned steps and enter macOS Recovery Mode.
- Select the Reinstall macOS option and hit Continue.

- Follow the steps from the 2nd solution to enter the Recovery Mode.
- Select Disk Utility and hit Continue.
- Choose your problematic HDD and run First Aid once the app opens.
- You can also Erase, Partition, and Format the drive if First Aid doesn't work.
Options from Step 4 erase your entire drive, so only use them as a last resort.
Fix 5: Take Your Drive to a Professional Repair Store
Even though they're inside the Mac, internal hard drives can still be physically damaged through falls, shocks to the system, and even stronger magnets. Therefore, it might be time to contact professional repair services if you've dropped your Mac or heard an unpleasant hard drive sound.
Such a solution can be costly depending on the culprits behind the issue of an internal hard drive not showing up on a Mac, but it can help repair broken HDDs and recover your vital data.
Fix 6: Replace Your Drive
Although accidentally deleted hard drives, corrupted HDDs, drives with the wrong format, outdated drivers, and invisible ones can be fixed through software troubleshooting steps, physically damaged drives must be replaced.
If your Macintosh HD is beyond repair, not even a professional repair store can help, and you will need to replace your HDD by purchasing and installing a new one on your Mac.
How To Fix Internal Hard Drive Not Showing Up on Mac But Boots
Compared to a Mac that's not recognizing the HDD and not booting, you undoubtedly have a much lesser issue if your internal hard drive is just not showing up in Disk Utility, but your Mac is booting. In those instances, the following solutions can help resolve the issue and make your hard drive visible again.

If you follow the steps carefully, you'll have nothing to worry about. So, let's dive right into this fix.

Fix 5: Update Drivers
Like with a Windows machine, drivers can create various Mac issues. Therefore, you might need to update them if your Mac doesn't recognize the internal hard drive.

You can also click More Info to learn about other updates. Similarly, checking the box next to Automatically keep my Mac up to date will automatically download and install future updates.
