Big Sur Cannot Be Installed on Macintosh HD: What to Do

Are you facing issues with installing Big Sur on your Macintosh HD volume? If it's an encrypted APFS formatted volume, you'll need to unlock it first. Additionally, if you see a Macintosh HD-Data (or macOS - Data) volume, please select that one instead.

To troubleshoot the issue, run the following command to launch iBoysoft Data Recovery for Mac through iBoysoft Server. Make sure your Mac is connected to the internet at all times.

Reboot your Mac and boot it into macOS Recovery mode. Here, we recommend using iBoysoft Data Recovery, an excellent product that can help you recover data from unmounted volumes.

If any important files are stored on the Mac HD, it's essential to recover them from the unmounted volume first to avoid further data damage. When you encounter the Macintosh HD not found in Disk Utility or Macintosh HD not mounted issue, be aware that there is a risk of data loss.

To recover data from an unmounted Macintosh HD, follow these steps:

1. Reboot your Mac and boot it into macOS Recovery mode.

2. Check if the internal hard drive of your Mac (disk0s2) or the Macintosh HD is not mounted. If so, you'll see a message indicating that macOS cannot find a mount point to read and write the Macintosh HD.

If the Macintosh HD is not showing up in Disk Utility, it means that the drive is not available for the operating system. However, some users report that they can't find Macintosh HD in any of these places, with no startup disk on their Mac.

To find Macintosh HD on your Mac, look for it in the Finder's sidebar as well as that of Disk Utility. You can access all your user account files stored on Macintosh HD and perform actions on the drive such as adding APFS volume, deleting APFS volume, and erasing the whole drive.

Macintosh HD is usually the default startup disk on your Mac if there is no second drive installed. If you're experiencing issues with Macintosh HD not being mounted or showing up in Disk Utility, here are some troubleshooting steps to try:

1. Check for any issues with the APFS volume.

2. Run a diagnostic test using Disk Utility to identify any errors or problems with the volume.

3. Try resetting your SMC and NVRAM settings.

If none of these steps work, you may need to seek professional help from Apple support or a third-party data recovery service to recover your important files.

By following these steps and troubleshooting tips, you should be able to resolve the issue with Big Sur not being installed on Macintosh HD and recover any lost data.
