MacOS storage does not have the partitions that Windows 10  has. However, you can create drives in storage, and this is somewhat similar to having a partition.

The disk is where the operating System is installed, and when you access it in the Finder, it will be displayed with whatever name is assigned to it, and you can rename the macOS disk at any time.

Rename the disk in macOS

You can rename any disk attached to the Mac, and there is a tool for renaming the System.

Disk access tool

• Press Command + Spacebar at the same time to open Spotlight.
• In the new window, enter Disk Utility.
• Select the program with the matching name.
• If the disc is not connecting, make the connection. Of course, this is not necessary for the internal disk.

Now that you have opened Disk Utility, you can rename the disk by following the steps above.

• Click the disk in the right column.
• Select Rename from the menu.
• You can edit the disk name on the right page.
• Enter a new name and press Enter to save.
• The disk name will be changed.

Note that renaming the disk will not erase the data on it and will not cause any problems.

Limitations

Disk Utility can be used to rename internal and external disks connected to the Mac, but the tool we use is the macOS tool. If the disk you want to rename is not formatted correctly (APFS or exFAT), it is not possible to rename it.
For example, if your disk is formatted on an NTFS System, you must first modify its File System, which will result in data loss. If you want to rename the NTFS disk and do not want to back it up, you must use a Windows 10-based System to do so.

Conclusion

Renaming a disk helps make it easier to identify. You may not always be able to remember the available disk space, or if it has a generic name, it will always be detected in the Finder.
The real name, not the default home name, can be effective in identifying the disk and making it easier to manage the disk.
