<p>Apple took system protection to the next level in macOS 10.15 Catalina by splitting your normal boot volume into two pieces. It appears like a single volume on the Desktop, but it’s really two: one is labeled with the volume’s name, while the other has “- Data” appended to it.</p><p>The <a href="https://support.apple.com/en-us/HT210650" rel="nofollow">new main volume is read only[/url] and contains only operating system files.
