The latest OS by Apple moved all of my folders into the Security folder. Now all my folders which were on root are not able to move on root anymore and it gives the message: mkdir: myDir: Read-only file system.

Before my folders were on /. For example /Developerment. It is not there anymore. I did find my folders under Security folders but can't copy on root now.

What should I do?

  • Can you please clarify "moved all of my folders"? When you say 'all', which folders do you mean? Or do you literally mean all folders? Otherwise, macOS Catalina by design creates a read-only partition for the system to further protect/isolate it from user data.

  • @Monomeeth I mean the Custom folders I had created like Videos, Development etc. They were now /. Now I can't keep there as it is readonly. Where can I keep those folders now?

  • Ok, it'd be good if you could add those examples to your question and also include where it was these folders were located previously. By the way, do you have a backup of your data (Time Machine or otherwise)?

  • @Monomeeth My data is all intact.

  • Shouldn't have ever been off the root anyway. Put them in your user folder. Oct 9, 2019 at 22:16
