I used csrutil disable to turn off System Integrity Protection and deleted some unused pre-installed apps before macOS 10.14. Recently, I upgraded to macOS 10.15 Beta (19A487l) and found this way didn't work anymore. My admin account only has Read-only access for pre-installed applications.

The /Applications in Terminal is actually /System/Volumes/USER-Data/Applications.

➜  ~ ls /Applications       
Alfred 4.app           Safari.app             Utilities
Google Chrome.app      ShadowsocksX-NG.app    Visual Studio Code.app

I don't have write access to /System/Applications.

➜  ~ sudo rm -rf /System/Applications/Stickies.app
...
rm: /System/Applications/Stickies.app: Read-only file system

I also cannot change the privilege from Finder -> /System/Applications/Stickies.app -> Get Info -> Sharing & Permissions, it says:

The operation can’t be completed because you don’t have the necessary permission.

I've read Is it possible to delete the "useless" apps pre-installed on my Mac? and chflags didn't work either because of Read-only.

How can I access to the "real" system account or is there the other way to delete or hide those applications?

Thank you.

    where is the duplicated question/answer? – evandrix Nov 1 '19 at 16:16

    The arrival of Catalina (10.15) made all previous answer obsolete, so I think this is a valid question and not a duplicate. If I'm mistaken, which is not impossible of course, then I would like to find the duplicate question/answer as well (couldn't find it at SE). – Hanzaplastique Nov 3 '19 at 13:01

    I'm astounded this question is closed. I have this exact problem, and while the linked question is related, it is not at all helpful for someone who just wants an answer! I found a solution in a reddit thread. When you log back in (after disabling SIP) you need to sudo mount uw / then you can delete the apps (at least you can using AppCleaner).

    That should be sudo mount -uw / – Phill Apr 9 '20 at 2:35
  • @Phill Awesome! It works on 10.15.4 – Will Chang Apr 18 '20 at 13:15
