All directories accessed by mongod must be writable by the user with which you start it.
By default mongod uses /data/db to store its data. In your case, I suspect your username is kevinturney, so /data/db should be owned and be writable by user kevinturney.
That is right.In Macos /data/db access is removed
In the link you shared it asks you to create the dir under /System/Volumes
Did you try that?Once dir is created you need to update the new dirpath in your mongodb config file
Creating the dir in System/Volumes according to the article did not work for me.
When I started the daemon: mongod --dbpath=/Users/kevinturney/data/db and in another terminal tab, mongo, the processes started and the shell opened with no problems. With this configuration am I in good shape or are there problems with where I placed my directories that I don’t know about?
