I need create a new folder on the "Macintosh HD" drive and I have macOs Calatina
With previous OS systems, I was able to create folders under "Macintosh HD" but recently I upgraded to Calatina and the system is not allowing me to create a new folder in this location. There is a software that I use for work that needs two specific folders to be added in this location so I can't work around creating the folders elsewhere on the mac. I read in another forum that there may be a way to change permissions for the HD to be able to add a folder here but I was not able to find these steps in my research on this.
MacBook Pro 13", macOS 10.14
