I've been poking around Catalina for the last month or so on a 2012 MacBook Pro that I keep around for testing. I didn't do much with it however, just set up some programs to make sure they would work. All went well so I purchased a 2020 Mac Mini and am in the process of actually using it. I'm aware of the double drives, Mac HD and Mac HD-Data. My question is, what are considered the best practices for setting up files and folders? For the last couple of decades I've kept various files organized in folders in Mac HD. In Catalina, the permissions for Mac HD don't allow that. It looks like perhaps I could change the permissions to what I'm used to (I haven't tried it yet) but I assume that's not the preferred way of doing things. Should I create a folder on the Desktop and use that to store files the way I've always done in the past in Mac HD? Or, is there's a proper way to do this in Catalina that I'm not aware of? I'm not a newbie but could use a little help getting started with the different way Catalina operates. Thanks.
