Hi greg, why not start the machine up in to recovery mode using cMd plus R then under utilities go to disk utility and find the internal drives macintosh HD volume and eraise that.
Then back to utilities and install If you have more than one volume called Macintosh HD then use a USB Flash drive to start the machine on to and carry ou the same processes except rather than eraising the drive volume under the view menu show all volumes / devices and the actuall drive not volume in your machine Do a partition on it. This will wipe everything all volumes and including the recovery volume / partition, Then you can go back to the utilities on the flash drive and install the os from scratch.-----Original Message----- From: macvisionaries@googlegroups.com <macvisionaries@googlegroups.com> On Behalf Of Greg Wocher Sent: Saturday, 11 January 2020 6:25 AM To: macvisionaries@googlegroups.com Subject: Another clean install for me and a question Hello, I discovered that for some reason in my last clean install I ended up with two macOS data volumes instead of just one. I think this is what is causing some of my weird issues. So I am going to do another clean install this weekend. Hopefully this time I will get it right. I wonder if I should erase everything including the macOS system volume? This way there is nothing on the computers hard drive at all.
