My iMac desktop has Flash/SSD (late 2019).
Previously, I had an iMac with just the standard hard drive (not Fusion or SSD). Whenever a new OS was released, I would do I clean install i.e. backup my Home Folder, secure erase the drive, install the new OS, and then migrate my Home Folder contents (as per instructed).
I like the idea of cleaning up any straggly bits and take the drive back to its factory condition before installing a new OS. Is there some form of similar Clean Install routine for my current hard ware? Is that something which no longer can be done OR no longer is necessary?
