I am really resisting the urge to upgrade from 16A319 to 16A323, but I am weakening.
My plan all along has been to wait for 10.12.1, and then upgrade from 16A319.
Anyway, a few refreshers, if you will:
1. Being as I already have 16A319 installed on my iMac, once I make the 16A323 USB drive installer, I do NOT need to reformat my iMac's internal drive where I will be installing 16A323, correct? In other words, I do not need to do a clean install. I can just install 16A323 on top of 16A319, right?
2. If I can install 16A323 on top of 16A319 on my iMac's internal hard drive, will it result in my losing all of my personal files from my Home folder, my Applications folder and elsewhere, so that I will have to migrate everything again from my backup drive like the last time?
Or will personal files be preserved this time?
Point number two is the main reason why I have resisted upgrading from 16A319. It takes almost seven hours for me to migrate everything.
Thanks again for your hard work with all of this.
