High Sierra installation freezing
I'm trying to upgrade from 10.12.6 to 10.13.6 on a Mac mini (Late 2014) 2.6 GHz Intel Core i5 Memory 8 GB 1600 MHz DDR3. I have slow broadband access, but I don't know why it freezes when there's only about 15 secs remaining to install. I've already tried installing on safe mode.
Mac mini, macOS Sierra (10.12.6)
