Question: mac OS Hi Sierra. Jammed with less than a minute for over 24 hours
Help my computer is working but the update screen is jammed. I have slow internet so this update took a while to update and I had to keep restarting the download but now I have the update screen taking the installation will take less than a minute and that has been for more than 24 hours. What can I do. Can I delete the High Sierra from Applications and start again using faster internet.
MacBook, OS X Mavericks (10.9.2)
