El Captain frozen at progress bar

[TracySW]

Thursday night I downloaded El Captain but has frozen my Mac mini on the progress bar and I cannot do anything. It reboots itself every five minutes or so but always ends back on the progress bar which is about 3/4 along.
I read a few hints on the apple site but none helped. My PC keeps rebooting itself but goes straight to the progress bar. I cannot access anything on my desktop and the command keys etc, won't allow me to do anything. One time I held down the com-s as soon as I turned the PC back on and a message flashed across the screen " this PC has restarted due to a panic" something like that anyway but it just goes back to the screen with the progress bar.
I don't know what else to do! Im not that savvy with computer data.
Would appreciate your thoughts and help.
Regards

I had a similar issue with my update. The answer was to switch off the computer with the hardware button. Restart it in recovery mode (hold Command + R) until it shows the Apple logo and then re-download and reinstall from the menu options that you get. You could also, if you prefer, restore to your previous system from a time machine back-up.

Thanks for your reply Torchy, I just tried your suggestion a few times but it is still frozen with the same issue. Any other suggestions (besides a hammer - lol)

I had the same issue on two of the for machines I upgraded. The only solution that worked for me was to wipe the disk and do a clean install. It was a pain but in the long run I have a fresher system now

I ended up taking it to the apple store and it cost me $120 to fix grrrr! Its been having issues with safari since which is frustrating. It goes to a webpage fast (most of the time) but when I click on a link on any page it takes ages to load and usually server times out. If I reload the page sometimes it loads but more often than not it doesn't.

I just updated my last machine that was giving me problems. It is a MacPro 2008 I was never able to update the existing OS and was dreading a clean install because of all the applications I have installed. I installed a fresh copy of El Captain on a second drive and did all the updates taking it to 10.11.2 after that I used migration assistant to copy over the Yosemite disk and all the apps, machine works fine now.
