I've installed el capitan on my 2012 mac mini and after the install everything is running great. Except, when I shut the machine down it won't re start!
It gets to the apple logo and progress bar, but the bar doesn't populate at all.
I tried leaving it for half an hour to see if anything would happen, but it didn't!
Any help would be greatly appreciated.
- Try resetting the SMC and NVRAM/PRAM
Intel-based Macs: Resetting the System Management Controller (SMC)
- Try starting in Safe Mode
OS X: What is Safe Boot, Safe Mode?
- Boot to Recovery and repair the startup disk
tried both those things you suggested lllaass, unfortunately it didn't help.
What exactly happened when you did what I suggested?
the machine re started but would not proceed.
had to re install the software.
when the software install finishes it re starts as part of the process, and that always starts ok,
but when I try to re start in the regular way it still gets stuck!
Did you try booting to Recovery, formatting the startup disk and then installing EC?
I have no Idea how to do that. It sounds scary!
It is only scary since the disk gets erased.
I previously told you how to boot to Recovery, In Recovery there is a Disk Utility and an option to install OSX.
yeah, that's how I've been re installing.
haven't wiped the disc though.
If I make a time machine backup to an external drive, then, go to recovery, wipe, install EC. will I then be able to recover from time machine without bringing what may be a corrupt install of the os back?
Just restore data, do not restore apps, settings or the OS itself.
However, since you say you can't boot you can't make a TM backup.
If you can boot to Recovery you can copy/clone the internal disk to an external disk via disk utility. See:

The after you format and reinstall EC you can hopeful copy data from the external disk.
I had the same problem, but I found the reason and solved it.
At my mac I had installed virtual box and logitech control center.
After uninstalling both (you have to delete the logitech kext files in system library folder) every thing is working fine now!
I'm pretty sure that I don't have either of those installed but I'll check.
From what I have read, it looks like it is going to be a kest problem, but how I'd find out which one is causing the problem? I don't know.
Thanks for the help though, it's very much appreciated.
Try what I said in my previous reply
Ok.
I have managed to make a time machine backup, wipe the drive, installed El Capitan.
after going through the setup all seems to be working.
Now, What do I need to bring in from my backup? and where do I put them?
My iTunes library is on an external drive, but even though I've told iTunes where it is, none of my albums are showing!
I have noticed that the new os has created it's own iTunes files, do I need to get rid of those?
Sorry to be such a pain, but I'm feeling a bit lost.
Is the library on the external disk correctly identified in iTunes>Preferences>Advanced?
Is the external drive connected and can the library be seen in Finder?
I had exactly the same problem on my MacBook Pro laptop. Re loaded El Captain (EC) OS X. Problem back. Finally spoke to 2nd level Apple support. He helped me reformat disk and re install EC. Now laptop works fine. Big problem with this, is to the install all the programmes again, lots of hassle, looking for licence keys etc, took me a whole day.
Yesterday got back home. Installed EC on iMac desktop. Same problem, exactly the same. At the moment I don't have the time to format the hard disk, so downloaded EC form the server. Takes ages, but at least all the programs and data are intact. Wont turn the power off. Later when I have more time, will have to flog through the re-formatting and re-loading all the programmes. Dreadful prospect.
Any way we can highlight this to Apple, and encourage them to release a fix?
