El capitan freeze during install

Thanks very much for this post Denbee. I was about to give up and restore from my Yosemite Time Machine back up.

This is the only suggested solution that worked for me. But as I couldn't log in with safe mode I had to do this in single user mode but it worked just as well.

I just wish I'd found this a couple of weeks ago when my daughter was updating her MBP 17". I had to do a back up of all her data in single user mode and do a fresh install of El Cap.

You can try an internet recovery boot, as stated at OS X: About OS X Recovery - Apple Support

You can try stopping the MBP with the power button. Once it is stop for 20 seconds or so power it back up again and see if that helps.

i am having precisely the same proble,

Worked! Thank you! Looking over many threads, it looks like you are absolutely right and the problem is a .kext

Thank you!
I have been having this trouble every time I tried to update since late 2013. I am so happy I can finally update my notebook without crossing fingers every single I try. Thanks again!

Just follow the instructions Denbee left on this post. Worked for me 😉

Doesnt work because I can't even get it to boot in safe mode, nor recovery mode.

Mine freezes up going into safe mode too. Any other advice?

I called but was told that since my MacBook Pro was not longer under warranty then there would be a charge for the service. But maybe it is worth it to try again.

If you have access to an Apple Store, your appointment for an evaluation at the Genius Bar is free, in warranty or out.

Any repairs you decide to have them perform are at flat rate, no surprises.

I can boot in Recovery Mode. But it seems like it is in Safe Mode that I need to be to fix things.

In recovery mode, you can do a Disk Utility ( Repair Disk [directory]). This may improve things enough to get to Safe Mode.

If it is freezing in safe mode that would tend to indicate a problem with the installation of El Capitan. Try reinstalling El Capitan again and see if that helps.
