Q: System wont boot after OS X 10.11.2 update

According to the article, you need to the the OS X installer from the App Store.  I don't see an OS X installer to download from the App store.  Am I missing something?

sorry to ask rather simple questions..

I made a bootable drive, but the reinstall OS X option defaults to Network.

Is there a way to reinstall from the flash disk?

Click to Download OS X El Capitan. What you get is an installer. Before you actually install, make a copy of it (because if you just install it will delete itself after it's finished).

Connect the flash drive, start your mac holding down the Option key (a.k.a. as the "Alt" key). This will let you select your installer flash drive as the startup drive, and you can use it to install or to use the utilities in it.

Thank you Luis.

It seems I am in a real pickle.  Having tried this option too, the progress bar is stuck close to 100% and it stays there forever. 

I may have to take your advice and use Time machine back up.  Unfortunately my TM back up is about a month old and there is significant work that is probably going to be lost.

Thanks to everyone on the community for help.  It was a big mistake installing this update.

Quoting a previous post - "Apple has dropped the ball on this one ....."

Before you TM back to your back up, use the Target Disk Mode to pull your important data out first.

good point.  I will definitely give this a try first.  Thank you for your good advice.

Thank you, Luis.  Brilliant!

I’m on a perfectly healthy mid-2013 AirBook, maxed-out, but otherwise plain vanilla (no haxies or such), which I had updated to 10.11 without any problems. (I’m backed up with a bootable clone plus Time Capsule, so my data’s safe.) I couldn’t update to .1, and now, not to .2, either. Since the problem with .1, I’ve done - repeatedly - everything I could think of to fix it (repaired with DW and TTP, tried everything relevant listed here <http://macs.about.com/od/MacTroubleshootingTips/tp/Top-10-Troubleshooting-Tips-F or-Mac-Startup-Problems.htm>).

Since I don’t want to stop working on my Mac while updating, I’m attempting to update the clone, on an external disk via Firewire 800, using the 10.11.2 combo update which I have on a flash drive (I had tried .1 directly on my AirBook). The result: progress bar fills - creeps more and more slowly as it nears the end - to what looks like 100%, and stays there. Nothing more happens, even waiting overnight.

Curiously, my wife's slightly newer AirBook had no problem at all with .1 - I haven't tried .2 yet.

I’ve never had a problem like this since I began using Apples, in 1984. It’s surely a software problem, not hardware or disk space. I don’t know how many users worldwide are having this problem, but judging by what I read, it’s probably only a small percentage, not large enough for Apple to attend to it. Still, I don’t know what those of us who are affected can do. Apparently, Genius Bar people can’t help, either. I’m really dismayed and angry. Will I be stuck with 10.11 forever?

I realize this may be overdoing it but, really, I have tried for months to get a backup boot disk to no avail.  The article and your suggestion concerning how to keep the OS X install file from disappearing finally worked.

I was  trying to use disk utility before and it just didn't work.  I think it probably worked with past versions of OS X but is just not available any longer.

Thanks, Luis!!!!!

By the way, is there any reason I can't add files to that memory stick (it's huge, plenty of room).

Thank you for posting the solution.

This may well be valuable information to other people having problems.

Antivirus software is not needed on the mac and often causes problems. It turns out that Apple did NOT drop the ball on this one :-)

I was using Avast, not Norton, but removing (uninstalling) it entirely (not just turning it off), along with CleanMyMac and the Kensington Trackball driver (for some reason, I suspected those) didn't solve the problem: still no boot-up. From where I sit, Apple still dropped the ball.

The problem with stuff like CleanMyMac is that even if you delete it, you probably already used it and damaged your system.

If users fall for this sort of crap it is on them, not Apple.

I can't argue with you definitively, but I've been using it since it was a pup, and AFAIK it never caused a problem before, and certainly never anything this destructive. Besides, CMM is on my wife's AirBook, too, but that Mac had no problem with this update.
