My rMBP is a brick now after upgrade to 10.11.2.
It will start up, but no response to dock items, folder icons are generic. Apps will not open. Truly a brick now.
Caution.

IIt's a brick, using iPad now
Determine if you can start your Mac in "Safe Mode":
Did you have any AV or so called "cleaning" software/apps installed?
Did you have FileVault turned on while updating (should turn that off first).
Before trying the next steps, I hope you have a backup (especially if you can't access anything).
If Safe mode does not help, use recovery (Command + R) to reinstall the OS over the top of what you have; or, a more radical step: use Internet Recovery (Command + Option + R until you see a progress bar) to connect to Apple's Servers. Once you see the Utilities window, use Disk Utility to erase your drive; when done, choose to reinstall the OS. At that point, it should reinstall the original OS version.
FWIW, such problems are usually the result of having things installed that are not compatible or wreak havoc on the system and/or installer - usually third party.
I have nothing installed or running you mentioned. Reinstalled using recovery. Things are worse. Most dock icons do not appear, Any apps that appear when clicked on gives dailog that app is damaged.
Evertything was running well until I tried to upgrade.
If you don't already have a current backup, please back up all data, then reinstall the OS.* You don't need to erase the startup volume, and you won't need the backup unless something goes wrong. If the system was upgraded from an older version of OS X, you may need the Apple ID and password you used.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
If you installed the Java runtime distributed by Apple and still need it, you'll have to reinstall it. The same goes for Xcode. All other data will be preserved.
*The linked support article refers to OS X 10.11 ("El Capitan"), but the procedure is the same for OS X 10.7 ("Lion") and later.
If you could post the instructions about the back up of a box that is not fully functional, I would appreciate it. My upgrade worked fine on three Macs but on one mac mini (late 2012) I can't run any apps and the dock is useless. So I may need the back up procedure. No AV or FileVault in use - same as OP. Thanks.
The "instructions about the back up of a box that is not fully functional" is to back it up before it becomes "not fully functional"; a backup taken while "not fully functional" will likely restore the malfunction along with everything else.
Same issue here, iMac 27 late 2013. 😠
My impression is, that 10.11.2 has an issue with permissions.
Finder is very slow, does not show all files, no app can be opened (pop up notice: might be broken).
Save boot does not help.
When trying to boot into single user / terminal and performing permissions repair, it always says: permission denied, read only!
Strange thing: my wife's account works properly.
1st attempt was: FileVault on, update from 10.11.1 to 10.11.2 via App Store --> everything is broken.
2nd attempt after time machine restore: FileVault off, 10.11.1 to 10.11.2 via combo update downloaded on Apple page --> same issue.
2nd time machine restore is ongoing, will ban 10.11.2 now! Apple really has an issue with OSX for years now, fix it!
By the way: please also fix your USB issue in El Capitan, my eyetv VCR is still broken!
Best regards

Unfortunately, we are not Apple - we are all other users, so we cannot fix anything like that. You need to contact Apple.
You should never have FileVault enabled when doing an update.
Permissions are not dealt with in the background; they are no longer available to the user to 'fix'.
If there are multiple issues (too many to try and fix), back up your files, and use internet recovery (Command + Option + R) to then erase your hard drive and reinstall the original OS. Remember to turn off FileVault and unplug any peripheral except keyboard and mouse.
All updates bevor worked properly with FileVault on and as you can read above, FileVault is not the issue.
And users can still repair permissions via terminal, you can find several post regarding this topic.
When it says for approximately 100 pages, permissions wrong, but cannot fix it due to read-only as sudo, then there is an issue.

I prefer not to employ hacks and use the OS as intended, although I am well aware of the options out there - thank you.
Good luck.
You will have to contact Elgato for support with their products. Try this:
Apple cannot help with products they did not develop and for which they have no control.
And on the German page Elgato says Apple broke the USB stack.
FIts to to the complaints of a lot of musicians regarding their USB peripherals not working anymore with 10.11.x
If you used the regular update from the Mac App Store, let me recommend instead downloading the combo update (osxupdcombo10.11.2.dmg) from the Apple Support Downloads (https://support.apple.com/downloads/). I never use the simple update and have avoided problems like yours for many years.
Caution 10.11.2
