HELP - Thrown into Unix Console Mode after Security Update

After installing latest security update using Software Update, I rebooted and got the usual Mac OS X login screen (choice of 3 users on my iMac). After clicking on my user icon, the screen goes briefly blue, then black, and white writing appears with "Darwin/BSD (Taisa) (console)", followed by "login:" prompt. I can log in into the unix environment, and find that all is well with my files, except I have no GUI.
I have run the Disk Utility by booting from the OSX Install Disc, repaired permissions, and repaired the disc, but problem remains. A look at /var/log/system.log (last 40 lines of which is copied below) indicates that configd crashed, and so did AppleFileServer and SecurityAgent. Any ideas of what is going wrong and how to fix this?

To answer your question, the messages:
IOResources: match category DigiIO exists
SetCryptoKey T: len 32, idx 0
SetCryptoKey R: len 32, idx 3
SIOCPROTOATTACH_IN6: en0 error=17
all appeared in old logs when the system was healthy. The old logs also show that configd occasionally crashed; however, they never show SecurityAgent or AppleFileServer crashing - here are the corresponding logs:

Help! After Security Update, Mac starts in UNIX!

I'm really stuck with this one. I installed the new security update last night, and when the computer restarted, it started up in UNIX console mode; Said "Welcome to Darwin!" I don't want to go to Darwin!
I don't know anything about the UNIX system, so all I've done is restart a few times, and tried a few things from the Missing Manual: "safe mode" restart didn't work, I even restarted into "root user"? (sorry, I know I sound stupid) and tried a disk repair using "fsck." It says my disk is fine. I don't have a second hard drive.
I'm willing to reinstall Tiger, but how can I get the CD in the darn machine from UNIX?

Veronica
what is the UNIX command for restart or shutdown? Is there a page somewhere that lists commands?
Um, reboot and shutdown -h now. You can read all about them with man reboot and man shutdown. You need to know the name of a command before you can access its documentation in the man page. There are ways to get a list of commands, but they are not at all helpful.
If you follow my instructions, you won't need any commands other than the ones I post, but by all means read what each one does by looking at its man page.
BTW, your 10:30 am translates to my 6:30 pm, so do allow for this in watching for replies

Please help, my ipad mini is gone into to recovery mode after updating to iOS8.1 and even though I restored it through iTunes it still will not come out of recovery mode

please help, my ipad mini is gone into to recovery mode after updating to iOS8.1 and even though I restored it through iTunes it still will not come out of recovery mode

Try a Reboot press & hold menu button & power button hold both down until you see Apple Logo you will not lose any data. But you may need to do this more than once. I never use PCs for software upgrades or downloads I always use wifi had no problems with iOS 8.1 B sydd

IMac randomly booting into "safe boot" mode after a clean installation of OS X Lion 10.7 (??)

Is anyone else having problems with their Mac (running a clean installation of OS X Lion 10.7) randomly booting into "safe boot" mode after a restart or shut down?
(Indicators being: seeing the login screen even when "automatic login" is enabled, the proper video drivers not loading - indicated by laggy desktop animations, WiFi not working properly, Menu Bar icons that normally show - not showing, etc.)
**Note: I migrated from a Snow Leopard Time Machine backup, but did not import "Settings". I thought this would be the best way to keep from encountering any issues with 10.6/10.7 incompatibility.

Found this answer from another user. THE EXACT THING HAPPENS TO ME:
Its really annoying Apple hasn't fix it.
=================
I think i got it :
The progressbar while booting ( booting in safe-mode ) came from the wireless keybord and is reproduceable.
At evening I shut down my iMac an put off my mouse and keyboard. To startup I put on the iMac and immediatly after I switch on keyboard and mouse. In tihs case the keyboards sends some event wich leads to safe-mode.
Know I wait until I switch on the keyboard. In my opinion this is a bug, i can live this way but i hope it will be fixed.
I will know take a look at it while not switching off the keybord, power consumption should be acceptable

Applications not responding apparently after Security Update 2007-009

Mail, iTunes, Skype, MSN Messenger, MainMenu, Emule, Safari and god know what else aren't responding after Security Update 2007-009.
Hi,
I recently purchased a new phone that does not work with macs, so I bought an application from Feisar to make it work. The application isn't freeware, so I think it is very unlikely that it bogused my system. Anyway, I installed the software, but only afterwards noticed it didn't work for my phone model with the USb interface, only through bluetooth, which I don't have. Moreover, and, in my opinion, more importantly, I also downloaded and installed security update 2007-009. After the update, I mandatorily restarted OS X and instantly noticed Mail, iTunes, Safari, Skype and Messenger not working. I click on them on the dock, they bounce (usually once, but it has occured to be more) and nothing happens. I don't get the little arrow below the icon. I see the applications in the applications folder, so they are not missing. I searched and searched on the internet and, apparently it is, to say the least, herculeanly complicated to downgrade from a software update. I tried to repair permissions and it didn't work. I tried the apple hardware test and everything came out perfect. I restarted many times and the same keeps happening.
So I wasted half my day yesterday trying to fix this, looking into forums and trying to talk to people about it and there it absolutely no answer. Yesterday I installed the programs necessary to sync my phone in my wife's macbook and nothing bad happened. So I'm guessing it isn't about the phone plugins I installed. I've tried to download combo updates but they crash as soon as I try to install them - I even tried to install a 10.4.10 update.
This is the error message I get:

I put part of in on google to check if there was anybody discussing anything related and someone suggested - bizarrely enough - updating adobe reader. I did it just in case and, of course, it didn't work. I repaired permissions a million times already, I rebooted in safe mode, I scaned the computer with apple jack (which reapetedly said that I had a "fan failure!"), I verified the disk with diskutility - which showed nothing. I tried downloading an anti-virus (ClamXav), but I couldn't open it also, I trashed my prefs, I deleted all internet plugins, but still.... nothing.
The most likely line to follow here is the "fan failure" message in apple jack. I looked inside my g5 and all fans except for the one close to the Hard Drives aren't spining. I'm not sure this means they aren't functional or whether the temperature isn't high enough for it to be turned on. Temperature must be around 26-28 degrees Celsius today. There is nothing on the internet about that fan failure that's close enough to my case.
I'm about to quit and take it to the very expensive - yet reliable - authorized tech support apple has in Rio. Any ideas, anyone?

Maybe it is a security update thing! I have had similar troubles with my CS2 and other simple apps like TextEdit not opening, just doing that single bounce... I have tried EVERYTHING and now, after reinstalling my entire system, have lost access to my own user profile.
I'm assuming you have tried starting up with your original system install disk in the computer, while you turn it on, hold the option key, it will allow you to run another hardware check, as well as to do an archive install if it comes down to that.
good luck, please let me know if you find out something else that might be causing the problems... i've noticed that alot of mac threads have similar probs listed.

Rosetta Problems after Security Update 2012-001

My crack team of sys admins and I have devised a method for resolving some of the issues regarding the Security Update 2012-001 and Rosetta.
http://www.educate-it.org/content.php?130-Rosetta-Issue-after-Security-Update-20 12-001
Click this link for an Installer that will revert the files necessary for some Rosetta apps to run after the Security Update. This is a band-aid and is only recommended in emergency situations. Apple is currently working on a fix, but until that happens, we are stuck with reverse-engineering their update. I hope this helps those in distress from this update.

Backup files off the computer (not TimeMachine) and disconnect.
If you have TM, or a option key bootable clone use that to erase and restore from.
If not, c boot off the 10.6 disk, use Disk Utility to >Repair Disk and Permissions, (do not format or erase!!) and simply re--install 10.6 from the disk. Note: Does not touch your files and most programs, but backup your files regardless.
Note: If Disk Repair gives a error that is not repaired, then you have to consider erasing the drive (with Zeros) and try reinstalling 10.6 fresh or replacing the drive.
Reboot and log in, update to 10.6.8, it should not include the security update at this time (second pass it might show) because it was just released and they might need to pull it. (they need to pull it)
When you reboot, make sure to reinstall any programs that installed kext files into OS X, you'll know, they won't work.
If you get gray screen, hold the shift key and update your installed software so it's compatible with 10.6.8.

Kdcmond could not launch, after security update Nov 09,OS 10.5,Powerbook g4

Powerbook G4 will not boot past the grey screen with spinning wheel after latest security update from Apple.
In safe mode: kdcmond could not launch is reported.
I DO NOT HAVE EASY ACCESS TO INSTALLATION DISKS.
Please post suggestions that are viable using rm or vi in safe mode.
It will take the IT department weeks to get around to fixing this so I am hoping for usable responses in the short term.
Powerbook G4 1GB os 10.5.7 to 8 Grey Screen/crash with exceptions after security update.
Took corrective actions using Disk Utility then Applejack with no success. Deleted Library/Prefernces/SystemConfiguration files: NetworkInterfaces.plist, com.apple.airport.preferences.plist, and preferences.plist to get them to regenerate. The exception is gone but now, kdcmond could not launch is reported due to no localhost name found.

No suggestions from anyone so I am giving up and returning the PC to IT. I will leave the thread open in case anyone comes up with any ideas for future reference.

Mail 2.0.5 CRASHES ON OPEN after Security Update 2005-009(Tiger Client)

I'm trying to figure out how to fix this.
I rebooted into a techtool pro e-drive and repaired permissions (as well as some other repairs to the drive, etc), but it still is crashing.
I created a new user and opened mail just fine there.
So... it is something in my account. Not sure exactly what to do next?

I'm having the same exact problem. (See Mail 2.0.5 crashes when I get new mail). I deleted my preferences & my junk mail settings, to no avail.
A remarkable number of other people are posting with similar problems, just in the past week or so alone, and as far as I can tell, no one has figured it out. There is definitely a bug here. I have a hunch that it may be related to a recent software update. I'm going to post this to the other threads in hopes of garnering some attention from Apple.
For posterity's sake, I am connecting to a Gmail account, a POP account, and a .Mac account.

Don't remove any screws to do an SMC reset:
Resetting the SMC on portables with a battery you should not remove on your own
Note: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

Or download and apply, or reapply, the 10.6.8 Combo update first, then apply the Security Update again.

Keyboard, keypad glitch after Security Update 2015-002

The overview is: keyboard problems developed shortly after Security Update-002 on Mavericks 10.9.5. I tried OS update to Yosemite; didn’t fix the problem. Reverted OS back to 10.9.5 using Time Machine for a backup date prior to the Sec Update; this fixed the problem.
Mac mini5,2, 16gbram, wired Apple Pro Keyboard (M7803, circa Mac Cube), Apple Wireless Keyboard, LMP Wireless Numeric Keypad, Apple Magic Mouse (A1296?) iPad 2
Within the past 2 days, Apple BT keyboard alpha keys stopped typing. During troubleshooting, I discovered that problems extended to BT keyboard, BT keypad, and wired spare USB extended keyboard. The BT keyboard pairs and works fine with my iPad. Here’s a list of the glitches:
Apple Wireless keyboard:
alpha keys NO INPUT
space key NO INPUT
Delete key works
Force-Quit sequence works
fn, cntrl, opt, Apple, arrow keys, shift all work
top row keys work
LMP Bluetooth keypad:
keypad: 1..4, 6..9 NO INPUT
keypad "5" registers a mouse click, NO INPUT
keypad "0" jumps to mouse cursor first press only, NO INPUT
=/*-+ and arrows work
Apple Pro USB extended keyboard:
num keys: 1..4, 6..9 NO INPUT
keypad "5" registers a mouse click, NO INPUT
keypad "0" jumps to mouse cursor first press only, NO INPUT
alpha keys and number row keys work
keypad =/*-+ and arrows work
Besides proving the wireless keyboard works on my iPad, I reset PRAM with no improvement. (I had no problems with my Bluetooth Magic Mouse.)
Next step was OS upgrade via Software Update to Yosemite. All above glitches remained.
Next, I reverted to Mavericks 10.9.5 using a Time Machine OS backup dated prior to 9Mar15, the date of Security Update 2015-002. After this, both keyboards and keypad resumed working. Seems clear that the Security Update is the culprit, no?
I reported the issue to Apple via Support Chat.
I would like to eventually upgrade back to the Security Update and Yosemite but not when it breaks my keyboard. Perhaps I could skip over the Sec. Update and go to Yosemite? Any suggestions?

Update:
The day after I reverted to 10.9 to repair keyboard glitches caused by Security Update 2015-002 (and persistent in Yosemite), Apple released Security Update 2015-004. Such a quick succession of -004 on top of both -002 and -003 was the hint to me that -004 contained fixes to the glitches.
I crossed my fingers and jumped back on the install-wagon. Yosemite 10.3 completed its second installation and my keyboards/keypads remain functional!

This is boot camp problem, because in other normal notebooks (e.g. SONY VAIO, Lenovo with Windows 7) the gadgets are working normally.

Have you reinstalled the latest Boot Camp Windows 7 drivers, just in case Microsoft overwrote some of them during the Windows 7 security update?

Is it possible to downgrade to mountain lion with the help of a time machine backup after having updated to Mavericks?

Is it possible to downgrade to mountain lion with the help of a time machine backup after having updated to Mavericks?

Just to be clear, if by downgrade you mean uninstall, then the answer is technically, no.
You can't uninstall an OS. You can erase and re-install the old OS, but if you don't have a prior backup of your data, you'll lose it during the erase procedure.

I can't seem to find any other posts about this problem.
I have three external hard rives connect by a USB hub to my iMac.
Problem is that if I turn on the hard drive(s) AFTER start up I get a message that the drive either was not recognized by the OS or that it was ejected unexpectedly.
I get the same issue but not all the time if I turn them on before I boot the iMac.
I used the disk drive utility to "repair" the drives but they always come back as "probably ok".
If I restart the iMac with the drives connected (on), it seems to work but not all the time.
A bit annoying as I am wondering if the drives are OK or not.
I don't always need the drives as they are for backing up images from my camera using Apreture.
This all began after i did the latest security update.
is the update to blame?
mahalo.

Yes, you can still use those instructions to reset the PRAM.
You said that you booted to your install disk and that your primary drive did not show up at the Select a Destination screen? That usually means that the computer is either not recognizing your partition, or it's not recognizing the hard drive itself.
Start with this article and follow all the steps even if you already tried them. I suspect that you'll get to step 4 and you'll end up having to call Applecare. If you haven't done those steps, they're most likely going to make you do them anyway, so you might as well get them done before the call.
