IMac won't reboot after recent wifi update

27 inch iMac running Lion OSX. Installed the recent wifi update that popped up in software update and now the iMac hangs on the gray boot screen. Ideas?

Try a safe boot. Hold the Shift key down between the start up tone and the Apple logo/pinwheel.
If successful, Go to System Preferences > Startup Disk > Select your MacIntosh HD and restart.

27" iMac i7 won't startup after recent security update

My iMac does not boot properly since I installed the recent security update. All I get is the circle slash symbol. Anyone have a solution?

Hi Carlos
Slip in the OS X DVD that came with your iMac, startup your iMac on the DVD, then open Disk Utility and Repair your Macintosh HD startup volume.

IMac won't boot after OSX Intel update crash - Newbie needs help please!

Hi,
at the weekend I updated OSX on my IMac 17 with an Intel update. An error message said that the update could not be installed and that the update was sent to the trash - a restart was requested. Since that shutdown my Mac chimes and gets stuck at the white load screen (hard drive is quiet).
I've tried the following:
Holding Shift key upon boot to initiate Safe Mode - No Joy!
Apple+S to run disk utlity/console - cannot initiate to cmd prompt!
Just as a little background - I'm a recent Apple convert and typical Windows defector. I've seen the light after many years in M**soft environments (I even trained to MCSE) but my Mac OS knowledge is considerably lacking. Let's be honest - so far I haven't had any problems.
Any gentle help would be most appreciated folks - I'm not sure where to start and I want my baby back!
Many thanks.

Same here. I have an iMac 20". It has been upgraded to Leopard and running fine since I purchased it 2 weeks ago. I downloaded the latest OS/X update (100+MB in size) but the installation failed. The system requested a reboot but it has not been able to ever since. It simply keeps beeping with a white screen. I put the Leopard DVD in, held the "C" key, but nothing works. Now I have a system that won't work. From now on, I will shy away from getting the latest update .... I am planning to take it to the apple store

IMac won't restart after latest Safari update.

I just downloaded the latest Safari update (5.1.2) on my iMac (27", i7, latest Snow leopard). The download (via software update) and install went smooth but when asked to restart, it hangs up at the gray screen...after the blue screen/start up chime, but before the apple logo appears. I tried shutting down and rebooting but it keeps hanging at the same place.
Thank you in advance for any successful solutions!
Kind regards,
Mark

Hi all,
Thank you for the replies...
I did manage to solve the problem right away by following the instructions offered by Apple: Remove all USB cables, then do a hard reboot. Then to isolate the cable causing the problem, plug in one at a time and reboot until the problem happens again. In my case, the issue was caused by a Flip Camera that was plugged into a USB hub.
I hope this helps those with a similar problem.
Regards,
Mark

IMac Won't restart after Wi-Fi update 1.0

I installed the Feb. 24 Wi-Fi Update 1.0 and got the prompt to restart now, which I did. Now my iMAc will not restart. It hangs on the gray screen with the Apple logo. Any help?
Thanks!

Try restarting in Safe Mode , then navigate to System Preferences - Startup Disk and make sure the internal drive is highlighted. When it's highlighted then restart using the restart command in the preference and let the machine re-start normally.
If that does not help then attempt restarting, when you hear the startup tone hold down the Option key and choose the Recovery partition and then choose Disk Utility. While in DU Repair Disk Permissions (do it 2x to be safe) and while you are in DU it won't hurt to run Repair Disk as well. After you have completed both quit DU then restart normally to test.

13.3 Macbook Pro Retina Keeps rebooting after recent iTune updates

This morning after I installed the new iTune updates (11.2.?), the macbook pro just flashed with some color stripes and then screen went black. I need to long hold reboot key to turn it off and turn it back on.
My iPhone was connecting with the Macbook during the update. I am not sure if this is connected to the issue. I unplugged iPhone and rebooted the Macbook. But right after I log in, the color stripe things came again and the macbook went dead. Now it is stuck in this status. I think I need to bring it to the apple store and have the "genius" guys fix it
updates: I waited for a while and reboot it. Now it seems working...

MACBOOK PRO / WON'T REBOOT / AFTER AUTOMATIC MAC UPDATE 06.FEB.2013

I am using Macbook Pro Mid 2010 with OS X Mountain Lion (10.8.2)
JUST RECEIVED A NOTIFICATION THAT APP STORE DID SOME UPDATE SO MAC NEEDS TO RESTART.
I CLICKED "YES".
NEXT THING I KNOW IS THAT IT IS UPDATING/INSTALLING, AND IT ATTEMPTS TO REBOOT. BUT IT DOESN'T.
ACTUALLY IT SHOWS THE USUAL START UP WHITE/OFF-WHITE COLOR SCREEN WITH THE APPLE LOGO IN THE MIDDLE, AND THERE IS A "DOWNLOAD/INSTALL HORIZONTAL BAR". IT "SHADES/DONE" AROUND 20% AND THEN THE MAC GOES OFF. BLACK SCREEN. SWITCHES OFF.
I TRIED SEVERAL TIMES. BUT RESULT IS BAD. NO LUCK.
I HAVE NO IDEA WHAT WAS THIS UPDATE. I WAS TIRED SO I DIDN'T PAY ANY ATTENTION.
PLEASE HELP.
P.S.
I HAVE SOME IMPORTANT DOC,S AND DIDN'T BACKUP (TIME-MACHINE) FROM LAST 25 DAYS

Gray progress bar appears under Apple logo during startup
If you want to preserve the data on the boot drive, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data, you can skip this step.
There are several ways to back up a Mac that is unable to fully boot. You need an external hard drive to hold the backup data.
1. Boot into Recovery (command-R at startup) or from a local Time Machine backup volume (option key at startup.) Launch Disk Utility and follow the instructions in the support article linked below, under “Instructions for backing up to an external hard disk via Disk Utility.”
How to back up and restore your files
2. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire or Thunderbolt cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
How to use and troubleshoot FireWire target disk mode
3. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.

IMac won't restart after latest security update

I have a late 2007 20" iMac with OS 10.10.2. While we were away last week I asked my son-ln-law to send me a photo off my iMac. He started the iMac and sent the file no problem. While he was on there he asked if he should run the security update while he checked the house so I said sure why not. He ran the update and came back in a few minutes and mac was off. He tried to restart it but it won't continue. It starts, the chime sounds, the Apple logo appears, it goes about 1/3 the way through the progress bar then sits there about 2 minutes and then shuts down. Trying to help with good intentions he found my Snow Leopard disk and inserted it thinking he might be able to use Disk Utility to eject the disk but since the disk is mounted an error message says the disk cannot be ejected. Not knowing what to do he just held the power button and it turned off.
Now that I'm back home I can't eject the SL disc and not sure what to do next. I've tried everything Kappy suggested here but nothing works. Unknown to my son-in-law I do have a Yosemite USB bootable drive but how do I run it with the SL disc in the DVD drive? I'm assuming I can restore from a time machine back up but with the SL disk in there does that cause a problem? I can see the Yosemite USB disk along with the SL disk in Disk Utility but not sure what to do if anything at this point. Suggestions?

Well I managed to get the Snow Leopard disk out and restarted the mac using OS X Recovery. I've selected the option to reinstall OS X. I'm at a screen that is asking me to 'Select the disk where you want to install OS X'. I'm presented two options one labeled 'EFI' and the other 'Recovery HD'. I chose the later but it's been sitting on a spinning beach ball for 30 minutes now so I can't select 'Install' to proceed. Any idea what has happened to my mac? A hard drive failure I assume or something else?

Mac mini server won't reboot after Installing security update 2010-003

This has already been posted and remaines "unanswered".
After updating to Snow Leopard Server 10.6.3 and attempting to reboot, the mac mini (HDMI) hangs on the gray apple logo with progress spinning. It takes me several times to force the mac mini to power down and try again, before it finally loads the login screen.
any suggestions?

Odd.
So it's hanging while starting services, it looks like, the firewall in particular, have you tried a safe boot?
If not, hold down the shift key right after you hear the power-on chime, keep holding it till you see a spinning gear.
This boots up without extra kernel extensions and fonts, clears font caches, and runs a disk verify and a repair if needed. If you still can't boot reliably in safe mode, you may need to run an archive/install.

IMac won't reboot after system restore from Time Machine

I just installed a wacom intuos pro tablet on my imac running snow leopard. The system clock reset to 1st Jan2000 and system prefenerces were no longer accesible. I performed a system restore from my time machine but now can't reboot. The restore completed succesfully (or so the it told me). When i restarted the imac i got the usual 'bing' followed by grey screen and spinning wheel swiftly followed by a light blue screen with the cursor in the top left hand corner.
There is sat for an hour befoe I switched off and tried again......same result.
The installation disc is still in the optical drive.
Any advice please on how to remidy this?
Thanks

I have/had a similiar problem. What I did was reset the SMC and PRAM. You can also do a safe boot. For the PRAM, I had to do three times, and my computer finally booted up. Afterwards I verified my disk and repaired my permissions. So far so good. I guessing that Spotlight needed to re-index the system.

Bluetooth mouse won't pair after recent os updates

Hi there,
Since I installed the two updates for snow leopard yesterday my bluetooth mouse will not pair.
I go to setup bluetooth device & when i press the button to make it discoverable it appears right
away so I click contnue & after a short while get the error message 'The pairing attempt was
unsuccessful. This configuration of Mac OSX & bluetooth software could be invalid or unsupported'.
On the initial discovery screen the messages 'searching for devices - one found' then 'updating 1
device name' appear. Have just tried pairing it on another windows system & it works fine!
Any advice appreciated.

If using a 3rd party mouse, check with its manufacturer to determine if they have compatible drivers.
If using Apple's mouse, post in the Mouse Bluetooth forum area.

4s won't reboot after ios7 update. I have restored 4 times. Every time it gets stuck on Apple icon with update bar at 10%

4s won't reboot after ios7 update. I have restored 4 times. Every time it gets stuck on Apple icon with update bar at 10%
HELP!

That's one of the weird things.. it recognizes it maybe 10% of the time. And usually, only after I do the two-button reset. Problem is.. since it won't charge above 2%, anytime I try to do a restore or anything like that using iTunes, my device shuts off and I lose whatever progress I'd made.
So, an update... after reading through a bunch of similar complaints (there are literally 1000's of them so there's NO WAY this isn't somehow ios7 related, thanks a lot APPLE ) I decided to try a restore in recovery mode. After 3 hours and several disconnections... I ended up having to just set it up as a new iPad, as the restore did nothing. Weirdly though... as I was doing the restore in recovery mode.. I noticed I'd gotten up to a 10% charge.. higher than it's been since September, so after setting it up as a new device, I turned it off and plugged it in using the wall charger. 2 hours later and I was up to 38%. Still not great, as my iPad, before ios7 could've fully charged twice in the amount of time it took for me to now get 28% more of a charge. And that's with a fully cleaned out device.. so that really ***** and I'm now more confused than ever.
But I'm gonna leave it overnight charging and see what I come up with tomorrow. Sadly, when I paid $600 for it in February, I never expected to have to play "wait and see" with it...

Programs won't launch & finder crashing after recent software updates

Finder and most programs won't launch after a software update. I was able to run Cocktail and repair permissions. I've restarted a few times, and ran disk utility from the start up disk to no avail.
Any suggestions?

Coldfusion 64 bit windows installer stops working after recent microsoft update

Coldfusion 64 bit windows installation stops working after recent microsoft updates and how I worked around it.
My question is at the end.
Trying to deploy coldfusion 9 enterprise 64 bit trial version onto a Windows 2003 64 bit datacenter OS with all OS updates from MS (as of 4-7-2011).
Steps taken (remember, this is all 64 bit):
1. Installed the base OS which was slipstreamed with SP2.
2. Checked w/ microsoft and installed 63 OS updates.
3. Launch the CF9 trial exe.
4. As soon as the first screen finishes (the one that looks like it is extracting files) then the second screen pops up (the one that simply says CF Adobe Coldfusion 9) and the progress bar quickly moves 95% to the right and the install application quits. No error, no nothing. No log file either.
5. After a moment of incredulous silence (and retrying/rebooting, etc), I started to google it. I found nothing. However, I did find a post (thanks dspent!) that was helpful in that it told how he was able to get at a log file of sorts, by pre-extracting the coldfusion_9_WWE_win64.exe file and launching the adobe_cf.exe by hand. (Dspent's install snafu was different than mine, but his post was very valuable and got me started in the right direction.)
6. Got a copy of rarunzipper and extracted the coldfusion_9_WWE_win64.exe file.
7. From the windows directory created by step 6, I launched adobe_cf.exe.
8. Same thing (the install application quits. No error, no nothing. No log file either.).
9. I examine the hs_err_pidxxxx.log file (where the xxxx is a number).
10. I see inside that file an ominous message: "A fatal error has been detected by the Java Runtime" then "Problematic frame ntdll.dll" and then "The crash happened outside the Java Virtual Machine in native code".
11. OK, so now I am thinking ntdll.dll !! Native code !! It is like Java is telling me that for some reason it can't dance with the OS.
12. On a hunch, I decided to test a CF install again on a server with just the base install of W3K3 64 SP2 (ie: skipping step 2 above this time).
13. Bingo! That install works.
14. Therefore, one of the 63 patches I had downloaded from MS had triggered a problem with the CF installer.
15. Back on the first server (the one with the MS security patches installed and the one that CF won't install on). In the CF file adobe_cf.lax (one of the files extracted in step 6) there is a line that mentions where the install gets it's java. Find that file, and check java version installer is using. It is using 1.6.0_14-b08.
16. Off to the Java website, and there is a newer version of java (1.6.0_24-b07). Downloaded and installed it.
17. Modify a line in adobe_cf.lax :
   before
     lax.nl.current.vm=resource\\jre\\bin\\java.exe
   after
     lax.nl.current.vm=C:\\program files\\java\\jre6\\bin\\java.exe
(that assumes that you let step 16 install to the default location)
Save the file.
18. Run the install ... ** IT WORKS ** !
Obviously, the built in java provided with the CF installer is no longer compatible with some change introduced by some recent MS update on the W2K3 64b SP2 platform.
And now the interesting part. Although I forced the installer to used the new java, it did not incorporate it into the cf build (ie: in jvm.config, you still see c:/coldfusion9/runtime/jre AND the version of java.exe that is in that directory is the original version, not the newer version I forced the installer to use).
On the surface, CF seems to run OK, but I have not done any application testing yet.
And finally my
** QUESTION **
Would it be appropriate to simply point the java.home var to the new java directory? I see that the directory structures and files are not exactly the same (close though) so I certainly don't want to break things by doing this, but instinct tells me that if the installer broke using the older version, then something else is gonna break down the road if I don't use the new version. On the other hand, the differences in the directories and files is enough that it makes me very nervous, with my limitied java skill set, to make this decision.
Thanks in advance!!
Byron

Hi Byron,
Wow great post no doubt much of the information will be useful for those on Win03 SP2 +. Have to say not come across similar problem on Win08 r2 SP1 +.
So to your question. Adobe security bulletin (http://kb2.adobe.com/cps/894/cpsid_89440.html) recommends running CF8 and CF9 with JVM 1.6.0_24. The bulletin does not say how to do that. I take you installed JDK and not just JRE 1.6.0_24? Post install of JDK follow these steps:
Stop CF - SERVICES.msc stop "ColdFusion 9 Application Server".
Take a copy of CF\runtime\bin\jvm.config - so you got a backup.
Edit CF\runtime\bin\jvm.config find line "java.home=" and comment it out eg:
#java.home=C:/ColdFusion9/runtime/jre
Add new line like so and save jvm.config:
java.home=C:/Program Files/Java/jdk1.6.0_24/jre
Note there the slashes and the location of the JRE (runtime) - you need to point to the one in JDK because the other JRE in C:\Program Files\Java\jre6 will be missing a DLL.
Start CF via SERVICES.msc.
HTH, Carl.
