Did a firmware update 2/29/12 and now my second monitor stopped working, turns on and is detected but goes black

I did a recommended mac os update on 2/29/12. It also performed a firmware update. When I restarted my external second monitor came on and then went black. The monitor is detected and if I change it's size it comes on couple of seconds and goes black again. Any idea what might be the problem? No problems experiecned before update.

Well THANKS Matt_G..... I opened in safe mode and all my previously opened tabs, from when it last worked, displayed properly. I then started Aurora normally and it failed again so took your advice about disabling Add-ons and now all is working properly again. Not sure which Add-on it was because I disabled almost a of them since they really did nothing for me. I might go back tomorrow and try to find the one that did me in. Think that when you update Aurora it checks for new versions of Add-ons and that could also have gotten me.
Thanks again,
Rodger

Just did a Firmware Update and can't receive or send mail

I just did a firmware update as recommended by Apple:
2008-04-13 18:30:24 -0400: Installed "Aluminum Keyboard Firmware Update" (1.0)
2008-04-13 18:30:32 -0400: Installed "iMac EFI Firmware Update" (1.3)
I had restarted my iMac and noticed that my Mail 3.2 will no longer connect to my mail servers and send or receive mail.
My internet connection is fine when using my browser. I closed and restarted "Mail" and this didn't help and even restarted my computer but that didn't help either.
Anyone else that just did this update have a similar issue? Anyone know of a fix? I don't think I can undo the Firmware update now, so what do I do?
Thanks

Try a reset: Simultaneously hold down the Home and On buttons until the device shuts down. Ignore the off slider if it appears. Once shut down is complete, if it doesn't restart on it own, turn the device back on using the On button. In some cases it also helps to double click the Home button and close all apps BEFORE doing the reset.
Delete and re-add the email accounts.

Firmware update 7.2.1 and now airport extreem won't work

I did the firmware update for 7.2.1 the other day and ever since the airport extreme base station keeps resetting itself over and over again then I unplug it for a few hours and plug it back in and its ok for a while then it does it again. When it is doing this I cannot connect to it with the airport utility and when I finaly get connected I try to put the firmware for 7.1.1 back and it just sits at 0% forever.
I'd realy apreciate some help with this. I have guests here and none of us can get to the internet and its getting frustrating as heck!

did you try to reset your base?
This is helpful in some cases.
You will find instructions here:
http://docs.info.apple.com/article.html?artnum=107451
Please be patient.
Attention: Resetting your base will erase all of it's settings!

My MacBook pro did a firmware update now will not accept my password

My Skype account was hacked so I changed the password for my computer too I did a firmware update the computer started up and went to a black screen asking for my password it does not accept the new or old passwords. I have tried resetting the password with the snow leopard install disc but it will not recognise it and ejects. Please help

Try image capture (in your applications folder) - or the finder - if neither of these see the card uyou need to try a USB card reader - once you get yoru photos off use the camera format command to erase and reformat the card
a best practice to is to never have any computer program (including iPhoto) delete the photos from the card but to import the photos and keep them and then after at least one successful backup cycle has completed and then reformat the card -- I use three very large (32 GB) cards in rotation so I do not reformat for typically a year or more giving me one more long term backup of my photos

Firefox did an automatic update to 6.01, and now my middle mouse button is not working in the browser. It doesn't close tabs, it doesn't open new tabs by middle clicking a link, it doesn't allow me to middle click to scroll the page...

[BUG FIXED, see "EDIT 2" at the end of my post]
I'm on Firefox 3.6.21, and I got this problem today after a Greasemonkey update (To version 0.9.10, apparently).
Disabling Greasemonkey solved the problem, and re-enabling it reproduced the problem (middle-clicking links to open in new tab did not work, merely highlighted the link).
I should also note that while Greasemonkey was enabled and the bug was affecting me, Ctrl+Click to open links in new tabs was also broken.
I hope this helps!
EDIT: It appears this is a known incompatibility/conflict bug between current versions of Greasemonkey and Tab Mix Plus. Read more here:
https://github.com/greasemonkey/greasemonkey/issues/1406
EDIT 2: GREASEMONKEY HAS NOW BEEN UPDATED with a workaround to fix the problem. Go to https://addons.mozilla.org/en-US/firefox/addon/greasemonkey/versions/ to install the update manually. It hasn't been reviewed by Mozilla yet, so it won't be an automatic update for another day or two. All credit to "cannonfodder" below for noticing this; please mark his post as helpful!

I did an auto-update on itunes today and now itunes is unresponsive..it gives this error "An application has made an attempt to load the C runtime library incorrectly. Please contact the application's support team for more information."

Wouldn't apple check before releasing new version, I see so many people with same issue..its such a waste of time for everyone now to fix it.
Is there any other way to fix before I try to un-install everything and re-install back?

Just did firm ware update on time capsule an now my airport express not connected do to air port utilities doesn't support base station ??

just did firm ware update on time capsule an now my airport express not connected do to air port utilities doesn't support base station ?

I have been experiencing some networking problems
Welcome to Apple's discussion groups.
I have the latest Time Capsule ("TC"), an old Airport Extreme Base Station ("AEBS") bought in 2007 and 2 Airport Expresses, one bought in 3 months ago ("AE-Alpha") and the other bought back in 2007 ("AE-Beta"). All of them have been updated with the latest firmware.
Based on those dates, the AirPort Extreme is probably flat (as opposed to dome-shaped), making it 802.11n-capable. The Newer AirPort Express is probably an 802.11n-capable model A1264, while the older one is probably a model A1084 or A1088.
I use {the TC's} DHCP function ... to avoid unauthorized use.
This a discussion for another thread, but that's not what DHCP is for.
The wireless setting for it is to participate as WDS Main, but after reading various posts, it seems WDS is a bad idea
With that older AirPort Express you're stuck with WDS unless you decide to replace it with a newer model.
The AEBS is currently setup as being a WDS Relay at the moment
Why a relay? That's only needed if there's another base station "beyond" it that is configured to depend on it.
Since the AEBS is connected to the TC via Ethernet, you should probably configure it as a "roaming network":
http://discussions.apple.com/thread.jspa?threadID=2273124
{The AE-Alpha} connects fine as WDS remote at the moment
I don't have any experience with mixed WDS and non-WDS networks, but since it's 802.11n-capable, you may be able to configure it to "extend" the network of the TC rather than as WDS. Look for a setting on the TC to "Allow this network to be extended".
Physical location:
AEBS in one end, TC and AE-Alpha in the middle while AE-Beta on the other end.
A device such as "AE-Beta" that's supposed to extend a network shouldn't be "at the end" but should be half way between the central base station and the clients that need an extended network.

Can't update due to message saying a prior update is still running and to reboot, but I have rebooted 4 or 5 times

Can't update due to message saying a prior update is still running and to reboot, but I have rebooted at least 4 or 5 times What do I need to remove to get the install to work?
I am stuck at FireFox 3.6.18 as no update actually installs, even when I am logged in as the admin.
i am running XP SP3
I have the update files for version 4, 6, 8, and 10. IF I can figure out the error - probably in the registry - which update should I start with

If there are problems with updating then best is to download the full version and uninstall the currently installed version and delete the Firefox program folder to remove any leftover files.
Download a fresh Firefox copy and save the file to the desktop.
*Firefox 10.0.x: http://www.mozilla.org/en-US/firefox/all.html
*Firefox 3.6.x: http://www.mozilla.org/en-US/firefox/all-older.html
Uninstall your current Firefox version, if possible.
*Do NOT remove personal data when you uninstall the current version or you lose your bookmarks and other data because all profile folders will be removed.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
*It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.

I was updating my macbook pro and it restarted but didn't boot up. It made it to the gray apple screen with a spinning wheel underneath it. What do I do?

This was happening to mine as well and I had to take it in a few times and they had to wipe it completely. If your computer is more that 5 years old, it may be that it is time for a new one. I suggest taking it in so they can diagnose it!

You switch keyboards by going to the " flag" menu at the top right of the screen.

Hey, thanks for replying. It is the user who needs to manually submit the page.
Basically our page has a hidden div with various text fields and combo boxes. When the user click on specific links on the page, this div is populated and made visible to the user in server side code.
What happens for all other browsers other than firefox 23 onwards (worked fine in 22) is that after the user clicks on the link, our server side code is executed via a HTTP post. The server then renders the hidden div and sends the additional HTML down to the browser via ASP.NET AJAX.
With Firefox 23, the additional HTML is not rendered on the first postback. Subsequent clicks of the same link execute the same server side code but the additional HTML is rendered on the browser without issue.
We've done a lot of debugging now and the issue is localised to a specific third party supplier's (Infragistics) control. I think Firefox 23 must have changed the way that the viewport or screen bounds are calculated or reflected back to this control as the issue seems to stop when we remove the control's MaintainPositionOnScroll attribute. It might be that the Firefox 23 DOM is not able to provide the screen dimensions accurately when the page is first rendered. I say this as the second postback renders the additional HTML fine.
The control in question is quite an old version so I don't think it's your issue to be honest.
Just so that this might be helpful to other developers using the Infragistics Window Dialog Control, setting MaintainPositionOnScroll to false solved this issue for us.

Mountain Lion 1.8.2 update made my dual monitor stop working on Mac Pro mid 2012

Just done Apple's update for Mac OS X Mountain Lion to 1.8.2 and after rebooting my dual monitor stopped working.
If I go on preferences -> Displays it shows me only one of my two monitors, even if I invert the connections the 2nd monitor doesn't shows up and there seems no way to enable it again.
Any suggestion?
P.S. I already tried to set from "Best for display" to "Scaled", but after rebooting Mountain Lion 1.8.2 reset it to "Best for display"

Ok,
did some extra test here, but first of all my configuration:
Mac Pro (Mid 2012) with ATI Radeon HD 5870 1GB.
2 LCD 24" Wide-screen (1st monitor Hyundai W240D and 2nd Monitor HP w2448hc), both LCD worked perfectly until reboot after installing OS X 1.8.2
After reboot only the 1st monitor wored fine, the 2nd not even listed, so tried to invert cable connections on the 2 miniports on the ATI video card, but nothing changed, still only the 1st monitor working.
Did a second test, disconnected the 1st monitor and connected ONLY the 2nd and now the second works fine.
Tried to connect 2nd monitor on a different miniport, and i still works fine.
Updated my MacBook Pro to 1.8.2 (it as an nVidia card) and connected my 2nd monitor to it and everything works fine, both the laptop LCD and my HP LCD are working fine.
So it looks like Apple screwed up the ATI driver on the latest 1.8.2, now only ONE miniport is active.
To all users with the same Mac Pro configuration: hold to update to Mountain Lion 1.8.2 until Apple fix this driver issue.
More info are on the Console output, so will have to contact Apple on-line support to signal this bug.

Can not connect the iTunes Store, since the last update 2 weeks ago, iOS 6.1.2 has stopped working, help me, please ....

can not connect the iTunes Store, since the last update 2 weeks ago, iOS 6.1.2 has stopped working, help me, please ....

Ok, I am having literally identical issues with Marathon Max.
I try to connect, and it says, "Itunes could not connect to the itunes store, Make sure your network connection is active and try again." I have contacted my ISP, and they ran a full check, and sayed I should be able to connect to pretty much all websites. I did the whole "ipconfig" thing and that was no help. I also tried the "msconfig" thing, and it sayed it did not recognize it as any kind of command, internal or external command or operable program or batch file. Whats strange is I can connect from another computer just fine, but when offered to upgrade itunes I declined for fear of the same thing happpening. I am tempted to just upgrade it and thus demonstrate that itunes has a flaw in their upgrade. I will save this computers diagnostics, and the other one's too, before and after the upgrade. I look forward to sending more feedback regarding this matter
