Macbook not re-booting after installing the upgrades

hi,
Yesterday i did the latest upgrade on my macbook. i was then prompted to re-boot which i did. but now after the reboot all it does is that shows me my background screen for a second and fades back to the blue screen non-stop. i counted 10 repeats of that before i manually turned it off. any ideas?

In the future I suggest that instead of relying on Software Update to do the work you go to Apple Downloads site and manually download and run the updater required. Also If it's a system update repair disk permissions before and after. Some think it's overkill but better safe than sorry.
Try booting into the Safe Mode which automatically does a file system check and repair. It may take a while for the boot to finish as the file system check and repair will take some time.

MacBook won't boot after installing update 10.9.2

Hi there,
After successfully installing the 10.9.2 update on my MacBook Pro, I was able to boot to the updated system once. Then, suddently my macBook crashed and I was unable to boot again.
I managed to find a way to backup my files using the recovery mode and the Disk utility, however this wasn't straightforward to me since I was using FileVault..
Does anybody else have a similar experience with the 10.9.2 update?

The login screen appears as usual, and I am able to put username/password. Then, it fails to login and it returns the user to the login screen without mouse or keyboard working.
I booted using Command Button + S (single-user mode) and I see the error
"error loading mach kernel 0xe"
At least, I am able to boot in recovery mode to backup my disk :-)

My adobe Flash wont load after installing the upgrade to firefox 6..how can i get it to work?

i play the facebook games and i need to have adobe flash for it to work and when i upgraded the firefox to 6 the adobe doesnt download..i ve tried it many times and it wont download..

Symantec need to update their Firefox add-ons so that they are compatible with Firefox 4. They have indicated that for Norton 360 they plan to release an update to Norton 360 to support Firefox 4 in early May - http://us.norton.com/support/kb/web_view.jsp?wv_type=public_web&docurl=20100720113635EN&ln=en_US
I do not know about the time scale for updates for other Norton products. Pending the update by Symantec, if you want to use the Norton add-ons you will need to downgrade to Firefox 3.6.
To downgrade to Firefox 3.6 first uninstall Firefox 4, but do not select the option to "Remove my Firefox personal data". If you select that option it will delete your bookmarks, passwords and other user data.
You can then install the latest version of Firefox 3.6 available from http://www.mozilla.com/en-US/firefox/all-older.html - it will automatically use your current bookmarks, passwords etc.
To avoid possible problems with downgrading, I recommend going to your profile folder and deleting the following files if they exist - extensions.cache, extensions.rdf, extensions.ini, extensions.sqlite and localstore.rdf. Deleting these files will force Firefox to rebuild the list of installed extensions, checking their compatibility, and reset toolbar customizations.
For details of how to find your profile folder see https://support.mozilla.com/kb/Profiles

My Mac Pro won't boot after installing the latest update

Im running the latest OSX on my mac and recenty did a small updated that i believe contain a few security thing and bug fixs but when restarting the machine after the update it would not boot again after the apple logo has appeard apple script is displayed on the screen contain what i think is boot script failing to run. I have been able to boot the system in safe mode. does anyone have and solution for this as i realy don't want to reinstall the OS
Thanks

The most common cause for "Won't boot after software Update" is Directory Damage that existed before the Update, but was made worse by adding files during the Update.
The most common cure for that Directory Damage problem is to boot in Safe Mode, which takes five minutes to repair the disk, then comes up demanding your username and password, even if you normally auto-login.
Rarely, third-party add-ons are made obsolete by an update. In this case, booting in Safe Mode (with few Apple extensions and NO third-party extensions loaded) works fine, even if normal mode does not work.
Have you tried normal mode again after your Safe Boot?

Macbook won't boot after installing Security Update 2008-007 (Intel)

I installed security update 2008-007 (intel) on my MacBook last night using Software Update, but now my machine won't boot at all. All I get is the gray start-up screen with the dark gray apple, but there's no spinning progress bar or anything. After 5 minutes or so, the machine auto-restarts, but again hangs on the gray start-up screen. It does this over and over again until I shut it off. I tried to boot into safe mode by holding down shift right after the chime, but it still wouldn't boot (again, not even a spinning progress bar). Can anyone please help me? I really don't want to lose my photos/movies, etc. I'll backup everything promptly if I can just get it to boot. Thanks.

Hi jared-lee, and again, a warm welcome to the forums!
First for safety, "Try Disk Utility
1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk."

This may or may not fix the problem, but may.

GNOME3 is not working well after install the nvidia driver

I changed my graphic device from intel (integrated in i5 sandy bridge) to nvidia (GTX550 Ti).
When I reboot my PC, an error about GNOME failed something was showned.
I ignored it and installed nvidia package using pacman.
After that, I installed new nvidia driver but GNOME is not working properly.
Terminals which I can see when type ctrl + alt + function key are not working either.
This is part of my desktop screenshot.

I have no big issues with gnome3 and nvidia, in case you haven't, make sure your xorg.conf is correct or you can let nvidia make it for you, just backup/delete your current one (if any) https://wiki.archlinux.org/index.php/NV … figuration

Windows 8.1 Pro not booting after install of Hyper V - ASUS z87 + intel 4670K

Hi,
I am running windows 8.1 pro on a intel 4670K 4th Gen Haswell CPU and ASUS z87 plus motherboard. 16gb of kingston hyperx ddr1600 memory.
I have enabled virtualisation technology in the bios. CPU has SLAT.... or Extended Page Table, as intel likes to refer to it.
When I install HyperV platform and management tools the computer configures and reboots
AFter reboot it brings up the blue window image and spinning circle of dots for a while then reboots. It does the same thing again and then reboots and goings into repair mode and asks me to do a system restore. It then restores to before they HyperV install.
I've tried turning off xHCI mode (i.e USB 3.0) in the bios as this seemed to be a known issue with some gigabyte boards. This did not rectify the issue
Updated to latest asus mainboard bios 1405. Same issue still occurs upon install of hyper V.
Automatic repair does not work and I have to restore from system restore point.
I performed a clean boot after installing the feature and it still couldnt boot to windows.. it just sits at windows logo and then restarts a few times and then launches the startup repair. Once the startup repair begins, the only way I can get into windows
is restoring to a system restore point from before the hyperv feature install.

I logged a job with asus support and their response was:
"Clear CMOS and ensure virtualisation technology is turned on in BIOS. If it still doesn't work, seek assistance from Microsoft"
Previously asked this question but took a while to get back to update with the logs and it was listed as Answered.
This issue is still existing and I'd appreciating any assistance.

After installing Facebook upgrade, login screen wo...

After my initial mystery problem on accessing Facebook on my new Nokia 6700 Slide (as mentioned elsewhere on this forum), I was eventually able to access it with no problems, had saved my login info, so hitting the Facebook button was all I needed..
However, last night, I was going to do a quick FB check, and hit the button as usual. I found that I was now logged out.
As I started entering my login info, a link popped up, saying that a Facebook upgrade was available.
I thought, I might as well upgrade there and then, to keep my phone applications up to date.
Mistake
Downloading & installation went fine, I got the notification saying that installation was complete.. But when I hit the FB button to enter my login info, the login screen would not stay on the screen at all! As I hit the button, the login screen appears for maybe less than one second, but there seems to be no way of making it stay on screen, so that I could actually enter my info.
I checked whether there was an alternate way of accessing FB, rather than using the button I have on my quick menu bar.. I found that, after installing the upgrade, I now had a FB link in Menu > Applications > Installations (I know it wasn't there before as the only default installation was G.I.JOE, the game, and I'd since added Backgammon and nothing else). I tried logging in that way, but the same thing happens - login screen won't stay open.
I wonder, is this happening to anyone else, and would anyone have an idea on how to fix it? (Is there a way to uninstall the upgrade that messed things up? Is the upgrade at fault, and is there a new upgrade on the way soonish?)

O...k.... As with the previous FB-related problem, this one seems to have sorted itself with time as well!
Maybe next time, I'll give it a day before posting yet another topic here

Has anyone's screen go blank and not boot up after installing the new yosemite OS

has anyone's screen go blank and not boot up after installing the new yosemite OS

Hi Mofimac,
Thanks for visiting Apple Support Communities.
If your Mac is only starting up to a blank gray or white screen after updating OS X, you can find some useful troubleshooting steps in this article:
Mac OS X: Gray screen appears during startup
I recommend going through these first three sections first:
Disconnect, test peripheral devices and network cables
Perform a Safe Boot
Reset the NVRAM / PRAM
Best Regards,

I just installed MacOS X Yosemite on my MacBook Air 2011. After installing Yosemite I installed the Photoshop Elements 12.1 upgrade, but now when I open the program and try to use the tools, the program freezes. How do I fix this problem?

If you use a trackpad and don't want to switch to a mouse, you can uninstall and reinstall all day long and will still have problems, but if you really want to try it, you can download PSE 12 here:

Actually it sometimes gets a little further, the display will dim and the pointer will appear and then whoop it will turn off. if i do a verbose start up, it will finish all the steps, the white screen will appear and dim and then it will turn off.

Will not start even in safe boot after installing latest camera update

MacBook Pro will not start even in safe boot after installing latest camera update.
I started my machine and did a software update. Only the camera update needed. So installed and when required I pressed restart. It restarted and did install. Then restarted again. I expected to get to the login screen and it turned itself off. Tried three more times. Each time shutting off. I unplugged everything, and pressed start waiting for log in window. No it shutdown before the log in window. I then tried safe mode and that did not work either on three more occasions.

I have managed to resolve some issues. I can now restart the machine via a CD boot. If I do cmd C into something like tech tool pro, then restart from that disks menu it restarts every time.
If I try a safe start it shuts down. If I try a normal start it shuts down. I have managed to repair permissions and that cleared up some start up permissions but with no improvement to the boot problem. The only way to load is via the cmd-C boot option. Any other ideas?

Macbook pro won't boot after installing update 10.9.3

macbook pro won't boot after installing update 10.9.3

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.
