Computer is not booting after installing mavericks

i have a late 2009 imac and downloaded mavericks. It installed and the computer rebooted. Now it is in some weird and awful loop. The computer begins to boot and then it gives me the“Your computer restarted because of a problem” message and then goes to to the gray apple screen. It will sit there for about 2 minutes and then the screen turns half black with a bunch of code about kernels. No clue on how to fix it. I've removed all attached peripherals.

when the computer starts hold shift before the chime. if it goes to your log in screen great. log in, then go into your system preferences, users and groups, login items. remove any 3rd party applications. Then go into finder>under the go menu select computer, go into macintosh HD then into library and remove all items from these 3 folders. LauchAgents, LaunchDeamons, and Startupitems. you have an incompatable file running on your computer, if that does not work call Apple care you have phone support since you upgraded to mavericks.

Hmmmm... would appear that you need to be actually logged in to enable the additional menu features.
Have you tried deletting the plists for MAS?
This page might help you out...

ITunes not working after installing Mavericks

I cannot open i.tunes after installing Mavericks. I cannot unistalled it either (to reinstall it) since a window appears saying it cannot be dropped or changed in any way. Thank you for your help.

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve your problem.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to gather information about the state of your computer. That information goes nowhere unless you choose to share it on this page. However, you should be cautious about running any kind of program (not just a shell script) at the request of a stranger on a public message board. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them.
Here's a summary of what you need to do: Copy a line of text from this web page into the window of another application. Wait for the script to run. It usually takes a couple of minutes. Then paste the results, which will have been copied automatically, back into a reply on this page. The sequence is: copy, paste, wait, paste again. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in your browser, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign ($) or a percent sign (%). If you get the percent sign, enter
exec sh
in the window and press return. You should then get a new line ending in a dollar sign.
Click anywhere in the Terminal window and paste (command-V). The text you pasted should vanish immediately. If it doesn't, press the return key.
If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know your password, or if you prefer not to enter it, just press return three times at the password prompt.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that takes administrator privileges.
The test may take up to a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line "[Process completed]" to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report your results. No harm will be done.
8. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If it happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

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.
Please see the following logs which may have further information:

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.

External Hard Drive not working after installing mavericks

After installing mavericks, I hooked up my external hard drive,
and it would not show up on the computer. Tried checking if
it showed in utilities, also a no show.
Should I uninstall the ntfs software which is a few years
old and instal a newer version?
Looking for a solution which doesn't involve reformatting my nearly full
1TB EHD, please :)

I think I have version 10.8.6 of mavericks, not 10.9.

Apps do not open after installing mavericks

After installing mavericks i tried to reinstall a few apps i bought five months ago. I can load them over the appstore, but when i open them, they instantly close again and it says:
"name of the app" is damaged and can not be opened. Delete "name of the app" and download it again from the App Store.
it did this a many times, but it´s always the same. and there are only a few apps that i can´t open, others are working well. A few weeks ago those apps were also working fine.
If somebody knows help...

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, or by corruption of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in 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, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of steps 1 and 2.

Dock not working after installing maverick

After installing Maverick on my Macbook Pro, my dock which is positioned at the bottom now freezes. Prior to update, just placing my cursor at bottom of screen would bring up the dock. Now, it either doesn't come up or I have to place my cursor down there several times before it finally pops up. Anyone else experiencing this issue?

Revealing the Dock while in a full-screen app requires not only moving the cursor to the bottom of the screen, but keeping your finger on it or moving the cursor along the bottom edge (or other "tricks") to reveal the Dock.
SUPER ANNOYING TO ME
Many users may like that way of operation, perhaps a great majority. But hundreds of thousands may find it annoying to have this cognitive pause imposed and would rather have the dock appear accidently once in a while when moving the cursor close to the bottom area of the display.
This worked before Mavericks:
Setting the Dock autohide delay to zero (in Terminal, with write defaults...) removed this annoyance. As soon as your cursor's at the bottom of the screen, the Dock's there.
In Mavericks: Nothing to do! (so far)
APPLE: "You" make WRONG design decisions, "you" make professional users spend dozens of hours investigating how to tweak basic features behind the scenes. And THEN, "you" quietly invalidate those changes. Please, the best design decision that "you" could make is to give the user more choice. Please, give us a section in Preferences where these things may be changed. The religious dumbing down of the interface in favour of supposedly clean esthetics is plain WRONG.
It is also quite unacceptable that APPLE does read these pages but never responds.

Hi,
You don’t install VS2010 on the client PC, then where did the Form Invoice not work? When you run it from another version of VS? Or when you run the application with application.exe?
Based on your description, one form works well, another form does not. I assume that two forms are in two different projects, then please check the .Net Framework used by the two projects. If they are different, you can use the
one used by the Form contact for Form Invoice.
Because this issue is a project issue, I recommend you to consult it on some application forum such as Windows Forms General forum for better support.
VS General Question forum mainly discusses
the usage of Visual Studio IDE such as
WPF & SL designer, Visual Studio Guidance Automation Toolkit, Developer Documentation and Help
System and Visual Studio Editor.

Seagate 2TB HD not working after installing Mavericks

Aproximity 3 weeks after installing Mavericks my 2TB Seagate HD could not be detected on my desktop
I've read several articles stating other user's have the same problem, some articles mentioned that the HD
is damaged and should be re-formatted, others need there data now and there unable to retrieve it.
This is what I ended up doing since re-formatting my HD is out of the question since a fix for this issue
will eventually come. I simply connected my HD to my Apple Airport Extreme Modem and it connected
perfectly over my home network. I was able to retrieve data without any problems, sure beats the other
options I've read. DO NOT RE-FORMAT YOUR DRIVE!!!

Grafton, Ohio

This seemed to be a temporary symptom. Its working now. I have 2 thunderbolt adapter, so I plug in the 2.5inch adapter and it worked. Afterwhich, I eject the 2.5 inch adapter and tried the 3.5 GoFlex Desktop Thunderbolt adapter, and it worked. The above post on the Seagate thunderbolt drive was for the 3.5inch Desktop Thunderbolt adapter.

Mail not working after installing Mavericks

Mail stoped working after installing Mavericks!

Check this out. It worked for me and is related to a problem in Accounts.plist...
The problem was caused by dodgy entries in the accounts.plist file in my User Library folder. It appears that either when I upgraded to Mavericks this file gained hundreds (possibly thousands) of spurious entries, or maybe these entries were in there before but previously the OSX/Mail combination was more tolerant. When I removed these the problem with Mail disappeared. Here’s what I did….
1> Make the user Library folder visible - in Mavericks this is a lot easier than Lion/Mountain Lion. Simply open up your user directory in Finder, select menu View>Show View Options, and select “Show Library Folder”
2> Navigate through username>Library>Mail>V2>MailData and select the Accounts.plist file. If this file is multiple megabytes (mine was 40+mb) then this is likely the cause of your problem (once sorted mine ended up at 19k in size!)
3> To be safe, make a copy of this file (I placed the copy on my desktop).
4> Using your chosen text editor (I used Text Wrangler but I’m sure TextEdit would work just fine) open the Accounts.plist in the MailData folder (not your backup copy) and take a look. If it’s the same as me you will find hundreds and hundreds of entries for the same mailbox repeated in there. Mine was an old MSN mailbox that I never use any more (I’ve seen in other forums that other Hotmail type accounts also seem to be the culprits in this context). There will likely be two lots of repeated data, one in the XML “DeliveryAccounts” <array> section, and one lot in the “MailAccounts” <array> section.
5> Delete (keeping in mind the need to select the XML sections correctly from <dict> to </dict> completely) all those extra entries that you found, keeping the mail accounts you do need, in the XML and save the file.
6> Mail should open up nice and fast again and not eat your system
7> If this did not work, and causes problems because of over eager deleting in <5> you can replace your broken Accounts.plist file with your backup and try again.

Late 2008 Macbook Pro doesn't boot after installing Mavericks

I have a late 2008 Macbook Pro, dual core 2.53 GHZ, 4 GB Ram (2x2).
I've been tearing my hair out trying to get this computer to boot up. Many things have been tried here. So here's the history.
Before starting this, I was running 10.6.8 on this computer.
First time I tried to install Mavericks, the installation failed, and when the computer went to restart, it just went in a loop, never really booting up, just getting the to gray screen with the apple symbol, spinning the wheel, and then going black again, restarting, and repeat. So, I took it into the Apple Genius Bar, and they diagnosed a bad battery. I replaced the battery, and had them do a clean restore back to 10.6.8.
I got it home, and tried to do an install again. This time, I downloaded the installer, and put in on an external firewire drive, and attempted to do a clean install of Mavericks. I ended up with the same boot failure problem.
I went back to the apple genius bar, and even though the diagnotics said my harddrive was fine, they said in the troubleshooting list, that the harddrive with the first thing they suspected. So, I replaced the harddrive. I did the Mavericks install again from an external HD, and for a moment, everything was great. It booted up into Mavericks. But, after my first restart, the problem was boot failure was back.
After reading a few articles, I tried booting in Safe mode. That worked. I also ran disk repair on the HD and it looked great. Still, it won't boot up out of Safe mode.
After being very frustrated, I tried just installing snow leopard from the dvd, but the install keeps failing.
Not sure what to do next.

Micajah10,
rather than a hard drive problem, you might have a faulty internal SATA cable. Do you have an external disk enclosure, or a SATA-to-USB or SATA-to-FireWire adapter? If you can boot from your hard drive without problems when it’s external, but it remains problematic internally, then that could point to the internal SATA cable as the culprit.

Windows 8.1 Pro will not boot after installing iTunes 11.1.5.5

It's a little hard for me to accept that this is true, but the symptoms seem to be pointing the direction of the title of this thread. I have an all-in-one touch-screen Gateway computer that came with windows 7 (yeah, a win7 machine that came with touch, yeesh) and I put windows 8.1 pro 64-bit on it with a clean install (actually windows 8 was the clean install and then I did the free microsoft store upgrade to 8.1). It has 4GB of RAM and has a Pentium Dual Core cpu @ 2.2 Ghz. It was running fine with the previous version of iTunes, but as soon as I updated to iTunes 11.1.5.5 (and there may have been other apple things that updated too (ie quicktime of course), the computer prompted me for a reboot and froze during the reboot process (before it even shut down). Then it had trouble booting into windows. I ran startup repair to no avail and decided to do a sytem restore. My most recent restore point was from a few weeks back, before iTunes was even installed at all on the machine. I went back to that point and the machine worked fine again. Then I installed iTunes 11.1.5.5 and the same exact problem occurred - it froze while shutting down after the iTunes install and then would not boot into windows 8. I did another system restore and have not put iTunes back on. The system is working fine. I'm going to try to find out if there's a way to download older versions of iTunes, so that I can install it, but the bigger issue here is: Is this a legitimate bug/incompatibility with some hardware or software or driver that I have on this computer? I run a computer support business so I know my way around but I don't have time to troubleshoot this from scratch. Anyone else seeing this? Apple employees...a little help here? Any input?

let it sit for about 30 min and still got nothing
I then did a "hard shutdown(just pressed power button till it turned off the computer)"
That may not have been long enough. But a "hard shutdown" would definitely have been construed as a problem due to the update.
Asus apparently is a known problem case...
