Prohibited sign on start up and error when trying to re-install os x maverick. Help?

So I get the prohibited sign on start up, and i tried using the command-option-p-r and os x utilities popped up. I checked if any of my disks needed repairing and all of them were fine. But whenever I try to re-install os x mavericks an error would come up saying that I need to restart the application.
Help anyone?

This is what I would try:
Since a 2008 MBP came with Leopard (10.5) and to install Lion (10.7) or later requires a Snow Leopard disk (10.6), I would use one of those disks. Again check the status of the HDD with Disk Utility>First Aid using the disk and install an OSX. You will then have to download the Snow Leopard combo update (10.6.8).
https://support.apple.com/kb/DL1399?locale=en_US
You will have to erase the disk so have your data backed up, Once you have established that you have a working OSX installed, then I would download Mavericks.
If you cannot install an OSX with the disks then there is a hardware problem and a trip to an Apple store genius bar will be the best option. The evaluation will be FREE.
Ciao.

I've started getting an error when trying to transfer purchased videos to iPhone.

I've started getting an error when trying to transfer purchased videos to my iPhone.
I get an error saying that selected videos will not play on the iPhone. They were purchased from iTunes and have been played on the phone previously.
So far I've only noticed it on SD/HD videos, but not all SD/HD videos. Not had an issue yet with the judt SD files.
Anyone else encountered this?

YAY!!! Saved it in my Mac's Firefox Bookmarks for easy future access!
Hope you are having a lovely afternoon today! I'm about ready to go bobo....I have an early meeting, and I don't want to oversleep! The nice part is that I work remotely, so I only have to wake up 15 minutes or so before the meeting.... I don't even use an alarm clock anymore (really, my iPhone alarm, which is much more pleasant), unless I have to get up at 6:30 or something....

"Cannot Start Video Chat" error when trying to do video conferences

Ahoy!
I've recently upgraded to a new still camera that unfortunately doesn't work with iChatUSBCam, so I invested in a nearly-new iSight to use with my PowerMac G4 instead. Although one-way video chat conferences work fine, I keep getting the error "Cannot Start Video Chat" whenever I try to do a video conference.
The full error message reads:
"*Cannot Start Video Chat*
Your computer is not capable of initiating a multiperson video chat.
Click Text Chat to invite the selected people to chat."
There are no error codes or any other text in this message. The available buttons are the purple ?, 'Text Chat' or 'Cancel'.
I have tried this on both my 1.25ghz PowerMac G4 and my 1.33ghz PowerBook G4, and my friends I am trying to chat with have tried to initiate the conference on their 2.16ghz Intel Core Duo MacBook and MacBook Pro, only to receive the same messages too.
When doing a one-way videochat, the + button to add more people to the conference is greyed out for all of us as well. We all display the video conference button (camera with the extra pages behind it) next to our names on our buddy lists though, so our computers all believe we're capable of it!
When clicking the ? button on the "Cannot Start Video Chat" dialogue, it brings me to the help page that tells me:
+"To join a multiperson video conference, you need any G5 computer, or a 1 GHz single processor G4, or a dual processor 800 MHz G4, and a broadband connection to the Internet.+
+To host a multiperson video conference, you need any G5 computer, or a 1 GHz dual processor G4. In addition, you need an Internet connection that supports a minimum download bandwidth of 384 Kbps, and a minimum upload bandwidth of 384 Kbps."+
Both of my machines are above 1ghz G4s, so according to this help file, it shouldn't prohibit me from at least joining a conference when I'm not the host, but both of my Intel-based friends get the same message when trying to host as well. We are all on respectable Broadband or Cable internet connections, so that shouldn't limit it!
Anyone got any ideas what the problem is and how to fix it? I see no reason why this shouldn't work!
Thanks!

Hi
First have you all set the Quicktime streaming setting, goto sys prefs/quicktime/streaming/streaming speed, set to 1.5mbps(dont use automatic)
In ichats prefs click on video and change bandwidth limit to NONE.
Restart iChat.
Do a speed test on all sides and tell us the UP AND DOWNload speeds http://www.speedtest.net/

I have a stupid error when trying to re-install itunes

after having an error with the apple mobile device support (1067) it wiped all apple programs from my computer and tried a re-install well i keep getting this error now im stuck with an ipad 2 and ipod that cant be synced at all.. and fyi i am not going to wipe my pc clean for some pos software.

These ones are tricky. But the following instructions are worth a try.
First do a complete uninstall of iTunes and related components (but don't reinstall just yet), as per the following document:
Removing and reinstalling iTunes, QuickTime, and other software components for Windows Vista or Windows 7
a. Launch regedit (Start >> Search Programs and Files >> type Regedit and open the regedit that comes up.)
b. Access the following Location: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData \S-1-5-18\Components
c. Perform the following actions
i. Right Click on Components Folder
ii. Select Permissions
iii. Select Full Control and Read Permissions options
iv. Select Advanced Button
v. Select Owner Tab
vi. Select to Change Owner to the Administrators
vii. Check the option “Replace owner on subcontainers and objects”
viii. Select OK when prompted that it may not change all.
ix. Select Apply
x. Select Apply again
xi. Exit the Registry Editor
Now try reinstalling iTunes again. Does it go in properly this time?
If you're still getting the 1067 after that, try uninstalling any MegaUpload software on the PC. Does AMDS launch correctly now?

Error when trying to re-install Adobe CC: Adobe Genuine Software Validation Failure

My subscription expired while away on holidays. I renewed my subscription and have tried to re-install without success. The first issue I had was with administrator permissions on my pc. I have fixed this but now get an error stating that the product I am trying to install is counterfeit. I have searched through Adobe's troubleshooting but I can't see anything that matches this error. My OS is Windows 7. Any assistance would be greatly appreciated!

Hi avanishdivya
I have followed these steps previously, without success. Step 1 is where I started having problems, where the download stops towards the end stating the product is conterfeit. Regarding step 2: The only other CC product I have is LR. I have followed step 2 and installed updates, then re-attempted step 1 and still receieved the same pop up. I have tried step 3 several times now (including after updating LR), each time it finishes with a pop up to install Winzip (for a fee). I don't understand why I would need Winzip to re-intall a product I was able to install without Winzip originally.
Any other suggestions?
Thanks

"Couldn't start this app" error when trying to open Action Items and any other built-in apps

Hi all,
When I try to open the Action Items app within an email in OWA, I get the error seen in the screenshot. In Outlook 2013, the frame comes up with a 404 error.
Third party apps load fine.
This is a new install of Exchange 2013 Enterprise with CU2. Everything else seems to be working fine. I have tried rebooting the server and disabling and re-enabling the apps with no luck. Can't seem to find anything in the Event Log about it.
Any ideas why this would happen and how to fix it?
"Something went wrong and we couldn't start this app"

Hi,
Could you please check the IIS log and see what’s the error code?
Try using the administrator account to log in the Outlook and see if he can see the apps successfully.
Thanks,

I get and error when trying to burn a audio CD

I am tring to burn an audio cd of something I created in Final cut pro x and when I put the files in itunes and select burn to disc it spits out the disc and says "unknown error occured (-50)". I tried using .wav and .aiff no luck with either. I already searched the forum for this problem and didn't find any thing that worked.
Vince

Tried restarting your computer?
Error -50 is a generic "communications" error message which means just about anything. It could really be a communication error with your optical drive (loose cable, bad drive, bad controller, etc.), or an issue with your hard drive (connection, formatting, a whole list of anything else you can imagine). It could also be a host of non-obvious communications.
The place to start is to keep things as simple as possible and try to test individual links in the burning process. Can you burn outside of iTunes? Have you tried a slower burn speed? (Some utilities let you turn off the laser while test burning so you don't use up a lot of discs.)

My external hard drive accidentally switched off during Disk Utility's "erase free space" process. I restarted the external hard drive and Disk Utility, but now I get the "couldn't mount disk" error when trying to finish the erase. Please help!

My external Lacie Quadra hard drive accidentally switched off in the middle of "erase free space", and when I switched it back on Disk Utility was hanging. So I Force Quit Disk Utility and restarted it. Now when I try to erase I get
"Secure Disk Erase failed with the error: Couldn’t unmount disk."
But "erase free space" seems to work...
What can I do? I'm erasing as I'm giving the drive to someone else and I wanted to wipe it clean.
Also should I use "erase" or "erase free space" if I want to wipe the drive clean?
Please help!

Sorry I don't really understand.... there are no partitions on the drive. How do I repartition it?
And should I use "erasing free space" or "erase" for wiping clean my drive of everything? Erase seems to be faster last tiem I tried.
Thanks!

Hi, I have a mid 2010 13" MacBook Pro and I keep getting a POSIX error when trying to format my new harddrive. Help?

Hi guys, one day I turned my MacBook Pro on and it was frozen at the login screen, so I did a hard shutdown and restarted it just to get a blank white screen that didn't change. So I took it to the apple store for a genius appointment and they diagnosed the problem as a failed hard drive. So I got a new hard drive and bought snow leopard installation disc since I didn't have my original installation anymore and installed the new harddrive. I go to disc utility to erase it and create a new partition on it so the Mac will recognize it as a viable option to install snow leopard on, and I get a POSIX error that says: "the operation could not be completed. Cannot allocate memory."
So I call Apple and I'm told that it could very possible be the hard drive cable which is failing me here and not allowing the connection to the HDD. So I ordered the appropriate one on Amazon for my make and model (can be found here: http://www.amazon.com/gp/aw/d/B004VSZCL4/ref=ya_aw_oh_pit)
A lot of the reviews say a new one of these cables fixed their problems with the POSIX error, so I'm wondering what you guys think of this? And if you have any other ideas that could help out?
Any advice would be appreciated.
Thanks,
Zach

Zachy,
It goes something like this...
Put your new drive in the enclosure. Use Disk Utility to format it, etc. I'd give it a slightly different name than the original. Let's say you have Old Disk and New Disk as your drive names. Use Carbon Copy Cloner to copy Old Disk to New Disk. Now you should have an exact copy, which you can test by rebooting and holding down the Option key. Choose New Disk from the list and let it boot, make sure all is well.
Shut down and physically swap the drives. Take Old Disk and put it in the enclosure. Now your system has a new disk with a lot more space and you can reformat your old disk and just use it for large files or whatever.

Receive and ERROR when trying to launch Premiere Elements 11

Out of the Blue, I am suddenly unable to open Priemere Elements 11, the organizer works fine, but if I slect NEW Project from the welcome screen I get the following errors: A dialog box named "Premiere Elements Debug Event" with the message of "Premiere Elements has ecountered an error....
[..\..\Src\Core\Preferences.cpp-388]
The only option on this error is to hit "Continue", at which point a second window pops up with a Runtime Error...
I have uninstalled, rebooted and then reinstalled but there is no change. Has anyone elese seen this problem... thanks in advance for any help.

If you want to give some troubleshooting a try, I will stay with you until we get that Premiere Elements 11 Windows to work. I will have lot of questions because I believe the answers are in the details. Often I write problems with the same symptoms can (often do) have different causes. So, I look at each case for details specific to it.
1. How long have you been running Premiere Elements 11 Windows 7 64 bit without this problem: few days, few weeks, few months, never worked? The usual drill...do you have the latest version of QuickTime installed and are you working from a User Account with Administrative Privileges? Are your video and audio card drivers up to date?
2. What do your computer resources look like, available RAM, free hard drive space (derived from just Local Disk C or using a supplemental drive for scratch disks and video storage? Where are your scratch disks directed and how much free hard drive space is at that location? (See Edit Menu/Preferences/Scratch Disks.) Besides your ccleaner maintenance, have you checked for Adobe Folder previews and conformed audio pile ups? Have you cleaned the Media Cache Database (See Edit Menu/Preferences/Media/Media Cache Database.)?
3. You say the problem happened out of the blue. Any new software, plug-ins, codecs, and the like installed around the time that the problem set in?
4. I would like to see you get rid of the Welcome Screen as your point of entry to the program. To that end, right click the Premiere Elements 11 Desktop icon, select Properties, select Open File Location. That will take you to a file named Adobe Premiere Elements 11.exe. Select the file next to it named Adobe Premiere Elements.exe, create a Desktop shortcut to Adobe Premiere Elements.exe, and use that Desktop shortcut thereafter to open Premiere Elements 11.
5. I would also like to explore other ways of opening the Premiere Elements new project depending on results. One example...can you open a new Premiere Elements project from the Elements Organizer?
5. If possible, download and install the free 30 day tryout of Premiere Elements 11 Windows from Adobe and determine if that will install for you from the Premiere Elements as well as the Elements Organizer interfaces. Adobe allows only one download of its tryout product version whether you have used the product 1 or 30 days. So, if you have gone the tryout route, this idea isn't going to work unless Adobe makes an exception. But, I do like this idea for troubleshooting purposes.
MBolton never did follow up to a conclusion on the thread that kglad kindly referenced. There were other avenues to explore. I look forward to the opportunity to assist you in your Premiere Elements troubleshooting here. I am no longer visiting nor answering questions at the web site where MBolton and I sought to find an answer to this issue.
Thanks.

I have tried to locate it in my toolbar and applications to uninstall it from there with no luck, it has completely disappeared. Not in my trash, nowhere. Not sure what else to do. I am running on Mac OS X 10.7.5. When I have Adobe check to see if it is installed on my computer, it says that a previous version is installed, 16.0.0.

Repaint Error when trying to scroll in Browser? PLEASE HELP

I'm getting a repainting error ( the applet messes up and can't refresh the controls) when I try to scroll down in the IE 5.5 browser to view the rest of my applet. I noticed while scrolling, the applet does not seem to be repainting the controls properly in the exact spot as if the applet is moving faster then the scrollbars. I have no idea on what could be causing this problem. If anyone could help, I would greatly appreciate it.
System Configuration:
Using the java Plug-in 1.3
IE 5.5
on a Windows box using IIS 5.0 / Windows 2000
Applet is straight forward, has a couple buttons, adds buttons to a JPanel and then adds the JPanel to the ContentPane. And the .html applet size is 700 pixels in height to test the scrolling of the applet, but the applet in general is only 400 pixels in height.

A12E3 error when trying to update/install CC Desktop App

I couldn't update the Adobe Creative Cloud Desktop app because it displayed an error A12E3 during install, so I uninstalled the app with the Adobe Uninstaller I found in its application folder. Then I tried re-downloading the latest Adobe CC app and installing it but the issue was the same: error A12E3.
Can you help me?
Oh! Maybe I should also say that i'm on a MacPro and my OS is OSX 10.9
Thanks a lot

Solution 2 from this help article http://helpx.adobe.com/creative-cloud/kb/unknown-server-error-launching-cc.html should resolve the problem.

Unknown Error - When trying to Upgrade to OS X Mavericks

I have a MacBook Air: 1.8 Ghz, 4 GB 1600 MHz DDR3. Running OS X 10.8.5 (Mountain Lion)
In the App Store, I see the free Upgrade available for OS X Mavericks.
I click on the free upgrade button to the right of the upgrade notification and then it asks me to enter my apple ID password (which I do) and it throws 2 errors
1st error - Unknown Error
I click OK (because thats the only option available)
2nd Error - We could not complete your request. There was an error in the App Store. Please try again later. (4)
I click OK (again because that is the only option available).
Cannot download the upgrade. Anyone know what these errors relate to?
Thanks!

I have home network (AT&T broadband connection - standard tier level/bandwidth)
I have been trying over my own WiFi since I can easily stream movies with no issue (Netflix, Vudu, etc.).
BTW - Macbook Air does NOT have any cat5 network cable connetion hardwired for this device. It only has firewire which is generally used for transferring data between 2 devices. So I'm not sure how I would connect any other way to my network than through WiFi.
