I am using Mac OS X 10.7.5 as of now and when I am trying to upgrade to Mavericks, it is throwing error "The product distribution file could not be verified. It may be damaged or not signed".

I am using Mac OS X 10.7.5 as of now and when I am trying to upgrade to Mavericks, the App Store is throwing error "The product distribution file could not be verified. It may be damaged or not signed".
Is there anything I should do differently? Is anyone else facing the same issue?
Kindly help.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.
Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects.
Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it. The headings “Step 1” and so on are not part of the commands.
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
Launch the 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 “sh” and press return. You should then get a new line ending in a dollar sign.
Step 1
Triple-click anywhere in the line of text below on this page to select it:
kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}' | open -ef
Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting. A TextEdit window will open with the output of the command. If the command produced no output, the window will be empty. Post the contents of the TextEdit window (not the Terminal window), if any — the text, please, not a screenshot. You can then close the TextEdit window. The title of the window doesn't matter, and you don't need to post that. No typing is involved in this step.
Step 2
Repeat with this line:
{ sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix\.cron)|org\.(amav|apac|cups|isc|ntp|postf|x)/{print $3}'; echo; sudo defaults read com.apple.loginwindow LoginHook; echo; sudo crontab -l; } 2> /dev/null | open -ef
This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step.
Step 3
{ launchctl list | sed 1d | awk '!/0x|com\.apple|org\.(x|openbsd)/{print $3}'; echo; crontab -l 2> /dev/null; } | open -ef
Step 4
ls -A /e*/{cr,la,mach}* {,/}Lib*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts .la* 2> /dev/null | open -ef
Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting.
Step 5
osascript -e 'tell application "System Events" to get name of login items' | open -ef
Remember, steps 1-5 are all copy-and-paste — no typing, except your password. Also remember to post the output.
You can then quit Terminal.

Type or copy / paste: /Library/Preferences/SystemConfiguration
Click Go then move the NetworkInterfaces.plist file from the SystemConfiguration folder to the Trash.
Relaunch the App Store. Try purchasing Mountain Lion.

I tried to update the latest software update for my MacBook pro (which was on 10/12) and after it started to update it restarted like normal but when it started back up it was running painfully slow and none oft programs will open.They all quit unexpectedly. iTunes microsoft word all of them quit unexpectedly. Help!

Exact same problem with my 2010 MBP 2.4ghz 4gb ram 10.6.8. iTunes said update was needed, Software Update ran with various updates including a security update, truthfully didn't pay much attention, I always install the Apple updates. After the restart it took 3-4 times longer than normal to get to the login screen, same to get to the desktop but I'm familiar with that occurring on update restarts. Unfortunately it got worse from there. Performed a full shutdown and startup. Same long boot. After the desktop finally loads every mouse button press received a 2 minute beachball. I use menu-meters and both processors are under 10%. Waited a few minutes for disk utilities to launch, repair permissions estimates 3 hours for a typical <10 minute process. Activity monitor shows nothing over 10% CPU most of the time however ReportCrash pops to the top often. Any suggestions would be greatly appreciated. BTW zero problems until this update.

(1) Download the Windows Installer CleanUp utility installer file (msicuu2.exe) from the following Major Geeks page (use one of the links under the "DOWNLOAD LOCATIONS" thingy on the Major Geeks page):
http://majorgeeks.com/download.php?det=4459
(2) Doubleclick the msicuu2.exe file and follow the prompts to install the Windows Installer CleanUp utility. (If you're on a Windows Vista or Windows 7 system and you get a Code 800A0046 error message when doubleclicking the msicuu2.exe file, try instead right-clicking on the msicuu2.exe file and selecting "Run as administrator".)
(3) In your Start menu click All Programs and then click Windows Install Clean Up. The Windows Installer CleanUp utility window appears, listing software that is currently installed on your computer.
(4) In the list of programs that appears in CleanUp, select any iTunes entries and click "Remove", as per the following screenshot:
(5) Quit out of CleanUp, restart the PC and try another iTunes install. Does it go through properly this time?

Software Update - could not be verified and expanded

I tried to do a search on this, but didnt initially find anything.
Software Update runs, finds updates to download, I click Install Updates, they are downloaded but then I get an error that reads, The update "XYZ" could not be verified and expanded correctly. Make sure you have permissions to write to /private/tmp/501/temporariyitems, then try again.
I tried to chown the permissions on that directory, no difference. I then did:
sudo su
cd /private
rm -r tmp
mkdir tmp
cd /
ln -s /private/tmp tmp
...and now the error message for software update has become: blah blah blah, Make sure you have permission to write to /tmp/com.apple.SoftwareUpdate, then try again.
Can anyone help? This computer has been sitting dormant for a couple of months and I wasnt the main user before so I can only assume this has been going on for a while and is not a new issue. Thanks!!!

Do you have an admin account on the computer?
Instead of Software Update, I suggest that you download and install 10.3.9 Combo Update. Remember to Repair Disk Permissions before and after installation.
Happy Holidays.

Get more information about your computer. Go to the Apple in the upper left corner of any window, then "About This Mac". Write down what it says about "version"and report that here. Now continue to "More Info..." Copy and paste the information here, but omit the serial number and Hardware UUID (if present).
If you have a PPC Mac you cannot sync your idevice without a newer computer. See the end of this post for options.
If it says you have an Intel Mac you can upgrade to Snow Leopard, but check system requirements first:
Snow Leopard 10.6 Technical Requirements - http://support.apple.com/kb/SP575
You can buy Snow Leopard at:
Snow Leopard disc source - http://store.apple.com/us/product/MC573Z/A/mac-os-x-106-snow-leopard
After installing run the updater to 10.6.8, then upgrade iTunes.
Jan. 2014 post by Kappy on doing all this: https://discussions.apple.com/message/24599931
Options if you cannot upgrade: iTunes Store purchases can already be downloaded directly. Use iTunes Match to put non-Store music in iCloud, then download to your device from there. Backup your device directly to iCloud over a wireless connection. Photos can be downloaded from the Camera Roll using iPhoto or Image Capture.

The update "iTunes" could not be verified and expanded correctly.

Hi all,
I was tryng to upgrade to the latest version of iTunes and I got this message
*The update "iTunes" could not be verified and expanded correctly.*
*It also says: Make sure you have permission to write*
*to /tmp/501/TemporaryItems.com.apple.SoftwareUpdate, then try again.*
Any ideas what that means?
Thanks,

HT1338 my MAc Book PRO 13" Retina display will not update. It crashes every time I try to do an update. I have sent in the information on each update but so far nothing back from Apple.

my MAc Book PRO 13" Retina display will not update. It crashes every time I try to do an update. I have sent in the information on each update but so far nothing back from Apple. Also it does not matter what I am trying to update, the operating system, and application, each caused the same crash. This mac book is less than a month old.

That is the highest you will be able to go with 3g. You need 3gs or 4 to go any higher (multi processors and more memory needed). Version 4.2.1 marks the end of your updates for that device.

Configuration could not be verified - is the username or password wrong?

I run Windows 7 Professional 32 bit. Downloaded and installed Tbird 31.1.1 today.
Logged in to my Gmail account using copy and paste of my username and password from a file. I enabled IMAP. Logged out of my Gmail account.
Turned off Windows Firewall. My task bar is red at me with 1 important message: Windows Security Center Service (Important) The Windows Security Center service is turned off.
I have no antivirus software installed other than Microsoft Security Essentials (MSE.) I went to Control Panel | Programs and looked, finding nothing. This was to be expected because I haven't installed antivirus software before.
Restarted in Safe Mode with networking, which seems to turn off MSE.
Back in TB, I clicked Create a new account: Email. Entered my name, Google E-mail address, Google password. I used copy and paste to enter the same Gmail address and password that worked for my login minutes previously. It autopopulated the fields. I clicked Done. After a few seconds, got the error message:
Configuration could not be verified - is the username or password wrong?
So with no antivirus software, no firewall, and restarted in safe mode, what is the problem?
Thanks.

I tried again today without success. I have been able to get Tbird to download mail from a non-Gmail provider but not send messages with this non-Gmail account.
I have enabled 2-factor authentication in Gmail for this account. I followed the instructions from Toad Hall at 9/20/14 1:28 PM here https://support.mozilla.org/en-US/questions/1020778
I got the password from Google and went to Tbird. I went to Tools | Options | Security | Passwords and deleted all the Gmail entries. I shut down and restarted Tbird. I highlighted the Gmail account I created and hit F5. Nothing at all happened. I deleted the account and tried to recreate the account again. I got the familiar error message that Tbird cannot set up the Gmail account. So now what?

I get the following error message when I try to receive e-mail in this hotmail account: "Configuration could not be verified – is the user name or password wron

I have tried to add a hotmail account to Thunderbird because my Internet provider will stop e-mail support in the near future. I was able to add a hotmail account to Thunderbird, but I get the following error message when I try to receive e-mail in this hotmail account: "Configuration could not be verified – is the user name or password wrong?" (The hotmail website receives the e-mail.) User name and password is certainly correct. I have a 8.1 OS. Thank you.

got an anti virus that thinks it should scan email. Turn that function off.
Have a firewall, check that Thunderbird has full internet access, not some Auto rubbish that somehow fails.

Quicktime could not be verified and expanded

I get the update that there is a new QT version to be installed.
When I click ok to download it and install it, it downloads fine and then when it tries to install I get the error message :
"Quicktime could not be verified and expanded. Make sure you have permission to write to /tmp/501/temporary items/com.apple.softwareupdate"
All other software updates install just fine.
I have run the disk utility several times to restore permissions to the drive.
I have 10.3.9 with 5.5Gb available.
HELP

Hi, perhaps you installed QT as a different user (maybe an admin user)? I've had some updates that I had to run as an admin user, or as root because of permissions, though not QT. Try being an admin user or root and downloading this upgrade. You should have no problems.
