Apple's digital signature

I tried in the iTunes forum, but didn't get very far, but now suspect the problem's at my end, and probably with Snow Leopard.
I've been trying to install updates. At firt it was just iTunes, and some people thought it's because the servers were overloaded with the launch of iOS 5.1.
I tried again today, for iTunes and Safari, and I get this message:
The digital signature on the update is missing or invalid. The update may have been tampered with since being signed by Apple. The update will be downloaded and checked again the next time that Software Update runs.
It downloaded the full 130Mb (or whatever) and only told me at the end!
I can't think what I've done to my computer to make it not recognise the Apple signature.... everything else seems to be working fine.
If anyone has any ideas, I'd be very pleased to hear them.
Thanks.

This fixed my issues also
"checked my time / date panel after realising it was wrong in the menu" it was off more the a day can cause this.

We've just had a leap year and a time change.... I just checked my time / date panel after realising it was wrong in the menu. Sure enough, the "auto update" was not checked, which meant it had got out of sync with the date and the time.
I checked it, both updated, went back to software update, and they downloaded / installed without a hitch!
Hope this helps someone else.

I can't run Itunes! After installing Itunes, I receive a message saying that Windows could not verify Apple's digital signature and it closes.

Pls HELP me! I can"t install it Itunes on any of my computers. After downloading it ( Run now or Saving it) it will no run because I keep receiving a message saying that Windows can not open this file because it could not verify Apple's Digital Signature. I have changed my internet security settings to allow downloads from unverified websites but it will not allow me to run Itunes. I had an older version of Itunes so I tried to install the update and it wouldn't work because so the same message about not being able to verify the digital signature. I uninstalled Itunes and Quicktime and all other Apple programs on my system. Then I tried to download it again... no luck the same message came up again. I then went to my other computer that NEVER HAD ANY APPLE software on it and tried to download Itunes. It gave me the same message. Please help me, I'm going crazy tring to figure this out.

I had this same issue occur today during update, searched and finally tracked to problem with windows registry. Used online version of windows registry tool "Fix It" (can also download portable version for offline check. I selected Apple updater utility from list to fix and it did it's thing. Returned to my downloaded 10 iTunes adn isntalled perfectly fine.

Mac OS 10.5.8 update combined can't be saved, Apple digital signature incorrect.

Hi,
I have tried, several times, to update OS 10.5.1 to 10.5.8 using Apple's online software updater. It takes 20 minutes to download the 768 mb package but then
refuses to save with the following message. 2.16 GHz + 2 GB ram.
Mac OS X can't be saved. The digital signature for this package is incorrect. The package may have been tampered with or corrupted since being signed by Apple.
I need to update to 10.5.8 so I can then install 10.6 etc.
I have tried to install 10.6 without updating to 10.8 but it shows the message: Mac OS X can't install on this computer. I assume this is because I have not, and
cannot, updated to 10.5.8.
Any help would be appreciated.
Apple want me to pay $20 to advise them that their software package has an incorrect digital signature, even though it has only just been downloaded from their servers. No email address to advise Apple of problem.

Hello, it's generally one of two thinks that cause this, but it is a bad download.
Try Ethernet instead of Airport if possible.
Disk can be corrupted...
Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
Try getting it direct instead of SWUPDate...
Repair Permissions afterwords, reboot.

Apple mail strips my digital signature from pdf attachments

I communicate with clients through email. I send reports which contain a picture of my signature and a digital hass. Apple mail strips the signature from the pdf files as I attach them.
An aside. I use mobile me and the idisk server. All documents located on the idisk are also stripped of the signature block.
This is not a problem if I use outlook, which I guess I have to switch back to again.
What does apple have against a digital signature

I sign the pdf with a digital signature which includes a picture of my written signature. When I attach it to Apple mail or upload to mobileme, the signiture disappears. My clients see nothing. When I go back to the email in the sent box and open the pdf in the email there is no signature. When I open the original pdf the signature is there
This problem does not exist in outlook 2011, but would have liked to use mail as outlook does not support caldev
I don't know if I can explain it any better.

Digital Signatures on PDFs won't show up on apple, ipad, or iphone

There's another post with the same title, but not the same problem.
We provide our clients with 1000's of State PDFs, and some of them we need to sign. So we give them to our clients with our digital signature on them.
We make the signature with acrobat pro... All PC users can see it just fine, but EVERY apple user can't see the signature.
We've even borrowed an apple laptop to see if we could see it there. Somehow Apple blocks the view of the signature....
You can't see it, or print it. I have had this happen on PCs when we've done "Stamping" or used the handwriting tool, because it puts the handwriting over the pdf, and then the end user would have to go into their print options and click the "Print with markups" option, but this is different. No PC users ever have to adjust their printing preferrences.
Anyone know if there's an adobe or acrobat download i could send Mac users along with the pdfs to make these visable?
Thanks for your help...

The PDF viewer named Preview that comes with the Mac does not support digital signatures. Adobe Reader/Acrobat do, so you could try to convince them to install Reader, but it's not available for the iPhone or iPad.

Update on 10.6.8 fails due to digital signature on update is missing

wanting to install the Parallels version 10 and it won't work on 10.6.8 version of my Mac OS so I learned how to go to the software update which indicates an update is available. When I go ahead and load the update it runs fine and then stops with a message that the Macbook Pro EFI Firmware Update can't be saved. It says the digital signature on the update is missing or invalid.
I don't know if the digital signature is on my computer or the update? I would upgrade to a more recent version of the OS but don't know what will work.
Can anyone help?
Dan

Parallels 10 isn't compatible with 10.6 according to the web site.
Mac Requirements
Hardware:
A Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor (Core Solo and Core Duo processors are no longer supported)
Minimum 2 GB of memory (4 GB of memory is recommended to run Windows 7 in a virtual machine or if your host OS is Lion)
About 850 MB of disk space on the boot volume (Macintosh HD) for Parallels Desktop installation
About 15 GB of disk space for each virtual machine
Software:
OS X Yosemite 10.10 or later
OS X Mavericks 10.9.4 or later
Mac OS X Mountain Lion 10.8.5 or later
Mac OS X Lion 10.7.5 or later
Check that your computer is compatible with Mountain Lion/Mavericks/Yosemite.
To check the model number hold down the option/alt key, go to the Apple menu and select System Information.
MacBook (Late 2008 Aluminum, or Early 2009 or newer) model number 5,1 or higher
MacBook Pro (Mid/Late 2007 or newer) model number 3,1 or higher
Your Mac needs:
OS X v10.6.8 or OS X Lion already installed
2 GB or more of memory (More is better - 4 GB minimum seems to be the consensus)
8 GB or more of available space
Check to make sure your applications are compatible. PowerPC applications are no longer supported after 10.6.
Application Compatibility
Applications Compatibility (2)
Do a backup before installing.
If you can/do upgrade, I recommend you make a copy of the installer and move it out of your Applications folder. The installer self-destructs. The copy will keep you from having to download the installer again. You can make a bootable USB stick to install using this free program.

Note - Mavericks is no longer available.

Please let me figure out how to allow windows 7 to see my ipad and for itunes to work. It is looking for a digital signature!!

How to get my ipad to sync with windows 7 when itunes does not see it and in device manager it says that it needs a digital signature and when I look at devices it says apple camera not ipad and it's not working.
Any ideas?

You need a third-party program. The following includes listing such programs. It also included instructions form making this computer your syncing computer

Digital signature issues with windows 7

My iphone won't open on my computer like it use to. This all happened when I updated my itunes software. I get a digital signature error. Apple says its a Windows problem. Windows says its an apple problem. Someone please help.

Perfect, thanks.
I see that one's got an SPI firewall:
http://www.netgear.co.uk/pdfs/dgn2000ds18july08
By way of experiment, try disabling the firewall and doing another iTunes download. Are you able to get a working installer this time?

UPGRADED 10.4.11 ON MACBOOK PRO TO 10.5, NOW UPDATES TO 10.5.8 WILL NOT SAVE, "DIGITAL SIGNATURE DOES NOT MATCH". ANY IDEAS.

UPGRADED 10.4.11 ON MACBOOK PRO INTEL TO 10.5.1 (FAMILY PACK VERSION), UPDATES TO 10.5.8 WILL NOT SAVE DUE TO, "DIGITAL SIGNATURE DOES NOT MATCH". ANY IDEAS? CAN I UPGRADE TO 10.6.1 WITHOUT SAME ISSUE.

Well, not sure if having the disk in a firewire case or over a network would have made a difference.
The solution of making a disk image as in article http://support.apple.com/kb/TS2664 was what worked for me.
After, mounting the disk image the Migration Assistant completed without errors. So far everything seems to be working like it did on 10.4.11.

"digital signature on the update is missing or invalid" 10.6.8 combo 1.1 from 10.6.3.

Also got posted in '10.3 or earlier' community, where other posts are regarding this issue ... I get "digital signature on the update is missing or invalid" trying to install 10.6.8 combo on MacBook currently using 10.6.3. Have used Disk Utility, Restart, Shut Down, with no luck. Used Software Update from 2 different avenues, and also downloaded from apple site. Also searched support.apple, no luck. Thoughts?

ok. i've done the moving of those plist files, restarted and tried again. it hasn't worked, but thank you for your suggestion. i got excited for a minute or two.
it now says An unknown installation error occured. The installer encountered an error that caused the installation to fail. contact the software manufacturer for assistance.

Itunes wont install on vista, No digital signature

I had a problem were Itunes would not update or anything Apple related (quicktime etc) so i deleted Itunes and tried to run it as a fresh copy.
Yet when i download it and try to run the application i get the box from windows asking me if i want to run it, but in this box next to publisher it says unknown.
When i click run nothing happens. The box disappears and thats that.
If i click on the application and go into properties and go into digital signatures it says the digital signture is not valid. Ive tried downloading it with Explorer, Firefox incase that was it. I have even done a clean install of windows and tried to install itunes first incase there was a conflict.
Can anyone please help because its driving me nuts!

Mr. Peck-- Would like your advice re: where to post this question. I cannot update ITunes and Quicktime to the newest version using apple update in the windows environment. I have tried disabling antivirus software without help. Error is that it is not receiving a "valid signature." Installation on the mac side of updated quicktime and Itunes works fine. Windows version is XP SP3-- with appropriate updates.
Is there a solution that you know of? Where would you suggest posting this question?
Thank you,
Mark D

Save as PDF, allow digital signatures in Reader

After saving the pdf from Pages, security permissions do not allow for digital signatures in Adobe Reader. How do I change this without having to use the full version of Adobe Acrobat?
...Bruce...

Hi Bruce,
Although you are creating the pdf from Pages, it's not Pages that is actually doing the conversion. Pages (and any other application for which pdf is not the 'native' file format) is using code that is part of the OS X package to convert the document to a pdf file.
If that code includes the capability of allowing digital signatures, Apple hasn't bothered to mention the fact in the Pages '09 User Guide. The only pdf option listed there for Export PDF is reduction of file size by resampling image files.
As the conversion is done with OS X bundled code, shared by all applications, you might find more useful answers in the Mac OS X v10.7 Lion community.
Regards,
Barry

Digital Signatures and Encryption in Yosemite Mail

After upgrading to Yosemite, I am having difficulty using the Mac Mail app to send digitally signed and encrypted email.
Before the upgrade to Yosemite, I was able to send signed and encrypted emails using certificate/keys in my keychain using both the Mac Mail app and Microsoft Outlook 2011 for Mac.
After upgrading, I am still able to send signed and encrypted message in Outlook, but the Mac Mail app gives the following error when I attempt to send a signed email:
'You don’t have a trusted certificate in your keychain that matches the email address “XXXX@XXXX”. Without a certificate, you can’t sign messages sent from this address.' (Actual name replaced)
When I look at my certificates in my keychain, a certificate is available with "Usage: Digital Signature" that has the email address from the error message "XXXX@XXXX" with exact case in the RFC 822 Name.
Another interesting piece of data that might help track this down is that when I first launch the Mac Mail application, the Mac Mail application is able to successfully decrypt emails that have been previously sent encrypted to me. HOWEVER, after I attempt to send an email and get the "You don’t have a trusted certificate..." error message, these emails are no longer able to be decrypted. I get the "Unable to decrypt message" header above the message and the content of the message is just a "smime.p7m". If I close the mail application and restart it, these encrypted message are once again decrypt-able until I attempt to send a message.
It almost seems like things are working until mail tries to access the keychain.
I have attempted to delete my certificate and keys from my keychain and then adding those items again.
I have attempted to close the mail application and reopen it.
I have attempted to reboot my computer.

1. I want to confirm that this is still an issue for me in 10.10.1 and mail Version 8.1 (1993)
2. I have another data point.
At my office I have wired networking and wireless networking available. Primarily I utilize the wired networking for access to network drives, etc.
When using the wired networking, I experience all the problems that have been catalogued in this thread. Can't sign, can't encrypt, can't close the compose window after the mail program fails to find my certificate.
However, when I switch to wireless networking before starting the mail application, digital signatures and encryption seem to work! This is pretty weird behavior. Make sure to restart mail if you were previously wired.
Here are some theories:
Something to do with OCSP? When I am wired vs wireless I am on different ip subnets and subject to different firewall rule sets. Perhaps OCSP is trying to determine the status of the certificate and failing?
Here are some things I have tested:
I switched to a different official apple brand thunderbolt to ethernet adapter with no change in behavior
I disabled wireless and disconnected my wired network. So no network access at all. Signatures and encryption work! The message obviously does not send, but it appears in my outbox and I don't get the signature error. When I reconnect my wired cable, the message sends successfully and appears as encrypted in my sent folder!
I have attempted to disable OCSP by using "Keychain Access --> Preferences --> Certificates Tab --> OCSP (OFF) and CRL (OFF)" but this hasn't made a difference in the behavior of wired networking.
Ran a TCPDUMP on traffic to the OCSP service but didn't see any traffic when I attempted to send a message and received the signature error
I am pretty stumped on this. This is very odd behavior
Does anyone else experience this behavior?

This was traced back to one of the ini files still having a folder name from the last instance installed (i.e. SERVER6).
So it is fixed
