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?

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?

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.

Digital signature on the update is missing? So cannot load updates for MacBook or synch Ipad - Help

Digital signature on the update is missing or invalid.This message appeared when trying to up date ITunes in order to Synch with a new IPad.

Wondering how to download from update site? I have 10.6.8 and need to upgrade, do I jump to the most recent version, or to 10.7?
Also, if the automatic update doesn't work, what do I do to use something from the download site?

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.

Cisco support lower encryption type. Every new windows encrase cryptograpgi that IE support by default. Look IE about to see type 64 or 128 or 256…
On xp will work good, but we are now in era of win 8 with IE that support by default 128 or 256 depending home or server version.

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.

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.

Adobe AIR update has no digital signature. Is this normal?

I installed Adobe Air and it says it needs to update. But when I click Update, my firewall says there is no digital signature. So, I don't kow if this Adobe product is OK.
Every time, when I surf the Web, I get an Update Adobe message. I don't know if I should update. Last time I did, my computer crashed. It keeps crashing now every 45 minutes. This is why I tried to update Adobe to start with.
Thank you in advance for any help in dealing with this Adobe update with no digital signature.

This seems to be the case, as the two products are developed by the same team.

Digital signature in Software Update

I have been trying to Update my Tiger version 10.4 to 10.4.3 using Software Update. After the files download, I get a comment that says the digital signatures are not correct the files cannot be installed. What does this mean?

"The digital signature for this package is incorrect. The package may have been tampered with or corrupted since being signed by Apple"
My iMac Flat Panel updated the most recent upgrade just fine, but my iMac Classic showed the above error message.
I tried several times over two days but no go ... finally I downloaded the OS X 10.4.4 file on Apple's Support site http://www.apple.com/support/downloads/macosxupdate1044.html ... it installed just fine. Then I went to Software Update and this time QuickTime, iPhoto and iPod updates installed without error.

Mac G3 w/ Tiger 10.4.3 update problem/issue "digital signature incorrect"

I have an old G3 on which I reloaded 10.4.3 yesterday (Retail copy). It did not go very smoothly. This is the 3rd install; 1st install was several months ago with this chip, 2nd install was shortly after that with a PowerLogix chip which didn't work. I put the old chip/processor back in yesterday and reinstalled again. I don't remember if I messed with the firmware or not with the previous installs.
PowerMacG3, Model 1.1, PowerPC750, 256meg, BootRom 1.1.1f4
The software updater tells me I need to update to 10.4.8. When I proceed with this, the system downloads the software OK, but when it attempts to install the update I get the following error:
The update "Mac OS X Update Combined (PowerPC) can't be installed.
The digital signature for this package is incorrect.
The package may have been tampered with or corrupted since being signed by "Apple".
Any ideas as to how I resolve this? Could the problem be with the OS registration, and the different chips?
Thanks in advance.

Thank you for replying to my post.
Yes, I can do a nozzle check with the USB unplugged,
and I still get poor results on the C82 and nothing
on the C86. I just can't believe both printers are
broken. The C86 is new, and they were both working
fine previously.
Epsons are notorious for getting their print heads clogged. Run the clean print head routine a few times. If that doesn't work, return the new printer 'cause it's dead out of the box. The old printer, well, once Epson print heads get to a certain level of clogging, nothing will unclog them. Toss the printer and get a new one. Hint: HP and (some) Canon printers put the print heads in the ink cartridges, while Epson and (some) Canons have the print heads in the printers. Machines which have the heads in the carts also have an easy fix for severe clogs: toss the cart. Warning: HP printer drivers stink.
If you don't need colour, you might think seriously about getting a low-end laser.
I just got the C82 to print readably, but still
completely missing magenta and with minimal
fuzziness. This was just dumb luck though, from
letting the printer sit idle for several hours.
It's still clogged. Clean the heads a few times again, or just toss it.
And yes, I've tried setups through the Print & Fax
pref pane, which usually works better than going
through the Printer Setup Utility which tends to
freeze and crash.
I wish I could afford to just buy another printer.
But I'm still worried it's something to do with my
computer, since both printers are having problems
simultaneously, and they're both really good
all-purpose printers.
It's not your machine. It's Epson.

You have 10.6 on that machine, I suggest you stick with it for performance, third party hardware and software reasons as long as possible.
Consider 10.8 (not 10.7) when it's released, because 10.7 and 10.8 will require a new investment in software and newer third party hardware as it requires newer drivers the old machines won't have. (forced upgrade because of software, really nice of them)

Far as your Safari problem do these things until it's resolved:
1: Software Update fully under the Apple menu.
2: Check the status of your plug-ins and update (works for all browsers) also install Firefox and see if your problems continue. You should always have at least two browsers on the machine just in case one fails.

Digital Signature update after new documents created on customizing

Is there any standard report to update old document with signature after new changes on SIPT_NUMBR_SD_V which added new document types?
I mean, if we move to live system today 2 new number ranges for billing types, the new invoices created will be on digital signature, but what about the old document created before the transpor of customizing?
Regards,

Hi dude,
I appreciate that your sharing your experience and solution here. And, I would report it through our internal channel. Thanks again.

Software Update - digital signature incorrect

I have several update packages that were consistently reporting the error:
*The update "xxxxxxx" can't be saved.*
The digital signature for this package is incorrect.
The updates are:
iLife Support 9.0.3
Java for Mac OS X 10.5 Update 4 1.0
Safari 4.0
Several other updates (eg. recent iTunes and QuickTime) downloaded and installed OK.
I tried all of the following to no avail:
Repair disk permissions
Reinstall 10.5.7 combo package manually
Delete Software Update preferences & cache files
Multiple restarts
Finally I tried running Software Update under a fresh admin account and they downloaded OK. (Different issue that the Java Update later said it couldn't install).
So seemingly this is related to something in my usual admin account. Does anybody know what other preference files I should look to delete, or any other hidden setting that is affecting the digital signature checking?

I tried all of the following to no avail:
Repair disk permissions
Guess Carolyn didn't notice this.
This was happening fairly frequently about a month ago when 10.5.7 came out. The Apple servers were overloaded apparently and some incomplete downloads occurred so some type of checksum prevented running the update. Waiting and downloading later seemed to be the best solution.

Perhaps by the time you did all the troubleshooting steps, if you tried it from the original admin account it would have downloaded correctly.
