The Update Is Improperly Signed

What do i have to do now?


I went to the Toast 11 update page ( http://www.roxio.com/enu/support/toast/software_updatesv11.html ) and downloaded the previous version (11.0.4), installed that version and then updated to 11.1 (10687) after opening the newly installed Toast 11.0.4.


I still crashed a few times, but after a few restarts of Toast it has worked fine. Pretty strange behavior since ML came out, for sure!


Good luck!

today i was prompted for the new update, i have the 11.1 (1063) and was prompted for 11.1 (1067) but after the download is complete (88mb) i get his error:

The update is improperly signed.

What do i have to do now?

it seems i am having the exact same problem as the first comment. i have not tried going back to 11.04. been having trouble with the last update as well. did anyone contact roxio help by way of technical support. I have already sent an email to them showing that this is happening.

There is no full version on MacUpdate but only the updater, 96mb: http://www.macupdate.../toast-titanium while the full version should be about 450mb..


But i found out that:



MacUpdate Note: The original 11.1 update (1063) contained a few bugs that the new 11.1 update (1067) resolves:

  • Resolved digital signing issue which occured on some OS versions
  • Resolved issue where updating would generate invalid signature message
  • Customers still encountering this error will need to download a full version of Toast 11.1 from our software update more...
