(Central) NY State of mind
There is a workaround for this (I did this for PDFPen Pro before the new version was released and worked fine for me - use at your own risk, don't blame me if you screw something up by not following steps properly):

1. Open Keychain Access (/Applications/Utilities/Keychain Access)
2. Select "Keychain Access > Certificate Assistant > Create a Certificate…" and create a self-signed certificate (use a name without spaces and change “Certificate type” to “Code Signing”)
3. Find your newly created cert in your list and select it, then do File > Get Info on that certificate
4. select "Code Signing > Always Trust"
5. In terminal, type "sudo codesign -s <CERTIFICATE_NAME_HERE> -f /Applications/
(obviously change the app name if you're signing a different app - and put just the cert name - no brackets)

check “Let me override defaults” in order to enter a date a few years into the future - otherwise its default is one year.

…this should re-sign the app with your own certificate, and you're set.

I could stand some NY myself. It's been a while.
Thanks for the tip. Likely I'll use it.
