Y'all: I fixed this months go, it's just not in the current builds (but now in the current master):

https://github.com/pure-data/pure-data/pull/838

Someone sent an email to pd-dev about it, I fixed it, and they tested the fix. If you want to test on Catalina, try the "Pd-0.52-2-signed.zip" on http://docs.danomatika.com/pdbuilds/0.51/

Also, everyone please stop the constant FUD about forced upgrades. We get it, you use the OS you prefer and I will use the one I prefer.

(had replied to this earlier, but to alexandre only, by mistake.)

that annoying behaviour is called notarization and should protect the galaxy from evil bananas.
the delay could be caused by the notarization process checking against an internal database of good actors and in case there is no entry trying to do so online.
i´ve heard you can kill all this by turning off SIP (sytem integrity protection), but i am on mojave, which is slightly less annoying.

in addittion, if some brave soul on cataline wants to check if that assumption about notarization is true, there is some info here:

so the test would be to measure with and without that stuff…but thats certainly not a generally recommandable case.
