This is happening in version 0.51-4 as well as in the latest 0.55-1.
How far back should I go?

Since switching to my new macbook with osx 14.6.1, I'm experiencing the following weird behaviour:
A patch doesn't open directly. When double clicking the patch, first the Pd window opens and nothing else happens. Only when double clicking any patch again when Pd is already running, it opens. This happens with every patch. and I get the message "macOS: can't load library".

Also, Pd often crashes, even when running simple patches, like ten automatonism modules with low cpu. This wasn't the case in my older mac and linux systems.

Any advice on what to do?

I tried the osx make file, but probably I did something wrong there.
The author was mailed yesterday.

yes, can't run extended here. (64 bit osx Catalina)
I can run PDl2ork but still can't create the object.

a step by step compiling for dummies would come in handy

I'm not experienced enough to get this running in PD (using PD vanilla or PDl2ork on mac OSX)

I tried (for hours) what's written here, but can't get it to run.
