Looks like a simple fix. You can do a simple test:

1. close Pd

2. Right click on the Pd .app & choose "Open package contents"

3. navigate to Contents/Resources/tcl

4. open pd_deken.tcl in a text editor

5. Find the line "for {set i 0} {True} {incr i} {" and change the "True" to "true"

6. save the file

7. run Pd
