Long answer:

Open a Terminal, type

cat /Applications/Processing.app/Contents/Info.plist

and you will find, among other

You could try to uncomment the bold line (made bold by me), but there might be a good reason why it was commented (e.g. missing support for 64bit Quicktime).

(Variant: you can also right click on the Processing application and select menu "Show Package Contents").

I had tried that earlier.

Uncommenting the line does nothing; i.e. processing still starts in 32 bit mode.

If I uncomment the line and remove the two below it, then processing does not start at all anymore. (Even though I clearly have 64-bit Java enabled in my Java Preferences panel)

Any other ideas?

Thanks!
