IOhannes,

I'm afraid that "Macintosh OS 10.10 or newer" really means "this is our new-style app, and we are pretty sure that it won't run on older versions of macOS", and the claim of "10.10" is not really tested for :-/

Being familiar with Miller’s precise and forthright writing style, I very much doubt he would go in for such equivocation. Surely he wouldn’t promote untested claims.

could you verify, whether you can still download and open the Pd-0.55-2 package (there's a link for "all software")? if so, could you send us the actual download link you used?

I downloaded from https://msp.ucsd.edu/Software/pd-0.55-2.macos.zip. I can still download and open the package from there.

sorry for causing inconvenience, but I think this is much easier for you to test than for me.

No inconvenience at all. Thanks for your help with this!

Mike Green
