Intaglio was a nice drawing application that lost support in 2020 and essentially stopped working when Sonoma came out. Prompted by Golden Gate's warnings that Rosetta is to be removed from the next version of macOS, I was about to delete it. Just for kicks, I tried opening it and it seems to be working just fine on Golden Gate. The only issue I've found is that I have to add an extra page to the range in the 'Print...' dialogue. Otherwise, every drawing I've tried can be opened, edited and printed like it's 2020 again.
So, if you don't have access to Ventura (on a VM or old Mac) but do still have some old '.intaglio' artwork files that you want to convert to SVG / PDF it's worth having go.
