Ever since Apple issued a diktat that we were to suddenly desist from using Save As on our computers (this is their business ?), and that we should make high-minded efforts to persuade ourselves that we didn't need Save As and should, furthermore, immediately forget how simple and serviceable it had proved for decades, I have made efforts to conceal an inner groan whenever I found myself wasting time, yet again, with the sacerdotal inanities of that pious File > duplicate business.

Brett Terpstra's Restore Save As everywhere article today thus comes like welcome rain …

Let me know if you do ...
