- In the Finder, click once on the application icon, so it’s highlighted.
- From the File menu, choose Get Info.
- Find the section labelled General and toggle the triangle, if necessary, to open this section.
- On the Kind line, Universal applications appear as “Application (Universal)”.
If your application is Universal but you want it to run with Rosetta, note that there is a checkbox that says “Open using Rosetta”. This can be useful if your Universal application uses plugins that have not yet been released in a Universal format.
