Check application version in Catalina I just upgraded to Catalina 10.15.7 coming from High Sierra.
On any previous MacOS release I can press space on any app on app drawer to show application version.
I'm positive they removed it in recent release since I can't view app version anymore.
Any other method to view app version?
You can usually see the version number of an Application in the Finder's Preview pane (most obviously seen in Column View, but also available in other views with View &gt; Show Preview).

System Information's Applications panel will also show the Version numbers. (You may need to wait a bit while it collects the info.)

Individual apps can be checked with File &gt; Get Info.
