After reinstalling CorelDraw on Macbook I miss Tools/Extras in the menu bar, which is important to me because I can set the scale there.
I also have the same problem with a test version of Corel Draw 2024. Is this due to the Mac version?
In CorelDRAW on Mac, you can find the Options dialog through the "Preferences" entry in the CorelDRAW (main application) menu (see 1st screenshot).
The Document Preferences (incl. the Edit Scale... in Ruler settings) in the Options dialog you can access directly through the Layout menu > Document Preferences... (see 2nd screenshot).
