Due to new security measures introduced in Catalina (macOS 10.15), many apps including TopSpin don't work the way one might expect, especially when trying to access files on the Desktop and other protected folders.
On my own Mac (running Big Sur), this problem still persists in TopSpin 4.1.3. Furthermore, this can't be solved by changing permissions from inside System Preferences.
This guide will walk you through:
- How to open TopSpin using the macOS Terminal in order to circumvent this issue.
- How to create an app which you can place in the Dock and click on, so that you don't have to open the terminal every time.
