Edit: This is a macOS specific issue. A monospace font is used on Linux and windows, but not on macOS. Add to the list of reasons to embed a regular monospace font.
The help output for any RPC command is formatted differently in the macOS GUI console versus a Linux GUI console.
With the Linux GUI console, the type/descriptions for an argument/result are shown at a uniform distance from the argument/result itself, thanks to the use of a monospace font.
With the macOS GUI console, the type/descriptions do not line up because a monospace font is not used. This leads to ‘ugly’ output.
Example: help setwalletflag
