I see same behavior with Windows and Mac machine.

AFAIK you need to pass execution context first:

import bpy
bpy.ops.wm.open_mainfile('INVOKE_DEFAULT', filepath=r"file.blend", check_existing=True)

Are you really sure this behaves differently on Mac? can you provide details for Mac machine and Blender version used?

Thanks a lot for your reply.

Yes, it is working differently on Mac.

Blender - 3.2.2
Mac - M1 Pro

Yes 'INVOKE_DEFAULT' context shows a "save file" warning, but it also opens up "Blender file view" to open a file instead of opening a file mentioned in filepath argument.

To not show the file selector, you can do the following:

import bpy
bpy.ops.wm.open_mainfile(filepath=r"file.blend", check_existing=True, display_file_selector=False)

@Himanshu-Jain : that should be sufficient, no?

So the final working solution should be,

bpy.ops.wm.open_mainfile('INVOKE_DEFAULT', filepath=r"file.blend", display_file_selector=False)

Thanks @iss & @lichtwerk
