The Out Point Is 1 Frame Ahead in MacOS and not WindowsOS

New switch to MacOS I've become frustrated with this. Not only is this incredibly annoying for exporting projects or selecting the appropriate length clips in the Source Window, using the "selected in/out points". This is a bygone era of film splicing. On Windows software machines the out-point is exactly where the out point is supposed to be, not one frame forward of the scrubber.
Also: If I Set Out Point in my Source window to drag a clip into my timeline, the footage portion of the clip is 1 frame forward of the audio portion,

and disrupts my timeline organization.
This does not happen on Windows machines. I run a KVM and the exact project on my Windows machine produces a different result. If this is a cultural stake in the editing world, can we have a toggle to remove this extraneous frame in the Project Settings -> Timeline submenu for those of us that want to be more efficient?
