Worked: 2.80

Short description of error
Animation Playback caps at 60fps on MacOS when set at 90fps
Same simple animation will hit 90 on Windows. Both OS use to pass this test on 2.80

Exact steps for others to reproduce the error

On MacOS set Playback frame rate to 90fps (Custom)
Animate default cube ex:
Set Cube's Keyframe location for frame one.
Set playhead to frame 1000.
Move cube 1000m on Y axis and Keyframe Location.
Hit Play.

Playback will stay at 60fps

On MacOS we often see graphical issues, but the reported case is apparently not a graphical issue.
Have you checked other OS to make sure the problem is really only on Mac?

Btw, I could not reproduce the problem on Windows.

I tested it in Windows (Bootcamp) and the issue isn’t present.
It only happens in MacOS.
I don’t run Linux so I’m not sure about that OS.

This is because the display on macOS is set to a refresh rate of 60 Hz. Blender syncs to the refresh rate to avoid screen tearing, and to avoid redrawing more often than what the display can actually show.

You may be able to configure macOS to use a higher refresh rate, but it doesn't offer the option for all displays even if the hardware might support it.
