I use the Mac primarily for Amazon streaming, Vimeo and Youtube. The Oppo player has a Youtube app, but Youtube on blu ray players usually requires the use of a total PITA on screen KB. With the Mac I can use a neat little handheld blutooth remote with a KB built in, shown here. The HDMI output of the Mac goes into the HDMI input of the Oppo to take advantage of its image processing capability and volume control.
