When I am using my 2015 macbook pro, I cannot see the mouse cursor (i can see the effects of it, though) when connected to a projector using an HDMI cable.
MacBook Pro (Retina, 13-inch,Early 2015), OS X El Capitan (10.11.4)
There are two "classic " ways to connect an external display. One is Mirrored, the other is "Extended desktop" This picture of the Arrange pane shows extended desktop. Each blue rectangle is an Icon for the location of the display on your bench. if you drag them to the same order as they actually appear, or remember that the projector's area is "to the right/up/down/left" of the main display, you can move the mouse freely across the boundary between displays and have it drag items over and track properly.
.
Can I change this setting BEFORE I connect it do the projector? Because as soon as it is connected to the projector, the mouse cursor disappears completely, from both screens. I cannot see it, though it's there and still functions. As in the cursor become invisible, unable to be seen. When it's mirrored, I cannot see the cursor on either the screen of my MacBook Pro or on the mirrored projection screen on the wall.
System Preferences > Accessibility > Display
there is a slider here to make the cursor bigger. In 10.11, there is also a checkbox:
[√] shake Mouse pointer to locate.
If you shake the mouse rapidly side to side, it gets big (like another pointer-shaped thing that comes to mind)👿😮
I had tried all of that, and none of it worked. I have no clue why it wasn't working. I was able to lead the invisible mouse and switch it from Mirrored to separate/extended display, and the cursor reappeared.
