No Mac and PC are stricly the same ;)

Yep a primitive cylinder is not a box so no points ;)
But with separate you will have points ;)

Shear is another thing
Just draw a line an trim the cylinder (if shear meaning is "cut" ? )

For the cube "Show Points" and you will can move any segments (2 pts) or vertices (x pts) or face (i you select 4 points) ;)
