Deleted FaceTime where to get it OSX10.10
My Son deleted FaceTime on the IMAC (iMac (27-inch, Late 2009) 2.8 GHz Intel Core i7, 16 GB 1067 MHz DDR3,
The version in the APP Store won't let me buy, it says my OS is too new. Is there anything I can do to get it?
iMac (27-inch Late 2009), OS X Yosemite (10.10.2)
