Remote Desktop update shown without having on computer
I have both an iMac and a MBP, neither of which have ever had Remote Desktop installed. I've looked to find it hidden somewhere and haven't found it anywhere. However, both computers show an available update for Remote Desktop. Remote Desktop Client Update 3.8.4. As I've never downloaded this program, why does it show up as an update and how do I delete it from the list of updates without downloading it? Thanks.
