is adobe flash player safe to download to my mac

Welcome to Apple Support Communities

If you need Flash for important tasks, download and install it > http://get.adobe.com/flashplayer I do not recommend you to use it due to the number of security issues it has got, but if you need it, you can install it without any problem. Just make sure you keep it updated

If it's not safe for Mac, what are we supposed to do if we try to watch a FaceTime video and it says you have to have flash player to watch it?
