If you are running El Capitan as an operating system, its refusal to authenticate by disc is well known. The only solution for that is to uninstall everything and switch to an Origin for Mac install. If the games are registered to your account, or can be, then there is no additional charge for the digital versions. But the used games will be a problem regardless. Technically, secondhand games will not work through Origin because they cannot be registered to a second owner. There is no viable mechanism to play used TS3 games when registration is required as the sale of such is against EA's terms of usage (sorry).
As for glitches and freezes once you actually get a game launched, many of the newer Mac models have graphics that are not compatible with TS3. It would help to know which Mac model you have, which processor, and which graphics card (all from About This Mac on the Apple Menu). There are some complicated workarounds, but even those don't help every player.
And finally, we are still talking about TS3 for Mac with its built-in 2GB RAM restriction. No Mac can overcome that and it becomes a problem for quite a few players, especially those trying to use many to all of the EPs. :/
