We need more information about your computer like what model you are playing and what version of the Mac OS are you running? Origin has recently had problems with Yosemite and updating to High Sierra has helped them.
You can find the information about your Mac under the black Apple logo in the upper left hand corner. Please do not include your Serial Number.
Version 10.13.6 (macOS High Sierra)
@me1odybae Please also provide your computer's specs, as Tremayne requested. Here's how to find them:
In the meantime, you can try running the Origin reset tool for macs:

It may help to disable Origin in-game as well. Also, as Tremayne mentioned, Origin was not cooperating with OS Yosemite for a few weeks, although the problem has now been addressed. But it might help to uninstall and reinstall Origin after resetting it.
There's no reason you should lose your saved games. They're in your TS4 game folder inside Documents, and you can back up this whole folder, or just the saves, if you want. You can also drag this folder onto your desktop for safekeeping while you try to troubleshoot this issue. In fact, it's worth trying to launch the game after removing your game folder from Documents—if a file within this folder is corrupt, getting it out of the way could let the game load properly. Once you get the game running again, however that happens, you can move your saves and other content into the new folder from the old one and resume gameplay where you left off.
I have now tried to reset and reinstall Origin, but I still have the same problem, after clicking the icon for TS4 I get the message that it is unable to start the game.
This is the full computer specs except for the serial number:
