You can connect FaceTime to a whole bunch of people using iOS 12, but it can get tight on a small screen ($ 1,000 at Cricket Wireless) . Your Mac has more room to juggle up to 32 people on a call, and with MacOS Mojave, you can do just that.
; The final version is expected to be released in the fall. As with iOS 12, there are two ways to make a FaceTime call with MacOS Mojave or join a group.
With the FaceTime app itself
Launch the FaceTime app and enter the names, emails, or numbers of the people you want to call in the search field in the upper-left corner. Click the Video or Audio button to make the FaceTime call.
Using the Messages app
If you're in a group text, you can use the endless to-do text messaging and paste everyone into a FaceTime call. Just click the Details button at the top right, and then click the video or phone button to invite everyone in the group message thread to a group FaceTime call. Everyone in your text thread will receive text to join the FaceTime call.
