When you use a group conversation on a MAC message application, you will find that the "recipient" column is filled with the names of the group members, and in some cases it may not be appropriate to display all the names, such as when the group conversation is more informative, you may not be able to tell which group is responsible for what functions, So we can arrange a name or a topic for the group conversation.
If this is a working group, you can mark it "work"; if it's a family chat group, you can mark it as a "family conversation," so choosing a suitable group name will help you distinguish between different groups.
1. First we can open the information on the MAC application, select a group dialog.
2. Click the "Details" button in the upper-right corner.
3. find the "group name" and enter the group name you want to set.
It is worth mentioning that each member in the group can see the new group name, so it is important to choose a suitable name.
