imessage is extremely slow since I downloaded Mohave.

Hi imessage is working on my iMac (2015), but it is VERY slow. It used to be almost instant and great. What's up with that and can I do anything about it?

iMac, iOS 10.3.1, 10.11.6, not 10.3.1 (is that all?)

With imessage open, go to

Menu- messages- preferences -iMessages - sign out.


quit iMessage. Relaunch and sign back into iMessage.



I don’t think is age of computer. I have both 2009 and 2013 iMacs ( the latter runs Mojave and imessage is fine and 2009 running High Sierra has no problem With iMessage)
