I am encountering problems syncing iMessages with my Mac. I can send and receive text messages and iMessages on my iPhone. I cannot send and receive iMessages on my Macbook, but I can send and receive text messages on my Macbook.
My Messages app on Mac was working perfectly until I deleted items in my Keychain. I repaired and verified my Keychain afterwards, too. I did do a hard restart and removed all my accounts on my Mac and added them back. I also deleted my iCloud account and re-added it.
I have also disabled iMessages on my iPhone, then re-enabled it. Also de-paired and re-paired my iPhone and Macbook connection for iMessages. I still get the same behavior.
Does anyone have any idea what to do? I have googled and tried everything...
Anytime I send an iMessage through the Messages app, I get the "not delivered!" notice. Is there an error log I can check for iMessages that might give me hints?
