I just want to know how to fix my current problem. Update2: After looking through imessage on my mac I realized that all the contacts that I cannot send to have usually been sent through text not imessage since their text bubbles are green. These contacts are people who don't have this red highlight on their names and if they do have their name highlighted in red then I cannot send messages to them. Update: After playing around I realized that I can send messages to some of my contacts.

Once your machine reboots, attempt to open iMessage again. Just follow these steps to restart your Mac: 1. It was either delete some files through Keychain Access, restart something or turn on the message forwarding. Though it may seem too simple a fix, often simply rebooting your Mac can solve most glitches including the iMessage not delivered on Mac issue. Going through pages of forums many of the problems were either a year old or older and were very repetitive. About a week ago suddenly I couldn't send any messages without getting the "Not Delivered" and that red exclamation mark. At first iMessage worked for a decent period of time I was getting texts on time and sending them through my Mac just fine. Recently I changed the storage to an SSD and with that change I started to set up iMessage. To include emoji, click the Emoji Picker button. Press Tab or click the message field at the bottom of the window, then type your message. Or click the Add button and choose from your contacts. Type the name, email address, or phone number of one or more recipients. I have an iPhone 5s and a MacBook Pro 13" mid 2012 model with OSX 10.10.4. Click the New Message button at the top of the Messages window.
