Hi everyone -- I have an iMac (using Mavericks) and an iPhone 5s. For a while, I was able to switch between devices to read my messages (iMessage). Now, what shows on one will not show on the other. I can't respond on the incorrect device nor can I read messages that were sent to me when they were sent to the other device. I have a single cloud account that both devices use. Mail works fine. Sharing Safari bookmarks is fine. It's just the messages that are causing me trouble. Has anyone else experienced this? What is the best fix so I can access messages on both devices? TIA!
