How can I disable the iMessage pop up when I turn on my Mac? It keeps asking me to sign in with my Apple ID. I don't want to set it up because I don't want to use iMessage. But the box keeps opening every time I turn on my Mac and it is getting frustrating as I have to go through 3 pages before I can turn it off.
I had to contact apple support for this solution. The fact that it is not intuitive implies a usability bug. The reason for the prompt is a keychain entry under either login or local items. Basically after removing all entries with the text 'apple' in them I was able to restart and login with no facetime or imessage prompts to login. I hope this helps.
iMessenger is the iOS version for iPhone/iPad etc. On your Mac, it's called "Messages". Open Messages, go to your Preferences tab in Messages. Select your Message account from the list on the left, then click on the checkbox next to Enable this account to remove the checkmark and disable your Message account on your Mac.
This is not the answer you deserve… but
the answer you need an answer that works…
This did it for me:
- Open Messages and log into it. (Every Mac user does have an Apple account, since it's required to activate the OS on install, no?)
- In the Messages preferences, log out.
Result: no more annoying popup asking me to log in on reboot.
This is about as intuitive as Windows 95 gets, but please don't blame the… messenger.
(FYI, I have no iCloud info set inside of System Preferences, and Settings > General > Handoff & Suggested Apps is ticked off. But these, on their own, were not enough.)
You can disable it through the Preferences in iMessenger app in your Mac. Follow this link
I had the same problem, iMessage kept asking me to sign in every time I logged in on my Macbook. The pop-up mentioned my e-mail address so it must have stored some personal data at one point. However I never signed in to iMessage, iCloud, iTunes or other Apple cloud services on this device or on other Apple devices.
Finally I searched for files that contain the e-mail address and ended up deleting
~/Library/Preferences/com.apple.identityservicesd.plist. YMMV and proceed at your own risk, but it worked for me!
