Question

how can i completely delete the message app from my mac?

Answer 1

As per email.
Hi,
In the Finder (have any window open), Use the Go Menu whilst holding down the ALT key.
This will show the Library in the Menu, select this.
Navigate to the Preferences folder.
Find the com.apple.ids.service.com.apple.madrid.plist file and drag it to the Trash.
This is the one Messages reads directly to create the Receive At list and, if shown, the Start Conversations From drop down.
If Messages was starting properly and you restarted it at the point you would have to re-enter the Apple ID.
On the iPhone.
Go to Settings > Messages  and check the app is ON first.
Then check the Send and Receive Section.
This will always list the iPhone Number as ticked and Greyed out (You can’t edit it).
Having said that I have twice found the Number to be Unchecked (whilst still grey out).
If this is the case go to the Apple ID section and Remove the Apple ID.
This will also remove it from the Send and Receive section (you can’t do it the other way round.)
Once that is done, place the iPhone in Airplane mode to break with the Servers.
After a few minutes take it out of Airplane Mode and return to Setting > Messages
You should see the iPhone Number being Verified. Wait until this is done.
(I would normally suggest sending an iMessage to the Apple ID at this point as it would be the only Active ID on the Mac. And sending a reply)
You can now add the Apple ID back to the iPhone if you wish to use that as well, if you intend to use it.
If not then you way want this site https://selfsolve.apple.com/deregister-imessage
Please stick to one method of asking me  (The thread will do for now.)
I am here 3 hours every evening.
I read all the new post regarding email alerts from the boards.
I then filter the Yosemite, Mavericks and iChat Areas using the Contents page and where require Messages or iMessages and deal with unread one.
Posting here at 2.41PM (according to the Time view I have) and then emailing me 11 minutes later seems like you are giving me the hurry up.
In the email and this Post you are not clear if you want Messages to work again.
Removing the com.apple.ichat.plist may help with that.  (The Status Message one will not)
You may find checking the Font Book and the AppleGothic Font  is the answer.
