iMessage Font trouble
Each time i shut down my computer when i reopen it the font of my iMessage has changed; how can i freeze it once for all please ?
Might be a corrupt .plist.
Do a backup, preferably 2 backups on 2 separate drives.
Quit the application.
In Finder hold down the option/alt key while selecting the Go menu item. Select Library. Then go to Preferences/com.apple.iChat.plist. Move the .plist to your desktop.
Restart the computer, open the application and test. If it works okay, delete the plist from the desktop.
If the application is the same, return the .plist to where you got it from, overwriting the newer one.
If that doesn’t work, repeat the above but delete the com.apple.imagent.plist.
Thanks to Ralph Johns (UK)for some information contained in this.
