Apple Mail: missing plug-in
I keep getting "missing plug-in" messages from Apple Mail in emails that contain actually JPEGs or other common attachments. I don't know when this exactly started (could be installation of 10.8.3 update or a security update). This "feature" occurs only on my Mac Pro. On my Macbook Pro all works fine with the same configuration.
Faulty system: Mac Pro Early 2008, Mac OS Mountain Lion 10.8.3, latest Apple Mail.
Working system: MacBook Pro 15" Retina Mid 2012, Mac OS Mountain Lion 10.8.3, latest Apple Mail.
I scanned this forum and the usual Google hits for help. I tried the following already:
- repaired permissions, checked disk
- all system & software updates done
- Java preferences "restored to default", Java preferences deleted
- repaired mailboxes
- applied combo 10.8.3 updater
- applied iTunes 10.2 combo installer
- checked all configurations, nothing unusual.
- sent an email with photo attachment via iPhoto
- danced in circles @ midnight & full moon
Nothing worked so far. Any useful idea. This keeps annoying me!
Kind Regards
