I ran into another weird issue during my first week with my MacBook Pro, for some reason I couldn’t change any of the default apps. Since this is my work laptop I wanted Outlook to be my default email client not Apple’s Mail.
However, it turned out I needed to reset my default app preferences as the preferences file had become corrupt! Use the following command in terminal to do it:
/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -r -all local,system,user
Worked great for me 🙂
