552: Notes, clefs, other symbols display incorrectly on Mac OS X.

If you find you can't see the notes, clefs and other symbols in Sibelius on Mac OS X you might want to try the following fixes:

Use the Font Book.

• Run Font Book from your Applications folder
• Select all of the Inkpen2, Opus, Reprise and Helsinki fonts using Command-click
• Right-click and choose Disable Fonts
• When asked to confirm, click Disable
• Now right-click again and choose Enable Fonts
• Now run Sibelius again

If that doesn't work, you can simply delete the Sibelius fonts and reinstall them.

• Quit Sibelius
• In the Finder, go to /Users/username/Library/Fonts and /Library/Fonts
• Drag all the Opus, Inkpen2, Helsinki and Reprise fonts to the Trash
• Empty the Trash
• Now, download and install Scorch, which includes the latest versions of the Sibelius fonts.
• Restart your computer and then start Sibelius

If that doesn't work, it is likely that the system font caches are damaged and need to be recreated.

• Quit Sibelius
• In the Finder, go to /Users/username/Library/Fonts and /Library/Fonts
• Drag all the Opus, Inkpen2, Helsinki (Sibelius 4 & 5) and Reprise (Sibelius 5 only) fonts to the Trash
• Empty the Trash
• Download and install OnyX
• Run OnyX and click Cancel when asked if you want OnyX to check your start-up volume.
• Click the Cleaning button (with an icon representing a broom)
• On the Fonts tab, make sure the System and Users checkbox is switched on, then click Execute
• You'll be told that all applications will be shut down: click Continue
• A progress bar appears as the font caches are cleaned. Once this has completed, click Restart to restart your computer
• Once your computer has rebooted, run Sibelius again, and all your fonts will be back to normal.
