Late last month, a troubling font issue came to light after Apple rolled out version 10.6.7 of Mac OS X. The update appeared to cause problems with the printing and PDF handling of OpenType PostScript fonts. Apple has not officially acknowledged the problem, but a growing thread on Apple's discussion boards details the issues Mac users are experiencing.
Good news for those affected by this font problem as forum member KJK555 claims to have a fix. KJK555 has released an installation package that replaces the affected 10.6.7 ATS.framework binaries with the previous 10.6.6 versions. The ATS.framework is involved in the font layout and management of Apple Type Services
Before you jump for joy, the initial success rate of this fix is mixed. Some folks claim font issues in apps such as LiveType disappear, while others are still reporting problems with Adobe apps like Acrobat distiller.
If you are plagued by this problem and don't want to wait for Apple to roll out an official update, this solution may be worth a try. As always, proceed at your own risk, as there is always the chance of a negative outcome when you start mucking around with system components, such as fonts and printing. If you do bravely forge ahead and apply the fix, give us a shout in the comments and let us know how it works for you.
