Snow Leopard OS X 10.6.7 And OpenType PostScript Font Issues

Update 4/26/11: Apple has released the Snow Leopard Font Update patch that will resolve this troubling issue.
The Snow Leopard Font Update addresses issues displaying and printing certain OpenType fonts and is recommended for all Mac OS X v10.6.7 users.
The update includes fixes that address the following issues:
– Address an issue in which some OpenType fonts don’t display correctly in certain applications
– Resolve issues printing from Preview
– Address an issue with PDF files not opening in third-party PDF viewing applications
– Resolve invalid font errors when printing to PostScript printers

Apple recently released the OS X 10.6.7 update, designed to improve Back to My Mac reliability, resolve SMB connection issues, and address other minor problems. Unfortunately, this update introduced a major problem for designers working with OpenType PostScript fonts, resulting in garbled output and problems creating PDF files.
With no clear and reliable resolution to this issue just yet, MacMedics is still recommending that anyone needing to work with these fonts avoid applying this update. For clients on our Scheduled Service System, your technician will not be applying this update at this time (you may want to remind your users not to manually launch Software Update).
Although unfortunate, this is an excellent example of why we make our recommendations regarding new updates.
Other recently released updates:
iTunes 10.2.2
Safari 5.0.5
Security Update 2011-002 for Snow Leopard*, Leopard, and Leopard Server.
*As this update requires OS X 10.6.7, MacMedics recommends that Snow Leopard users hold off on this update until a resolution for the 10.6.7 font issue is available.
