The last edition as ISO 32000-2:2020 was published in December 2020. PDF was standardized as ISO 32000 in 2008.

Apple has now issued a fix: Mac OS X v10.6.7 Supplemental Update for 13” MacBook Air (Late 2010). Update: In last week’s column, I noted another new bug in Mac OS X 10.6.7: iTunes crashing on 13” MacBook Air laptops.

For example, you could switch to a different font (assuming your font choice is not critical) or use Preview instead of Adobe Reader. Until then, the work-arounds are to avoid at least one of the cited requirements for the bug. That’s why I say that many users will never confront this symptom.Īpple will likely fix this glitch in a future update. In general, before you can be affected by this bug, you have to use one of a subset of fonts (OpenType PostScript), work with certain types of files (mainly PDFs), and use specific applications (such as Adobe Reader).

I’m guessing here, but this may be a function of the specific printer. This happened even though the original document was not a PDF, such as when printing from Word or Pages.

Although I could not duplicate this, some readers report that a document can display correctly yet show an “invalidfont error” when printing.

You will see it, however, in Adobe Reader. The TidBITS article noted that it happens only in “applications that rely on Mac OS X’s mechanism for rendering fonts programs like InDesign that have their own rendering engines are immune.” Surprisingly, the problem does not occur in Mac OS X’s own Preview application.

The bug only crops up in certain applications.

The problem primarily occurs with PDF files-especially PDF files you create in Mac OS X 10.6.7, such as via the “Save as PDF…” command in almost any application.

You can find out exactly which of your fonts are OpenType PostScript by launching FontBook and entering OpenType PostScript in the Search box. You are likely to have them, however, if you’ve installed certain third-party software, especially Adobe applications.

As far as I can tell, Mac OS X does not install any such PostScript fonts.

The problem only occurs if you are using OpenType PostScript fonts.
