I exported a correct OTF-data from Glyphs, but some customer got problems with it:
TextEdit (OS X 10.9.5) OR
MSWord2010 (OS X10.8) OR
Pages (5.5.2 2120 + Yosemite) OR
keynote (6.5.3 +Yosemite) OR
=
ERROR: invalidfont OFFENDING COMMAND: definefont— Problem seems to be the Bold weight/instance (which is stylelinked to Regular)
— On OS X 10.10 the Bold weight can be printed without any error.
— Exported the files with Glyphsapp, with uses the AFDKO syntax

Georg Seifert also tried to solve this and did not found a problem — so it could be a problem of that specific printer the customer is using.
