TICKET ARCHIVE -> Ichat Internal Error

rjbush - May 1, 2005 - 3:40 pm

When I try to open an iChat contact, I get this error:

NSInvalidArgumentException:
NSConcreteMutableAttributedString addAttribute:value:range:: nil value

This is a new error, and I am not aware of any changes I made to the system. Please help.

Hi Robert

From Apple on this problem;


If you turn off (disable) the Helvetica font (the Apple-created one) on your computer, you won't be able to start an iChat chat. Instead, you'll see some gibberish message, like this:

iChat Internal Error! NSInvalidArgumentException: NSConcreteMutableAttributedString addAttribute: value: range:: nil value



iChat needs the "Helvetica" font included with Mac OS X to start a chat (you may have other "Helvetica"-type fonts installed with similar names). It's easy to turn the font back on if you used Font Book to turn it off. If you disabled the font using another third-party font management application, use that software to turn it back on, or disable the software.

Let me know if this doesn't help.

That was it. I'm up and running again. Thanks. Robert.
