Aperture 3 Trial.

Hmmm...Does that mean when the 30-day trial of Aperture 3 runs out, you have to stop using the font. or purchase Aperture 3.....

I really doubt the fonts would expire after 30 days, because there is no DRM associated with fonts. Surprising that there is not, considering the top foundries' insane licensing deals and huge prices for freaking fonts, but you can freely copy fonts anywhere you like with no limitations.

BTW, what the hint is implying is to copy the fonts out of Aperture's bundle and install them via Font Book, or dropping them in appropriate Fonts folder.

Thanks,
I poorly wrote that, but I was actually questioning the legality of use of the font, after the trial runs out.
Since the font is incorporated in the app as part of a time limited trial and most likely comes under the same agreements of use as the trial app, I would expect it to be not quite legal to use it after the end of the 30 days.

The trial doesn't delete itself after 30 days. Other proprietary graphical elements still work, such as the icon.

But you're ignoring the obvious: we should be having a whip round to help the designer of this ... "font" ... to afford new glasses.

Nope, their just the files. When you open a font in Font Book, you have the little window which gives you the option to install it.
