Hi all!
I have recently upgraded to 10.12.6. Now, for some strange reason, I'm unable to convert any image to ICNS format with Preview app. Previously on OS 10.11.1- 6 it worked fine now all I get is an error: The document “xxxxx” could not be exported as “xxxxx”
Here is a pictorial description:
original image as .PNG
i duplicate
i choose save
as ICNS format
i click save
i get this error...
MacBook, macOS Sierra (10.12.6)
Reread my post. When you open an image (preferably png) with the exact specifications that I provided, then, and only then, will you be able to export to an .icns format. This recommendation is based on practical experience, not speculation.
Right-click on this 300 dpi 512x512 .png image, and save it to your Desktop. Open it in Preview, and then export to .icns.
i can save to every other format except .icns. and no luck changing user permissions I'm afraid 😟
You will need a 512 x 512 minimum .png image, and the higher the resolution the better. I have no problem exporting a 300 dpi 512 x 512 .png to .icns from Preview — on either El Capitan 10.11.6, or macOS Sierra 10.12.6.
Is it all files or just this particular file?
Check permissions on the file. Use Get Info to see permissiona.
Test the file in a new User. Drop in Shared folder for access in a new User.
I've tried all sizes and i can covert to every other format except .icns. i could try a fresh install, it is possible it wasn't a clean update.
