Please do not post the same thing multiple times. The board software automatically flags certain posts as needing moderator attention. This happens the most often for new users. I'm pretty sure this is made clear at the time you attempt to post. Posting the same thing over and over again just makes that many more posts the moderators have to weed through later. This makes us sad. Don't make us sad. If your post/thread doesn't appear, just wait a while. Don't post it again. If it hasn't shown up by the next day, then you can try again. I normally go through posts in the mornings, and try to check a few times throughout the day, but I'm not here 24/7. There will typically be a significant delay before posts are approved. Just be patient.

Creating .icns with @2x

I've used img2icns app in the past to create my .icns files but it hasn't been updated. However, the latest Mac App Store requirements in the Application Loader says I need a @2x in my .icns which is 1024x1024. How do I make a .icns to include this?

    You'll need to make a folder with all your icon images, named appropriately, and then use iconutil to convert them. From Apple's documentation on the topic...
    To convert a set of icons to an icns file enter this command into the Terminal window:

    iconutil -c icns [iconset filename]
    where [iconset filename] is the path to the folder containing the set of icons you want to convert to icns.

    The output is written to the same location as the iconset file, unless you specify an output file as shown:

    iconutil -c icns -o [icon filename] [iconset filename]
    You can unwrap an existing ICNS file with...
    iconutil -c iconset [icns filename]
    where [icns filename] is the path to the icns file you want to convert to an iconset.

    The output is written to the same location as the icns file, unless you specify an output file as shown:

    iconutil -c iconset -o [iconset filename] [icns filename]

    I have built a wrapper around these tools which also does the job of scaling your artwork to all the sizes you don't provide.

    It should save some time, so I hope it's worth a couple of dollars!

    Drag your icon (or icons if you want to manually scale the icon for some sizes) to the app and it builds the .icns file for you.

    If you only have a 512x512 icon, then it will scale that up automatically to 1024x1024.
