What is Reddit's opinion of Image2icon?

From 3.5 billion Reddit comments

You can't change that icon (or any live update icon like Calendar) via just the normal copy/paste method as when you click on the app, the icon changes to using an internal icon set which is stored within the app itself. There are a few .icns files that need to be changed. (You can find these files by right clicking the Calendar app, clicking "Show Package Contents" and then navigating the contents of the app.

According to this post here, you need to replace possibly 3 files...

Calendar.app->Contents->Resources->App.icns

Calendar.app->Contents->Resources->App-empty.icns

Calendar.app->Contents->Resources->iCalDockTilePlugIn.docktileplugin->Contents->Resources->App-empty.icns

You'll also need to change the icon via the copy/paste method as well so when the app is not running, it displays the icon you want as well.

I've had to do this for a number of apps which have icons which get updated in real time, such as torrent clients (Transmission).

I use the app img2icns for converting my image files to .icns files. (the free version will convert fine, no need for the paid version)

You need to change the .png file to a .icn file. This means that OSX sees the icon as an actual icon instead of the .png preview icon.

• You can convert it online here: http://convertico.com/
• Or you can download an app to do it here: http://www.img2icnsapp.com/

Edit: Just looked at img2icnsapp in more depth and I would recommend using that because it provides more customisation. :)

Why ask that and wait instead of just converting them yourself? A toddler can figure out how to do that. I'm not gonna share them without OP's permission, so do as I did and just use an app (this one is free: image2icon) or any of the hundreds of online converters (just search png to icns)

Hello everybody! We - at Shiny Frog - just released the 2.0 version of Image2icon.

Image2icon is an icon creation tool which is very popular in the OS X community. Version 2.0 introduces some cool new features such as icon templates, background removal, image tuning, icon restoration and 9 different export options. Image2icon is available on the Mac App Store for free with In-App Purchases.

The 0.1 version of this application was released for the first time 10 years ago and during this timeframe has been downloaded hundreds of thousands times. We built the new version keeping the core features free and adding some new content.

We welcome you to try it and we'll be happy to answer any question. BTW, I strongly suggest to watch the promotional video - I think it's funny :)

I don't have a mac so my knowledge stops here, but it appears you may need a specific icon format for Mac icons.

A quick google search came up with this application.

You might want to download img2icons (the free one works) just drag any image you want to make into an icon and convert to a folder format and then drag them into candybar.
