Customising the Citrix Receiver for Mac OS
Here’s a fun little customisation if you grow tired of the green bubbles of gloom.

The background above is a png file, with the following dimensions:
- Height: 2048
- Width: 1056
So if you want to replace this file, go find your replacement picture and ensure your picture is of a similar enough size.
Once you have a png file with similar enough dimensions, open the finder application, open the applications folder and right click the Citrix Receiver app, choose “Show Package Contents”.
Browse down to: contents > resources

In this folder, you will find a file “backgroundImage_big_b.png”, before you start, rename this file to back it up.
Now simply copy your replacement file into this folder, using the above name:

And that’s it! You’ve now got a lovely custom Citrix Receiver:

PS: I wouldn’t try to do this with windows, the file is an embedded resource and would require resource hacker to change the file.

Height size is 1536 not 1056.
