How can I display the spinning NSProgressIndicator in a different color?

Question

I am using a \"spinner\" NSProgressIndicator in my cocoa app:

I would like to display it in a different color so that it will show up well on a dark backgr

Answer 1

If you’re targeting Mojave or later, you can just set the spinner’s appearance to dark aqua. This will always give you a white spinner, regardless of the user’s system appearance.

spinner.appearance = NSAppearance(named: .darkAqua)

Answer 2

I've seen some third party HUD-style control frameworks that include the bar style NSProgressIndicator, but unfortunately I don't remember ever seeing the spinner. If you can't find a way to get it to do what you want, this page can generate an animated gif that might be helpful for making your own.

This is what I've done:

    #import <QuartzCore/QuartzCore.h>

    ...

    CIFilter *lighten = [CIFilter filterWithName:@"CIColorControls"];
    [lighten setDefaults];
    [lighten setValue:@1 forKey:@"inputBrightness"];
    [self.indicator setContentFilters:[NSArray arrayWithObjects:lighten, nil]];
