Bubble Painter

Apple removed the ability to customize the colors of the message bubbles in Messages.app in Mac OS X 10.10 Yosemite. This app gives you back that ability.

How to install

First download latest version

Then if you're running OS X 10.11 El Capitan or a later version of OS X, you will need to disable System Integrity Protection temporarily in order to use Bubble Painter.

Disable System Integrity Protection temporarily

On OS X 10.11 El Capitan or later versions of OS X, you must disable System Integrity Protection temporarily to use this app.

Note: none of this is necessary on OS X 10.10 Yosemite. Only OS X 10.11 El Capitan or later versions of OS X.

Here's how:

Restart your Mac and hold down ⌘ Command + R until the Apple logo appears on your screen.

You should now see this:

Now open the Utilities menu and select Terminal:

In the Terminal window that opens, enter the following command: csrutil disable

Then press the return key. Afterward you should see the following message:

Then restart your Mac and Bubble Painter should work.

It is recommended that you reenable System Integrity Protection after you're done using Bubble Painter.

To reenable System Integrity Protection, follow the same steps as above, but enter the following terminal command instead: csrutil enable

Then simply reboot again.

It's a known issue that going through this much hassle sucks. If you have an idea for how to avoid all this being necessary, I'd love to hear it!
