OS X Fix: Logitech Control Center Breaks Growl Notifications

Today, I decided to try using my Logitech Elite Keyboard on my MacBook, so I downloaded the Logitech Control Center (link) so that I could map the keys to my preference and ensure that all my keys would work appropriately. I got everything set up easily enough, and my keyboard is working beautifully. However, I noticed that after installing the LCC, my Growl notifications were no longer working. At all. This was frustrating, but I stumbled across a solution via Google searching. What you need to do is remove the following folder:

/Library/InputManagers/LCC Scroll Enhancer Loader

(Source: BrT blog post – Logitech Control Center disables Growl notifications)

Now log out, and log back in. Growl notifications should be working as usual again. There is one caveat that the author from the source above pointed out: custom button mappings for your Logitech mouse or keyboard may no longer work after you do this. However, I have not noticed this problem using my Elite Keyboard and MX500, and a commenter on the blog states that he has not noticed the issue either on an MX Revolution. Basically, your mileage may vary.

It’s worth noting that there is an option that may work for your mouse, should you find that custom button mappings suddenly stop working after doing this. If this is the case, you can try downloading USB Overdrive X (link) and configuring your mouse buttons with that. You can use USB Overdrive X forever for free, but you get a nag screen when you open it and when you start your computer (it lives in your System Preferences). However, if you use it, you enjoy it, and you can afford it, please support the developer!
