Existing users, 
I've had tons of problems since I ran Onyx on my MacBook Pro. In addition to removing foreign languages, it removed my ability to print from any app, my ability to create PDF's and several other quirky problems. My tech people tell me that it was a mistake to use it, and have to reimage my computer.
My advice is -- Don't Use this Utility!!!!!
OnyX
Maintenance, optimization and system personalization tool.
Version: 2.1.1
DON'T USE ONYX!!

DON'T USE ONYX!! - Titanium06
It's totally stupid and impossible!
OnyX don't delete the languages, OnyX don't remove the ability to print or create PDF's...!!
Please, first learn how to use your computer or learn how to knit...
Only one comment... I think that this user is perhaps a developer of shareware competitor jealous of success of OnyX!!
OnyX is and stay free for the good of the community Mac.

DON'T USE ONYX!! - ignatz97
I used this app recently for the first time, and it may be a coincidence, but I lost the ability to print, too. I reinstalled the printer drivers more than once, but I couldn't get the printer to communicate until I reinstalled OSX. Actally, I like what OnyX does, but I'm leery about using it again.Wednesday, May 02 2007 @ 04:07 PM PDT
