I have Onyx 2.2.8 with OS X 10.6.8 and every time I update Onyx it says that an error occurred. I then tells me the Onyx site is down or I'm not connected to the internet but I am. What's wrong?
Might be that you've got Onyx in the Utilities folder? I've had the same problem with Onyx- downloading the fresh dmg and installing it over the the previous version has always worked. Let us know if this gets it
