I do not know one studio and I want to try. I tried to install SO 2.6 on my mac osx 10.6.8.
KG told me "debugger has-been found running in your system. Please unload it from memory and restart your program." I did not know what to do, I've never seen it .... if someone can give me a solution, thank you for my brain!!

Maybe now it's work as expected

 

A debugger is a piece of software which will monitor another program whilst it's running, used for testing new software. Have you installed any software development package recently?.

 

I have this problem only with the studio one kg, and mean "Please unload it from memory" ..... Thank you for your help. I do not think I installed something with this kind of problem. How to find the debugger to remove it from my HD? ......I'am on mac osx 10.6.8

 

you have something running in the background that the protection script is picking up and preventing you from running the software, first disable any anti virus and try again, check what programs are running in the background and see if you can stop them one at a time and try that, be careful though you may cause your system to crash if you stop the wrong programs, google them first and see what they are and if it safe to temporarily stop them.

 

That sounds bad. - If you did not start a debugging process yourself then your machine might be infected by a trojan or a root kit.
Try Kaspersky mac, to get rid of it. Kasperky might be unable to find & repair the malicious software, though...
