Problem connecting Samsung Galaxy SII to Mac book Pro

I did! I installed Kies and updated drivers from Samsung. It does not help!

It does not help. I did spend week already in google and Apple forums. All these general troubleshooting steps does not work. And issue is defenetely with Mac Pro OSX. As it works with other devices runing the same or other OS. It does not recognize connected phone via USB only un one particupar OS on Mac Pro. Even i can sync it via wireless, but that is not an workaround option as i can`t fully access phone and setting and it`s content so i need to use USB which is not working.

anything else to try ?

Thanks

Connection was working so drivers was ok and then in one day it just did stoped to recognize phone. so abviously it is corrupted. Where is stored all drivers? Might be i can go and manually check to delete all what is related to Samsung because reinstalling software and drivers does not work anymore!

i did went to Samsung Support: here is the result of it:

Isabella: Hi, thank you for contacting Samsung Technical Support. How may I help you today?

Visitor: Hello Isabella. How are you today ?

Isabella: I am fine. Thank you for asking.

Isabella: Please proceed with the query.

Visitor: I hope you can help me fix connecting issue for Galaxy S II with my Mac Book Pro late 2011. It was working till some day and now it does not recognise it when i connect phone via USB. I should note that on Windows on same machine or on my Mini Mac it works fine. so it can't be problem in wire or usb ports. Could not find answer in Apple forums and in forums they did suggest to turn here! I hope you can help me!

Isabella: I understand that you are finding difficulties connecting device to Mac. Am I correct?

Visitor: yes. but only to one specific Mac. as to others it connects without a problem.

Isabella: Thank you for the details.

Visitor: i think problem is in driver only i can't find how to manually remove from Mac

Isabella: May I know the model number of your phone? To know the model number of the phone, please tap on Home>> Applications>> Settings>> About phone.

Visitor: GT-I9100

Isabella: Thank you for the model number.

Isabella: However as you are able to connect the device to windows and Mini Mac then there is no issue with the device. This seems to be an issue with the Mac.

Isabella: However we in Samsung US do not have the instructions on uninstalling drivers on Mac.

Isabella: I request you to contact apple for support related to Mac.

Visitor: Yess it is probably issue with drivers on that particular Mac. Might be you can guide me to location where Kies or phone driver is stored on mac? I then will try to manually delete is from system or replace from another machine

Isabella: The model number you have provided is an international model and we do not have any information on the device you are referring to.

Isabella: I would have surely provided you with the information if we had the information available with us.

Visitor: If you don't know might be you could escalate to some higher level ?

So i was terminated and left without answer. But i did not expect anything else from Samsung Support..

So might be someone of you know where drivers are located? i could try to copy them from one machine to another manualy!!!
