Warning about Mac OS X 10.9 Mavericks compatibility

Dear Members,

Today Apple released the new MAC OS X 10.9 Mavericks system to the public, which unfortunately has affected a number of our users using the advantage tool.

Changes in the new OS are heavily affecting the beta system in the tool, resulting in a game crash as soon as the tool is activated. We have already isolated the source of the issue, but the issue may take some time to fix due to the tool’s architecture.

In the meantime, we strongly advise to refrain from upgrading to the new 10.9 OS X release should you wish to continue using the current tool with the beta system, until we have a permanent solution ready to use.

If you have already upgraded, and downgrading to 10.8 or earlier is not an option, we do have a workaround where the beta system has been disabled (with X-ray vision and no-recoil unavailable). Please contact us if you require the workaround.

We apologise for any inconveniences caused, we are doing our best to resolve this issue as soon as possible, and thank you for your continued support.

Please feel free to contact us should you have any questions.

Kind regards,

The MGH Team
