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

Update 3rd November: Following further testing we can confirm that this issue has been fixed. Please download the latest version of the tool to take advantage of this fix (Fixed in

Scheduled network maintenance – October 11th

Our network provider has informed us that they are scheduling network maintenance later this week. Details are as follows:

Scheduled Date and time:
October 11, 2013 at 22:00 (10 PM EDT) through October 12, 2013 at 06:00 (6 AM EDT)

Maintenance Time Frame:
8 Hours from beginning to end

Maintenance Type:
In order to increase the reliability of our network, our Admins will be performing maintenance to our core routers and relocating a majority of of our transit provider fiber.

Estimated Downtime:
We understand the importance of minimizing any downtime associated with maintenance and for this reason we will do everything we can to expedite the process. As it stands now, the maintenance window is 8 hours and while no actual downtime is expected, you may encounter times of increased latency and minor packet loss while routes to our facilities converge. We will have our senior admins on site for this project to avoid any serious issues and we do not foresee any issues lasting longer than the aforementioned maintenance time frame.


If there are any questions or concerns, please feel free to contact us using our support form, which will not be affected.

Kind regards,

Short downtime on Friday 4th October, existing members not affected.

Dear Members,

We experienced a brief moment of downtime on Friday. This happened due to a malfunctioning switch unit in our provider’s infrastructure, which has now been rectified. We have been reassured that the issue is not expected to happen again anytime soon, and that the switch unit will be monitored closely.

EDIT (8th October): The malfunctioning switch unit has now been replaced.

Only the front sites (macgamehacks.com & callofduty4machacks.com) were affected, allowing our existing members to continue using the tool as normal.

If there are any questions or concerns, please feel free to contact us using our support form.

Kind regards,
