Site issues in Chrome on Mac

We’ve tested the site in all browsers and for some reason, we are having issues with the Google map section on the homepage, but only in Chrome on a Mac. The developer who created that section of the site does not have a Mac and is unable to test and recreate this problem. Everything looks to be fine, but I can’t seem to find the solution.

The site is here.

Screenshot of the problem is here. The maps should not be overlapping, obviously.

Thanks.
