10.8 Mountain Lion Server Upgrade
After upgrading our Mac network to Mountain Lion, our entire network stopped functioning properly. I spoke to Tomotechi and from the conversation I knew these guys were very knowledgeable and capable of fixing our issues. In a matter of hours our Mac server had been reconfigured and everything was working even better than before.
Not only did they do the work, but explained every step they were doing and tutored me on managing the server.
