I'm a Mac support professional. But I needed help with a Snow Leopard Mac XServer. Jon was helpful, professional, prompt, and followed through. Plus easy to deal with and pleasant. Because of his extensive prior experience with similar hardware & software, we were able to resolve this issue quickly - far, far more quickly that I would be able to without his help & expertise.
I'm happy and will be a repeat customer.
The problem we resolved today had to do with the problems after changing the IP number of an XServe running Mac OSX 10.6 Snow Leopard. OD becomes uneditible, and you can't add nor change new users in the WorkGroup Manager until this is resolved. Jon knew some unpublished, undocumented commands which fixed the problem. Apparently the only way to get those commands was to wait on hold with Apple support for hours at a time - which he said he did. I'm sure that Apple support is no longer available for an older OSX such as 10.6 (10.11 is current at the time of this writing) so I'm even more grateful that Jon has great notes & is willing to help.
