Mac Vs. PC

Up until a month ago we were a totally mac program. We run 3 labs with 30 computers each, so 90 computers at onetime are in operation.  Our Techie decided that we could run all software and accounts through the network off the server, which totally bogged down the system.  His solution, change the labs to PC, easy fix. So one of the labs was converted to a PC (Dell) lab, the students and teachers are not happy with the change.  Disclaimer the techie said this was the only solution without costing lots of $$$$, and I believed him, my first mistake.Jump forward, I find out from a mac engineer that the techie could have fixed the problem by making some modifications to how the machines and network worked.  It would have taking a lot of work on the techie’s part.  Bottom line, “Don’t always believe the Techie”, especially one that is leaving soon.We are going to try the configuration changes to one of the labs and see if it works. I will let you all know how it goes.  Oh yeah, as of this moment the techie is still breathing
