Sage 100

Has anyone tried to install wksetup on a MAC workstation. Client would be on Mas90 v4.4?

Yes but you have to run an emulation software to get Windows running. Parallels or VMWARE are the two that I think are available. I have a client running this no problem. I believe another alternative to present would be to log into the MAS server on something like Citrix or Terminal Server.

Client did mention Parallels.

I believe that this may be supported -- check the virtualization guide in the online area. Otherwise I disclose up front that Sage may not officially support it but customers use it and seem to not have problems -- though it's not guaranteed.
