Hi Finavonandy,
I see no one has responded to this post yet. So, at this point I would recommend contacting your local Xerox Support Department to speak with a Product Specialist for more assistance. Please call 1-800-821-2797 or 1-800-835-6100.
To update some of our software we need to upgrade our system on IMac to Big Sur.
We are using Fiery 9eRel2 & Workstation 5.8 which appear not to operate on Big Sur.
Is there a solution apart from replacing the 550 (a low usage machine)?
