RIP for Epson Pro 3880

When I purchased this printer several years ago, it came with an EFI RIP express 4.1 which met my needs. I recently bought a new MAC with OS 10.10. RIP does not function with the new OS. I inquired with EFI several times about the RIP being upgraded for MAC OS 10.10 and as of this post they have not provided an upgrade. Looking for a cost effective RIP which can be used instead of the EFI RIP. Any suggestions? Thanks in advance.
