How to transfer ICON Software files back into System 6000 MK1



I'm still succesfully using my System 6000 MKI everyday. After much toil, I've figured out how to use the ICON Software App with my Macpro running High Sierra 10.13.6 partition with ICON App 8.4 and on Mountain Lion 10.8.5 partition with ICON App 7.5. I can save presets successfully but I'm having trouble getting them back into the Frame on either partion. Can anyone give me some assistance on transfering the .syx files back into the Frame?
