Not installing on Mac

[ToscaHardy]

I'm not sure if the code is meant to work on a Mac. I'm getting the following on my MacBook Pro with R version 4.2.2. I notice some files called Mac Binaries so maybe it is? I'll try installing on a PC, but I'm just logging this here in case there is a easy Mac fix that I'm missing.
