SPIM S20 is a software simulator that runs assembly language programs for the MIPS R2000/R3000 RISC computers. SPIM can read and immediately run files containing assembly language statements. SPIM is a self-contained system for running these programs and contains a debugger and interface to the operating system.

SPIM S20 is a software simulator that runs assembly language programs for the MIPS R2000/R3000 RISC computers. SPIM can read and immediately run files containing assembly language statements. SPIM is a self-contained system for running these programs and contains a debugger and interface to the operating system. SPIM implements almost the entire MIPS assembler-extended instruction set for the R2000/R3000. (I've omitted some the complex floating point comparisons and details of the memory system page tables.) The MIPS architecture has evolved considerably since then (in particular the 64-bit extensions), which means that SPIM will not run programs compiled for recent MIPS or SGI processors.
To install spim, run the following command in macOS terminal (Applications->Utilities->Terminal)
sudo port install spim
To see what files were installed by spim, run:
port contents spim
To later upgrade spim, run:
sudo port selfupdate && sudo port upgrade spim
