+### Mac with M1
+Currently Mac offers Rosetta 2 for running code compiled for X86 arcitecture. 
+ We use this to run Gryphon.  Install and run MP Gryphon as follows:
+
+1. Create a command window that is configured to emulate X86, ref. https://dev.to/courier/tips-and-tricks-to-setup-your-apple-m1-for-development-547g:
+
+    * Open Finder.
+    * Click Applications to see applications.
+    * Click the Utilities folder from the list of applications.
+    * right click (Control-click) the Terminal icon and from the pop-up menu, select Duplicate.
+    * Right click the new copy, click Rename, and name it Rosetta Terminal.
+    * Right click Rosetta Terminal, select Get Info.
+    * In the Rosetta Terminal info window, check Open using Rosetta.  Close the Info window.
+    * For easier access to the new Rosetta Terminal, drag it to the bar at the bottom.
+1. Open the new Rosetta Terminal.
+1. Verify that it is emulating x86 instead of arm64 by typing `arch`:
+
+        arch
+
+    It should return `i386` instead of `arm64`.  Although it says i386, it still will not run the 32-bit mode trace-generator.
+
+1. Using the Rosetta Terminal, install MP Gryphon following the instructions for Catalina 10.15 and newer:
+
+        cd ~/Downloads
+        ./install_mp.bash macos_read_only master
+        
+1. Run Gryphon from the Rosetta Terminal:
+
+        cd ~/mp_gryphon/gryphon/python
+        ./mp.py
+
+
