The transition to ARM promises great performance gains while maintaining battery life and I have not been disappointed - everything is extremely snappy and almost instantaneous. What worked was to remove the quarantine attribute that instructs Gatekeeper to prevent the XOP from loading manually using sudo xattr -d ![]() This might might be due tho the Rosetta2 binary translation mechanism or simply a bug in Big Sur. The established workaround (click 'Open Anyway' in System->Security) didn't work for me. Generally, Big Sur will prevent unsigned code from running. XOPs also work, but there are a few hoops to jump through. In my (admittedly cursory) testing I have not encountered any glitches or crashes. The good news first: Igor Pro (8.04, the only version I have tested) works more or less as it used to on Intel machines. I have not seem any reports about Igor on Apple Silicon here so I'd like to share my experience. I have taken the plunge and replaced my oldish MacBook Pro with a shiny new MacBook Pro featuring Apple's new M1 CPU. Wide-Angle Neutron Spin Echo Spectroscopy.
