How to force universal Mac apps to run under Rosetta emulation instead of natively

Apple provides the enhanced Universal 2 binary feature to its developers who wish to ship macOS apps that pack in code for both Intel and Apple Silicon systems. In other words, a universal binary runs natively on both Apple M1 and Intel-based Mac computers because it contains executable code for both architectures. However, certain edge cases may justify running a native Apple Silicon app under Rosetta emulation, and we show you how it's done.

Lack of eGPU support in M1 Macs may only be temporary

Mac with eGPU

As iDownloadBlog reported a few days ago, the new Apple Silicon-powered M1 Macs do not support external GPUs (eGPU), but that could be a temporary hiccup. That's because macOS Big Sur has bee discovered to detect a connected eGPU over Thunderbolt 3, although it's not exposed to the user or actually accessible for compute and graphics tasks.
