Get Xcode from the App Store, provided you are happy to get automatic updates.

Rosetta cannot be easily uninstalled once it has been installed, as its files are guarded heavily by the system.ĭo the following before installing CLI Tools, because Xcode (in particular) is large and you will want it downloading in the background. Set everything up without it, as an assurance that you are not accidentally running x86 code, and then only install Rosetta at the end when there are things which are not ready to run without it. Starting out, do not install Rosetta, even if prompted. Rosetta processes will be indicated as Intel. For that, open the Activity Monitor, and sort processes by Kind. Sidebar: How do I tell if Rosetta is running?īefore we get into the weeds, it’s useful to know how to tell if you have Rosetta processes running. Here I’ll cover as much as possible from unboxing your new M1 Mac to getting React Native development going without Rosetta. This is unnecessary (even if running Xcode under Rosetta) and if you follow the instructions below, the pod binary will be arm64 only (as opposed to universal).

Others instruct developers to run pod under Rosetta. Some do not attempt to build for the arm64 simulator, which means the “no Rosetta” guide actually still needs Rosetta. I have read several guides on React Native development without Rosetta, but they all have shortcomings which I hope to address. For iOS development, it’s possible to run Xcode and the terminal in Rosetta, but this will not unlock the full potential of the M1 chip.Īdapptor maintains some native iOS and Android projects, but mostly uses the cross-platform library React Native. The M1’s advantages were apparent out of the box-the UI feels more responsive, the laptop is quieter, and the device emulators fly. I am a strong proponent of RISC architectures, and also keen to adopt new technologies and deprecate old ones. I recently received an M1 Mac from Adapptor because my Intel Mac was struggling in the summer heat. Here I’ll describe the steps I took to set up my dev environment for React Native to make the most of the M1’s promised power, and avoid gotchas with lingering Intel dependencies. Apple has done a fantastic job of making the transition smooth with its Rosetta-2 emulator, but it isn’t perfect. In case you missed it, the M1 is Apple’s own CPU, and while the move to the new architecture won’t be noticed by many users, developers have some work to do.

With just two Intel-based computers remaining in Apple’s stable (Mac mini and Mac Pro), your next Mac purchase will likely be powered by the M1 chip.
