Of course, this comes with performance penalties of running x86_64 on ARM architecture, but I am not really running anything heavy on the Mac during development anyway, so I’m very happy to eat the performance cost for broader compatibility. Users/bolu/miniconda3/bin/cbc: Mach-O 64-bit executable x86_64 (base) ➜ Tmp file /Users/bolu/miniconda3/bin/cbc What about interpreted languages like Python/Ruby/Bash?įor bash scripts, or interpreted languages like Python / Ruby, you can specify the target architecture by using the arch command like so: arch -x86_64 or arch -arm64 Use lipo tool to create a universal binary, then package shared lib together.Link libraries with executables for both arm64 / x86 as two separate packages.Build static libs / shared libs for both architectures.For a larger app, I imagine the overall steps would be something like: Universal binary apps really contain two executables for both architecture.Īpple provided an example of using lipo tool to wrap both the arm64 and x86 binaries together. The Rosetta2 is smart enough to figure out whether to apply Rosetta2 to translate the binaries. Here’s the interesting bit, on M1 Macs, you can execute these two binraries as if they are native by just invoking them. (base) ➜ Tmp clang++ -arch x86_64 hello.cpp Rosetta is a translation process that allows users to run apps that contain x86_64 instructions on Apple silicon.įirst you need to install Rosetta 2 via the Terminal To quote Apple’s developer documentation on what is Rosetta: After a few weeks of tinkering and exploration, I think it is safe to say that Apple has done an incredible job to ensure smooth transition to the new hardware, and that AMD/Intel/Microsoft or any other hardware manufacturer should be shitting their pants right now for the on-slaught that’s about to come. However, as someone that intends to use the Mac as a development daily driver, my main concern is how my workflow and toolchain will work with the new Apple Silicon and ARM64 instruction set. Recently, I had the priviledge of getting a Macbook Air with M1 chip as as a dev machine to test various things (c++, python, jupyter notebook) that I use.įrom the Youtube reviews ( MKBHD) and various benchmarking websites ( Toms’ Hardware, Daring Fireball), I already know that the performance of the M1 chips is really impressive at the given power consumption and that people are getting ridiculous battery lifes on their M1 Macs. #PYTHON MAC M1 INSTALL PRO#The newest and latest (late-2020) Apple Macbook Air and Macbook Pro 13” with Apple Silicon has been out on the market for a while now. ![]()
