Python runs just fine natively on M1 Macs. The python.org <http://python.org/> installer will install a Universal2 binary (a single binary containing both the i386 and arm architectures).
If you install through brew you get the architecture your brew has been configured for. But there _is_ a problem with native arm Python, and that is that not all extension packages (think: from pypi) have M1 versions available yet. This is especially true for packages that depend on external libraries (which may not have been ported to M1 yet). The way I handle this on my (M1) development machine is that I have both versions of brew installed, which is easy because arm-brew installs into /opt/homebrew by default and intel-brew installs into /usr/local. If I open a Terminal window it has /opt/homebrew/bin before /usr/local/bin in my $PATH, and the background is white. If I open an iTerm window it runs in Rosetta intel emulation mode, it has /usr/local/bin before /opt/homebrew/bin, and the background is a creamy old-fashioned looking off-white color. As long as I do builds in the window of the correct color, and the correct tools I need for building have been installed in the correct directory everything works fine.The white windows will use python3 for arm, the cream windows will use python3 for intel. -- Jack Jansen, <jack.jan...@cwi.nl>, http://www.cwi.nl/~jack If I can't dance I don't want to be part of your revolution -- Emma Goldman > On 12 Jan 2022, at 17:29, Brian Herman <bherman.l...@gmail.com> wrote: > > Do you guys need an M1 mac to test out the latest python? > I have an extra macbook air m1 I would be willing to give people access to it > so they can test the latest python and compile things or I could do it > manually. > My brother said you guys didn't have one yet. > _______________________________________________ > Pythonmac-SIG maillist - Pythonmac-SIG@python.org > https://mail.python.org/mailman/listinfo/pythonmac-sig > unsubscribe: https://mail.python.org/mailman/options/Pythonmac-SIG
