Native apple silicon macOS m1 and m2 support

Can I install Mojo on macOS m1 or m2 yet?

Not yet, we're working on native support, and you can upvote the GitHub ticket here: https://github.com/modularml/mojo/issues/510 We have instructions to set up a remote x86-64 environment here: https://developer.modular.com/download And if you're on macOS with an x86 chip you can set up a docker container: https://github.com/modularml/mojo/blob/main/examples/docker/Dockerfile.mojosdk

Is it expected not to work even when using a Docker container built with FROM --platform=linux/amd64 mcr.microsoft.com/devcontainers/base:ubuntu-22.04?

titusmoore•15mo ago

I am already running it in the remote x86_64 env, but it is not the same you sure understand. It is good for testing Mojo itself apart from all my real life projects

Jack ClaytonOP•15mo ago

@Julia that's right emulation through QEMU and Rosetta both don't work

titusmoore•15mo ago

Sure I could build API for communication with it, but who does have time for that when I have fulltime job Upvoted

Jack ClaytonOP•15mo ago

Definitely we understand how much the community wants native support!

𝐍𝐚𝐩𝐢𝐞𝐫•15mo ago

When can we expect it for mac

Moosems / Three chickens•15mo ago

Even a month (a named month) estimate would be greatly appreciated imo.

sgaseretto•15mo ago

Even having support for ARM so we could run it with Docker would be great I think

rick•15mo ago

is there a non-native version rn? pardon my misunderstanding but i thought just linux for now?

Jack ClaytonOP•15mo ago

You can install into a remote container if on arm64, or use a docker container if on x86_64

ksandvik•14mo ago

Yes, please keep this Q&A about Mac M1/M2 support, thx.

chadbrewbaker•14mo ago

I finally found some sane documentation on targeting Apple Neural Engine directly. https://github.com/eiln/ane/blob/main/docs/README.md The most simple HelloWorld would be to use the ANE to make a memcopy()? Second would be hashing memory regions?

guidorice•14mo ago

Had to run the curl command twice, the first time it failed with an auth issue. That said, good choice using brew for the macos sdk. Downloading artifacts now... :mojo:

sa-code•14mo ago

Wooooooo

Melody Daniel•14mo ago

Only Apple Silicon? It doesn't support Intel?

Moosems / Three chickens•14mo ago

That’s what I was thinking 😕.

Jack ClaytonOP•14mo ago

@Melody Daniel only Apple Silicon at the moment yeah, you can use docker on Intel Macs for now

Lcross🦠•14mo ago

It's working here on Silicon! Needed to run as lower case modular auth [auth_code] after curl & setting path and before installing mojo

𝐍𝐚𝐩𝐢𝐞𝐫•14mo ago

It is stuck on downloading artifcats

ModularBot•14mo ago

Congrats @𝐍𝐚𝐩𝐢𝐞𝐫, you just advanced to level 3!

aespeiuk•14mo ago

can you give me the exact command? My apple silicon says it is not arm64 tried "curl https://get.modular.com | \ MODULARAUTH=mut \ sh -" and "brew update brew install modularml/packages/modular" and it fails

rdsaylor#2029•14mo ago

Very very disappointed that only Apple silicon is supported! Huge letdown

Lcross🦠•14mo ago

@aespeiuk is it in x86_64?

aespeiuk•14mo ago

mine is apple silicon arm64. but says it is not while trying to install

Lcross🦠•14mo ago

I have just issued the curl command and brew commands were automatic then the export MODULAR_HOME and export PATH commands followed by modular auth [same code as the curl] and modular install mojo

aespeiuk•14mo ago

I'm on zsh brew which is by default on Apple silicon m series

ModularBot•14mo ago

Congrats @aespeiuk, you just advanced to level 1!

Lcross🦠•14mo ago

My brew is 4.1.16 if it helps

aespeiuk•14mo ago

trying to follow this

Lcross🦠•14mo ago

I was on developer.modular.com/download and did the right hand side It's slightly different

aespeiuk•14mo ago

here is the output

aespeiuk•14mo ago

tried manual and the right pane steps and fails

Lcross🦠•14mo ago

I just think you might have brew for x86_64 You can have two brews but I have two condas instead

Jack ClaytonOP•14mo ago

For anyone else hitting above issue saying the arm64 architecture is required but you're on Apple Silicon: On whatever terminal you're using, right click and press Get Info then untick Open using Rosetta:

fishie22•14mo ago

I am getting this error after Installing the Modular CLI modular: error: please run modular auth before attempting to install a package

Jack ClaytonOP•14mo ago

@fishie22 run the command with your auth key after it on: https://developer.modular.com/download

𝐍𝐚𝐩𝐢𝐞𝐫•14mo ago

command not found mojo????

Jack ClaytonOP•14mo ago

Run the steps up the top here: https://docs.modular.com/mojo/manual/get-started/hello-world.html Put it in your ~/.zshrc file

fishie22•14mo ago

I successfully installed the CLI using the auth key. Step 3 raises an error. Maybe a dumb question: do I not need step 3 or do I need the auth key again.

Jack ClaytonOP•14mo ago

run modular auth <your-auth-key-here> first and then run modular install mojo run:

modular auth <your-auth-key-here>
modular install mojo

modular auth <your-auth-key-here>
modular install mojo

haungmickey#000•14mo ago

If you are using ZSH, run the following commands: echo 'export MODULAR_HOME="/{youpath}/.modular"' >> ~/.zshrc echo 'export PATH="/Users/{youpath}/.modular/pkg/packages.modular.com_mojo/bin:$PATH"' >> ~/.zshrc source ~/.zshrc

aespeiuk•14mo ago

is it bash used normally?

guidorice•14mo ago

macos switched to ZSH by default a few releases ago.

ModularBot•14mo ago

@aespeiuk this is unrelated to macOS so I just created a thread here for you: https://discord.com/channels/1087530497313357884/1164597826228076678/1164597826228076678

JackCooperUsesNeovim•14mo ago

When I try to install on my M1 I get this error:

JackCooperUsesNeovim•14mo ago

anyone else have anything similar?

Inspired Labs•14mo ago

On Terminal.app in /Applications, when I right click and press Get Info Open using Rosetta is already unticked. So I have raised an issue on Github.

Alexander van der Werff•14mo ago

Still getting:: modular: The arm64 architecture is required for this software. Error: modular: An unsatisfied requirement failed this build. But Rosetta is turned off

Jack ClaytonOP•14mo ago

Hi @Alexander van der Werff likely due to having intel based homebrew, see the ticket here to fix: https://github.com/modularml/mojo/issues/1078

Alexander van der Werff•14mo ago

Hi Jack, thanks, I was just reading the same on github and was about to try to uninstall and reinstall brew. @Jack Clayton is it required to have the command line tools for Xcode 14.3? I have Xcode 15.0.1. The first step now fails with: Error: Your Command Line Tools are too outdated. I have Xcode 15.0.1 on Ventura 13.6

Zac Bowling•14mo ago

That can happen for a number of reasons but typically if something is in the middle of your connection between the client and server. Like if your network environment has a reverse proxy or some firewall setups or a captive portal for WiFi setups, etc.

JackCooperUsesNeovim•14mo ago

ohhh ok i think ik what it is.

Jack ClaytonOP•14mo ago

@Alexander van der Werff can you try running brew doctor

Alexander van der Werff•14mo ago

Yes did it, I see it prints Warnings: Warning: Your Command Line Tools are too outdated. Update them from Software Update in System Settings. If that doesn't show you any updates, run: sudo rm -rf /Library/Developer/CommandLineTools sudo xcode-select --install Alternatively, manually download them from: https://developer.apple.com/download/all/. You should download the Command Line Tools for Xcode 14.3. Warning: A newer Command Line Tools release is available. Update them from Software Update in System Settings. If that doesn't show you any updates, run: sudo rm -rf /Library/Developer/CommandLineTools sudo xcode-select --install Alternatively, manually download them from: https://developer.apple.com/download/all/. You should download the Command Line Tools for Xcode 14.3. ..and some more, but I should have the Command Line Tools for Xcode 15.0.1 and brew config shows: CLT: 12.0.0.32.27 Xcode: 15.0.1 Rosetta 2: false

Jack ClaytonOP•14mo ago

Oh yeah, I don't even have Xcode installed, maybe try uninstalling it:

CLT: 14.3.1.0.1.1683849156
Xcode: N/A
Rosetta 2: false

CLT: 14.3.1.0.1.1683849156
Xcode: N/A
Rosetta 2: false

You can install everything you need for brew just with:

xcode-select --install

xcode-select --install

And then I just brew install llvm

Alexander van der Werff•14mo ago

Right, I need Xcode though, but I see the CLT is pointing to the wrong version somehow

Jack ClaytonOP•14mo ago

Have you tried uninstalling and reinstalling brew? That seems to be fixing a lot of problems for people

markolonius•14mo ago

Would there be loss of performance if used docker instead of a system (brew) install on an Apple silicon Mac? Not sure if this is the right place to ask.

Alexander van der Werff•14mo ago

yes I did, I had the intel version (because of previous mac), so following https://github.com/modularml/mojo/issues/1078 fixed it partly, now I need to see why brew is pointing to CLT 12.0 while I have xcode 15 installed on my machine.. probably some old left over

Yeison Rodriguez•14mo ago

my vscode extension was not working on mac. However it got fixed when I created a new vscode workspace and reinstalled the extension

Sanchay•14mo ago

still facing this , but the network has no proxy or anything , even connected with my phones hotspot

aespeiuk•14mo ago

It gives all kind of issues like network and so on, where it is actually a different issue. I had a very tough time with the installation as rosetta was enabled in the options for Terminal app inside applications folder. Then I had to delete brew as it was under users and re-did it under opt. Have you tried disabling rosetta?

ModularBot•14mo ago

Congrats @aespeiuk, you just advanced to level 3!

Alexander van der Werff•14mo ago

@Jack Clayton removing the CLT (sudo rm -rf /Library/Developer/CommandLineTools) and xcode-select --install did the trick

Jack ClaytonOP•14mo ago

Awesome thanks heaps for letting me know, glad it’s working for you

Gio•14mo ago

I'm experiencing issues with getting Mojo to recognize the Python library in my Conda environment on my 13" MacBook M2. I have modified the modular.cfg file to include the path relative to the local Python library, as specified in the documentation. However, when I import "sys" from the Mojo REPL, it doesn't seem to read the Python library properly, leading to problems later on. To be precise, the following line in my modular.cfg file defines the location of the Python library within your Conda environment:

python_lib = /Users/gio/opt/anaconda3/envs/pymojo/lib/libpython3.10.dylib

python_lib = /Users/gio/opt/anaconda3/envs/pymojo/lib/libpython3.10.dylib

It appears to be indeed the correct library path within the pymojo Conda environment:

(pymojo) ➜  ~ ls -ll /Users/gio/opt/anaconda3/envs/pymojo/lib/libpython3.10.dylib
-rwxrwxr-x  1 gio  staff  3906684 Oct 22 13:53 /Users/gio/opt/anaconda3/envs/pymojo/lib/libpython3.10.dylib

(pymojo) ➜  ~ ls -ll /Users/gio/opt/anaconda3/envs/pymojo/lib/libpython3.10.dylib
-rwxrwxr-x  1 gio  staff  3906684 Oct 22 13:53 /Users/gio/opt/anaconda3/envs/pymojo/lib/libpython3.10.dylib

Now, when I import the python lib from Mojo's REPL this is the error I get:

2> from python import Python
3> let sys = Python.import_module("sys")
4.
(PythonObject) sys = {
  (PyObjectPtr) py_object = <parent is NULL>
}
Execution interrupted. Enter code to recover and continue.
Enter LLDB commands to investigate (type :help for assistance).

2> from python import Python
3> let sys = Python.import_module("sys")
4.
(PythonObject) sys = {
  (PyObjectPtr) py_object = <parent is NULL>
}
Execution interrupted. Enter code to recover and continue.
Enter LLDB commands to investigate (type :help for assistance).

Do yo have any ideas of what might be the issue? (Interestingly when I installed Numpy on the default Python installation it worked just fine. This issue seems to be related to Conda envs)

hi, I'm completely new to mojo, just installed it on a mac laptop and I'm trying to go through tutorials. Trying to go through the matrix multiplication example but when I try to import numpy I get this:

I'm not fully sure what's the relationship between mojo and my system python, but it seems to be importing numpy from the virtualenv.

rdickert•14mo ago

I'm not fully sure what's the relationship between mojo and my system python, but it seems to be importing numpy from the virtualenv.

I have the same/similar question: Can I choose/activate a particular python env for mojo to work with? I normally do this in my notebooks by selecting a python kernel, but since I need to select Mojo as my kernel, the relationship is no longer clear to me @JRX the solution recommended to me for python import problems (and it did work) was to just install miniconda. Not sure if that applies to your situation, but mojo seems to find python packages after install.

JRX•14mo ago

I guess it makes sense, the trouble is that I already have pyenv installed on my system and it sounds like having both that and miniconda is asking for trouble

rdickert•14mo ago

I agree, I wasn't thrilled to add it, so up to you whether it's worth it. There also seems to be some detail in this post that I just found when I asked #mojo-bot-help - I'm going to give the a read, perhaps it will clear things up

Jack ClaytonOP•14mo ago

@Gio can you try activating your conda environment, then put this in a test.mojo and run it:

from python import Python

def main():
    let sys = Python.import_module("sys")
    print(sys.path)

from python import Python

def main():
    let sys = Python.import_module("sys")
    print(sys.path)

And if you still get an error run:

which -a python
echo $MOJO_PYTHON_LIBRARY

which -a python
echo $MOJO_PYTHON_LIBRARY

JRX•14mo ago

I've tried to set up conda for myself and for python installed with conda mojo works. unfortunately for python from pyenv it doesnt 😢 ok, I managed to solve my problem. the issue comes from the fact that I had system python linked as python_lib in modular.cfg but in runtime I was using libraries from pyenv python. After setting the right python_lib mojo works well with pyenv python. I had to rebuild python with shared libraries though
