Hi everyone!!
Yesterday I received my flaming new OAK-D Lite, and after 30 minutes my experience is not that D-Litefull ;-). And I haven't even plugged it in 😅 . I've followed Brandon instructions and copied a Terminal app on the desktop, selected Open using Rosetta, checked that the uname -m was X84_64, and still get the following error (exactly the same I had before re-creating the "Rosetta Terminal"):

Error: Cannot install under Rosetta 2 in ARM default prefix (/opt/homebrew)!
To rerun under ARM use:
arch -arm64 brew install ...
To install under x86_64, install Homebrew into /usr/local.

I have checked that there is a Homebrew folder in /usr/local, but I guess the code is using the native Homebrew installation. Any ideas or suggestions

EDIT:
I have fixed this with:
export PATH=/usr/local/Homebrew/bin:$PATH
in case it helps someone.

If the Terminal is enabled for x86_64 ("Use with Rosetta" box checked" and there is NO previous Homebrew installed in the native arm64 Mac, this may work. The problem I had was that I had apreviously installed Homebrew which goes into /opt/homebrew space and sets "HOMEBREW_PREFIX: /opt/homebrew " and matching "PATH" locations. This apparently confuses the depthai installation scripts which installs another homebrew stack in "/usr/local/homebrew" space but does not completely configure the default paths . Execute "% brew config" to see your default path settings. While I have NOT yet followed these instructions, check out the #macos for posts by whab which uses a virtual environment: https://discord.com/channels/790680891252932659/924798973519216651/934391777811636294 .

This is not the answer.. compile the wheel for the M1 is the solution:

whab — 01/22/2022
For those struggling with running DepthAI natively on their M1 computers, here are step-by-step instructions to build, install and test a M1 native version of DepthAI in less than 30 minutes (tested on a new MacBookPro M1 Pro running macOS Monterey 12.1 with a OAK-D-Lite):

# Install native M1 version of brew
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> ~/.zprofile
eval "$(/opt/homebrew/bin/brew shellenv)"

# Install conda to create virtual environments for Python
brew install --cask miniconda
conda init zsh
Close and re-open a Terminal window

# Install DepthAI by building a M1 wheel (inside ~/DepthAI/)
conda create --name DepthAIEnv39 python=3.9
conda activate DepthAIEnv39
python3 -m pip install -U pip
brew update
brew install cmake libusb
cd ~; mkdir DepthAI; cd DepthAI
git clone --recursive  https://github.com/luxonis/depthai-python.git
cd depthai-python
mkdir build && cd build
cmake ..
cmake --build . --parallel
cd ..
python3 -m pip wheel . -w wheelhouse
pip install wheelhouse/depthai-*

# Test DepthAI with a OAK plugged to your new M1 Mac
cd examples
nano install_requirements.py
    Remove code of block (3 lines) starting with: if thisPlatform == "arm64" and platform.system() == "Darwin":
    Remove code of block (48 lines) starting with: if not args.skip_depthai:
python3 install_requirements.py
python3 ColorCamera/rgb_preview.py

Enjoy!

Hi! Thanks for the code! I'm, new to my M1 mac and macOS and I'm having some problems when I run this part
cmake ..
I get this error

Thanks for writing the install steps. I ran into the following error while running the cmake ..
The depthai-core/CMakeLists.txt and depthai-core/shared directory didn't get created.
Can you suggest a solution? Thank you.

still no further progress in new M1 chips?I mean native.-_-.

    Hello weiYao ,
    M1 runners aren't yet supported by Github, that's why we haven't yet added support for native M1, more info here. As soon as that comes out we will also add support for M1 on depthai.
    Thank you for understanding, Erik

      I am trying to migrate from a working DepthAI/OAK-D on an older (X86-based) MacBook to a new (M1 Max-based) MacBook. Using the standard (and naive, in retrospect) migration approach left me with nothing working, due to several issues, including Python locations and versions, non-functional Homebrew, etc. I think I've got all issues resolved, except for the lack of M1 native DepthAI. Based on this discussion thread and the DepthAI documentation, I seem to have 3 options I can: (1) run the X86 DepthAI using Rosetta; (2) build the M1 native wheels; (3) wait for Luxonis to produce the M1 native wheels.

      My needs are currently not urgent; I'm not wild about Rosetta dependencies; from the thread it seems that with my level of system skills I'd never succeed at building M1 native wheels. That leaves waiting for Luxonis to produce the M1 native wheels. Is there an estimate of when that might happen? Thanks!

      Brandon This sounds exciting! That said, I don't fully understand. The GitHub link appears to suggest that M1-specific (not universal) wheels will get produced; that I think works for me. I'm unsure what you statement "This is not going to be automatically built" means. Does it refer to some Github restriction?

      Assuming the wheels do become available somehow, can you estimate when the relevant documentation will get updated? Thanks.

      • erik replied to this.

          Yes it means that M1 will just install w/out having any other work. Will be equivalent to x86 Mac, or x86 Linux and/or all the standard builds we have now.

          So this should be fully out this week when we do another release with this system.

          Hello gregflurry ,
          We have just implemented building these wheels today. Could you try it out as well?
          python3 -mpip install --extra-index-url https://artifacts.luxonis.com/artifactory/luxonis-python-snapshot-local/ depthai==2.16.0.0.dev0+fc472bd13f9c853148e7a35fc956f4bc0dbf49ae

          Thanks, Erik

              Thank you for bringing support to the M series processors and latest Macs. My camera is sitting beside my new iMac, hopefully the two will be on speaking terms soon.

              • erik replied to this.

                Hernia Please let us know if the above command work for you, so we can release the new M1 wheels to pypi🙂
                Thanks, Erik

                    Successfully installed depthai-2.16.0.0.dev0+fc472bd13f9c853148e7a35fc956f4bc0dbf49ae

                    Did receive this warning:

                    × The package index page being used does not have a proper HTML doctype declaration.
                    ╰─> Problematic URL: https://artifacts.luxonis.com/artifactory/luxonis-python-snapshot-local/depthai/

                    note: This is an issue with the page at the URL mentioned above.
                    hint: You might need to reach out to the owner of that package index, to get this fixed. See https://github.com/pypa/pip/issues/10825 for context.

                    I attempted to install in what should appear to be a system with no DepthAI presence. For other reasons, I already had homebrew installed natively, and had Rosetta installed. I attempted to follow the installation instructions here using a native Terminal. I foolishly ran the command to install dependencies, and then read the paragraph after the command. During execution of the install script, I saw "Running in native arm64 mode, will prefix commands with: arch -x86_64", "Warning: Running in non-interactive mode because $CI is set.", "==> Installation successful!", " >> arch -x86_64 brew install python3 git", "Error: Cannot install under Rosetta 2 in ARM default prefix (/opt/homebrew)!"

                    I'm not sure what this means and how to proceed. All I can tell for sure is that I now have two copies of homebrew, one for arm64 and one for x86_64, plus a git installation, presumably for x86_64. I was unable to extract any useful hints from the link in the installation instructions regarding having a native homebrew. I would like to be able to remove the x86_64 homebrew installation. I don't know what to do about git; I have not checked if an arm64 git exists.

                    Despite my ignorance, I proceeded to attempt install depthAI using pip. That failed with the following:

                    You should consider upgrading via the '/Library/Developer/CommandLineTools/usr/bin/python3 -m pip install --upgrade pip' command.

                    I can see one difference between the two different failed commands; the first was run under Python 3.9 (the 3.9.5 I installed to be compatible with my old system) and the second under 3.8 (the default for Monterey). I see one similarity; both can't find cmake. It was supposed to be installed by homebrew? I can't find it in my system using 'where' or 'type'.

                    Yep, I need help.

                        erik And more flailing .... I realized that I made yet another mistake; I did not execute the proper command from a new Terminal; sigh. When I opened a new terminal and ran the command with Python 3.9, the command succeeded. In the folder /Users/gregflurry/.pyenv/versions/3.9.5/lib/python3.9/site-packages, the command produced the following:

                        So, I think the native wheel(s) did get loaded. I'm now off to clone the repository. Then I'll test in a manual virtual environment, and then in PyCharm.

                          gregflurry Sorry I should have mentioned that these wheels are (AFAIK) only for Python version 3.9 and 3.10 - so the second time it used 3.9 and wheels got downloaded correctly. Let us know if it works as expected, thanks!
