I tried both npm and brew.

After installing, in a fresh terminal I run opencode and I get

jeffrey@Jeffreys-MBP ~ % opencode
zsh: illegal hardware instruction  opencode

I have an Apple M3 Max MacBook Pro and installed opencode via npm i -g opencode-ai@latest and it runs without issue.

No. I used npm npm i -g opencode-ai@latest

But I have tried both with the same results.

I just checked claude code and it runs from claude: aliased to /Users/jeffrey/.claude/local/claude

Digging deeper I find that its real path is
/usr/local/lib/node_modules/opencode-ai/bin/opencode

@topdown Did you potentially have https://github.com/opencode-ai/opencode installed from before? It's got the same name, though I couldn't get their tool to work properly 😅 Before trying the Better™ opencode, I made sure to remove that one (brew uninstall opencode-ai/tap/opencode).

FWIW, I use mise and which opencode prints this for me:

/Users/robertkomaromi/.local/share/mise/installs/node/22.16.0/bin/opencode

@topdown commented on GitHub (Jul 7, 2025):

Ok, so I forked it.
Tried to install dependencies, got lame errors, so as a guess I updated bun.
Then the dependencies are installed.

The first startup took forever, to the point I thought it failed to do anything.
It asked me for a provider key, I picked Google, gave it my key

Then it installed Go, and a bunch of Go dependencies.

Finally I see the OpenCode screen. But, init does nothing, I do not see any way to switch providers, and sending a message gives me an error

Typing /editor opened Cursor with a md file at some crazy path

So basically there is nothing I can do with OpenCode, its basically useless on my machine currently.

I was also facing this issue when installing via brew and npm.

Installing the binary directly worked for me. The following steps installed it successfully (Apple m1 max):

curl -LO https://github.com/sst/opencode/releases/download/v0.3.13/opencode-darwin-arm64.zip
unzip opencode-darwin-arm64.zip
chmod +x opencode
sudo mv ./opencode /usr/local/bin/opencode

I was able to resolve the problem by following the instructions here for migrating homebrew from intel to apple architecture.

After updating my path things work as expected. I'm assuming something similar is going on with npm installs.

 ~/ which opencode
/opt/homebrew/bin/opencode
 ~/ opencode auth login

┌  Add credential
│
◆  Select provider
│  ● Anthropic (recommended)
│  ○ GitHub Copilot
│  ○ OpenAI

I have the same issue on intel mac when installing via npm.

% npm i -g opencode-ai@latest 
added 2 packages in 9s
% which opencode
/Users/myname/.nvm/versions/node/v22.17.1/bin/opencode
% opencode
zsh: illegal hardware instruction  opencode

I first thought my environment was bad, but have since installed other things via npm that work as intended.

I also tried downloading the binary and installing it manually as niwoerner suggested but with the same result. I made sure no other opencode was found on the system before installing it and that which found it correctly.

% which opencode
opencode not found

Hi!

I had all those issues, with npm and brew.

I finally decided to remove all the installed versions I had (so npm and brew…) and to use bun install -g opencode-ai.

Now it works well :)

Edit:
Impossible to run it using tmux. Also I get a very very very slow bun installation process for llms setup.

@topdown commented on GitHub (Oct 3, 2025):

For me it was a HomeBrew issue, which the intel version was installed instead of the ARM version for silicon.
I just fixed the HomeBrew installation and OpenCode finally installed and works.

NOTE: this issue affects both installation types, HomeBrew and NPM.

  1. Make sure your NPM and Node are ARM if you are on an Apple Silicon Mac.
  2. Make sure Homebrew is the ARM version.
