brew

If installing ollama via brew, to expose Ollama on all interfaces (i.e. 0.0.0.0) for use with a remote application, modify the service file to include an OLLAMA_HOST key in the EnvironmentVariables in /opt/homebrew/Cellar/ollama/{version}/homebrew.mxcl.ollama.plist:

<plist version="1.0">
<dict>
	<key>EnvironmentVariables</key>
	<dict>
		<key>OLLAMA_FLASH_ATTENTION</key>
		<string>1</string>
		<key>OLLAMA_KV_CACHE_TYPE</key>
		<string>q8_0</string>
**    <key>OLLAMA_HOST</key>
    <string>0.0.0.0:11434</string>**
	</dict>
  ...

and then restart the service:

brew services restart ollama

launchctl

For launchctl-managed ollama, run the following:

launchctl setenv OLLAMA_HOST 0.0.0.0:11434

and restart your service.
