Unkown embedding model on OS X

Describe the bug I am using the exact same configuration on linux and OS X:

model: claude:claude-3-5-sonnet-20240620
clients:
- type: claude
  api_key: <api-key>
- type: ollama
  api_base: http://localhost:11434
  api_auth: null
  models:
  - name: mxbai-embed-large
    type: embedding

rag_embedding_model: ollama:mxbai-embed-large
rag_chunk_size: 3000 # Specifies the chunk size
rag_chunk_overlap: 150 # Specifies the chunk overlap

# Define document loaders to control how RAG and .file/--file load files of specific formats.
document_loaders:
  # You can add custom loaders using the following syntax:
  #   <file-extension>: <command-to-load-the-file>
  # Note: Use $1 for input file and $2 for output file. If $2 is omitted, use stdout as output.
  pdf: 'pdftotext $1 -'                         # Load .pdf file, see https://poppler.freedesktop.org to set up pdftotext
  docx: 'pandoc --to plain $1'                  # Load .docx file, see https://pandoc.org to set up pandoc
  recursive_url: 'rag-crawler $1 $2'            # Load websites, see https://github.com/sigoden/rag-crawler to set up rag-crawler

On linux if I type .rag on aichat it works and uses the ollama:mxbai-embed-large model, on mac it outputs Unknown embedding model 'ollama:mxbai-embed-large'.

To Reproduce Use the configuration above, pull mxbai-embed-large to ollama, call .rag on aichat.

Expected behavior It works the same way it does on linux.
