For some reason people have started having problems with Ollama running in Rosetta on MacOS. Try selecting the Mac app and hitting ⌘I (Get Info...) and checking to see if "Open Using Rosetta" is checked. If it is, uncheck it, quit and relaunch Ollama and try again.

Running it with Rosetta could decrease the performance. Is it really a low-priority issue for you people, it's concerning.

I have checked and found that the Rosetta option was not selected during initialization. After downloading and installing again, I found that it still does not work

FYI, I was experiencing this same error on a Macbook M1 which led me to this issue:

$ ollama run llama2
Illegal instruction: 4

Based on this thread, I looked at the Ollama.app settings and "Open using Rosetta" was unchecked. However, I remembered that when the Macbook M1 first came out, there was some issues with homebrew and/or libraries using the Apple Silicon, and I remember reading about using Rosetta Stone with Homebrew. So I ran the following in my terminal:

$ brew config
...
macOS: 14.3-arm64
Rosetta 2: true

Note the last line. I must've installed homebrew with Rosetta years ago when first receiving the M1 (this might be a clue why several reporting have an M1). So, I went through a painful process of uninstalling/reinstalling (made easier using homebrew-bundle to dump my current homebrew libraries before uninstalling and then reinstall them afterward using brew bundle). I had to reinstall homebrew several times, after each install brew config still showed Rosetta 2: true. Finally after uninstalling homebrew and deleting homebrew Cellar directories I finally installed homebrew without Rosetta.

$ brew config
...
macOS: 14.3-arm64
Rosetta 2: false

After confirming Rosetta 2: false in my homebrew, I then retried the command ollama run llama2 and it worked. 🎉

Thanks for the tip around Rosetta.

One other thought, it's also possible someone has configured their terminal app to run with Rosetta, so I would check that as well if you are having issues.

@dhiltgen commented on GitHub (Jan 26, 2024):

We've recently added CPU variant support for CPUs without vector math extensions (AVX, AVX2, etc.) which as a side-effect, allows Ollama run under rosetta on arm macs. I think we can consider this fixed. If you're still seeing illegal instruction errors on 0.1.22 please re-open.
