Hey @Setiawan and @slh277,

What version of OS X are you running?

Also, just to see, does activating your environment and then running this command:

```bash
CDPATH= R -e 'source("https://bioconductor.org/biocLite.R"); biocLite("dada2")'

```

fix the issue?

We still don't really know what's going on and we're trying to narrow it down. Thanks for your patience!
