Is there a definitive set of instructions of how to switch a local install of MongoDB on OSX to use WiredTiger? That is if you install it with just `brew install mongodb`?

Same as with other platforms, you cannot use your existing (mmap) data
directory with WT.

So your choices would be doing mongodump, clearing or rename (and
recreating) directory and reloading data, or configuring a different
data directory path for WiredTiger. You also need to pass
--storageEngine wiredTiger flag if you want to be using wiredTiger.

The mongodump/mongorestore is fine, this is a dev box. In which plist file should I be putting those parameters? What is going to happen on the next upgrade to this?
