- Download the community server .dmg from the mysql website. Install as usual.
- Download mysql gui tools (if you are too lazy to use the command line stuff) and its a lot like MySQL on windows
- Setting up the service is involved, see here [osxfaq] and this post.
MySQL provides binaries for the great GUI tools for Mac OS 10.4 only, and I had some mysterious crashed when creating/editing tables. Downloading and installing the fixed prefpane [here] seems to have fixed that.
