Where does Sequel Pro / MAMP store local databases?
Brian W's answer didn't really help with me using MAMP Pro (v2.1.4), but luckily someone else did. Location for mine were:
/Library/Application Support/appsolute/MAMP PRO/db/mysql
They also said that they've moved it to Dropbox and then used a unix symlink for the original location (not a Mac OS X alias as they don't work), that way it does get backed up as well.
Okay, I figured it out. If you are using MAMP and localhost to create databases, you just need to go to MAMP > db > mysql folder and in there will be all your databases.
Hope that helps anyone who uses Sequel Pro / MAMP / Localhost!
