Somehow the database on my local mac (for testing purposes) got corrupted. So I just took the time-machine backup I had and restored the entire «var»-folder with all the databases, tables and logfiles in it.
But now mysql is acting up and throwing all sorts of errors (tables that are not found, ibd-files corrupted and so on).
How do I restore the databases (creating a mysqldump isn't an option, though).
