How do you uninstall MySQL from Mac OS X

Question

I accidentally installed the PowerPC version of MySQL on my Intel Mac in Snow Leopard  and it installed without a problem but of course doesn t run properly  I just didn t pay enough attention  Now when I try to install the correct x86 version it says that it can t install because a newer version is already installed  A Google query led me to perform these actions delete these files to uninstall it   sudo rm  usr local mysql sudo rm -rf  usr local mysql  sudo rm -rf  Library StartupItems MySQLCOM sudo rm -rf  Library PreferencePanes MySQL  rm -rf   Library PreferencePanes MySQL  sudo rm -rf  Library Receipts mysql  sudo rm -rf  Library Receipts MySQL    And finally removed the line MYSQLCOM -YES- from  etc hostconfig  They haven t seemed to help at all  I am still receiving the same message about there being a newer version  I tried installing an even newer version  the current Beta  and it also gave me the same message about a newer version already being installed  I can t uninstall it from the Prefs Pane because I never installed the PrefPane also

Aside from the long list of remove commands in your question  which seems quite comprehensive in my recent experience of exactly this issue  I found mysql sock running in  private var and removed that   I used   find   -name mysql -print 2 gt   dev null     to find anything that looked like a mysql directory or file and removed most of what came up  aside from Perl Python access modules    You may also need to check that the daemon is not still running using Activity Monitor  or at the command line using ps -A    I found that mysqld was still running even after deleting the files

You should also check  var db receipts and remove all entries that contain com mysql    Using sudo rm -rf  var db receipts com mysql   didn t work for me  I had to go into var db receipts and delete each one seperately

You need to identify where MySQL was installed to before attempting to delete it    I always use the Hivelogic guide to installing under Mac OS X which builds MySQL from source  When setting up the build you can specify a directory under which to install MySQL with the --prefix parameter  You should make sure the directory does not exist and attempt to install from source     configure --prefix  usr local mysql --with-extra-charsets complex   --enable-thread-safe-client --enable-local-infile --enable-shared   --with-plugins innobase
