Finding the mixxx.log file

Mixxx logs debugging information, MIDI/HID/etc. messages it receives and controller mapping files it loads in the mixxx.log file. When you report a bug or ask for help on the Mixxx forum or IRC channel, please attach your mixxx.log file to help us help you. This is a plain text file that can be read with any text editor.

All Operating Systems (from within Mixxx)

open the Options menu, select Preferences
select Library, scroll to the bottom
click Open Mixxx settings folder
find mixxx.log file

Linux

~/.mixxx/mixxx.log

Note: make sure you have 'Show hidden files' enabled in your file manager in order to show all dot-files and folders.

Windows

%LOCALAPPDATA%\Mixxx\mixxx.log on Vista and up
%USERPROFILE%\Local Settings\Application Data\Mixxx\mixxx.log on XP and below.

You can just type either of those into the Location bar of a Computer or Folder window, or even under Start -> Run... and press Enter.

Note: The file may not show up as mixxx.log unless you've unchecked Hide extensions for known file types in the Windows Explorer folder options. Until then it is just mixxx, the only text file in that location (with a notepad icon.) By default in Windows 7 and up, extensions for known file types are set to hidden. See How to show or hide file name extensions in Windows Explorer.

macOS

~/Library/Containers/org.mixxx.mixxx/Data/Library/Application Support/Mixxx (Mixxx 2.3 and newer)
~/Library/Application Support/Mixxx (Mixxx 2.2 and older)

Note: The user library folder is hidden by default, so use one of the following methods to open the Mixxx folder.
