"Live cannot access the undo history file and is switching to a memory based undo"

  • Live Versions: 9 - 10
  • Operating System: All

In order to resolve this issue, please close Live and then trash the Undo folder (Live 10)/Undo.cfg (Live 9) and the Preferences.cfg file. You will find these files in the following hidden folders:

Windows

\Users\[username]\AppData\Roaming\Ableton\Live x.x.x\Preferences\

Mac

/Users/[username]/Library/Preferences/Ableton/Live x.x.x/

Note: These folders are usually hidden by default. Here's how to access hidden folders.
