Live is slow to start or hangs on launch
- Live Versions: 8 - 9
- Operating System: All
If Live is very slow to launch, this could be happening for different reasons. In Live 9 such problems could be caused by a huge browser database or problematic plugins. On Mac there an issue which happens in combination with corrupted or incompatible MIDI drivers and causes Live to hang on launch.
The browser database contains location information and meta-data about files and folders of Live's library and packs, as well as content added to Places. If there is a very large amount of files in the folders added to Places, then this could result in a slow launch time.
We recommend that you avoid adding entire drives to Places. Please add discrete folders only, containing Live-readable content (media files, live specific files) to Places. More info here: How to add content to Places.
If Live hangs on the initialise screen, in particular when these messages are presented "Scanning AU Folder" or "Scanning VST folder" then there may be an outdated or problematic plugin preventing Live from launching. Press and hold ALT, then launch Live to bypass plugin scanning. If Live subsequently launches with no issues, then you'll need to update your plugins and remove any that you don't need.
Incompatible MIDI Drivers (Mac Only)
Certain incompatible MIDI drivers can cause Live to to hang on startup and/or take a long time to launch. More information on these issues can be found in these dedicated articles:
