Update to New Apple M1 chip (macOS BigSur)

Hi, I don’t know much about programming and even sound editing, so I can’t give many details.
I am also not sure, if this was already proposed by someone else, in which case I am very sorry.

I recently have a new iMac that runs on the new Apple M1 chip (with the operating system MacOs BigSur) and Audacity is very slow on it unfortunately, for example the line showing where I am on the timeline only moves in little jumps which makes it more annoying to cut single words etc. I use Audacity a lot to cut my weekly podcast.
I read that Audacity is not yet compatible with the new Apple chip. I’d love you someone to update it.

Thanks a lot for having created this easy to use tool :slight_smile:

The jerky movement of the recording/playback cursor is an issue with Macs that have 30-bit displays, which I imagine the latest iMacs have.

With Audacity not running, right-click on the Audacity icon and select Get Info. In the Get Info window, check “Open in Low Resolution”.

Does that help?

oh wow amazing thank you. that works!

For anyone trying to do this on a more recent version of Mac OS X the “Open in Low Resolution” checkbox is gone. You can still get the same effect by manually editing the Info.plist file in the app.

sudo vi /Applications/Audacity.app/Contents/Info.plist

then change




This fixed the laggy UI for me on Monterey on an M1 macbook pro.

Signed up for the sole reason to say thank you to dmertl for posting the answer. I have a MacBook Pro (16-inch, 2021) with an M1 Pro and 32GB of ram. However Audacity was unusable without this change.
