I’m using an iMac with a 2.5 GHz i5 processor running High Sierra 10.13.2. My audio feed is coming from a Presonus StudioLive 32.4.2AI via S800 FireWire. After applying all the proper system settings to the iMac to ensure proper audio, once I hit record Audacity crashes and closes. Then when I re-open the file is available for recovery, but actually recovering it crashes the program again. Could it be a result of downloading the LAME Encoder for mp3 file export? My church uses this recording method for our sermons, but use mp3 file types to upload to our website for listening. Thanks!
Please help! I am having the same issue on my Macbook Pro 13 inch mid 2012 running 10.12.6 Sierra.
As a test, try rebooting your computer with the Presonus disconnected, and see if you can run Audacity using the iMac’s built in mic and speakers.
