Suggestions• Backup early & often, and do not re-arrange your file system.
• Don’t try to do a bunch of other things with your system and run Audacity either in recording or in post production modes.
• Mac OS X Intel-based native Audacity is very stable (in the past this was not true).
• If you change your audio settings within your operating system with Audacity running will have random effects. Close Audacity before making major audio setting changes.
• You might want to invest in third party Noise Removal and Compression tools (like RMS).
