- Cause: Several potential culprits exist, from resource limitations to buggy kexts or OpenCore settings. We'll need to narrow them down.
- Basic troubleshooting:
- Reboot: Sometimes, a simple restart clears temporary glitches.
- Logic Pro preferences: Wipe them (Control-Option-Command while launching Logic) and start fresh.
- Resource Monitoring:
- Open Activity Monitor and focus on CPU, RAM, and Disk I/O while using Logic. Identify any spikes coinciding with UI lag.
- CPU: High usage may indicate plugin inefficiency or OpenCore settings like CPUID masking.
- RAM: If Logic uses most of your 32GB, consider adding more or optimizing large audio projects.
- Disk I/O: SSD preferred, HDD bottlenecks lag. Consider optimizing disk performance.
- Plugin Scrutiny:
- Identify resource-hungry plugins by disabling them one by one while monitoring performance. Replace or optimize demanding ones.
- Update plugins to their latest versions, as older versions could have compatibility issues.
- Kext Examination:
- Check for outdated or incompatible kexts: Ensure your kexts are compatible with Sonoma and OpenCore versions. Consider using tools like CoreSlide or Hackintool to identify potential issues.
- Review relevant kexts: Focus on graphics (Radeon kexts), USB (especially for audio interfaces), and any custom kexts related to your specific hardware.
- OpenCore Check-up:
- Review SMBIOS configuration: Ensure your iMac 19,1 SMBIOS matches your hardware specs accurately.
- Check boot args: Review your OpenCore boot arguments for potential conflicts with Sonoma or Logic Pro.
- Reduce Logic UI complexity: Close unnecessary windows and avoid excessive graphics in your project.
- Optimize macOS: Adjust System Preferences like energy saver settings and visual effects to prioritize performance.
- Optimize audio settings: Experiment with sample rate and buffer size in Logic's preferences to find the sweet spot.
- Consider hardware upgrades: More RAM or an SSD can significantly improve performance.

Logic Pro X Slow Choppy UI on Sonoma
Hey folks, was hoping I could maybe get a few tips/pointers on how to fix an issue I'm having with Logic Pro. I just updated to Sonoma on my machine, and Logic ran fine on Monterey, but now on Sonoma I'm getting a lot of lag on JUST Logic Pro.
If I start with a bare bones new project everything runs fine, but as soon as I add a few substantial plugins and tracks, it starts to kind of crawl when interacting with the UI and I'm getting a lot of beachballs. Scrolling while playing is particularly bad.
I tried rebooting and wiping my logic pro prefs, no dice.
Anyone else seeing this issue?
