"Disc too slow" error message in Logic Pro on your M2 MacBook Air indicates that your storage drive can't keep up with the recording speed. Here are some steps you can take to address this and potentially record at lower I/O buffer sizes:
Optimizing Storage Performance:
Check Storage Space: Ensure you have sufficient free space on your internal SSD. A cluttered drive can impact performance. Aim for at least 10-20GB of free space. Delete unnecessary files or transfer them to an external drive.
Verify Disk Health: Use the built-in "Disk Utility" app to check the health of your SSD. Open "Disk Utility" (search for it using Spotlight) and select your internal drive. Click on "First Aid" and run a verification or repair if necessary.
Optimize Storage (if available on macOS 10.8.1): Some versions of macOS have a "Storage Management" feature that can help optimize storage space. Check "System Preferences > Storage" (if available) and see if there are optimization options you can utilize.
Adjusting Logic Pro Settings:
Increase Buffer Size (Temporarily): While not ideal, try increasing the I/O buffer size in Logic Pro. This gives your disk more breathing room to write data. Go to Logic Pro > Preferences > Audio > I/O. Experiment with slightly larger buffer sizes (like 2048 or 4096) and see if the error persists. Remember, a larger buffer introduces some latency during recording, so find the balance between performance and your recording needs.
Reduce Sample Rate (if necessary): A higher sample rate (like 96kHz) requires the disk to write more data compared to a lower sample rate (like 44.1kHz). If recording high-frequency sounds isn't crucial, consider temporarily lowering the sample rate in Logic Pro to reduce the disk workload. Go to Logic Pro > Preferences > Audio > General. Change the "Sample Rate" to a lower value and test recording again.
Advanced Options (if necessary):
External SSD for Recording: Consider using a high-speed external SSD specifically for recording audio in Logic Pro. This can significantly improve performance compared to relying on your internal storage. Look for external SSDs with fast read/write speeds (e.g., Thunderbolt 3 connections).
Upgrade Internal Storage (if applicable): If your M2 MacBook Air has a user-upgradable SSD, consider upgrading to a larger or faster SSD. However, upgrading internal components might not be feasible for all MacBook Air models.
Additional Tips:
- Check for Logic Pro Updates: Ensure you're running the latest version of Logic Pro (version 10.8.1 as of now). Updates often include bug fixes and performance improvements.
