Owen ParkerIncreasing I/O buffer sample size, maximizing processing threads, and freezing high-CPU synth tracks.
Here is the exact step-by-step diagnostic and remediation procedure verified by Apple Certified Support Professionals:
- Navigate to Logic Pro > Settings > Audio > Devices and set I/O Buffer Size to 512 samples (or 1024 for mixing).
- Set Processing Threads from ‘Automatic’ to the maximum available performance cores.
- Enable Track Freeze on tracks with resource-heavy synthesizers or convolution reverbs.
Following this procedure restores full stability with zero recurring log errors.
