The Client’s Challenge
A client reached out in a state of understandable frustration. He had invested in a new, powerful M4 Mac Mini, yet his sessions in Logic Pro were plagued by erratic behaviour and sudden crashes. The most baffling symptom? Simply stopping a recording could cause Logic to vanish, throwing him back to the desktop without warning. He’d diligently followed troubleshooting steps, but the instability persisted.
The experience had eroded his confidence not in his ability, but in his tools. He was beginning to suspect his brand-new machine wasn’t powerful enough and was seriously considering a £6,000 upgrade to a Mac Studio to solve the problem. His core challenge wasn’t just a technical glitch; it was a crisis of faith in his studio’s foundation.
Diagnosis: The Digital Crime Scene
When a powerful system behaves erratically on simple tasks, it’s rarely a matter of brute force. It’s a sign of a deeper, more subtle conflict. My investigation began by ruling out the usual suspects. I examined his system remotely, and the initial findings were puzzling:
- System Resources: His M4 Mac was barely breaking a sweat. CPU and memory usage were minimal. This wasn’t a resource issue.
- Disk Performance: He was using an ExFAT-formatted drive. While I typically recommend Apple’s APFS format for optimal performance, the drive showed no errors and wasn’t underperforming. A potential clue, but not the culprit.
- Cloud & Background Processes: No rogue cloud-syncing or background applications were interfering with Logic Pro.
The system was healthy on the surface. The problem had to be deeper. The breakthrough came when the client replicated the crash. This allowed me to access Logic Pro’s crash logs—the digital equivalent of a black box recorder.
The Hidden Culprit: Machine Learning Code
Feeding the cryptic log files into an analytical tool revealed a consistent pattern. The crashes weren’t originating in Logic Pro itself, but were triggered by errors deep within macOS’s own machine learning code. This was the smoking gun. A quick bit of research confirmed our suspicions: other users had reported this precise issue, linking it to a specific bug in the macOS Sequoia 15.2 build. The problem wasn’t the client’s Mac or his software; it was a documented, but hidden, flaw in the operating system he was running.
The Fix: A Two-Step System Realignment
With the root cause identified, the solution was not a hardware replacement, but a precise software update. I advised against drastic measures and prescribed a clear, two-step process to restore stability.
-
1
Update the Operating System
The first and most critical step was to move away from the buggy macOS Sequoia 15.2 build. I instructed the client to update to version 15.7.5. This wasn’t just a random update; this specific version was confirmed to contain the patch that resolved the underlying machine learning bug causing his Logic Pro crashes.

2
Synchronise the DAW Version
Once the OS was stable, the second step was to ensure the best possible harmony between the system and the application. I advised an update to Logic Pro 12. This would ensure he was running the version of Logic most optimised for the updated Sequoia OS and his modern Apple Silicon hardware, closing the loop on any potential software conflicts.
The client performed the updates, and the results were immediate. His system is now running perfectly smoothly, and the erratic crashing has completely disappeared. He was delighted and kindly left us a wonderful review.
Additional Reflections: The £6,000 Fix That Wasn’t Needed
What I find most compelling about this case is the human element. The client was moments away from spending thousands of pounds on a new machine, believing his current one was insufficient. This is a classic example of where expert diagnosis provides value far beyond the session fee.
Ironically, buying a new Mac Studio *would* have solved his problem—but for the wrong reasons. It would have arrived with the latest versions of macOS and Logic Pro pre-installed, thereby incidentally avoiding the bug. It would have been like using a sledgehammer to crack a nut, and a very expensive sledgehammer at that.
My ability to look at his system, see with my own eyes that it was not under strain, and forensically diagnose the true software-based root cause gave him the confidence to trust his existing hardware. That’s the difference between generic tech support and genuine consultancy: we don’t just fix the problem, we provide the clarity and confidence that empowers our clients and saves them from costly, unnecessary diversions.
