In macOS 11.4 update Apple has fixed the excessive M1 Mac SSD wear reporting issue noticed in February

Context & Ripple Effects
In February, M1 Mac owners reported alarmingly large SSD write counts, with some coverage noting the readings might stem from faulty monitoring tools rather than real wear. Four months later, macOS 11.4 settles the question by fixing what Apple frames as a reporting problem — vindicating the tool-fault explanation without confirming actual hardware damage.
The fix lands one release after Big Sur 11.3's M1-specific optimizations, continuing a familiar Apple pattern seen before with the supplemental update that addressed 2018 MacBook Pro CPU throttling and the backported Meltdown patches: perceived silicon or hardware defects resolved through macOS point updates rather than recalls.
First-order effects
- M1 Mac owners running disk-health monitors see write figures drop to plausible levels once they install 11.4, ending months of ambiguity about whether their drives were genuinely degrading.
- Apple avoids a potential warranty and resale-value controversy by reclassifying the episode as a software bug rather than an SSD defect.
Second-order effects
- Third-party system-monitoring utility developers must recalibrate how they read M1 SSD wear data so their tools match Apple's corrected reporting instead of flagging false alarms.
- Confidence in M1 drive longevity is preserved, which matters for buyers weighing the non-upgradable SSDs in Apple Silicon Macs against Intel-era machines.
Third-order effects
- As Apple moves fully onto its own silicon, hardware-health telemetry becomes part of the macOS update cadence itself — the company now owns both the chip and the diagnostics that judge it, so perception-of-defect crises get patched in software the way the throttling and Meltdown episodes were.
- If the pattern holds, independent monitoring tools become a check on first-party diagnostics, since only cross-tool comparison exposed the discrepancy in the first place.
The trend: With Apple Silicon collapsing the boundary between hardware and OS, macOS point updates are becoming Apple's standard instrument for resolving perceived hardware defects, from throttling to memory-access flaws to SSD wear reporting.
