Macos Mac Ssd Februarygallagherappleinsider: In macOS 11.4 update Apple has fixed the excessive M1 Mac SSD wear reporting issue noticed in February and confirmed by testers. The final release of macOS 11.4 is available on Monday, July 2nd, 2019 and will automatically address the problem with no user input necessary.
The issue was reported by testers on the forum of Mac Observer sister site, MacIssues.com. They noticed that a software bug in macOS High Sierra 10.13.4 and earlier was causing SSD wear on M1-based Macs to be reported at a constant rate of 15% per day. Based on the known life expectancy of Apple M1 solid-state drives, this would essentially have given most installations less than a year of life with this error present, or about 100TB written before failure. It also caused systems to be reported as “below threshold” for nearly all M1 SSDs in use.
Apple had already fixed the issue in beta versions of macOS 10.13.5 and macOS 10.13.6, but it apparently was not enough to address the issue with final release versions of the operating system, so a software update was released on June 28th that would automatically fix the bug and change how SSD wear is reported in future software updates, including macOS 10.14 Mojave later this year.
MacUsers covered the story of the issue when it was first discovered in February. Apple’s developer beta versions of macOS 10.13.5, 10.13.6, and 10.14 all contained fixes for the excessive M1 SSD reporting problem, but those fixes were not present in the final release of either operating system, leading to speculation that Apple may have been forced to revert back to a previous version of code for some reason before it could ship a final product that had addressed the bug.
