Previous issues with reporting tools reporting heavy SSD wear in Apple Silicon Macs now appear to be resolved in the latest beta of macOS.
Solid State Drives (SSDs) can only be written a certain number of times before they become unusable, but it takes many years. A series of reports in February 2021 on SSDs in M1 Macs, however, appeared to show that their lifespan was significantly reduced.
At the time, a Appleinsider A source within Apple, not authorized to speak on behalf of the company, told us it was a data reporting error in the tools used to report SSD wear. According to this source, this was not thought to be an actual hardware issue with the SSD, and SSDs don’t age much faster than before due to RAM swapping or other reasons.
Now that same source said Appleinsider that the problem was fixed in the latest beta of macOS. Appleinsider can also now independently confirm that macOS 11.4 beta 2 also reports proper uptime statistics, which was not the case before.
Separately, Twitter users including one of the developers working on the Linux port to Apple Silicon, developer Hector Martin, have now also reported that the issue is resolved.
Update on macOS SSD thrashing issue: It looks like the issue is resolved in 11.4. Do not hesitate to try the betas if you are adventurous, or wait for the final version.
It’ll be interesting to differentiate the source from the XNU kernel once it goes down and see what the bug was …
