Mac owners are worrying to update macOS High Sierra. Failing drives in Mac computers immediately after attempting to install new update are getting more and more attention at this time.

Whether the Macs are using HDD or SSD, the drives failure rate is alarming. This is creating a great deal of confusion amongst older Mac owners. Such is not in the reports about the Macs having Retina display. Retina display Macs uses PCIe based blade SSD and these are playing well with High Sierra. Data is a greater concern now.

We are suggesting Mac owners to begin backing up their data as soon as they suspect their Macs are getting slower and slower everyday.

Users mention that drives die permanently or fail to mount immediately after they attempt to update macOS High Sierra 10.13.2. Soon after Apple released 10.13.3 and then 10.13.4 and both of these updates did not acknowledge such issues if any other than minor improvements, security and other patches.

What to do when drives fail after macOS installation or update?

Most importantly we recommend to approach data recovery shop and allow them to secure data at the first place. If data is not a concern, you may opt to install a new drive. We also suggest to install the most stable version of the macOS. We prefer to go for Sierra at this point. Apple reversed HFS+ to APFS which we also suspect is the main culprit of the ongoing issue. macOS High Sierra is tending to be stable but due to its own reverse file format system, it has a long way ahead to mitigate unforeseen issues. Apple did not see its own operating system destroying the drives on which it totally depends to operate. This is unforgivable.
