macOS High Sierra: APFS Corrupts Disk Images
Back in September, MPG advised to delay adoption of macOS High Sierra for at least six months. The macOS High Sierra rush-job felt disturbing to me. I wrote:
This is the half-baked situation I more or less expected—ship by calendar, not by quality.
A lot of bugs might pop up in APFS, and there might be data loss scenarios if history is any guide.
So I was not at all surprised to read that Mike Bombich, author of the excellent Carbon Copy Cloner, hit upon a data corruption bug in APFS. In macOS may lose data on APFS-formatted disk images, he writes:
This week we reported to Apple a serious flaw in macOS that can lead to data loss when using an APFS-formatted disk image. Until Apple issues a macOS update that resolves this problem, we're dropping support for APFS-formatted disk images.
Is this the last data corruption bug in APFS? One can always hope, but that is highly unlikely.
