This week, Apple released the new macOS High Sierra with the new file system called APFS (Apple File System). It wasn’t long before I encountered issues with this update. Not a simple issue, but a potential vulnerability. I created a new Encrypted APFS container. And put a password (mypassword) with a hint. After created, I unmounted and mounted again my new container. And voilà. The problem affects only Macs with SSD. I really don’t know how this went unnoticed by Apple (and anyone else). Anyway, it was already reported to Apple by me.
