This update seems to be broken as hell. What’s worst - the Time Machine is broken so there is no way back if you don’t have full-disk backup (for bit-by-bit backup, check this guide). Other than that, you will get constant kernel panics, you won’t be able to copy files larger than 30 GB if it’s a APFS volume. Also ssh is broken, but to be honest, who uses builtin ssh when we have brew, right?
Until Apple fixes this, STAY AWAY!
