Timestamp

The timestamp is an HTTP query parameter following the Unix Time convention

d = Dirty. If this bit is set, the page is marked as dirty and, therefore, writable
This bit is actually a write-protect bit that software can use to prevent alteration

Warning: Use at your own risk

I assume no responsibility for the use of these instructions, or any negative impact they may have. You probably shouldn't do this. (Unless you really, truly hate vile cruftware like Java.)

Let the games begin

  1. Reboot into Recovery Mode.
  2. Power-on and hold ⌘ + R until Apple Logo appears.
  3. If your hard drive is encrypted:
  4. Start "Restore From Time Machine Backup"
