If I wake my Mac from sleep I always get a split second flash of my active desktop before the screen is replaced by my usual password unlock screen. When I unlock, I get my desktop as normal, as it appeared in the split second flash (i.e. It's a live flash, not a cached or buffered screenshot from when it was locked).

I'm not particularly fussed, it's merely annoying, but I imagine that simply filming the screen waking would allow a screenshot to be pulled from behind a locked display, which others may find a risk.

  • does it do that without screen lock ? – Ruskes May 7 '14 at 23:37
  • @Buscar Not sure I understand, without a lock it would just open straight to the desktop anyway? – stuffe May 8 '14 at 6:12
  • you are right (that was a stupid question), my question would be do you see something in the console? – Ruskes May 9 '14 at 19:41
