SafeSleep... Mac OS X 10.4 improved a little-known feature of Mac OS X; in a low-power situation the contents of memory will be saved to the hard drive and the computer will shut down. On other Operating Systems this is a standard feature known as Hibernation or Suspend-to-disk.
SafeSleep lets you quickly and easily put your laptop into this sleep mode on demand. I have been using it for several months without any problems. But note that this usage of the functionality is not officially supported by Apple.
MACSWEEP It does work. But, once it is used, regular Sleep command from Apple Menu no longer functions for regular Sleep, it only works for hibernation. How do I disable this to get back to regular Sleep? Apparently this is possible, but even though I select regular Sleep from within the application, it still hibernates when I select Sleep from the Apple Menu. (Version 1.0)
MSTIELAU This doesn't appear to work on my 2.66 GHz Mac Pro. Selecting "Safe Sleep Now" causes the machine to go into normal sleep - no difference. (Version 1.0)
