Sleeper for Mac

By St. Clair Software $25.00

Developer's Description

Sleeper delivers a host of energy-saving features that now work on nearly every Macintosh, from the Mac Plus to the latest iMacs and G4 PowerMacs. Sleeper provides more options, greater control, and broader hardwarecompatibility than Apple's Energy Saver control panel. This gives older Macs many of the energy saving features of Apple's newer hardware, and provides newer Macintoshes with more extensive and more flexible power management.Users have also reported that Sleeper has helped them overcome problems they've experienced with Apple's Energy Saver control panel. Sleeper's greater configurability, combined with its independence from many of the Mac's built-in power saving functions, allows them to avoid some of the common "insomnia" and "permanent sleep" problems that occur on iMacs and G3/G4 PowerMacs.

Full Specifications

What's new in version 3.5

  • Sleeper now saves multiple configuration settings and will automatically switch between configurations when running a PowerBook from battery or ac adapter. Configurations can also be changed manually from the Control Strip
  • Buttons have been added to allow keyboard entry of any desired delay (1-999 minutes) for the screen saver, disk sleep, password activation, monitor power-down, sleep, and shutdown
  • Sleeper now supports desktop LCD displays, such as the Apple Studio and Apple Cinema displays
  • There are now options to control processor cycling
  • Sleep capabilities in 7450-based G4 PowerMacs (G4/733 and above) are now properly recognized
  • Sleeper now unmounts servers before going to sleep, avoiding Mac OS 9's warning about "losing network services" if the computer is put to sleep
  • On PowerBooks, the Finder's Sleep command is now intercepted by Sleeper, just as it is on desktop Macs
  • The "flash keyboard LED's when attention is required" feature now works with USB keyboards
  • When Sleeper was installed, Disk First Aid would sometimes stop scanning a drive, complaining that the disk was in use. This has been fixed
  • A conflict between Sleeper and Iomega Zip and Jaz drivers has been fixed. The problem could cause the Finder to freeze after waking up from sleep on some Macintoshes
  • The expert options (cmd-option-click on the Help button) now include a switch that prevents Sleeper from changing the backlight brightness of LCD screens
  • Sleep and wake-up are now more reliable on the PowerMac G4 and iMac DV
  • A conflict has been fixed between Sleeper's passwords and Orange PC
  • Sleeper no longer leaves the backlight turned off on PowerBooks if they crash or are restarted while the screen is dimmed
  • Problems waking from sleep under OS 9 have been corrected
  • The clocks on G4 PowerMacs no longer lose time when they're asleep
  • Sleeper now supports ORB drives
  • Sleeper will put machines to sleep even if the monitor is still powered up and undimmed
