sleep trial software / shareware for mac

Sleeper is an energy-saving control panel that will dim your screen, spin down the hard disk(s), and power off Energy Star compliant monitors.
Sleeper can also password-protect your screen and shut down or put your Mac to sleep after a period of inactivity.
Why use Sleeper instead of Energy Saver?
If you have a newer Macintosh, Apple already includes a power-saving control panel called Energy Saver on your system. There are a number of reasons why it makes sense to use Sleeper instead:
- Sleeper works more reliably and consistently than Energy Saver.
- It offers more precise control and numerous customization options.
- Sleeper supports all SCSI and IDE drives, not just those supplied by Apple.
- It provides a screen saver and password protection, which Energy Saver lacks.
Main features:
- Hard disk sleep
- Energy Star monitor support
- Password screen locking
- A very frugal screen saver
- Timed sleep and shutdown
- Configurable hotkey options
- Support for the Sleep command in the Finders Special menu
- Kaleidoscope and Mac OS 9 compatibility
- PowerMac-native support for both IDE and SCSI disks
- Support for multiple IDE and SCSI buses
- Full SCSI Manager 4.3 compliance
- Balloon help.
Enhancements:
- 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 9s warning about "losing network services" if the computer is put to sleep.
- On PowerBooks, the Finders Sleep command is now intercepted by Sleeper, just as it is on desktop Macs.
- The "flash keyboard LEDs 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 Sleepers 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 theyre asleep.
- Sleeper now supports ORB drives.
- Sleeper will put machines to sleep even if the monitor is still powered up and undimmed.

Back in MacOS 8 and 9, Apple had a very useful control panel that protected your mobile Mac from unwanted accesses. For some reasons, Apple did not include this very useful functionality into MacOS X until Panther. If youre still using Jaguar and are concerned about your private data while youre away from your machine, have a look at ScreenLock.

ScreenLock works simple: As soon as your Mac goes to sleep (automatically or when you put it to sleep manually), ScreenLock covers your displays and shows a dialog asking to enter your password, thus preventing access by unauthorized people. Of course the protection can also enabled manually with a hotkey combination.

Inconspicuous
ScreenLock is normally invisible, sitting in the background waiting for the Mac to go to sleep or the hotkey being pressed - and does not consume any processor time. Once the system goes to sleep, the following dialog is shown - until the user enters the correct password.

ScreenLock is shareware and costs $5.

IMPORTANT: ScreenLock conflicts with the password protection of the MacOS screen saver, therefore ScreenLock will change the screen savers preferences to not longer ask for a password when activated.
If you decide not to use ScreenLock, make sure that you re-enable the password check in your system preferences.
