| Basic Key Commands.
To Open a folder or file, either double click on the item or select it and press Command (or Apple key) + O.
To Close an open Window, either click on the Close box in the upper lefthand corner, or press Command (or Apple key) + W.
To Quit any macintosh application press Command (or Apple key) + Q
To Quit a running process that refuses to die: press Command (or Apple key) + Option + Control + Esc
To Restart a frozen macintosh: press Command (or Apple key) + Control + the Start arrow at the upper right corner of the keyboard.
Holding the shift key down while restarting will allow the machine to start with all extensions off, very helpful if the machine is freezing on startup.
Holding the C key down while restarting will force the machine to boot from a system CD in the CD drive, which would be necessary if the operating system has become damaged. The System CD that came with the machine you have is the best one to use for this.
Restarting while holding down Control + Option + Shift + Delete will force the machine to look for other working system folders further down the SCSI chain. This is handy if you have a problem with internal drives and need to start up from removable media or an external drive.
Control Panels:
Most of the settings available to you in the macOS are accessible via the Apple Menu, in the upper left hand corner of the screen. Click and hold the mouse down on the apple, and you should see an item about halfway down the resulting menu called Control Panels.
Scrolling down to that item, you can let go the mouse while Control Panels is highlighted and the folder window will pop open, so that you can see and access the items inside.
Some changes made to Control Panels are evident immediately, others may require you to restart your machine.
To set and activate any changes you've made, close the Control Panel window.
To make adjustments to the monitor settings or the audio levels, choose Monitors and Sound, and select the item across the top of that window accordingly.
If the monitor is going dark after a period of time, open the Energy Saver control panel and reset the delay before sleep to your preference.
Kiosks: With the Energy Saver Control Panel open, go to the menu item Preferences and choose Server Settings. Make sure both boxes are checked, and close the window to activate them. This will allow the machine to be powered on and off from a remote switch without damaging the operating system.
Rebuilding the Desktop Database
This is a maintenance task that recreates the database that the operating system uses to keep track of all the files on the drive. This is a good thing to do at regular intervals, ie..once a month at least. It can also fix some problems that you may be seeing after prolonged periods of use, and one sign that it is needed is when you notice that the icons visible on the drive revert to a generic document icon.
Restarting while holding down Shift + Command (Apple) + Option keys will force the machine to boot with extensions off and bring up a dialogue box asking if you want to rebuild the desktop file for that machine. After rebuilding the desktop has completed, you should restart the machine normally, and if it generates another rebuild, allow that to complete as well.
Kiosks: Although you could rebuild the desktop using the instructions above, I've included a utility on your kiosk to assist you in doing this task. Within the Utilities folder, you will find a small application called TechTool. Launch this by doubleclicking, you may see some information screens, and then will arrive at a menu screen. Click on the button marked Rebuild Desktop, choose the drive name in the choice window and click OK to the warning screens. The machine will chime to restart, immediately hold down the Shift Key to keep the extensions from loading. When you see Extensions Off on the splash screen, you can let go of that key. The machine will rebuild the desktop and then you can restart normally to return the machine to service.
Kiosks:
Restoring the projector to its intended state:
If for any reason the projector stops working properly, it may be necessary to replace the files from the original program CD.
With the machine running, quit out of the projector. Place the program CD in the CD drawer and close it, an icon of the disk should appear on the desktop.
Double click to open the hard disk icon, and locate the folder containing the projector files. Drag it, and any aliases to it, to the trash.
Select the icon of the CD and drag it over the hard drive icon, you should see a dialogue box indicating that the files are being copied to the hard drive. When copying is completed, select the CD icon again, and drag it to the trash to eject the disc. Go back to the hard drive window, and open the folder you just copied. Choose the file that is called Projector and with it selected, press Command (Apple) + M to make an alias of that file. Drag the alias onto the desktop, to allow easy launching of the projector when you are done.
Making the projector launch on system startup:On the hard disk is a folder called System Folder, if you double click to open that window up and scroll to the bottom, you should see a folder called Startup Items. Open it up by double clicking, and if there is already an alias to the projector inside, drag it to the trash. Drag a copy of the alias you made from the desktop to the Startup Items folder window by holding down the Option key while dragging the alias.
Within that Startup Items folder, there should also be a small file called Empty the Trash. Leave that file alone, it clears temporary items off of the drive whenever the machine is restarted. |
