In the control panel, press Option and click on the version number. Watch as its creator’s name is revealed.
Turn Balloon Help on and point to the version number. The balloon will read “Wink, wink”.
 
CloseView (7.2.1)
Use Balloon Help on the CloseView icon. Slightly creative...
This control panel did not return in System 8.
 
Color (7.1)
In the color control panel, click and hold down on “Sample Text” and you will see the name of the person who programmed it, "Dean Yu". Click again and you will see the other creator, "& Vincent Lo". If you click some more, on the 16th click you will see the name Don Louv. It’s hard, but by clicking even more rapidly you will find the words “doodle doodle dee” and “wubba wubba wubba”.
The Color control panel and this easter egg have left us with System 8.0. May they rest in peace.
 
Ô£øControl Strip (1.3)
From: Ed Hajdarpasic (ehajdarp@virtu.sar.usf.edu)
When you Option-click the "Current Hot Key" box below the "Define Hot Key" button, the name "Steve Christensen" appears in the header of the window, replacing "Control Strip."
 
Date and Time (7.5)
Balloon-help on “Daylight Savings Time” to see a common phrase. This egg was obliterated with Sytem 8.
 
Ô£øDesktop Pictures (1.0)
Using CanOpener, I found a very poor computer rendition of a bird, with credits on its body. It can not be found with ResEdit and does not seem accessible through the control panel.
Then, look at ID 4005 in the STR# resource. String number 6 displays:
"This balloon string is no longer needed, so I'll use it to say Hi Mom."

Ô£øEditor Setup (1.2.1)
From: Jory (jory@shoko.calarts.edu)
1. Duplicate the Editor Setup control panel.
2. Rename it to "About OpenDoc..."
3. Open the control panel
4. Choose "About OpenDoc..." from the Apple Menu
You will see a listing of all the people responsible for OpenDoc. According to an Apple engineer, they would have scrolled the list, but there wasn't enough time.
 
Energy Saver (1.1)
From: Patrick Dekker (PDekker@rullf2.MedFac.LeidenUniv.NL)
In the Energy Saver control panel, hold down Option and click on the text "Monitor Energy Saver" at the top of the window. This will bring up a simple credit box. This egg will not work with certain newer versions of the Energy Saver (there seem to be variations out there). This Control Panel comes with the AppleVision software, version 1.5.3.
 
 
Extensions Manager (4.0.1)
Click on the version number (version 3.0.3). In System 8
(version 4.0.1), you want to hold down Option and go to "About
Extensions Manager...". Both ways will reveal credits.
 
Ô£øKeyboard (8.0)
The Apple engineers have finally spiced-up the most boring Control Panel of them all! ...slightly. In System 8, hold down Option when going to "About Keyboard..." in the Apple Menu. You will find a little credit presentation.
 
Labels (7.1)
In the Labels Control Panel, delete all of the names of the Labels. Upon restarting your computer you will find the letters "alanjef" in the Labels menu-bar. This egg was removed to make way for new features in System 8.
Also, show the Launcher at system start-up by setting it in General Controls, and leave the regular labels in the Labels menu. Then, restart your Mac. Once everything on your screen is re-loaded, do nothing. Go up to the Lables menu. There, you will see the text explained above, "alanjef". Going to the Finder will erase it. Any other program that will discourage your computer from going directly to the Finder will have the same effect.
There is also an "m" in the File window. For more info. on that go to "Mood Swings" in the Miscellaneous chapter.
 
Launcher (3.1)
A secret about box is apparent in Launcher when holding down Option and Command keys and click on the background behind the topic buttons (very top buttons on a "raised" surface).
 
Macintosh Easy Open (1.1.1)
Using BBEdit and opening Macintosh Easy Open you will see humorous, abnormal, and hidden message between the encrypted text: “Leave Our Mark On The Tree Weve Been To This Tree Before Preflight Paul”
 
Map (7.5.1)
When holding down Shift, while opening the map control panel, the map will appear magnified.
-Another trick is holding down Option when opening the Map. (200%)
-Holding Shift And Option will magnify to the max. (400%)
-Also when clicking on the version the dialogue “v.7.0, by Mark Davis” will show in the dialogue box. (His initials are also printed in Antarctica)
-If you push Option-Find you can scroll through all the places on the map from A-Z. If you pass Zurich the names of the places will be in the native language they are spoken there.
- Type mid and you will see the middle of nowhere.
In the Map Control Panel of the German System 7.5, if you enter the city names Chicago or San Francisco, you will be shown some very strange places in the world. However, if you have a very detailed map (on paper, not the Control Panel), you will indeed find these places there. San Francisco is shown in the Baleares near Spain, and Chicago is some hundred miles west of Africa. Those places exist, but they have scarcely more than a few hundred inhabitants.
 
Memory (7.5.5)
Turn virtual memory on in the Memory control panel and hold down option while selecting the hard drive to see some interesting credits. This classic was purged with System 8.
 
Monitors (7.5.5)
In monitors, if you click on the version in the upper right hand corner it will show some credits. While clicking, if you hold down Option, the smiley face will change. Different names will appear and will begin to shuffle once you push the Option button repetedly, over 12 times. In early versions of the Monitors control panel, when you click on the version number, only a smiley face pops up. The colors mean that first and last names have made a match.
If Option is held down, in the Control Panel, and the mouse is not, you will see a smiley face inside the computer icon. If you have two monitors, moving the smiley face to the other computer will make it so that the start-up screen is in that monitor.
Ô£øAn engineer wrote me this about the Monitors control panel:
"The Monitors' secret about box, when Dean Yu and I got ahold of it, was simply a bitmap with some names in it. One day Dean and I removed a lot of junk from the project (old useless bits). We had saved so much space, over 15k, that we felt it was ok to put a little bit back in to show that we'd been there. We added "Blue Meanies" as one of the names, the tongue sticking out when you toggled the Option key, and the swapping of first names."
I am sorry to say, but System 8 finally ended this legacy also.
Open Transport Control Panels: TCP/IP (1.2), AppleTalk (1.1), Modem (1.0.1)
From: Brett Helbig ( bhelbig@gorca.com)
In the Open Transport TCP/IP Control Panel, if you choose "About TCP/IP..." from the Apple Menu, a dialog pops up displaying the version number and the copyright info. If you hold down the Option key while selecting "About TCP/IP...", the same dialog pops up with the same info, however, after about 3 seconds or so, the version number and the copyright info disappear. Nothing appears in its place. The dialog just remains empty! The same thing will happen in the AppleTalk and Modem (Open Transport PPP) control panels. However, not the PPP control panel, mentioned below.
 
PC Setup
A lot of thanks to Guido Bertoncini (guido.bertoncini@galactica.it) for this egg.
Note: This control panel is used for the built in Reply 'DOS on Mac' card, containing a DX2/66 processor which is used in Performa 630s and PowerPC 6100/66s DOS Compatibles.
------------
In the PC Setup control panel, click on the version number while holding the Command key. It will then start a 'RP-DOS' session on a mini PC screen. This session is suppose to do some diagnostic tests, show information, and modifies various DOS things. If you want, type help to see what it can do as it is undocumented. However, there is also an egg in the control panel. In short, the egg is simply a list of programmers` in DOS (the reason we bought a Mac in the first place).
Instructions:
cd=change directory (will go to the directory).
dir=catalog directory (will show the directory).
Think of a directory on a PC like a folder on a Mac, but as you
don't have a GUI to see the files, you must type these commands.
1. After entering the "RP-DOS" session, type dir to see the "Software, Hardware, Support and Quality" directories.
2. Then type, for instance, cd hardware to go to the hardware directory.
3. Then type dir, in the next field, next to the word "hardware" to see all of the names of those who developed the software for the Houdini Card.
4. Then type cd and one of the names; lets use the name al_scalise.
5. Type dir again next to "al_scalise" in the next field to see what that person did in that section. In this case it would say "simulations".
6. Type cd to go back to the previous directory.
Balloon Help
While running balloon help, click on the version number while holding down Option to see "This is the System Software Version... nothing more, nothing less." This feature works in version 1.0.7.
Ô£øPPP (1.0.1)
The Open Transport egg explained! Remember that in TCP/IP, AppleTalk, and Modem control panels if you hold down Option and go to about TCP/IP, the copyright dissappears? Apple finally came to its senses with Open Transport PPP and put some credits in the PPP control panel to fill in the empty void. Just hold down Option and go to "About PPP..." in the Apple Menu.
Screen
Hold down Option and click on the upper half of the words "Screen Brightness" to see a credit for Gayle Wiesner. Don't ask me how I found this one.
 
QuickTime Music (2.1d5) Prerelease Development Egg
When I was told about this control panel I had no idea that it was a development release (2.1d5 to be exact). The control panel was intended to work with the MIDI Manager on all new Macs. The point of the control panel is to connect synthesizers and MIDI devices to your Macintosh and play them through QuickTime. The egg works best with the QuickTime Musical Instruments extension, and the main part of the control panel, not the egg, will only work with MIDI Manager. I'm not sure if the control panel will ever be released, or if it ever was. I have not seen it.
The first part of the egg is to go up to the icon in the upper left-hand corner of the window in the control panel. Clicking on it will change the cursor to a musical note. Next you want to hold down Option and click on the icon. Wait a few seconds and you will now see a window with a synthesizer on which you can play a number of things from percussion to harpsicord. It should be pretty fun.
 
Ô£øRemote Access (1.0)
From: bergerdg@aol.com 
Go to the ic18 resource. You should quickly notice I.D. 2010. --->
 
Sound (8.0.5)
In the sounds control panels if you hold down Option and scroll down to sound input or any menu you will hear a sound and see some credits.
Also in the sound control panel under Sound Effects (AV Macs) if you click and hold down on the little version and icon in the lower right-hand corner of the screen, a credit will scroll along the bottom of the screen.
The Sound control panel was also removed in System 8 to make way for better things.
 
Things! (1.0a2)
I somehow got my hands on a really old Control Panel
named Things!, by Gary Woodcock. Its intention is to explain
various QuickTime components and help make the
development of QuickTime products easier. I fiddled with
version 1.0a2 from 1992. At the bottom of the control panel
are buttons to switch to different panels. One panel is an about box. To the right is the QuickTime logo. If you Option-click that logo you will hear a cat meow... kinda, see the picture displayed here, and a read line saying "Phaser says yo, dude!" In the control panel's resource, two Balloon Help strings (which I could not access outside of ResEdit) say:
"Gary is the owner of the phamed and pheared Phaser beast, pictured at right."
and
"Phaser says hi when you click on him."
TV Setup (1.0.1)
From: Brendan Bellina (bbellina@aol.com)
TV Setup will display a box with the authors' names when the version number is clicked.
Ô£øVoices (1.1)
From: Dave11383@aol.com
In the Voices control panel, if you hold Option and click on the version number, the selected voice says "Greetings From Tubian", or something like that.
 
Window Shade (1.3.1)
In Window Shade if you click on the mouse button in the picture you will see some credits by the author. This will not work with version 1.2 or earlier. Window Shade was replaced in System 8.
