Abstract
Project CLEA -- CONTEMPORARY LABORATORY EXPERIENCES IN ASTRONOMY -- develops laboratory exercises that illustrate modern astronomical techniques using digital data and color images.
These Labs were developed for Windows, but the authors have bottled them for Silicon Macintosh computers.

Description

Given the evanescent nature of computer applications that work with changing operating systems, we have included three sets of bottles for Silicon Macintosh computers.
As you run any of them, a window will pop up either saying “Please Enter Drive Letter of CD-ROM” or it will be entirely blank except for the “OK” and “Cancel” buttons at the bottom. In either case, simply hit the “Cancel” button and the program will continue to the login screen.
The first set consists of freestanding Macintosh applications within AstrmLab.zip, JupLab.zip, and TransitLab.zip.
Since you did not download these applications from the App Store (we have not yet gotten them installed there), MacOS will give them a "com.apple.Quarantine" attribute that triggers the message: '"AstrmLab.app" is damaged and can't be opened. You should move it to the Trash.' and likewise for JupLab.app, and TransitLab.app.
Click "Cancel" on this message window and open the Terminal application. Therein type:
xattr -d -r com.apple.quarantine
including a space after "quarantine" and then drag the AstrmLab.app onto that line in the Terminal and hit return.
The next time you double click on the AstrmLab.app it will begin with two requests: the first from "Sikarugir" (the program we used to create these bottles) '"Sikarugir" would like access to files in your desktop' and a similar one such as '"AstrmLab" would ..." that you should Allow. But it will not yet run. The third time you double click on the app it will open correctly.
Only the Venus Transit works in the TransitLab.app. The Mercury transit really needs an external CD.
The second set consists of bottles that must be run within the free application Whisky whose creator has indicated that he will no longer actively maintain it.
From the File menu, choose “Import bottle,” and choose the 94AB4990-4D23-4055-9EA8-CCD1117BA4D1 subfolder of the expanded WhiskyPlanets.zip file.
Each time you select AstrmLab within Whisky and click “Run,” an open-window will come up showing the contents of the “drive_c” folder, and you will have to double-click on the “Program Files (x86)” subfolder, the “CLEA” subfolder of that, the “AstrmLab” subfolder of that, and finally on the “CLEA_AST.exe” executable.
To import the JupLab bottle, choose the AF383D20-646E-460D-8FE8-2C1F91F79EB5 subfolder of the expanded Whisky.zip file. For the Transit Lab bottle, choose the 69F73F18-C8BD-4343-87A2-54528B43132D subfolder of the expanded Whisky.zip file.
The third set consists of bottles that must be run within the application CrossOver that requires a fee in excess of $70 after the 14-day trial period. This application is actively maintained as of 2025, so this is the backup plan if the above two versions eventually fail.
From the Bottle menu, choose “Import bottle Archive,” and choose AstrmLab.cxarchive, JupLab.cxarchive, and Transit Lab.cxarchive in turn. Simply double-click on the resulting AstrmLab, JupLab, or Transit Lab to run it.
