P.S. You must always open AstroImageJ64.app (or a clone on the desktop) to open AIJ properly (after completing one of the above fixes). Opening ij.jar will not open the program properly.

Hi,
I am able to install AstroImageJ in my desktop running Fedora. However, I am facing problem in getting AstroImageJ installed in a MAC laptop. I followed the procedure given in the installation manual. I downloaded the zip file, unzipped it and moved the AstroImageJ
directory to the Applications folder. I opened that folder and moved the AstroImageJ to the dock. Now, when I click AstroImageI image from the dock I get the following message
The application "AstroImage" can't be opened
To overcome this I copied the file "ij.jar" from the area /Applications/AstroImageJ/AstroImageJ.app/ij.jar and put it in the desktop. Now when I click on "ij.jar" I am getting the AsroImageJ toolbar but in the toolbar I get only 12 icons. I am not getting any
icons after Astro-Mode icon,including the Astro-Mode icon. The AstroImage_user_guide mentions that I should get all the icons as mentioned in the user guide. I request help in doing a successful installation in MAC. Thanks in advance.
