Download jemsSEMacOXS.dmg, open the dmg file and copy its content (jemsMacOSX.app) to the Application folder.
During the first startup of jemsMacOSX.app DO NOT PUSH the button "Move to Bin" of the security warning dialogue but instead push
the "Cancel" button and open the System Preferences "Security & Privacy" and push the button "Open Anyway". You will have to provide an administrator login and password to modify the system settings and to allow starting the application (these messages appearances and dialogues depend on the OS version). Finally push the "Open" button.
Note concerning read/write privilege.
Note concerning first execution
Note java VM
In case users of the Mac computer do not have administrator rights it is necessary to change "Sharing & Permissions" of the whole folders
tree and files of directory jemsSEMacOSX in /Applications in order to let
staff (and everyone if necessary) have "Read & Write" privilege.
When jems is excetuted for the first time, all the files are checked for viruses and trojans.
As a result a delay of several seconds should be expected starting jems.
Furthermore the jems .jar files are compiled at this time.
