If EOS Offline 2.1.0 or earlier was installed on Mac prior installation of Mosaic designer 2, users may encounter an issue where Mosaic Designer will not open or the program will crash upon start up.
Both EOS and Mosaic Designer use an “ETC” folder in the Application Support directory to create sub folders where settings are saved. When the EOS folder was created, it prevented other applications from saving changes to the directory.
In order rectify this is, please follow the step outlined below:
From the Desktop
-Quit EOS Offline
-Click “Go” (Shift + CMD + G)
-Click on “Go To Folder”
-Type in “~/Library”
-Open “Application Support”
-Right click on the ETC Folder and select “Move to Trash”
-Close that Window
Launch Mosaic Designer. Mosaic Designer will recreate the ETC folder with a Mosaic sub folder with all of the proper permissions.
