I recently updated to MAC OS X 10.7.5 on my Mini Mac and since then I cannot open iCal versione 4.0.4. I can't seem to find any other later versions except iCal 155 which I downloaded but it won't install.
The iCal on OSX 10.7.5 should be version 5, not 4.
Is the iCal application in your Applications folder version 5.0.3? (You can check this without opening it by Control-Clicking the iCal application in the Finder and selecting 'Get Info' from the contextual menu.)
Thanks for your reply. I looked in the Applications folder and it says I have version 5.0.3 but when I click on the iCal icon on my desktop it won't open and says that I have version 4.0.4 and that it won't work.
