Thanks for giving us a timetable to plan by. I am sure this is going to create some issues with supporting our students, as any mac shipped after today will have Mt. Lion. Not to attack you, but if you could pass along the word, our organization has been a bit dissapointed with Symantec's long delays in getting new/compatible SEP updates for new operating systems (both Windows and Mac) over the past few years. Many other software vendors we deal with are Apple/Microsoft developer partners and develop their software throughout the beta stages of these new OS's, so that when the retail release arrives, they have a compatible product to offer. We only wish Symantec was working at the same speed (Two of Symantec's biggest competitors have already released Mt. Lion compatible updates for their Enterprise A/V products, but by sticking with Symantec we have to wait a few months). In the past we've even seen your consumer Norton products updated for new OS's before the SEP product. Again, I really appreciate your quick response, this gives us the information we need to plan appropriately. However, please pass along the frustrations expressed by my instution. Symantec has offered us a rock solid and reliable A/V product with world-class protection and excellent customer support for well over a decade, however these long delays in moving our instution forward with OS upgrades due to a lagging Symantec product is honestly enough to persuade us to look at other products (products where such delays are minimal or non-existant).
