I recently installed Mac Sierra. I had no alert from Trend Micro to say it was incompatible before installing nor the protection disabled message once installed. I have just seen this message in a screen shot once I opened the message I have been getting which just suggests it might be time to upgrade. My upgrade isn't due until July 18th this year. I had emails offering $50 off each type of antivirus advertised in the message- again I had no reason to think I had lost protection- until Saturday when I received a series of bogus emails. I tried to get help from support but I have to select an operating system and I don't have windows, just Pages on Mac so can't access that support system as a selection is required. I have been very happy with Trend Micro until now. How do I get this protection back and why no alert?
