I won't do taxes online for security purposes and I won't buy a new computer unless this one breaks. So, next year I plan to switch to HR Block even though I've used TT pretty much since they started on Macs and were known as Mac-in-Tax. Their response is BS since many apps (incl HR Block) will work with older OS's. They just don't want to have to test on multiple OS's. I left Quicken for Mac because of Intuit's lack of Mac support and I will be leaving TT for Mac for the same reason. A stupid corporate decision on their part.
