Same problem here. I purchased TT2025 Home & Business from Amazon, downloaded the software (I think it downloaded) had to also download some other software so it will "work" on a Mac... the only thing I get is a loop to go to Intuit, sign into my account, and then all sorts of other junk from Intuit pops up. Nowhere to type in my serial number for the purchase I just made. I have used TT on a PC for years with no problem. This is extremely frustrating! I feel your pain.
