I use Windows but agree with your opinion of TT. WAS a customer since the early 90's when their name was ChipSoft in San Diego. Pulled my hair for three months this year until crunch time and returned it to Amazon. Yes, they took it back after three months. Bought HR Block TaxCut. Clean, intuitive (rather than intuit), reliable, and WORKED with out crashing. Bye, bye, FOREVER TT.
