Unfortunately, TurboTax Desktop is only compatible with Windows products, and we don't support using the software on a Mac. You can use TurboTax Online with Mac OS computers, but the codes for TurboTax Online will not work with TurboTax Desktop & vice-versa.

If you bought TurboTax from a 3rd party retailer and need to request a refund, you can do so on this page: https://turbotax.community.intuit.ca/community/after-you-file-questions/help/how-do-i-get-a-refund-f...

Thanks. I use the software in windows but I had a lot of software issues with windows so my activations have been used up. I’m looking for how to get this reset as I cannot do my taxes now even though I’ve paid for the software. I bought directly only through intuit. Please advise how I can get some resolution on this front. Thank you. 

@linusto TurboTax Desktop allows 3 installations. It looks like you have used all 3 of them. 

They may have been ‘used’ but I’ve had repeated hardware failures and no longer have access to the software. And I can’t file my taxes unless I repurchase another licence. I’ve been using turbotax for years and this is the first time I’ve had this type of issue. But I can’t seem to get the help that I need as a long time loyal user of the software 

@linusto Have you purchased the product directly from Intuit, or it a retail purchase? You can have 3 installations allowed using the same license code.
