TurboTax CD/Download only works with Windows 8/10 devices. TurboTax Online is compatible with Macs, but unfortunately, we no longer offer TurboTax Online 2017.
The CRA still has the tax forms for 2017 that you can fill out and print. You can find them here: https://www.canada.ca/en/revenue-agency/services/forms-publications/tax-packages-years/archived-gene...
