Mac OS Big Sur & TaxCalc

Article ID: 3120
Last updated: 22 Oct, 2021

On the 22nd October 2021 we updated the installation media for our Mac users. If you are experiencing the problems detailed in the article below please firstly re-download the Mac installer from your TaxCalc account under My Account \ My Products and Services and try the installation again.

If you continue to have problems with installing TaxCalc on a Mac please contact where we will be happy to assist further.

In November 2020 Apple released the Big Sur operating system (v11.0).

If you are running a Mac and have upgraded to Big Sur, for TaxCalc to run as expected you will need to use the following installer file, TaxCalc - v11.11.058 (Autumn 2020) Big Sur release. If you experience a prompt around Apple not being able to check for malicious software please click here.

In some cases we have noted that when TaxCalc opens a return it shows a blank screen for the return itself. In this case please refer to our knowledge base article, How to resolve the white screen issue on my Mac.

Additionally, if you running a Network or Cloud version of TaxCalc it is advisable to ensure TaxCalc is running the latest version before updating your operating system.
