TT notified after efile of taxes that I would require Mac OS Big Sur for 2022 TT version. I recently updated to Catalina 10.15. I use:
- MacBook Air 13in. early 2015
- OS Catalina 10.15.7
- Serial # C02S4539H3Q
Need to know if update to BIG Sur possible
- I Use Excel version 16.59 Home & Business 2021.
- Do not use any other MS app
- Use Pages
This not only a product question
What precautions required for successful update.
Thank you
