Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hello KMS6,
You can also open Office Home and a student account on the web browser.
First I suggested you to download the files to MAC.
Once done,
https://www.microsoft.com/microsoft-365/onedrive/download
Sign in with your personal account. That is the account you use for purchasing Home and student 2021.
But you will not get 1TB of storage. You have to buy additional storage plans for the account Home and student 2021.
Once purchased, you can upload the files again to your Personal account. You will only get 5Gb of free storage.
I hope this information helps. If you have any questions, please let me know and I’ll be glad to assist you further.
Best regards,
