I'm here to provide you the information you need in QuickBooks Desktop (QBDT) to Mac.

It's important to note that your annual subscription is uniquely designed for compatibility with QBDT Premier for Windows computers only and cannot be transferred for use on QBDT for Mac due to differences in the software. This is why if you try to register the product on a new MacBook, you will receive an "Invalid number" message.

In addition, if you've used a trial to move your company file or have an existing QBDT for Mac plan and it's nearing expiration, a message will appear indicating "You have 15 more uses left." It is essential to keep track of your usage count, as once it reaches zero, you will be unable to access the program.

Furthermore, QuickBooks Desktop for Mac is no longer offered to new subscribers in the United States. The deadline to purchase a new subscription was September 30, 2024. However, existing users will still be able t to renew their subscription. To know more about these changes, check out this article: Can't buy QuickBooks Desktop as a new US subscriber.

In the meantime, you can continue using your previous computer to get back to work. To ensure that you're company file is up-to-date, you can manually reenter the newly added data or migrate your QBDT Mac file to Windows again.

On the other hand, if wish to access the program in your new machine, consider using cloud hosting services.

Lastly, to help manage your QuickBooks Desktop account and services using Customer Account Maintenance Portal (CAMPs), I recommend reading this article: Manage your QuickBooks Desktop subscriptions and services.
