Good afternoon, @pvalouch1.
Welcome to the Community. Let's work together to get this resolved as soon as possible.
You can definitely track time on the Mac with QB Time and then pull it into QB Desktop on your PC. Since QB Time is web based it can be open anywhere through a browser.
Here's an additional guide that can help you out: Setup and use QuickBooks Desktop for Windows and QuickBooks Time integration.
If you have any other questions, feel free to ask. The Community is always here to have your back. Take care!
