How do I move QuickBooks from iPhone to mac?

Hi Three Step Concrete Coatings,

Welcome to the Community! Being able to transition from a phone to a computer gives you flexibility in the running of your business. QuickBooks Online stores all your data in the cloud so you can easily access your books and pick up from where you left from any device. I'll be happy to guide you with this.

To manage your account from your computer, you can either sign in through the Mac desktop app for QuickBooks Online or use a supported browser to log into your account. You can view the complete list of compatible browsers to the program here: System requirements for QuickBooks Online, Accountant, and QuickBooks Self-Employed 

I hope this helps! Let me know if there's anything else I can do to help.
