Question for UK Mac users only and MTD VAT

For those of us who are VAT registered and using Macs only, have any of you had success with an appropriate application to submit your VAT now we all have to the MTD route? Nearly all the suitable apps are on subscription only (thanks a bunch Adobe) and some are not cheap. For my money either Portico or https://123sheets.com/ seem reasonable. Anyone had any success with MTD?
