My father’s decidedly non-nerdy logistics consulting business with roughly 20 employees ran (and runs) on Mac OS since the founding of the company in the mid 1990s with my mom being the „IT team“. There are some situations where companies rely on certain compatibilities requiring windows. But most could do completely fine without, especially nowadays.
You can run a logistics consulting business without windows, but you will struggle without Excel and PowerPoint, and 365 with SharePoint is basically needed for collaboration in any consulting business.
Im also a logistics consultant… try to parse a multi-million line orderlines extract in Google Sheets compared to excel.
I’m also on Mac but to be honest it’s a challenge - there are still enough industry specific tools that are windows only so I have to run a parallels VM to get by.
