This reads like the last time you've evaluated is 2018. The entire office suite works great on Apple silicon with the exception of, obviously Win32 VBA macros and some PowerQuery features in Excel.

As for Adobe, I'm assuming you're issuing desktops then? Because for an equivalently performant laptop with heavy Adobe workloads you are going to spend the same as a MBP on the higher end Thinkpads, or dell precisions. There's no cost savings there, really (again, unless you have everyone on desktops).

If you're still domain joining macs, trying to use SCCM & GPOs, and treating them like any other windows endpoint, of course you are running into problems. Kind of a square peg/round hole situation.

Not doubting your experience, but to have relatively problem free mac endpoints you have to do things differently. Maybe not worth it for every company, especially any that are super deep into Microsoft. But I can say, they've worked great for mine and we are phasing out Windows entirely, and IBM, Cisco, and SAP all had similar lower total cost of ownership & less help desk workload after introducing macs. Then again, we no longer use smb/samba, we eliminated on-prem file shares a long time ago.

We use 10G fiber to a local file store. Not domain joined. Cloud is way too slow for media production (the users that Apple targets).

We use basic AV and monitoring, as required for carrying insurance.

We don't have any desktops.

Our comparisons are done regularly to show the difference to new employees and to ensure that we aren't biased in what we report for budgeting.
