Ah ok - I see what IBM have done here:
1/ Changed the entire support model. Hired Apple experts and set up a dedicated help desk.
2/ Allow users full admin rights via a local account. No Active Directory connectivity
3/ Make users use Lotus Notes and Sametime (required a seperate Notes user name and password - no Single sign on)
4/ Limit the number of apps they can use. No VISIO or Project (for example). Solution is Citrix or local virtualisation product. They say majority of apps work. Be interesting to see what the apps are.
5/ Ship default image but configure at the users desktop. This takes a long time.
Essentially, they have redone the entire client compute model to use a totally different model, some would argue - compromise security, by providing local admin access in the pursuit of simplification and hire an 'expert' helpdesk dedicated to Macs, staffed by Mac advocates.
If they did the same for a Windows 7/10 PC - would the experience be any different?
This is my biggest issue with this report.
I work in enterprise ack ends for banks and financial institutions and if you just give every user a Mac, with this sort of "open" model, sure, there's likely going to be little overhead.
But banks, and enterprise or live in that world. GPOs and Active directory integration is insanely Important. I've seen such implementations that go as crazy restrictive so that the user can literally launch a single program. Or only have access to certain resources online, etc.
Currently there is no way I know of to enforce most of these GPOs onto a Mac. Which means its impossible in a corporate environment to properly secure macOS based systems to fit into corporate and regulatory compliance. This actually dramatically increases the cost of supporting macs. That and most of the worlds financial software is windows and unix based, with no MacOS support, requiring boot camps support or parallels. Not something large scale enterprises want to spend time and money on, when they can just get the windows machines that offer these required functions out of the box
And if IBM is making the claim they are, then they shouldn't need Citrix, which is essentially a fancy RDS. Which isn't cheap or easy to implement. So they've just moved the costs of support from the end user workstation to the Citrix back office. That has nothing to do with windows or OSX. And it makes IBMs claims dubious and sounds more like marketing than a real world benefit
