Windows and Mac in the same company: how to keep a mixed environment under control

The designer has a Mac, sales has Windows machines, and everyone has an iPhone or an Android. This is everyday reality in a growing number of Finnish companies — and there is nothing wrong with it. A problem only arises when the IT partner masters just one of the two worlds: then the Macs are left without support, updates and backups only cover part of the fleet, and there is a gap in security that no one owns.

Why do mixed environments come about?

Few companies choose a mixed environment — it just happens. Creative work and software development gravitate towards Macs, financial administration and ERP software keep people on Windows, and in recruitment a new hire brings their habits with them. The end result is a device fleet with both, permanently. The sensible question is not “which one do we standardise on” but “how do we keep both under control”.

Do shared tools work on both?

Yes — this is the easiest part of a mixed environment. Microsoft 365 works on the Mac too: email, calendars, Teams and shared files are the same regardless of the device. In practice, the tools of everyday work no longer force an operating system choice; the choice can be made based on the work and the person doing it.

How are the devices kept under control?

An unmanaged computer is a risk regardless of the brand. In a mixed environment, management is built so that both worlds are in the same view:

• Apple Business Manager ties the company’s Macs, iPhones and iPads to the organisation’s ownership, so they can be deployed and reset in a controlled way.
• Microsoft Intune manages both Windows and macOS devices from one place: policies, applications and updates with a single tool.
• Even in a lighter model, the minimum requirement is the same: every computer is accounted for, receives updates, and can be wiped if it goes missing or a departing employee forgets to return it.

What about security and backups?

Both operating systems have good protections — as long as they are switched on across the entire fleet. On the Mac, disk encryption is handled with FileVault; on Windows, with BitLocker. The same goes for backups and multi-factor authentication: the policy is the same, the tool is chosen to match the device. The most dangerous situation is one where the protections are defined for only one half of the fleet and the other half runs on memory alone.

What usually causes problems in a mixed environment?

In our experience, rarely the technology. The most common cause is that responsibility is divided unevenly: the Windows machines have a partner and processes, while the Macs get looked after “when someone has a moment”. The other common cause is a lack of ground rules — no one has decided what gets installed for a new Mac user and who does it. Both are fixed the same way: a mixed environment needs to be run as one whole, not as two separate islands.

How do you get started?

Three steps go a long way. First, map the entire fleet: what devices there are, who manages them and which ones are outside management. Then decide on shared policies — encryption, updates, backups and authentication — that apply to every device regardless of brand. And finally, make sure support covers both worlds: one number to call for help with a Mac and with Windows alike.

At Developit, a mixed environment is business as usual, not a special case — a significant share of our customers’ devices are Apple’s. Get to know our Apple support, or tell us about your situation and we’ll look at the whole picture together.
