Mac IT support, UK
In many organisations, Macs are the devices IT knows least about: set up by hand, updated when people get round to it, and signed in with a separate password. Our Mac IT support manages your Macs to the same standard as your Windows PCs, for businesses across the UK, from our team in Canary Wharf.
The Mac support review
Trusted by teams across UK government, healthcare, education, charities, financial services and global brands
Most IT is built around Windows. Macs get added later, often with less control, less reporting and more manual work. These are the four gaps we see most.
Onboarding
Someone unboxes the Mac, creates an account and installs apps one by one. Nothing stops a user removing management later.
What we doWe register your Macs in Apple Business and use Automated Device Enrollment, so each Mac sets itself up from the box. On supervised Macs, users cannot remove management.
Updates
macOS Golden Gate 27 no longer supports the older ways of managing updates. Scripts and reminders that worked before stop working.
What we doWe use Apple’s declarative software updates: a target version and a deadline. The Mac installs by the deadline and reports its status back.
Identity
People keep a local Mac password that never changes, and some use personal Apple Accounts for work.
What we doPlatform SSO lets people sign in to their Mac with their Microsoft Entra ID account. Managed Apple Accounts can be federated with Entra ID too.
Security
From macOS 26.4, FileVault is on by default during setup. But without management, nobody holds the recovery key and users can turn it off.
What we doWe enforce FileVault and escrow the recovery key, then report each Mac’s compliance to Entra ID so Conditional Access can block Macs that fall short.
The same standards your Windows PCs already meet, applied to every Mac.
| Area | Unmanaged Macs | Macs managed by Postremo |
|---|---|---|
| New starters | UnmanagedA Mac set up by hand, with apps added over the first week. | Managed by PostremoThe Mac enrols itself from the box through Apple Business and is ready when the person signs in. |
| Updates | UnmanagedReminders, scripts and Macs that fall months behind. | Managed by PostremoUpdates enforced by a deadline, with each Mac reporting where it is. |
| Sign-in | UnmanagedA local Mac password, separate from Microsoft 365. | Managed by PostremoPeople sign in to the Mac with their Microsoft Entra ID account through Platform SSO. |
| Encryption | UnmanagedFileVault status unknown and recovery keys missing. | Managed by PostremoFileVault enforced, recovery keys escrowed and users unable to turn it off. |
| Access to data | UnmanagedAny Mac with a password can reach Microsoft 365. | Managed by PostremoConditional Access lets in compliant Macs, the same way it does for Windows PCs. |
| Planning | UnmanagedNo view of which Macs can run the latest macOS. | Managed by PostremoA clear list of Intel Macs that cannot move to macOS 27, so replacements are planned and budgeted. |
Four steps. It starts with a review, and you decide how far to go: fix the gaps yourself, or have us run your Macs day to day.
Mac support review
We look at every Mac you have: model, macOS version, how it is enrolled, FileVault, updates and who can sign in. We also show which Intel Macs cannot move to macOS 27, so replacements can be planned.
Book a Mac support reviewEvery Mac under management
We connect Apple Business to Jamf Pro or Microsoft Intune and enrol new Macs through Automated Device Enrollment. Existing Macs are brought in with as little disruption as we can manage. FileVault, firewall and update policies go on as standard.
One account for Mac and Microsoft 365
We set up Platform SSO so people sign in to their Mac with their Entra ID account, and federate Managed Apple Accounts where it fits. Mac compliance is reported to Entra ID so Conditional Access treats Mac and Windows the same.
Day-to-day Mac support
Our helpdesk supports your people on Mac and Windows, remotely across the UK and on site in London. We run updates by deadline, handle starters and leavers, and review the estate with you regularly.
Mixed Mac and Windows estates are where we do our best work. You do not need two IT suppliers, or one that treats the Mac as an afterthought.
Jamf Pro is built for Apple and suits organisations with many Macs or demanding security needs. Microsoft Intune manages Macs too, including Automated Device Enrollment, compliance and FileVault, and can suit a smaller Mac estate already on Microsoft 365. Jamf Pro can also report Mac compliance to Entra ID, so you keep one set of access rules.
We are a Jamf Professional Partner and Jamf MSP, and a UK Microsoft Cloud Solution Provider, so we recommend what fits rather than what we sell. Our Jamf vs Intune guide sets out the differences.
Organisations in London and across the UK that rely on Macs, usually alongside Windows.
Your design, engineering or leadership team has moved to Mac, but your IT was built for Windows. We bring the Macs up to the same standard and support both.
You run mostly Macs and need someone who knows Jamf, Apple Business and macOS releases well. Our managed IT support covers the whole estate.
Financial services, legal and other businesses that must show every device is encrypted, updated and controlled. For example, we moved a global trading company from 65% to 98% of Macs up to date in four weeks.

Our Mac IT support covers helpdesk support for your people, Mac management in Jamf Pro or Microsoft Intune, updates enforced by deadline, FileVault encryption, sign-in with Microsoft Entra ID, and starters and leavers. We support Windows PCs and Microsoft 365 alongside.
Managed support starts from £25 per device per month, excluding VAT and licences, such as Jamf or Microsoft 365. We quote a fixed monthly price after the Mac support review. See our pricing.
Both can manage Macs well. Jamf Pro is built for Apple and suits larger or security-sensitive Mac estates. Intune can suit a smaller Mac estate already on Microsoft 365. We are partners of both and recommend what fits.
Yes. Platform SSO lets people sign in to a managed Mac with their Microsoft Entra ID account, so there is no separate Mac password to remember. It works with both Jamf Pro and Intune.
macOS Golden Gate 27 runs only on Apple silicon Macs, so Intel Macs cannot upgrade to it. Apple released security updates for macOS Tahoe 26 and Sequoia 15 as recently as November 2026. Our review lists your Intel Macs so you can plan replacements.
Yes. Our team is based at One Canada Square in Canary Wharf and visits clients across London. We support clients across the UK remotely, Monday to Friday, 9am to 6pm.
Tell us how many Macs you have and how they are managed today. We will review them, show you the gaps and give you a clear plan, with a fixed monthly price if you want us to run them. We work across the UK from Canary Wharf, with on-site support across London. Managing iPhones and iPads too? See Apple IT support in London.
