ITTA offers an Apple macOS catalogue focused on Apple OS administration in a professional environment. The MacOS Sonoma – Support Essentials 14 course covers macOS 14, its Apple Silicon specifics, user and permission management, security (FileVault, Gatekeeper, Secure Enclave), network, troubleshooting and multi-OS integration. Audience: Mac support technicians, fleet administrators and IT profiles in Apple environments. Sessions delivered in Geneva, Lausanne and interactive virtual classroom.

MacOS Sonoma Support Essentials 14 training in Geneva and Lausanne. Master configuration, troubleshooting and macOS management across 3 days.
macOS is Apple’s OS, specifically designed for its proprietary hardware (Mac, MacBook, Mac mini, Mac Studio, iMac, Mac Pro). This vertical hardware/software integration (Apple silicon, firmware, OS) is one of Apple’s strong specificities: unlike Windows or Linux that must support huge hardware diversity, macOS is optimised for a restricted hardware fleet, resulting in experience fluidity and system consistency often superior. The trade-off is strong dependence on Apple for hardware evolutions, design choices and update calendar.
In 2026, macOS pursues its annual release cycle (Sonoma macOS 14 in 2023, Sequoia macOS 15 in 2024, and following versions). Each version brings evolutions on productivity, security, fleet management and now Apple Intelligence (on-device AI and Private Cloud Compute). For IT profiles in charge of a Mac fleet, following macOS has become central, both to leverage novelties and anticipate version and hardware obsolescence.
Our macOS course in the ITTA catalogue:
This course is calibrated on the official Apple Support Essentials content for macOS Sonoma (macOS 14). It covers macOS installation and initial setup (Setup Assistant, configuration profiles, first settings), user account and permission management (administrator, standard, sharing only, POSIX and ACL permissions, per-user FileVault), system preferences and configuration profiles management (.mobileconfig), security (FileVault, Gatekeeper, XProtect, T2/Apple Silicon Secure Enclave, automatic updates, application signature and notarisation), storage management with APFS (partitions, volumes, snapshots, FileVault), Time Machine backups (local, NAS, snapshots), network (Wi-Fi, VPN, SMB/AFP shares, AirDrop), application management, basic troubleshooting (Recovery, verbose mode, console, unified logs), and integration in multi-OS environment (Active Directory, Azure AD/Entra ID, Windows shares, printing).
A significant part of the course covers the Apple Silicon transition that deeply modified macOS over recent years. Apple Silicon Macs (M1, M2, M3, M4) differ from older Intel Macs on several aspects: ARM architecture (Universal binaries or Rosetta 2 execution), integrated Secure Enclave, boot in 1TR mode (One True Recovery), different FileVault management, stricter security runtime, native iOS apps support. Understanding these differences is central to administer a modern fleet. The course addresses these aspects, what concretely changes for support and administration, and how to manage a mixed Intel + Apple Silicon fleet in transition.
Our macOS audience is targeted. You meet L1/L2 support technicians in majority or minority Mac environments responding to Mac users, fleet administrators managing a mixed Windows/Mac fleet wanting a solid macOS foundation, IT teams in agencies or media wanting to professionalise Mac management, integrators and consultants intervening at clients on Mac fleet projects, security profiles needing to understand macOS security specifics (vs Windows or Linux), dev or DevOps wanting to understand macOS beyond user usage, audit profiles evaluating a Mac fleet’s security posture.
macOS fits into a broader landscape covered by our catalogue. The parent Apple IT Pro publisher regroups all Apple training in professional environments. For profiles in mixed Windows/Mac environments, the Microsoft Windows publisher brings the Windows counterpart and enables a cross-platform view. The Microsoft 365 publisher is relevant for Microsoft 365 administration dimension (Intune also supports Apple MDM).
On the sub-domain side, systems and networks regroups system admin training for IT pros. For security profiles, the audit and cybersecurity sub-domain is complementary (macOS has its own endpoint security logic to know). For creative or multimedia profiles on the Mac content side, the Apple Final Cut Pro publisher addresses the Mac video creation dimension.
You have administered Windows for years and your organisation massively acquires Macs. The macOS Support Essentials course is the structured path to acquire the solid macOS foundation needed to correctly manage these machines. It also brings the culture needed to dialogue with MDM publishers (Jamf Pro, Intune, Mosyle, Kandji) on solid macOS concepts.
The course prepares for the Apple Certified Support Professional (ACSP) certification on macOS Sonoma. This certification is delivered by Apple via its referenced centres and is useful for integrators, consultants and profiles wanting to value a formally recognised Mac competency.
You inherit a Mac fleet that has expanded without a formal framework and you want to secure its management (configuration, update, backups, security). The macOS Support Essentials course brings the foundations needed to structure this fleet and prepare a coherent MDM.
Several trends shape macOS and Mac management in 2026. The Apple Silicon transition is now complete on new machines, progressively simplifying long-term management. Apple Intelligence (on-device AI and Private Cloud Compute) has been deployed since macOS Sequoia (15) and changes user usage (summaries, text generation, translation, image playground), with an on-device approach preserving privacy. Mac endpoint security has strongly evolved (Lockdown Mode for sensitive profiles, signature hardening, FileVault by default, actively-used Secure Enclave). MDM has become central, with Jamf Pro leading on Mac, Microsoft Intune progressing for Microsoft-first organisations, and Mosyle / Kandji as lighter alternatives. Apple Business Manager and zero-touch deployment are the norm on at-scale deployments.
On the software side, iOS/iPadOS/macOS coexistence is more pushed (Continuity, iCloud, Universal Control, Handoff) and Mac usage in mixed contexts (mobility with iPad, field with iPhone) is progressing.
Our macOS Support Essentials sessions are scheduled in Geneva, Lausanne and in interactive virtual classroom with a live trainer. The course is very practice-oriented. Material modalities for in-person sessions are communicated in advance by our education team. For IT teams in majority Mac environments (agencies, media, private banks, international organisations), we organise in-house sessions calibrated on your real fleet (deployed macOS versions, MDM used, AD/Entra ID integration, LOB applications). This modality is highly requested in French-speaking Switzerland in sectors where Mac is largely deployed.
Do I need prior Mac experience as a user to follow?
Regular prior macOS use is very useful. The course targets IT profiles, not full discoveries of the Apple world. For 100% Windows profiles with no Mac experience, a few weeks of prior macOS practice are recommended.
Does the course cover macOS Sequoia (15) instead of Sonoma (14)?
The Support Essentials course follows the official Apple version in effect at the session time. Sonoma remains very present in fleets in 2026. Fundamentals remain largely transferable to Sequoia and following versions. Sequoia novelties are addressed as a complement.
Does the course really prepare for ACSP certification?
Yes. The content follows the official Apple Support Essentials programme for macOS Sonoma. The course prepares for the ACSP exam, then taken at an Apple-referenced centre.
Does the course cover Jamf Pro or Intune?
The Support Essentials course focuses on macOS itself. MDMs (Jamf Pro, Intune, Mosyle, Kandji) are addressed conceptually but are not the main subject. To go further on MDM, specific sessions can be organised in-house depending on your tool choice.
ITTA offers a coherent IT pro catalogue from Windows to macOS, through Microsoft 365, Azure, AWS and security, network and virtualisation topics. This continuity is valuable for IT profiles managing a mixed fleet or shifting their expertise to Apple. Our macOS trainers are integrators and consultants active on Mac fleets in French-speaking Switzerland, providing concrete examples on integration in historical Microsoft environments, MDM deployments, Mac security and long-term management. Sessions available in Geneva, Lausanne and interactive virtual classroom, in-house and inter-company.
