After three interviews, I landed a three-month contract as a systems administrator in an environment that is reportedly about 80% Mac-based. I've had very little hands-on experience with Apple computers, so I'd like to use the time before I start to close the biggest gaps in my knowledge. What short courses, official training, documentation, or practical topics would you recommend? I'm not yet sure which macOS versions, management tools, or infrastructure responsibilities I'll be working with.

Start with Apple’s official macOS user and IT documentation, then use the Apple IT training material to identify the areas you need to study. Videos and practice exams can help fill in specific gaps. For practical skills, focus on macOS administration, user and permissions management, software installation, security controls such as Gatekeeper, troubleshooting, MDM concepts, and common deployment workflows.
First find out what the role actually covers. An organization with mostly Macs might still run its servers, identity systems, and core infrastructure on Windows or Linux. Ask whether they use an MDM platform, whether you’ll be expected to manage it, what your teammates handle, and whether scripting or automation is part of the job. The difference between supporting Mac endpoints and administering an Apple-centered infrastructure can be pretty significant.
Try to confirm which macOS versions and Apple hardware you’ll actually support before choosing a course. Apple’s naming and version numbers have changed over time, so material aimed at an older release may not match the current environment. If you can get access to a Mac beforehand, spend some time practicing everyday administration tasks rather than only watching training videos.
It’s also worth getting comfortable with Terminal. macOS is built on Unix, so many commands and tools will feel familiar if you’ve used Linux. You don’t need to memorize everything before starting, but basic shell navigation, permissions, processes, logs, networking, and package or software management will be useful.
