Mac Setup for Students: Set It Up Once, Properly

A student Mac has to survive four years, a lot of coffee shops and one very bad week near a deadline. Set it up for that on day one: backups that run without you, a battery that lasts a lecture block, and a file system you can still navigate in third year.

Backups first, because you will need them

The single most valuable thing on this list. An external drive and ten minutes:

1. Plug in an external drive, ideally at least twice the size of your Mac's storage.
2. Open System Settings → General → Time Machine and add it as a backup disk.
3. Leave Back Up Automatically on. It runs hourly whenever the drive is connected.
4. Plug in once a week. Set a reminder if you need to.

Also turn on iCloud Drive with Desktop & Documents Folders in System Settings → Apple Account → iCloud. That covers the file you were editing when the laptop was stolen, which Time Machine sitting at home does not. The two together are belt and braces, and dissertations have been lost for want of either.

Find My, and a passcode that means something

System Settings → Apple Account → iCloud → Find My Mac. It lets you locate, lock or erase the machine remotely. Turn it on now, because you cannot turn it on afterwards.

While you are there, set Lock Screen → Require password immediately and give the Mac a real login password rather than four characters. A library desk is exactly the situation these settings exist for.

Storage, before it becomes a crisis

A 256 GB Mac fills faster than you expect. Check where it goes with System Settings → General → Storage, and turn on the two recommendations that are worth it: Empty Trash Automatically and Optimise Storage for videos you have already watched.

# the biggest folders in your home directory
du -sh ~/* 2>/dev/null | sort -h | tail -10

# how much space you have right now
df -h /

The usual offenders are downloads you never cleared, old installers, and iOS backups. None of them need a cleaning app to find.

Battery for a full day out of the house

• System Settings → Battery → Low Power Mode → Only on Battery. The largest single gain, and you will not notice it in normal use.
• Lock Screen → Turn display off on battery after 2 minutes. The display is most of your consumption.
• Battery → Options → Wake for network access → Never. Stops the Mac waking in your bag between lectures.
• Check Activity Monitor → Energy once. A single misbehaving app is usually the difference between a five-hour day and a nine-hour one.

Files you can still find in third year

Pick one structure and keep it. A folder per year, a folder per module inside it, and everything for that module in there — notes, readings, submissions. Drag the current term's folders to the Finder sidebar so they are one click away, and turn on View → Show Path Bar so you always know where a file actually lives.

Two Finder settings help immediately: Show all filename extensions, and setting search to Search the Current Folder in Finder → Settings → Advanced. The second one alone makes Finder's search useful.

The apps to install, and the ones to skip

Two categories genuinely help and are usually free with a student email: a reference manager if you write anything cited, and a note app you will actually open. Everything else can wait until you hit the problem it solves.

Skip the cleaners and optimisers entirely. macOS manages memory and caches itself, storage is visible in System Settings → General → Storage, and the apps that promise to speed up a Mac mostly delete caches the system rebuilds more slowly. If a Mac genuinely feels slow, the honest causes are a full disk, too many login items, or a browser with sixty tabs, and all three are free to fix.

Focus modes for lectures and for work

Make two in System Settings → Focus: one that silences everything for lectures, one for study sessions that still allows calls from family. Both sync to your phone. Notification badges are worth turning off under Options, because a red number is an interruption even without a sound.
