MacBook Air tricks that make a small screen feel less crowded

A MacBook Air is rarely short of speed. What it is short of is width. Everything that goes wrong on one during a working day traces back to the same thing: too many windows and too many icons competing for a screen that is smaller than the one the software was designed on. The Dock takes a strip off the bottom. The menu bar takes a strip off the top. Whatever is left has to hold two documents side by side.

So the tricks worth learning on an Air are not the ones that look clever. They are the ones that hand space back, and macOS 27 has more of them than the setup assistant mentions.

Spaces cost nothing and behave like extra screens

The single biggest change available to a small screen is also the oldest. Mission Control can hold up to sixteen separate desktops, called spaces, and only the windows belonging to the current space are drawn. Instead of arranging eight windows on one screen, put two on each of four screens.

Creating one takes a moment. Enter Mission Control, then click the add button in the Spaces bar along the top. Switching between them is where the time is saved: Control and the Left or Right Arrow key moves one space over, and a three or four finger swipe on the trackpad does the same thing. Neither requires looking at anything.

The setting that makes spaces stick is assignment. Control click an app icon in the Dock, choose Options, and choose an entry below Assign To. This Desktop pins the app to the space it is in now. All Desktops makes it follow you everywhere, which is the right choice for a messaging app or a terminal. None lets it open wherever you happen to be. Once mail lives in one space and the work lives in another, the switching becomes muscle memory rather than a decision.

One default is worth knowing about because it surprises people. Switching to an app normally jumps to whichever space already has a window of that app open, so a new document can appear somewhere unexpected. The switch labelled "When switching to an application, switch to a Space with open windows for the application" in Desktop and Dock settings, under Mission Control, turns that off.

Dragging a window to the edge of the screen and holding it there for a moment moves it to the next space, which is the fastest way to redistribute a mess without entering Mission Control at all.

Spaces are easier to tell apart when they look different. Assign System Settings to all desktops, then set a different wallpaper in each one, and the swipe stops being a guess. Deleting a space is equally quick: enter Mission Control, hold the pointer over the space in the Spaces bar, and click the close button that appears. Any windows it held are moved to another space rather than closed, so nothing is lost by experimenting with the arrangement.

Tiling, and the case for not tiling

Two windows side by side is the obvious layout, and on a 13 inch screen it is often the wrong one. Halving the width of a browser window that was already narrow produces two columns that neither document is comfortable in.

When it is right, the keyboard is faster than the drag. Fn, Control and the Left or Right Arrow key moves the active window to that half. Fn, Control, Shift and Left Arrow places two windows at once, the active one on the left and the next one on the right. Fn, Control and F fills the desktop with the active window. Fn, Control and R returns a window to whatever size it had before it was tiled, which is the escape hatch for a layout that turned out badly.

Holding Option while dragging a window toward an edge tiles it without the pointer having to travel all the way, which matters on a trackpad.

When tiling is wrong, full screen is usually right. Taking one app full screen gives it the whole panel and moves it into its own space, so Control and the arrow keys still reach everything else in one keystroke. On a small display this is frequently a better answer than splitting the screen, because the cost of switching has already been reduced to a single key.

Stage Manager, for the days with too many windows

Stage Manager keeps the window being worked on in the centre and lines recently used apps down the left edge. It is off by default and lives in System Settings under Desktop and Dock, in the section headed Desktop and Stage Manager. Control Center has a switch for it as well.

Two of its settings decide whether it helps or annoys on a small screen. Turning off "Show recent apps in Stage Manager" hides the strip down the left, which is the part that costs width, and the strip still appears when the pointer moves to the left edge. The pop up menu for showing windows from an application offers All at Once or One at a Time, and One at a Time is the setting that matches what a small screen is for.

If Stage Manager refuses to turn on, the cause is a Mission Control setting. "Displays have separate Spaces" has to be on for it to be available.

The Dock and the menu bar take the same bite

Both strips are permanent by default, and both can be made conditional.

The Dock has an automatic hide switch in Desktop and Dock settings, which returns the bottom of the screen and brings the Dock back when the pointer reaches that edge. Moving the Dock to the left or right edge is the other option, and on a wide but short screen it is often the better one, because vertical space is scarcer than horizontal. Turning off magnification and reducing the size slider both help once the Dock is hiding, since a hidden Dock that leaps to full size on approach is harder to aim at.

The menu bar has four settings rather than a switch, in System Settings under Menu Bar. Always hides it everywhere. On Desktop Only hides it when no app window is in front. In Full Screen Only is the shipped behaviour. Never keeps it there even in full screen.

The trade is not symmetrical. Hiding the Dock costs almost nothing, because the Dock is a launcher and Command and Space bar is faster anyway. Hiding the menu bar costs a great deal, because the clock, the battery, the Wi-Fi indicator and every status icon exist to be read at a glance, and a summoned indicator is not an indicator.

Setting	Space returned	What it costs
Automatically hide the Dock	The bottom strip	A pointer trip to launch an app
Move the Dock to a side edge	Height, which is the scarce axis	Horizontal room when it is showing
Hide the menu bar always	The top strip	Every glanceable indicator
Use spaces instead of tiling	No pixels, but no crowding either	Learning two arrow keys
Full screen for one app	Both strips, for that app	Nothing, once spaces are in use

Spotlight does most of what the Dock was for

The argument for hiding the Dock only holds if launching apps is genuinely faster another way, and on macOS 27 it is. Command and Space bar opens Spotlight, typing two or three letters finds the app, and Return opens it. That is quicker than moving a pointer to the bottom of the screen and picking an icon out of a row, and it costs no screen at all.

What makes it a real replacement rather than a substitute is everything else Spotlight now does from the same window. Pressing the Space bar on a highlighted result opens Quick Look, which previews documents, images, PDFs and video without launching the app that owns them, so a file can be checked and dismissed without a window ever appearing. On a small screen that is the saving that repeats most often.

Pressing Tab on a highlighted result reveals Quick Actions, and what is offered depends on what is selected. Holding Command on a highlighted result reveals the file in the Finder instead of opening it.

Spotlight also answers questions that would otherwise mean opening something. Typing a math expression gives the answer in the search field, so percentages and multiplication resolve without Calculator. Unit and currency conversion work the same way with an ordinary phrasing such as 5 miles in km. Typing a single word shows its definition without opening Dictionary. Clipboard history is searchable from the same field, which removes the usual reason to install a separate utility, and pressing the Up Arrow recalls the previous search.

The practical effect on an Air is that the Dock stops being a place things are launched from and becomes a place that shows what is already running. Once that is true, hiding it costs nothing, and the bottom strip comes back.

Two adjustments make a hidden Dock more usable. Turning off magnification stops the icons leaping to full size on approach, which makes them easier to hit. Turning off "Show suggested and recent apps in Dock" stops the row changing width, so the icons stay where the hand expects them.

Keep the top strip, thin what is in it

Given that trade, the better move on an Air is to leave the menu bar visible and reduce what it holds.

Menu Bar settings in macOS 27 has a section called Menu Bar Controls listing the system items: Wi-Fi, Bluetooth, Battery, Focus, Screen Mirroring, Display, Sound, Now Playing, Fast User Switching, Time Machine, VPN and Weather. Several offer a pop up menu with Show When Active and Always Show. Show When Active is the setting most of them deserve, because the icon then appears only when there is something to report, and anything switched off is still reachable by opening Control Center. Battery has an Options button for showing the charge percentage, which on a laptop is one of the few things genuinely worth permanent space.

Below that, Allow in the Menu Bar lists the apps that add their own icons, each with a switch. That is the section that actually shortens the row on a machine that has been in use for a year.

Two gestures finish it. Holding Command and dragging an icon sideways reorders the row. Holding Command and dragging one off the bar removes it.

When the row is still too long after all of that, because everything left in it is something that gets used, the remaining approach is to collapse most of it behind a divider and keep only what gets read. That is the job of a menu bar organizer, and the feature list and the side by side comparison set out how such tools differ from each other.

What to change first

Turn on automatic Dock hiding, then set up three spaces and assign mail and messaging to one of them. Those two changes give back more screen than anything else on this page. If the top of the screen is what still feels crowded afterwards, Koffret is built for that strip specifically.
