Adding items to the Finder sidebar so they stay put

A project folder gets opened forty times a week, and every one of those times starts the same way: a new Finder window, then four clicks down through the home folder. The sidebar exists to remove exactly that, and adding something to it takes about two seconds once the right route is known. The confusion is not really about how to add. It is about why a dragged folder sometimes refuses to land, why Finder Settings shows a list that does not include anything already added, and why an entry that worked last month now opens nothing.

What the Favorites list actually holds

The sidebar is divided into sections, and only one of them is under direct control. Favorites is the top section and it is a hand made list. Below it sit iCloud, Locations, and Tags, and those are populated by the system: mounted disks, connected servers, and the tag set appear there without being asked for.

An entry in Favorites is not a copy of the folder and not a plain path string either. It is a reference the system stores on the reader's behalf, which is why renaming a folder usually leaves its sidebar entry working. The entry is pointing at the folder, not at the letters in its name. Move the folder to a different location on the same disk and the same thing generally holds.

Two consequences follow from that, and both are the source of most sidebar complaints. First, removing an entry from the sidebar never touches the folder. There is no undo prompt because nothing is being deleted. Second, an entry can outlive the thing it points at. Delete the folder itself, or unplug the disk it lives on, and the entry either dims or stops responding, because the reference now resolves to nothing.

Knowing which of those two is happening takes one click. If the entry is greyed out, the volume is not mounted. If it is fully drawn but clicking it does nothing useful, the target is gone.

Three routes that add an item

Dragging is the fastest route and the one that fails most often. Drag the folder over the Favorites section and watch for a horizontal insertion line to appear between two existing entries. The line is the signal that the drop will be accepted. If the drop happens while an existing folder entry is highlighted instead, the folder is being moved into that folder, which is a very different outcome and one worth checking for immediately with an undo.

The keyboard route avoids that ambiguity entirely. Select the item and press Control-Command-T. Apple documents the shortcut plainly in its keyboard shortcut list, described as adding the selected item to the sidebar, and it has behaved that way since OS X Mavericks. Nothing needs to be dragged and there is no insertion line to aim at. The item lands at the bottom of Favorites and can be dragged into position afterwards.

The third route is the File menu, which carries an Add to Sidebar command with that same shortcut printed next to it. It is worth opening once, because the menu is also where the reader can confirm whether the currently selected item is eligible at all. When the command is dimmed, the selection is something the sidebar will not take, and no amount of dragging will change that.

For folders that do not exist yet, there is a shortcut worth combining. Create the folder with Shift-Command-N, name it, and add it with Control-Command-T while it is still selected. Three keystrokes total, no window switching.

Finder Settings controls a different list

Open Finder Settings and there is a Sidebar tab full of checkboxes: Recents, AirDrop, Applications, Documents, Downloads, iCloud Drive, external disks, connected servers, and so on. It looks like the master list of the sidebar, and it is not.

That tab governs the standard items only. Anything added by hand does not appear as a checkbox there, and never will. Adding a folder to Favorites and then hunting for its checkbox in Settings is a dead end that costs people a surprising amount of time.

The tab is still worth a visit, for the opposite reason. Most sidebars are cluttered with defaults nobody uses. Turning off Recents, AirDrop, and the sections for disc media makes room for the entries that matter, and none of those toggles removes anything from the disk. The Locations checkboxes are the ones to think about hardest, because turning off external disks means a plugged in drive will not announce itself in the sidebar at all.

There is also a per section control that is easy to miss. Hovering over a section heading reveals a Hide or Show control on the right, which collapses the whole section. A sidebar that suddenly appears to have lost its Tags is usually a collapsed section rather than a lost setting.

Applications, disks, and the things the list will not take

Favorites is not restricted to folders. An application can be dropped there, which turns the sidebar into a launcher for the two or three apps that get opened from a file window rather than from the Dock. A mounted volume can be added, and so can a folder that lives on that volume, though the two behave differently: the volume entry disappears when the disk is ejected, while a folder entry on that volume stays visible and goes dim.

The useful test for anything else is the File menu. Select the item, open the menu, and look at whether Add to Sidebar is available. A dimmed command is the system saying the selection is not something it will store a reference to, and that answer arrives faster than repeated dragging.

One case deserves a separate mention because it looks like a bug. A folder inside iCloud Drive can be added like any other, but if that folder has been evicted from local storage to save space, the entry resolves to a placeholder rather than to visible contents. Nothing is lost. The folder downloads on demand when opened, and the delay before the window fills is the download, not a broken entry.

Files themselves are the ambiguous case. The sidebar is built around places, and a single document sitting between two folders in the list tends to be a slot that gets clicked by accident. Tags handle that need better, because a tagged file can be reached from the Tags section without occupying a Favorites row.

Second machines do not inherit the list

The Favorites list belongs to one user account on one Mac. Signing into iCloud on a second machine brings across documents, passwords, and a great deal else, and it does not bring across the sidebar. Setting up a replacement Mac and finding an empty Favorites list is expected behaviour rather than a failed migration.

That has a practical consequence for anyone who works across two machines. Entries pointing at local paths cannot be reproduced by hand on the other Mac unless the same folder structure exists there. Entries pointing into iCloud Drive can, because the target exists on both. For a folder that genuinely needs to be one keystroke away on every machine, the location it lives in matters more than the sidebar entry does.

Migration Assistant is the exception, since a full transfer carries account level settings across with everything else. A manual setup, or a clean install followed by copying folders over, does not.

When an entry goes missing

Entries disappear for a small number of reasons, and they are worth checking in order rather than reaching for a rebuild.

What is seen	Most likely cause	What resolves it
Entry is greyed out	The volume it lives on is not mounted	Reconnect the disk or the server
Entry opens the wrong folder	Two folders had the same name and one was replaced	Remove and add again from the correct location
Entry gone after a restart	The folder was on an external disk that was absent at login	Add it back once the disk is mounted
Whole Favorites section empty	The section is collapsed, not cleared	Hover the heading and click Show
Sidebar itself missing	The sidebar is hidden	Press Option-Command-S

Server shortcuts deserve their own note. A mounted network share can be added to Favorites like any folder, and clicking it later will attempt to reconnect rather than failing outright. That makes it the most valuable kind of sidebar entry for anyone working against a shared volume, and also the one most likely to look broken, because the reconnection depends on credentials that may have expired.

Removing an entry is done by Control-clicking it and choosing Remove from Sidebar. Dragging it out of the sidebar also works. Neither deletes anything, which is worth saying twice because the drag out gesture looks destructive.

The sidebar is a list of places, not of work

There is a limit built into the idea. The sidebar holds locations. It does not hold a question like "everything a colleague sent this week that is still unread", because that is not a place.

Smart folders close part of that gap. Press Option-Command-N for a new smart folder, set the criteria, save it, and the save dialog offers a checkbox to add it to the sidebar. The result behaves like a folder in the sidebar but its contents are a live search. For recurring questions rather than recurring destinations, this is the entry type that earns its slot.

The other honest answer is that a long Favorites list stops working as an index. Past roughly a dozen entries the eye has to scan rather than aim, and the time saved per click starts going back the other way. A tighter list plus the Go menu shortcuts tends to beat a long list. Shift-Command-O opens Documents, Shift-Command-D opens Desktop, Shift-Command-H opens Home, Option-Command-L opens Downloads, and Shift-Command-G opens the Go to Folder field where a typed path beats any amount of clicking.

Those standard destinations do not need sidebar slots at all, which frees the sidebar for the four or five project folders that actually change month to month.

Where the sidebar stops helping

Every route above ends the same way: a folder window opens, and then the actual work starts somewhere else. A terminal for the command that has to run against those files. A browser for the thing being downloaded into them. A chat window for the question about what is in them. The sidebar shortened the first step of that sequence and left the rest alone.

That is a reasonable division of labour for occasional work and a poor one for daily work. A file manager with a built in terminal removes the second window rather than the first, which is the larger of the two costs for anyone whose folders are also working directories. The trade-offs between the available tools are laid out in Compared with other file managers, including which of them keep a shell attached to the visible folder, and the practical limits are covered in the FAQ.

What to change first

Spend five minutes in Finder Settings turning off the standard sidebar items that never get clicked, then add the three or four folders that carry current work using Control-Command-T. That combination does more than adding entries alone, because the value of the sidebar comes from its shortness. If the remaining friction is switching from the folder window to a shell for every command, that is the part Atriens is built to remove.
