How to Search on Mac: Spotlight, Finder, Shortcuts & AI Memory Search
A comprehensive guide to finding any file, folder, application, open window, or text snippet on macOS Sonoma & Sequoia — from essential shortcuts to AI-powered natural language search.
The Essential Mac Search Shortcuts
Whether you are searching your entire hard drive, looking inside a specific folder, or finding text within an open document, here are the primary shortcuts on macOS:
| Keyboard Shortcut | Tool / Scope | What It Does |
|---|---|---|
| ⌘ Space | Spotlight Search | Universal search for files, apps, web, conversions, and math anywhere on macOS. |
| ⌘ F | Finder / In-App Search | Searches within the active folder in Finder, or finds text/words in Safari, Preview, and Docs. |
| ⌥ ⌘ Space | Finder Search Window | Opens a dedicated Finder search window scoped to your entire Mac with advanced criteria filters. |
| ⌘ Shift G | Go to Folder | Direct path navigation in Finder (e.g., ~/Downloads or /Library/Application Support). |
| ⌥ Space | SearchOnMac (AI Launcher) | Natural language search by memory, recency, open windows, browser tabs, and clipboard history. |
How to Search on Mac Using Spotlight (⌘ Space)
Spotlight is macOS's built-in universal launcher and indexing engine. It scans file names, document contents, applications, system settings, and Apple services.
1Basic Search & App Launching
Press ⌘ Space, type an app or file name, and press ↵ Return to launch or open. Press ⌘ ↵ to reveal the file in Finder.
2Quick Math & Conversions
Type equations like 145 * 1.18 or currency queries like 50 USD in EUR. Spotlight solves calculations instantly without opening Calculator.
Spotlight Power Keywords & Search Operators:
- kind:pdf — Search only PDF files
- kind:image — Search images & photos
- date:today — Files modified today
- author:"Name" — Search by author tag
How to Search Inside Finder with Filters (⌘ F)
When you need to search a specific folder or apply granular criteria (such as file size, creation date, or hidden system files), Finder’s built-in search bar provides deep filtering.
Open Finder and press ⌘ F. By default, Finder lets you toggle between searching your entire Mac or strictly inside the folder you are currently viewing.
Click the + button on the top right below the search bar to filter by:
- Kind: Document, Image, PDF, Application, Folder, Movie
- Last modified date: within last 7 days, today, or exact range
- File Size: greater than 100 MB (great for freeing disk space)
- System files: choose “System files are included” to find hidden library files
Can You “Control F” on a Mac?
If you are transitioning from Windows, you might wonder why Ctrl + F doesn’t work. On macOS, the Command key (⌘) replaces the Windows Control (Ctrl) key for almost all standard operations.
Press ⌘ F in Safari or Chrome to find words on webpages, in Preview to search inside PDF documents, or in Notes / Word to search text.
How to Search for Words Inside Files & PDFs on Mac
When you don’t remember a file name but remember a specific sentence, number, or invoice header, macOS gives you multiple methods to search deep within file contents:
1. Exact Phrase Search in Spotlight
Wrap your search term in quotation marks in Spotlight: "quarterly operating revenue". Spotlight will restrict matches to files containing that exact sequence of words.
2. Searching in Preview.app
Open any PDF or scanned document in Preview and press ⌘ F. Preview opens a side search drawer highlighting every occurrence across pages.
3. Deep On-Device Content Search with SearchOnMac
SearchOnMac indexes the body text of PDFs, Word documents, Markdown files, and screenshot OCR locally on your Apple Silicon chip. Press ⌥ Space and type the content you remember; view the text preview instantly with ⌘ Y.
How to Search on Mac Using Terminal (mdfind & find)
For developers, sysadmins, and terminal enthusiasts, macOS provides powerful command-line search tools that bypass GUI animations:
# 1. Instant Spotlight CLI query for any file matching keyword
mdfind "financial summary"
# 2. Search only inside ~/Downloads for PDFs
mdfind -onlyin ~/Downloads "kMDItemContentType == 'com.adobe.pdf'"
# 3. Direct file system scan for files modified in the last 24 hours
find ~/Projects -type f -mtime -1
# 4. Search text inside code files with ripgrep or grep
grep -rn "handleAuthCallback" ~/Projects/recall/
The Next Generation: Natural Language Search with SearchOnMac (⌥ Space)
The biggest flaw in traditional search tools is that they force you to remember exact filenames. But human memory recalls context, recency, and what you were doing.
Search the Way You Remember
Type queries like "the pdf I downloaded this morning" or "the terminal where flutter failed". The local intent parser resolves folder hints, time ranges, and resource types in <5 ms.
Four Local Sources in One
Instantly searches your Files, installed & running Applications, open Windows & Tabs across 8 browsers, and the last 100 items in your Clipboard History.
SearchOnMac never sends your files, queries, clipboard history, or screen contents to any cloud server. All AI decision ranking runs locally on your Mac via Apple Silicon Neural Engine / Laya-MLX.

Common Questions on Searching on Mac
What is the shortcut for search in Mac?
The primary shortcut to search on Mac is Command + Spacebar (⌘ Space), which opens Spotlight Search from anywhere. Inside Finder, Safari, Preview, and most Mac apps, press Command + F (⌘ F) to search for files, text, or words on the active screen.
Can you Control F on a Mac?
Yes! On macOS, the Command key (⌘) replaces the Windows Control (Ctrl) key for keyboard shortcuts. To 'Control F' on Mac, press Command + F (⌘ F). This shortcut finds words on webpages in Safari or Chrome, searches documents in Preview or Pages, and opens the search bar in Finder.
How do I search for text or words inside files and PDFs on Mac?
In Spotlight (⌘ Space), simply type the word or phrase; Spotlight automatically indexes text inside documents, PDFs, and emails. In Finder, press ⌘ F, choose 'This Mac', and type the word. In an open PDF or document in Preview, press ⌘ F and enter the keyword to jump between matches.
What is the search key on a MacBook keyboard?
On modern MacBook keyboards (M1, M2, M3, M4 series), Apple includes a dedicated Magnifying Glass icon on the F5 or F6 function key. Pressing this key triggers Spotlight Search. Alternatively, the universal keyboard shortcut on all Macs is Command + Spacebar.
How do I search for an application on Mac?
Press Command + Spacebar (⌘ Space) to open Spotlight, type the first few letters of the app name (e.g., 'term' for Terminal or 'xco' for Xcode), and press Return (↵) to launch it immediately.
What is the best search software for Mac?
While macOS includes Spotlight and Finder for basic searches, SearchOnMac is the leading modern Mac search utility for natural language and memory-based queries (e.g., 'the pdf I downloaded this morning' or 'the terminal where flutter failed'). Other popular utilities include Alfred and Raycast for launcher workflows, and HoudahSpot for complex boolean file filtering.
Why is Spotlight search not finding my files?
Spotlight can fail if its index (.Spotlight-V100) becomes corrupted or stuck after a macOS update, or if the folder was added to System Settings > Siri & Spotlight > Spotlight Privacy. You can rebuild the index in Terminal with 'sudo mdutil -E /' or use SearchOnMac, which maintains its own independent on-device index.
