You're halfway through a massive report. You go to highlight a paragraph to move it, but nothing happens. Your cursor blinks mockingly. You click, you drag, you double-click, and yet the highlight won't stick. It’s infuriating. When Mac Microsoft Word can't select text, it basically turns your productivity suite into a very expensive digital paperweight. This isn't just a "you" problem; it's a documented ghost in the machine that has haunted macOS users across Sequoia, Sonoma, and Ventura.
Honestly, it's usually not your mouse. It’s rarely your trackpad. Most of the time, it’s a breakdown in how Word communicates with the macOS clipboard or a specific background process that has decided to hang.
The "Invisible Selection" Mystery
Sometimes the text is actually selected, but Word isn't showing you the gray or blue highlight. This is a classic graphical glitch. If you hit Command + C and paste it elsewhere, the text appears. But who can work like that? You need to see what you're doing. This often stems from a conflict with the Microsoft Word Cache.
Macs handle memory differently than PCs. When Word has been open for three days straight, its temporary cache files get bloated. They start tripping over themselves. You might find that the "can't select" issue starts subtly—maybe you can select a word but not a line—and then it just stops working entirely.
Quick Fixes That Actually Work
Before you reinstall the whole Office 365 suite, try the "Esc" trick. It sounds too simple to be true. Tap the Esc key three or four times rapidly. For some reason, this forces Word to reset its current focus state. If a hidden dialog box or a "ghost" menu is holding the cursor hostage, this usually snaps it out of it.
If that fails, look at your Select All command. Hit Command + A. Does the whole document turn blue? If it does, try clicking back into the text. Often, forcing a global selection "wakes up" the selection engine. It’s a bit like jump-starting a car.
The Role of macOS "Universal Control"
If you're using an iPad next to your Mac, or another Mac via Universal Control, things get weird. Apple’s seamless cursor movement is amazing until it isn't. Sometimes the "handshake" between the devices leaves the cursor in a state where Word thinks it's still being controlled by an external input.
Try turning off Handoff or Universal Control in System Settings for a moment. If the selection ability immediately returns, you've found your culprit. It's a known bug where the "focus" of the mouse gets stuck between the Mac's screen and the virtual edge of the secondary device.
Dealing with the "Trackpad Drag" Failure
Check your Accessibility settings. Go to System Settings > Accessibility > Pointer Control. Click on Trackpad Options. If you have "Use trackpad for dragging" enabled with "Three-finger drag," this occasionally clashes with Word’s internal logic.
Microsoft Word has its own proprietary way of handling click-and-drag. It’s not using the native macOS selection engine entirely; it’s a cross-platform port. Sometimes, turning off the three-finger drag and reverting to a standard "Click and Drag" solves the Mac Microsoft Word can't select text nightmare instantly.
The Nuclear Option: Deleting Plist Files
When the settings themselves are corrupted, no amount of restarting the app will help. You have to go into the Library.
- Quit Word completely. Make sure it's not lingering in the Dock.
- Open Finder, hold the Option key, and click Go > Library in the top menu bar.
- Navigate to
Containers > com.microsoft.Word > Data > Library > Preferences. - Find the file named
com.microsoft.Word.plist. - Drag it to the Trash.
When you restart Word, it will feel like the first time you opened it. It generates a fresh preference file. You might have to fix your custom toolbar again, but you’ll finally be able to select your text.
Third-Party App Interference
Are you using a clipboard manager like CopyClip or Pastebot? What about a window manager like Magnet or Rectangle?
These apps "hook" into your mouse movements and keyboard shortcuts. Sometimes they intercept the "Click-Hold-Move" gesture that Word relies on for selection. Try quitting these utility apps one by one. If Word suddenly starts behaving, you need to add Word to the "Ignore" or "Exclusion" list in that specific app's settings.

When It’s a "Protected View" Issue
If you downloaded the file from an email or Slack, Word might be opening it in a restricted mode. Usually, there's a yellow bar at the top, but sometimes that bar fails to load. You're looking at the document, but you're essentially in a "Read Only" ghost zone.
Check the very top of the window next to the document name. If it says (Read-Only) or [Protected View], you can't select or edit easily. You’ll need to save a copy locally (Command + S) to your desktop to regain full control.
A Note on "Focus Mode" and Full Screen
Microsoft Word's "Focus" mode is great for writing, but it’s buggy on macOS. If you are in Focus mode and your cursor disappears or won't highlight, exit back to the standard Print Layout view. The graphical overlay for Focus mode sometimes detaches from the actual text layer, meaning you’re clicking where the text looks like it is, but the app thinks the text is three pixels to the left.
Actionable Next Steps to Resolve the Issue
To get back to work immediately, follow this specific sequence:
- Force Quit and Clear: Don't just close Word; hit Command + Option + Esc and kill the process. Then, restart your Mac. A simple restart clears the NVRAM and resets the clipboard daemon (
pboard) which is often the silent killer of text selection. - Update the App: Open the Microsoft AutoUpdate tool. Microsoft pushes "Quality Improvements" monthly that specifically target these macOS-specific UI bugs. If you’re on version 16.xx and there’s an update, take it.
- Safe Mode Test: Restart your Mac and hold the Shift key to enter Safe Mode. This disables third-party drivers. If Word works perfectly in Safe Mode, you know for a fact that another app (like a mouse driver or a grammar checker) is interfering with your selection tool.
- Check for Overlays: Disable any apps that draw on your screen, like screen recorders (Loom) or color pickers. These create an invisible "layer" over Word that intercepts your clicks.
The Mac Microsoft Word can't select text bug is usually a software conflict rather than a hardware failure. By clearing the com.microsoft.Word.plist and ensuring no clipboard managers are interfering, you can usually restore functionality without having to reinstall your entire operating system.
