The Logitech Ultrathin Touch Mouse T631 is a slim Bluetooth touch mouse made for Mac users who want a small travel device with gesture control. It does not use a USB receiver, so the main connection comes through macOS Bluetooth pairing instead of a dongle-based driver.
macOS can handle basic pointer movement, clicking, and scrolling through its built-in Bluetooth mouse support. Logitech software adds the extra control layer for smoother touch gestures, button behavior, and mouse settings when the software version still matches the Mac system in use.
This model has a touch surface, left and right click zones, side-to-side scrolling, Bluetooth Easy-Switch channels, a Connect button, an on and off switch, and a rechargeable battery charged through a Micro-USB cable. If the mouse feels dead, jumpy, or missing gestures, check the Bluetooth channel and battery before blaming the download.

Pairing the T631 Without Treating It Like a USB Mouse
The T631 needs a Bluetooth pairing routine, not a receiver utility. Slide the Easy-Switch control to channel 1 or 2, turn the mouse on, and press the Connect button. The blue status light should blink quickly while the mouse stays discoverable for a short pairing window.
Choose the channel before opening Bluetooth settings
Pick one Easy-Switch channel for the Mac you are pairing. If you already paired the mouse with another Mac on channel 1, use channel 2 for the second computer. Changing channels after pairing can make the mouse look broken, even though it simply listens on the other saved connection.
Open Bluetooth settings on the Mac only after the light starts blinking. Select the Ultrathin Touch Mouse when it appears, then wait for the pairing to finish. If it does not appear, turn the mouse off, turn it on again, press Connect, and keep it close to the Mac during pairing.
Install software after the pointer already works
Do not start with Logitech software if the Mac has not paired the mouse yet. The download cannot fix a mouse that never entered Bluetooth pairing mode. Get basic movement and clicking working first, then add the Logitech package if you need gesture tuning or touch behavior settings.
On newer macOS versions, mouse software may need permission in Privacy and Security settings before gestures and custom actions work properly. After installing the package, allow the helper components that control input behavior, then restart the Mac if the settings panel still does not detect the mouse.
Charge it before judging the connection
A blinking red light means the built-in battery needs charging. Connect the Micro-USB cable to the mouse and a computer USB port or USB power adapter. The green light should blink during charging and stop blinking when the charge finishes.
If the mouse has been unused for a long time, leave it charging before testing Bluetooth again. A tiny short charge can bring it back for quick use, but a deeper charge gives a fairer test when the mouse disconnects or fails to wake.
T631 Bluetooth, Touch Surface, Charging, and Gesture Fixes
The T631 usually fails in a few predictable places: Bluetooth pairing, the Easy-Switch channel, touch gesture handling, battery charge, or surface tracking. The fixes below avoid receiver steps because this model does not connect through a USB dongle.
The T631 does not appear in the Mac Bluetooth list
Turn the mouse off, slide Easy-Switch to the channel you want, then turn it on and press Connect. Watch for the fast blue blinking light. If the light does not blink, the mouse has not entered pairing mode, and the Mac will not find it.
Keep the mouse within a short distance of the Mac while pairing. Remove old entries for the same mouse from Bluetooth settings if they appear, then start pairing again. A stale saved device entry can block a clean new connection.
The mouse paired once but will not reconnect
Check the Easy-Switch channel before doing anything else. If the mouse paired on channel 1 but the switch now sits on channel 2, the Mac will wait for a device that is not talking to that saved channel. Move the switch back and wait a few seconds.
If the channel is right and the mouse still stays silent, remove it from the Bluetooth list and pair it again. Restarting the Mac after removal often clears a stuck Bluetooth session, especially after sleep, system updates, or repeated failed pairing attempts.
The pointer disconnects at random
Recharge the mouse until the green charging light stops blinking. Low battery power can make the Bluetooth link drop, even when the mouse wakes for a moment after you switch it off and on. A red status light is a clear sign to charge first.
Move the mouse closer to the Mac and reduce Bluetooth clutter around the desk. External drives, crowded USB devices, and other wireless gear can add interference. If the connection improves near the Mac, the problem is signal strength rather than the mouse driver.
The mouse works, but gestures do not respond
Basic cursor movement can work without the full Logitech control layer, but touch gestures often need the Logitech software and macOS permissions. Open the mouse software after pairing, then check that the system allows its helper service to control input features.
If gestures stopped after a macOS update, reinstall the current Logitech package that matches the system. Then restart the Mac. Do not keep several old Logitech utilities installed together, because older helper services can conflict with newer permission rules.
Scrolling feels missing or only works sometimes
The T631 scrolls through swipes on the touch surface, not through a physical wheel. Swipe with one finger and test in a simple browser page or Finder window. Some apps handle horizontal and vertical scrolling differently, so test more than one place before changing settings.
Clean the top touch surface with a dry, soft cloth. Moisture, oil, or dust can make swipes feel inconsistent. If Logitech software offers scroll direction or gesture options, return those choices to a normal setting and test again before adding custom behavior.
Right click opens the wrong action
The touch surface needs a clean click on the right side for secondary click. Lift the other finger completely off the surface before clicking. If another finger rests on top, the mouse may read the action as a left click or gesture instead.
Also check the Mac secondary click setting. If the system expects a different click style, the T631 can feel unreliable even when the switch is fine. Set secondary click again, then test on the desktop and inside a browser menu.
The charging light does not behave as expected
Use a known working Micro-USB cable and push it in firmly. A loose cable can touch enough to shift the mouse but not enough to charge it properly. Try a computer USB port and then a USB power adapter if the light does not blink green.
Check the Micro-USB port for lint or dirt before assuming battery failure. Do not scrape inside the port with metal. If the mouse only works while plugged in or loses charge quickly, the internal rechargeable battery may have aged beyond normal use.
The pointer jumps or drifts during small movements
Move the T631 to a matte surface, plain mouse pad, or sheet of white paper. Glossy desks, glass, and strong patterns can confuse the sensor. A touch mouse can feel like it has a driver fault when the sensor simply cannot read the surface cleanly.
Wipe the sensor window on the bottom with a dry cloth. Dust at the sensor opening can create skipping while clicks still work. After cleaning, test slow diagonal movement because that usually reveals tracking trouble quickly.
The mouse wakes slowly after sitting idle
A short pause after idle use can happen because the T631 saves power. Move it once or click lightly and give Bluetooth a moment to wake. If it wakes only after switching off and on, recharge it and test again near the Mac.
If wake problems started after a system update, remove the mouse from Bluetooth settings and pair it again on the same Easy-Switch channel. That rebuilds the saved Bluetooth connection without changing every other device on the Mac.
The mouse keeps pairing with the wrong computer
The two Easy-Switch channels store separate Bluetooth pairings. Use channel 1 for one Mac and channel 2 for another, then leave the switch on the channel for the machine you are using. Random channel changes make the mouse look like it has disappeared.
When you no longer use one paired computer, remove the T631 from that computer’s Bluetooth list. Then pair that channel again with the Mac you actually want. This avoids the mouse reconnecting to a nearby old device when both machines have Bluetooth on.
Clicking and dragging files feels unreliable
Keep one finger on the click area and avoid brushing the top surface with another finger while dragging. The T631 reads touches across the smooth surface, so accidental contact can interrupt a drag or turn the action into a gesture.
Lower the Mac double-click speed slightly if single clicks and drag starts feel rushed. Also test the same drag on a matte surface. If the pointer slips during drag, tracking surface and touch contact both deserve checking before reinstalling software.
Logitech software opens but does not detect the mouse
Confirm that the T631 already moves the pointer through Bluetooth. Then quit the Logitech utility, reopen it, and check macOS Privacy and Security permissions for input monitoring or accessibility control. Without those permissions, the utility may open but fail to manage the mouse.
If detection still fails, remove older Logitech mouse utilities and install only the package that matches the Mac system. Restart after installation. Older background services can keep running quietly and stop the newer settings app from seeing a Bluetooth mouse correctly.
