A Mac can show the mouse in Bluetooth preferences and still fail at the last pairing screen, which is why the Logitech wireless M555b For Mac Mouse Driver page should start with discovery mode rather than a receiver check. This model connects through Bluetooth, uses a bottom Bluetooth connection button, and does not need a USB dongle for normal Mac setup.
The M555b for Mac is built around a direct Bluetooth connection, two main click buttons, a scroll wheel, an Application Switcher button, a battery and Bluetooth LED, an on and off switch, and a tilt wheel for horizontal scrolling. The top LED blinks blue during pairing and red when battery power runs low, so it gives useful clues before any software change is needed.

Mouse appears, then pairing fails
Put the mouse into discovery again before deleting every input preference on the Mac. Turn the mouse on, press the Bluetooth connection button on the underside, and wait for the blue light to blink. Then open Bluetooth preferences and add the device from there instead of trying to connect from an old saved entry.
If the Mac asks for a passkey, use 0000. That small detail matters on older Bluetooth setup screens because the pairing window may not explain what code the mouse expects. After the Mac accepts the code, move the mouse for a few seconds before opening another app, because the first pointer response may not be instant.
Old Bluetooth entry blocks a new pairing
When the M555b was used with the same Mac before, the saved Bluetooth record can prevent a fresh handshake. Remove the old mouse entry from Bluetooth preferences, turn Bluetooth off and back on, restart the mouse, and pair again from discovery mode. Keeping the old entry while pressing the connect button often sends the Mac back into the same failed loop.
Mac Sleep, Wake, and Bluetooth Dropouts
The Logitech wireless M555b For Mac Mouse Driver is most useful when the Mac sees Bluetooth devices but the M555b drops after sleep, battery replacement, or a system update. In that case, the problem is usually a stale Bluetooth session or weak power at the mouse, not a missing USB driver.
After waking the Mac, give the mouse a short moment before pressing the connect button repeatedly. Move it once, click once, and check whether Bluetooth preferences still shows it as connected. If the pointer does not return, switch the mouse off, wait briefly, switch it on again, and only then reopen Bluetooth preferences.
Mouse vanishes after the Mac wakes
A sleep dropout can become worse after macOS changes because the Bluetooth stack keeps an older device state. Remove the M555b from the Bluetooth list, restart the Mac, and pair it again while the blue LED is blinking. This is usually cleaner than leaving three failed connection attempts in the device list.
If other Bluetooth accessories also act strangely, reset the Mac’s Bluetooth connection before blaming the mouse. Turn Bluetooth off, wait, turn it on again, and then reconnect the M555b. On older Mac systems, a Bluetooth preference reset may be needed when every paired device starts reconnecting slowly after an update.
Red light or no light after battery change
The red LED is a battery warning, but a new battery set can still fail if the cells sit loosely or face the wrong way. Open the battery door, check the installation marks, and make sure both batteries press firmly against the contacts. Close the door fully before testing pairing again.
Do not judge the batteries only by whether another low-power device accepts them. Bluetooth discovery can fail during the short pairing burst if the voltage drops under load. A clean battery compartment and a firm fit can fix a mouse that looks visible for a second and then disappears.
Scroll Wheel Modes Can Make the M555b Feel Broken
The M555b has a wheel that can switch between Hyperfast scrolling and click-to-click scrolling by pressing and releasing the wheel. That feature is useful, but it also creates confusion. A page that suddenly flies too far, or a wheel that feels too slow, may simply be in the other scrolling mode.
Press and release the wheel once, then test the same page again. Do not hold it down as though you are middle-clicking a link. The action changes the wheel mode, so a quick press can bring back the stepped scrolling feel or restore fast movement through long documents.
Wheel press does not behave like middle click
Because the wheel press also changes scrolling behavior, some people expect it to work like a normal middle button in every app and then think the driver failed. Test the action in a browser, a document, and the app where the problem started. If only one app responds differently, the app is deciding how to treat the wheel press.
Horizontal scrolling is missing
The M555b includes tilt-wheel horizontal scrolling, but the result depends on the program in front of you. Spreadsheets, wide documents, timelines, and image editors may respond, while some web pages or plain text boxes may ignore the tilt movement. Test it in a wide sheet before changing the Logitech wireless M555b For Mac Mouse Driver package or Mac settings.
If horizontal movement works in one app and not another, leave Bluetooth pairing alone. The connection is already working. Check the application’s mouse or scrolling preferences instead, because the tilt signal may reach macOS while the active program chooses not to use it.
Application Switcher Button Opens the Wrong Thing
The button below the wheel is not a standard side button, and it should not be treated like a browser back button. On the M555b for Mac, the Application Switcher action can vary by application, and it may open a link in a new browser tab rather than switching windows in every situation.
For custom shortcuts, use the Mac’s mouse or shortcut settings that are available for the device. Keep the test simple: try the button in a browser, then in another Mac app. If the action changes between apps, the button is being read, but the active software is assigning a different meaning to it.
Button works once and then stops in another program
App-specific behavior is common with this button. A browser may treat it as a tab action, while a design, office, or remote desktop app may ignore it or reserve it for another command. Do not re-pair the Bluetooth connection for that symptom unless pointer movement and normal clicks are also failing.
When the button is important for work, assign a shortcut that the target app already understands. Avoid stacking several mouse utilities or shortcut tools for the same button, because two control layers can fight each other and make the button seem random.
Tracking Trouble Without a Receiver to Move
Since this mouse has no USB receiver, pointer problems should be checked through surface, Bluetooth condition, and battery power. The M555b uses laser tracking, so it can handle many surfaces, but glossy desks, glass, uneven fabric, and reflective tables can still make the cursor hesitate or jump.
Test the mouse on a plain matte surface before changing Mac Bluetooth files. If movement becomes steady on paper or a mouse pad, keep that surface and leave the pairing alone. If the same delay follows the mouse everywhere, check battery power and reconnect Bluetooth from a fresh discovery attempt.
Pointer moves but feels delayed
A delayed pointer can come from Bluetooth congestion, especially near many wireless devices. Move the Mac and mouse away from crowded hubs, speakers, and other active Bluetooth accessories for a short test. Also close the Bluetooth preferences window after pairing, because repeated scanning can make troubleshooting feel worse than normal use.
The Logitech wireless M555b For Mac Mouse Driver should be used after these checks, not before them. Install or reload the Logitech support software only when Bluetooth pairing completes but Mac controls, wheel behavior, or button actions still do not match what the device can do.
Clicks work but motion skips across the screen
When clicks register but motion skips, the sensor is usually reading a bad surface or losing a steady tracking pattern. Clean the bottom sensor window with a dry soft cloth and test again on a dull surface. Avoid wet cleaning near the opening, because moisture can leave residue and make tracking worse.
Finish With the Mac Pairing State, Not a Receiver Search
A good M555b setup ends with one Bluetooth record, working batteries, the blue pairing light used only when adding the device, and the scroll mode set the way you prefer. There is no receiver to replace and no Unifying setup to chase, so the final check should stay focused on Mac Bluetooth, wheel mode, tilt scrolling, and the Application Switcher behavior.
If the mouse still fails after a clean Bluetooth pairing, fresh batteries, a safe surface, and a restart, test it on another Bluetooth-capable Mac if available. That separates a Mac Bluetooth problem from a failing mouse. For normal use, keep the Logitech wireless M555b For Mac Mouse Driver support files simple and avoid installing unrelated Logitech packages made for receiver-based or gaming devices.
