Dobrý den, v MacOS Tahoe mně nefunguje kolečko na posouvání. Nevíte jak to vyřešit? Nebo to je normální? V návodu jsem se dočetl, že u MacOS nefungují pouze boční tlačítka.


This wireless mouse features an integrated battery with up to 66 hours of battery life, quiet and durable main buttons, adjustable sensitivity, RGB backlighting with four modes, and three ways to connect (2× Bluetooth, 1x 2.4GHz and 1× USB), so it can be connected to up to four devices. However, the greatest benefit of the Eternico M400 is its vertical ergonomic shape, which supports the natural position of the hand and allows you to keep your wrist in a resting position—without effort, cramps, and unnecessary tension, even during long-term use. The result is significantly more comfort, less fatigue and a healthier way of working, which will be appreciated by anyone who spends most of their day at the computer. The mouse combines functionality, style and ergonomics in perfect balance, making it an indispensable part of your work equipment.


This 108g mouse has an integrated Li-ion battery (500mAh) that can be conveniently charged using the included USB-C cable, so you'll no longer have to worry about replacing batteries. The advantage is that you can charge the Eternico M400 vertical mouse in several ways—via a computer, laptop, power bank or a suitable mains adapter. The battery life is up to 23 hours with RGB backlighting on (up to 66 hours with the backlighting off). An indicator light will alert you when the battery is almost empty, and there's also an automatic power-saving mode that activates after a few minutes of inactivity.

You can connect the Eternico M400 wireless mouse to up to four devices in total. The package includes a miniature USB receiver (2.4GHz), which can be permanently left in the USB port of your desktop computer. This makes the mouse easy to transport without having to constantly unplug the receiver from the computer. You can then connect the mouse via Bluetooth to two other devices, such as a laptop. A standard connection via a USB-C cable is also available. If needed, you can store the receiver in the dedicated compartment on the bottom of the mouse.

You'll have a total of six buttons at your disposal, including a classic wheel, forward/back buttons, and a DPI change button. You can set the sensitivity of the Eternico M400's optical sensor to several levels—800/1,200 (default)/1,600/2,000/2,400DPI. The RGB backlighting, in the form of three thin strips on the side, has four lighting modes and can be turned off completely. The mouse is primarily suitable for office and home use. The mouse's range is 10 metres in 2.4GHz mode and 8 metres in Bluetooth mode.

Plug and Play means you don't need to install any special drivers—just plug the receiver into a free USB port or pair the mouse with your laptop, for example, and start using it right away. The right and left buttons are fitted with top-of-the-line silent switches with a lifespan of up to 3 million clicks—so the Eternico M400 vertical mouse is sure to last you for several years, even with heavy daily use.

When working with a conventional mouse, the wrist is not in an ideal position. The shape of the ergonomic, vertical Eternico M400 mouse is much more natural for the hand; the muscles are not strained or overstressed when gripping. The vertical design also allows for a comfortable thumb position on the side, providing easy and natural control of the forward and back buttons. It makes work more comfortable, and even after long hours, there is no risk of unpleasant pain. Using a vertical mouse also makes it easy to prevent a lot of problems, including unpleasant wrist pain or even carpal tunnel syndrome.
