Microsoft provides a keyboard mapping article that describes using a Windows keyboard with macOS. Use Microsoft Keyboard Layout Creator to find key combinations for the unique characters used by the language and region your Apple keyboard is designed to support: Download, install, and open the Microsoft Keyboard Layout Creator. I remember from a third party keyboard i used to have that unless I installed their driver, modifier keys did not work. At some point, they no longer issued updates, so none of those keys would work with a newer OS version. On their site, they claim to be compatible to 10.11.4. Which OS version are you running (you do NOT have iOS on a Mac).

Executive Summary

Microsoft is announcing the availability of an update to improve input filtering for certain Microsoft wireless mouse devices. The update enhances security by filtering out QWERTY key packets in keystroke communications issued from receiving USB wireless dongles to wireless mouse devices. This improvement is part of ongoing efforts to improve the effectiveness of security in Windows and Microsoft devices. For more information, see Microsoft Knowledge Base Article 3152550.

A vulnerability has been discovered that allows keyboard HID packets to be injected into Microsoft wireless mouse devices through USB dongles. USB dongles will accept keyboard HID packets transmitted to the RF addresses of wireless mouse devices.

Recommendation

Microsoft recommends installing a filter driver available as an optional update for customers who use wireless mouse devices affected by this vulnerability. For the list of affected devices, see the Affected Devices section. For more information about affected operating systems, see the Affected Software section.

Microsoft recommends that customers test any new settings prior to implementation in their environments. Please see the Suggested Actions section of this advisory for more information.

Advisory FAQ ------------

What is the scope of the advisory?
The purpose of this advisory is to notify customers that an update is available to improve input filtering for affected Microsoft wireless mouse devices. The update enhances security by filtering out QWERTY key frames in communications issued from receiving USB wireless dongles to affected wireless mouse devices.

What causes the issue?
A vulnerability has been discovered that allows keyboard HID packets to be injected into Microsoft wireless mouse devices through USB dongles. USB dongles will accept keyboard HID packets transmitted to the RF addresses of affected wireless mouse devices.

What might an attacker use the vulnerability to do?
An attacker could use the vulnerability to inject arbitrary keyboard HID packets (for example, to simulate keystrokes) into a USB dongle.

How could an attacker exploit the vulnerability?
To exploit the vulnerability, an attacker could inject malicious commands into a victim’s computer through an attached USB dongle. The attack would require physical proximity to be in wireless range of the target computer. Note, however, that an attacker would not be able to sniff or recover plain text information, such as passwords, from encrypted sessions.

What does the update do?
The update enhances security by filtering out QWERTY key packets in communications issued from receiving USB wireless dongles to affected Microsoft wireless mouse devices. The update prevents dongles that are included with a standalone mouse from receiving keyboard-type signals.

I am using one of the devices listed in the Affected Devices table on an affected operating system. Why am I not receiving this update?
This security update supports only standalone mouse devices. Mouse devices sold as a keyboard and mouse Desktop package are not supported.

How can I determine if my mouse was originally part of a Desktop package?
For more information, see the steps in “How to determine if your mouse is standalone or part of a Desktop package” in the Other Information section.

Why does this update not service my keyboard and mouse Desktop package?
Applying this change to a dongle that is used for a keyboard and mouse Desktop package would prevent the normal reception of keystroke signals from the keyboard.

Suggested Actions

Apply the update for supported releases of Microsoft Windows
The optional update is available through Windows Update. If automatic updating is enabled, customers can install the update automatically. For more information about how to turn on automatic updating, please see Windows Update. Customers who have not enabled automatic updating need to check for updates and install this update manually. For information about specific configuration options in automatic updating, see Microsoft Knowledge Base Article 294871.
In some circumstances, customers who have enabled automatic updating may need to install this update manually, and can obtain the update from Microsoft Update Catalog. For more information on how to manually apply the update, see Microsoft Knowledge Base Article 3152550.
