В статье ниже рассматриваются следующие вопросы, касающиеся Bonjour: что это такое и что делает, можно ли удалить эту программу, как скачать и установить Bonjour (если потребовалось, что может внезапно случиться после её удаления).
О том, что за программа Bonjour в Windows, обнаруживаемая в «Программы и компоненты» Windows, а также в виде Bonjour Service (или «Служба Bonjour») в службах или как mDNSResponder.exe в процессах, то и дело спрашивают пользователи, причем большинство из них отчетливо помнят, что ничего подобного не устанавливали.
Помнится, и я, впервые столкнувшись с наличием Bonjour у себя на компьютере не мог взять в толк, откуда оно взялось и что это такое, ведь всегда очень внимателен к тому, что устанавливаю (и к тому, что пытаются установить мне в нагрузку).
Прежде всего, причин переживать нет: программа Bonjour — это не вирус или что-то подобное, а, как подсказывает нам Википедия (и так оно есть на самом деле), программный модуль для автоматического обнаружения сервисов и служб (а точнее — устройств и компьютеров в локальной сети), используемый в последних версиях операционной системы Apple OS X, реализация сетевого протокола Zeroconf. Но здесь остается вопрос о том, что эта программа делает в Windows и откуда она там взялась.
Для чего нужна программа Bonjour в Windows и откуда она берется
ПО Apple Bonjour, и соответствующие службы как правило попадают на компьютер при установке следующих продуктов:
- Apple iTunes для Windows
- Apple iCloud для Windows
То есть, если вы установили на компьютер что-то из перечисленного, в Windows автоматически появится и рассматриваемая программа.
При этом, если я не ошибаюсь, когда-то эта программа распространялась и с другими продуктами от Apple (кажется, впервые я с нею столкнулся несколько лет назад, после установки Quick Time, но сейчас Bonjour в комплекте не устанавливается, также эта программа была в комплекте браузера Safari для Windows, ныне не поддерживаемого).
Для чего нужна программа Apple Bonjour и что она делает:
- iTunes использует Bonjour для нахождения общей музыки (Home Sharing), устройств AirPort и работы с Apple TV.
- Дополнительные применения, указанные в справке Apple (которая по данной теме давно не обновлялась — https://support.apple.com/ru-ru/HT2250) включают в себя: обнаружение сетевых принтеров с поддержкой оповещений Bonjour, а также обнаружение веб-интерфейсов сетевых устройств с поддержкой Bonjour (в виде плагина для IE и как функция в Safari).
- Плюс к этому использовалось в Adobe Creative Suite 3 для обнаружения «служб управления сетевыми активами». Не знаю, используется ли текущих версиях Adobe СС и что такое «Службы управления сетевыми активами» в данном контексте, предполагаю, что имеются в виду либо сетевые хранилища, либо Adobe Version Cue.
Попробую пояснить всё то, что описано во втором пункте (не ручаюсь за точность). Насколько я смог понять, Bonjour, используя мультиплатформенный сетевой протокол Zeroconf (mDNS) вместо NetBIOS, обнаруживает сетевые устройства локальной сети с поддержкой этого протокола.
Это, в свою очередь, позволяет проще обращаться к ним, а при использовании плагина в браузере — быстрее заходить в настройки маршрутизаторов, принтеров и других устройств с веб-интерфейсом. Как именно это реализовано — не видел (из той информации, что нашел, все устройства и компьютеры Zeroconf доступны по адресу сетевое_имя.local вместо IP-адреса, а в плагинах, вероятно, как-то автоматизирован поиск и выбор этих устройств).
Можно ли удалить Bonjour и как это сделать
Да, вы можете удалить Bonjour с компьютера. Будет ли при этом все работать как раньше? Если вы не пользуетесь функциями, указанными выше (общий доступ к музыке по сети, Apple TV), то будет. Возможные проблемы — оповещения iTunes, что ему не хватает Bonjour, но обычно при этом все обычно используемые пользователями функции продолжают работать, т.е. скопировать музыку, сделать резервную копию вашего устройства Apple вы сможете.
Один спорный вопрос — будет ли работать синхронизация iPhone и iPad с iTunes по Wi-Fi. Тут я проверить, к сожалению, не могу, а найденная информация разнится: часть сведений говорит о том, что для этого Bonjour не обязателен, часть — о том, что если возникли проблемы с синхронизацией iTunes по Wi-Fi, то в первую очередь следует установить Bonjour. Второй вариант кажется более вероятным.
Теперь о том, как удалить программу Bonjour — так же, как и любую другую программу Windows:
- Зайдите в Панель управления — Программы и компоненты.
- Выберите Bonjour и нажмите «Удалить».
Здесь следует учитывать одну деталь: если Apple Software Update обновит iTunes или iCloud на вашем компьютере, то во время обновления у вас снова установится Bonjour.
Примечание: может быть так, что программа Bonjour на компьютере установлена, устройств iPhone, iPad или iPod у вас никогда не было, а программами Apple у себя на компьютере вы не пользуетесь. В этом случае можно предположить, что данное ПО попало к вам случайно (например, установил друг ребенка или подобная ситуация) и, если оно не требуется, просто удалите все программы Apple в «Программы и компоненты».
Как скачать и установить Bonjour
В ситуациях, когда вы удалили программу Bonjour, а после этого оказалось, что этот компонент необходим для тех функций, которыми вы пользовались в iTunes, на Apple TV или для печати на принтерах, подключенных к Airport, вы можете использовать один из следующих вариантов для повторной установки Bonjour:
- Удалить iTunes (iCloud) и снова установить, скачав с официального сайта https://support.apple.com/ru-ru/HT201352. Также можно просто установить iCloud, если у вас установлен iTunes и наоборот (т.е. если установлена лишь одна из этих программ).
- Можно скачать установщик iTunes или iCloud с официального сайта Apple, после чего распаковать этот установщик, например, с помощью WinRAR (кликнуть по установщику правой кнопкой мыши — «Открыть в WinRAR». Внутри архива вы найдете файл Bonjour.msi или Bonjourmsi — это и есть отдельный установщик Bonjour, который можно использовать для установки.
На этом задачу по объяснению, что представляет собой программа Bonjour на компьютере с Windows считаю выполненной. Но, если вдруг возникнут вопросы — спрашивайте, постараюсь ответить.
Uninstalling and then reinstalling iTunes should also reinstall Bonjour.
For the reinstall, use an installer downloaded from the Apple website:
http://www.apple.com/itunes/download/
… or you could get it back via your Apple Software Update for Windows.
If you’d prefer not to uninstall iTunes, try the following procedure.
Download and save a copy of the iTunesSetup.exe (or iTunes64setup.exe) installer file to your hard drive:
http://www.apple.com/itunes/download/
Download and install the free trial version of WinRAR:
http://www.rarlab.com/
Right-click the iTunesSetup.exe (or iTunes64setup.exe), and select «Extract to iTunesSetup» (or «Extract to iTunes64Setup»). WinRAR will expand the contents of the file into a folder called «iTunesSetup» (or «iTunes64Setup»).
Go into the folder and doubleclick the Bonjour.msi (or Bonjour64.msi) to do a standalone Bonjour install.
Bonjour is a technology developed by Apple that automatically detects computers, services and equipment connected to local networks. Bonjour refers to Zero Configuration Networking, a set of technologies used to create IP networks that do not require configuration and installation of supporting servers. With Bonjour, devices on the network can detect each other without using either IP addresses or DNS servers. Bonjour includes a print wizard, system service and a plugin for Internet Explorer that allows you to find local web servers. Bonjour sends and receives packets via the UDP protocol (port 5353) — so if you use a firewall, you may need to open this port. The Bonjour system service runs in the background, monitoring network requests and caching the list of devices connected to the network. This allows you to quickly (almost instantly) find network devices and services. With Bonjour you can also print documents over the network.
Bonjour allows instant detection of devices and services on the same network without the need for IP addresses or DNS servers, simplifying network setup.

Bonjour is a software program, which was initially created by the Apple company. One of the main functionalities of the Bonjour software program is to allow for zero configuration between various types of devices. It allows for devices being run by both Apple & Windows to run, connect, & share resources without the need for settings configurations. Bonjour for Windows runs the software just as seamlessly as it is run for Apple.

This is a technology signed by Apple that automatically detects computers, services, and devices connected to local networks. Its existence is based on the principle of zero-configuration networks, promoting the creation of IP networks without requiring configuration or installation of support servers. With this technology, network devices can discover each other without the need for using IP addresses or DNS servers. It includes a printing assistant, a system service, and a plugin for Internet Explorer to identify local web servers. Additionally, it manages the transmission and reception of packets via the UDP protocol (port 5353). Don’t forget, if you use a firewall, it may be necessary to open this port. This system service works in the background, monitors network requests, and caches the list of devices connected to the network, facilitating quick search for devices and services on the network. And as a bonus, it allows printing documents via the network.
Bonjour is Apple’s implementation of zero-configuration networking (zeroconf), a group of technologies that includes service discovery, address assignment, and hostname resolution. Bonjour locates devices such as printers, other computers, and the services that those devices offer on a local network using multicast Domain Name System (mDNS) service records.

The software comes built-in with Apple’s macOS and iOS operating systems. Bonjour can also be installed onto computers running Microsoft Windows. Bonjour components may also be included within other software such as iTunes and Safari.
It was originally introduced in 2002 with Mac OS X 10.2 with the name Rendezvous. It was renamed in 2005 to Bonjour following an out-of-court trademark dispute settlement.[1][2]
Bonjour provides a general method to discover services on a local area network. The software is widely used throughout macOS, and allows users to set up a network without any configuration. As of 2010 it is used to find printers and file-sharing servers.
Notable applications using Bonjour include:
- iTunes to find shared music
- iPhoto to find shared photos
- Adium, Pidgin, Vine Server, and Elgato EyeTV to communicate with multiple clients
- SubEthaEdit to find document collaborators
- Solidworks and PhotoView 360 to manage licenses
- Things and OmniFocus to synchronize projects and tasks across the Mac desktop and the iPad, iPhone or iPod touch
- Safari to find local web servers and configuration pages for local devices
Software such as Bonjour Browser or iStumbler, both for macOS, can be used to view all services declared by these applications. Apple’s «Remote» application for iPhone and iPod Touch also uses Bonjour to establish connection to iTunes libraries via Wi-Fi.[3]
Bonjour only works within a single broadcast domain, which is usually a small area, without special DNS configuration. macOS, Bonjour for Windows and AirPort Base Stations may be configured to use Wide Area Bonjour which allows for wide area service discovery via an appropriately configured DNS server.
Applications generally implement Bonjour services using standard TCP/IP calls, rather than in the operating system. Although macOS provides various Bonjour services, Bonjour also works on other operating systems. Apple has made the source code of the Bonjour multicast DNS responder, the core component of service discovery, available as a Darwin open source project. The project provides source code to build the responder daemon for a wide range of platforms, including Mac OS 9, macOS, Linux, *BSD, Solaris, VxWorks, and Windows. Apple also provides a user-installable set of services called Bonjour for Windows and Java libraries.
Bonjour is released under a terms-of-limited-use license by Apple. It is freeware for clients, though developers and software companies who wish to redistribute it as part of a software package or use the Bonjour logo may need a licensing agreement. The source code for mDNSResponder is available under the Apache License.[4]
Apple originally introduced the Bonjour software in August 2002 as part of Mac OS X 10.2 under the name «Rendezvous». On August 27, 2003 Tibco Software Inc announced that it had filed a lawsuit for trademark infringement.[5]
Tibco had an enterprise application integration product called TIBCO Rendezvous on the market since 1994 and stated that it had tried to come to an agreement with Apple Computer. In July 2004 Apple Computer and Tibco reached an out-of-court settlement;[6] specifics of the settlement were not released to the public. On April 12, 2005, Apple announced the renaming of Rendezvous to «Bonjour».[1]
The current name Bonjour is French for the morning or afternoon greeting, «good day». The previous name Rendezvous is French for «meeting», «appointment» or «date».[7]
Other implementations
edit
Bonjour version 2.0, released on February 24, 2010, works with Microsoft Windows 2000, 2003, XP, Vista, 7, 8, 8.1, 10, and 11.[8] Systems use it primarily to facilitate the installation, configuration, and use of network printers, and thus it runs from startup. When Bonjour is fully implemented on Windows, some features—such as iChat—allow for communication between Windows and Mac OS. Bonjour for Windows also adds zeroconf capabilities to Internet Explorer, and provides a zeroconf implementation to Java VMs.[8][9]
Some third-party applications, such as Adobe’s Photoshop CS3 suite,[10]
also come bundled with Bonjour to take advantage of zeroconf technology.
Installers on Windows systems normally place Bonjour files in a folder called «Bonjour» within the «Program Files» folder. It modifies Windows system-registry entries related to internal network configuration and operation. Bonjour runs as mDNSResponder.exe. Communications across the network take place over UDP port 5353, which may require reconfiguring some personal or corporate firewalls that block Bonjour packets. A full installation of Bonjour for Windows will include a plug-in for Internet Explorer, a printer wizard, and the network communication services. Not all components are included when installed as part of a third-party application or as a component of other Apple software such as iTunes.
Some VPN clients are configured so that local network services are unavailable to a computer when VPN software is active and connected.[8] In such a case no local zeroconf services are available to Bonjour or any other zeroconf implementation.
In September 2008, two security vulnerabilities were found in Bonjour for Windows.[11]
Certain installations of Bonjour for Windows lack an uninstaller and do not display a human-readable entry in the Windows services listing.[12]
In 32- and 64-bit releases of Windows 7, some older but still available versions of Bonjour services can disable all network connectivity by adding an entry of 0.0.0.0 as the default gateway. This was a bug reported in 2013.[13]
The open-source IM clients Pidgin, Kopete and Adium support the Bonjour IM protocol, as does the closed-source Trillian client.
A number of browsers allow an end-user to graphically explore the devices found using Bonjour.
Discovery / Bonjour Browser
edit
Discovery is a Creative Commons-licensed macOS application that displays all services declared using Bonjour. The program was originally called Rendezvous Browser, but changed its name in version 1.5.4 after Apple changed the protocol’s name to Bonjour; since version 2.0, it has been renamed again, to Discovery. For certain protocols, double-clicking a list item will launch the associated helper. Version 1.5.6 was the first universal binary release.
Future versions will allow users to completely define a service, instead of relying on the author to do so.
Bonjour Browser was recommended for service discovery in MacAddict #123.
Discovery is available on the Apple App Store.[14]
A student research project at Columbia University produced a Java-based system to match the functionality of Bonjour Browser, called JBonjourBrowser. JBonjourBrowser is open-source and available under the GPL.
JBonjourBrowser was built to emulate the functionality of Bonjour Browser, and at the same time work on multiple platforms. It requires Apple’s Bonjour Java library to run.
Bonjour Browser for Windows
edit
A native Windows application offers similar functions to Bonjour Browser for Mac OS. Bonjour Browser for Windows is offered for free by Hobbyist Software and HandyDev Software.
A commercial implementation called mDNSBrowser is offered by Netputing Systems Inc.
- Avahi – LGPL implementation
- AirPrint – Apple IPP-based print stack that uses Bonjour
- .local
- PostgreSQL – database supports Bonjour
- Service Location Protocol
- Bonjour Sleep Proxy service[15]
- Universal Plug and Play – provides discovery functionality similar to Bonjour among other things
- WS-Discovery – a technical specification that defines a multicast discovery protocol to locate services on a local network.
