## 1.2. System Requirements

The amount of resources Wireshark needs depends on your environment and on the size of the capture file you are analyzing. The values below should be fine for small to medium-sized capture files no more than a few hundred MB. Larger capture files will require more memory and disk space.

| Busy networks mean large captures
A busy network can produce huge capture files. Capturing on even a 100 megabit network can produce hundreds of megabytes of capture data in a short time. A computer with a fast processor, and lots of memory and disk space is always a good idea.

If Wireshark runs out of memory it will crash. See https://wiki.wireshark.org/KnownBugs/OutOfMemory for details and workarounds.

Although Wireshark uses a separate process to capture packets, the packet analysis is single-threaded and won’t benefit much from multi-core systems.

### 1.2.1. Microsoft Windows

Wireshark should support any version of Windows that is still within its extended support lifetime. At the time of writing this includes Windows 11, 10, Server 2022, Server 2019, and Server 2016. It also requires the following:

- The Universal C Runtime. This is included with Windows 10 and Windows Server 2019 and is installed automatically on earlier versions if Microsoft Windows Update is enabled. Otherwise you must install KB2999226 or KB3118401.
- Any modern 64-bit Intel or Arm processor.
- 500 MB available RAM. Larger capture files require more RAM.
- 500 MB available disk space. Capture files require additional disk space.
- Any modern display. 1280 × 1024 or higher resolution is recommended. Wireshark will make use of HiDPI or Retina resolutions if available. Power users will find multiple monitors useful.

- A supported network card for capturing

  - Ethernet. Any card supported by Windows should work. See the wiki pages on Ethernet capture and offloading for issues that may affect your environment.
  - 802.11. See the Wireshark wiki page. Capturing raw 802.11 information may be difficult without special equipment.
  - Other media. See https://wiki.wireshark.org/CaptureSetup/NetworkMedia.

Older versions of Windows which are outside Microsoft’s extended lifecycle support window are no longer supported. It is often difficult or impossible to support these systems due to circumstances beyond our control, such as third party libraries on which we depend or due to necessary features that are only present in newer versions of Windows such as hardened security or memory management.

- Wireshark 4.4 was the last release branch to officially support Windows 10, version 1607 and Windows Server 2016.
- Wireshark 4.0 was the last release branch to officially support Windows 8.1 and Windows Server 2012.
- Wireshark 3.6 was the last release branch to officially support 32-bit Windows.
- Wireshark 3.2 was the last release branch to officially support Windows 7 and Windows Server 2008 R2.
- Wireshark 2.2 was the last release branch to support Windows Vista and Windows Server 2008 sans R2
- Wireshark 1.12 was the last release branch to support Windows Server 2003.
- Wireshark 1.10 was the last release branch to officially support Windows XP.

See the Wireshark release lifecycle page for more details.

### 1.2.2. macOS

Wireshark supports macOS 11 and later. Similar to Windows, supported macOS versions depend on third party libraries and on Apple’s requirements.

- Wireshark 4.2 was the last release branch to support macOS 10.14.
- Wireshark 3.6 was the last release branch to support macOS 10.13.
- Wireshark 3.4 was the last release branch to support macOS 10.12.
- Wireshark 2.6 was the last release branch to support Mac OS X 10.6 and 10.7 and OS X 10.8 to 10.11.
- Wireshark 2.0 was the last release branch to support OS X on 32-bit Intel.
- Wireshark 1.8 was the last release branch to support Mac OS X on PowerPC.

See the Wireshark release lifecycle page for more details.

The system requirements should be comparable to the specifications listed above for Windows.

### 1.2.3. UNIX, Linux, and BSD

Wireshark runs on most UNIX and UNIX-like platforms including Linux and most BSD variants. The system requirements should be comparable to the specifications listed above for Windows.

Binary packages are available for most Unices and Linux distributions including the following platforms:

- Alpine Linux
- Arch Linux
- Canonical Ubuntu
- Debian GNU/Linux
- FreeBSD
- Gentoo Linux
- HP-UX
- NetBSD
- OpenPKG
- Oracle Solaris
- Red Hat Enterprise Linux / CentOS / Fedora

If a binary package is not available for your platform you can download the source and try to build it. Please report your experiences to wireshark-dev[AT]wireshark.org.
