Open Source Free Download For Mac

Common Questions

How do I know if my project is open source?
Open source software is software with source code that anyone can inspect, modify and enhance. These projects are intended to promote collaboration and sharing because they encourage computer programmers to access, view and modify open source software whenever they like, as long as they let others do the same when they share their work. Find out more here.
I manage an open source project, but our software is not free. Can I still get access to this offer?
Unfortunately, no. This offer is only available to free open source developers.
I manage a free open source project, but we charge users for software services and support. Can I still get access to this offer?
Yes! As long as the software itself is free to use, you qualify for this offer.

I am a free, open source developer working on multiple projects. Can I receive a Mac mini for each of my projects?
Unfortunately, there can only be one registered Mac mini per user/project. If a manager for one of the other projects would like to apply for this offer, they are welcome to!
Where will the Mac mini be hosted?
We offer hosting of open source Mac minis where supply is available in our Atlanta, Las Vegas or Dublin locations. If you decide to purchase a private cloud or other product it can be hosted at any of our global data centers.
The Mac minis hosted out of the Dublin data center are priced slightly higher than Mac minis hosted out of the Las Vegas data center. Does this affect the discount or will I still receive a free Mac mini?
Yes, despite price differences, FOSS developers have access to a free Mac mini out of the Dublin data center.
I have a question that is not listed here... what do I do?
No problem! Our sales team is available via live chat or email us at [email protected] to answer any questions.

Downloading Nmap

Nmap and Zenmap (the graphical front end) are available inseveral versions and formats. Recent source releases and binarypackages are described below. Older version (and sometimes newer testreleases) are available from the dist directory(and really old ones are in dist-old).For the moresecurity-paranoid (smart) users, GPG detached signatures and SHA-1hashes for each release are available in the sigsdirectory (verification instructions). Before downloading, be sure to read the relevant sections for your platform from the Nmap Install Guide. The mostimportant changes (features, bugfixes, etc) in each Nmap version aredescribed in the Changelog. Using Nmap is covered in the Reference Guide, and don't forget to readthe other available documentation, particularly the new book Nmap Network Scanning!

Nmap is distributed with source code under custom license terms similar to (and derived from) the GNUGeneral Public License, as noted in the copyright page.

Microsoft Windows binaries

Open Source Free Download Manager

Please readthe Windows section of theInstall Guide for limitations and installation instructions for theWindows version of Nmap. You can choosefrom a self-installer (includes dependencies and also the Zenmap GUI)or the much smaller command-line zip file version. We support Nmap on Windows 7 and newer, as well as Windows Server 2008 and newer. We also maintain a guide for userswho must run Nmap on earlier Windows releases..

The Nmap executable Windows installer can handle Npcapinstallation, registry performance tweaks, and decompressing theexecutables and data files into your preferred location. It also includes the Zenmap graphical frontend. Skip all thecomplexity of the Windows zip files with a self-installer:

Latest stable release self-installer: nmap-7.91-setup.exe

We have written post-install usageinstructions. Please notify usif you encounter any problems or have suggestions for theinstaller.

For those who prefer the command-line zip files (Installation Instructions; UsageInstructions), they are still available. The Zenmap graphicalinterface is not included with these, so you need to runnmap.exe from a DOS/command window. Oryou can download and install a superior command shell such as thoseincluded with the free Cygwin system.Also, you need to run the Npcapand Microsoft Visual C++ 2013 Redistributable Packageinstallers which are included in the zip file. The main advantage is that these zip files are a fraction of the size of the executable installer:

Latest stable command-line zipfile:nmap-7.91-win32.zip

Linux RPM Source and Binaries

Many popular Linux distributions (Redhat, Mandrake, Suse, etc) usethe RPM package management system forquick and easy binary package installation. We havewritten a detailed guide toinstalling our RPM packages, though these simple commands usually dothe trick:You can also download and install the RPMs yourself:

Latest stable release:
x86-64 (64-bit Linux)Nmap RPM: nmap-7.91-1.x86_64.rpm
x86-64 (64-bit Linux)Ncat RPM: ncat-7.91-1.x86_64.rpm
x86-64 (64-bit Linux)Nping RPM: nping-0.7.91-1.x86_64.rpm
Optional Zenmap GUI (all platforms): zenmap-7.91-1.noarch.rpm
Source RPM (includes Nmap, Zenmap, Ncat, and Nping): nmap-7.91-1.src.rpm

Mac OS X Binaries

Nmap binaries for Mac OS X (Intel x86) are distributed as a disk image filecontaining an installer. The installer allows installing Nmap, Zenmap,Ncat, and Ndiff. The programs have been tested on Intel computersrunning Mac OS X 10.8 and later. See theMac OS X Nmap installpage for more details. Users of PowerPC (PPC) Mac machines, which Apple ceased selling in 2006, should see this page instead for support information.
Latest stable release installer: nmap-7.91.dmg

Source Code Distribution

This is the traditional compile-it-yourself format. The Nmaptarball compiles under Linux, Mac OS X, Windows, and many UNIXplatforms (Solaris, Free/Net/OpenBSD, etc.) It includes Zenmap, theGUI frontend.

Detailed Linux/BSD/Solaris compilation instructions and options are provided here, though this usually does the trick:

Most Windows users install with our Windows executable installer, but we also provide Windows source code compilation instructions.

Most Mac OS X users install with our Mac installer, but we also provide Mac OS X source code compilation instructions.

If you are compiling Nmap anyway, you might prefer to get the very latest code from our SVN source code repository rather than downloading a tarball here.

Other Operating Systems

Linux (all distributions)
Microsoft Windows
Mac OS X
FreeBSD, OpenBSD, and NetBSD
Sun Solaris
Amiga, HP-UX, and Other Platforms
