Mac is a popular OS that keeps coming up with new updates to improve the user experience. Mojave is the newest update.
Apple has released macOS Catalina 10.15.4 to the public. With this update, iCloud Drive folder sharing is now on the Mac, as are Apple Music time-synced lyrics. Communication limits are now present in Screen Time for Mac as well, and there are a number of other improvments to be found in the update. Also, OS X Mountain Lion takes up about 10 GB of space on its initial installation, so the computer where you install Mac OS X must have at least 10 GB of space in its hard drive. However, that's only the bare minimum; if you plan to install Mac OS X for day-to-day use, I recommend allocating at least 50 GB of space.
The latest benefits of the Mac OS
You will get some handy benefits free of charge. Besides the obvious advantages, there are covert improvements that will boost your Mac.
If you’re a user of Mac OS, upgrading to the Mojave version is the logical next step. The only thing you should worry about is to update your apps, as the old versions won’t work on Mojave.
The most significant changes in the newest version relate to aesthetics. With Mojave, you can mute the colors of the interface, so you don’t find yourself blinded when working at night thanks to the Dark Mode. Furthermore, the Dynamic Desktop feature changes the image on your desktop to match the time of the day.
As an operating system, Mac OS has always tried to make things sleek and minimalist on your desktop. However, in the older versions, the sync between Mac and iPhone led to a lot of clutter. To counter that, Apple added Desktop Stacks to make your desktop organized according to the criteria you desire.
These, and many more features allow Mac users to enjoy an even sleeker operating system. Another thing that draws attention is an improvement in Continuity - the connection between the phone and the computer. In general, the newest version of the operating system brings everything the users loved in the previous versions - only enhanced.
Is there a better alternative?
No. Unless you rely too heavily on old apps without new updates, Mojave is a logical extension of your current user experience.

Where can you run this program?
Mac Mojave runs on Mac computers featuring an OS X 10.8 and later versions.
This new update took the best features and improved them. There are no obvious drawbacks, Mojave does its job, and it does it properly.
Should you download it?
Yes. If you're a Mac lover, you'll probably want to get OS X Mojave.

Nmap has supported Mac OS X since 2001, and our support has only improved over time. While Mac users can compile Nmap themselves, we also offer an executable installer. Nmap makes use of Jhbuild and gtk-mac-bundler which are used to build other projects for Mac OS X, such as OpenSSL, libapr, libsvn... Nmap is also available through systems such as MacPorts and Fink which package Unix software for Mac OS X.
The easiest way to install Nmap and Zenmap on Mac OS X is to useour installer. TheMac OS X section ofthe Nmap download page provides a file named
<version> is the version number of the mostrecent release. The
.dmgfile is known as a“disk image”. Installation instructions follow:
Download the file
nmap-.Double-click the icon to open it. (Depending on how you downloaded thefile, it may be opened automatically.)
The contents of the disk image will be displayed. One ofthe files will be a Mac meta-package file named
nmap-.Open it to start the installer.
On OS X 10.8 and later, you may see a dialog likeFigure 2.2.
Figure 2.2. Apple Gatekeeper block screen
If this happens, it is necessary to right-click or control-click on the
.mpkgand select “Open”,as shown inFigure 2.3.
Figure 2.3. Apple Gatekeeper Open menu
A dialog similar to the first will appear, this time having an“Open” button (shown inFigure 2.4).Click the button to continue.

Follow the instructions in theinstaller. You will be asked for your password since Nmap installs in a system directory.
Once the installer is finished, eject the disk image bycontrol-clicking on its icon and selecting“Eject”. The disk image may now be placed inthe trash.
See the instructions in the section called “Executing Nmap on Mac OS X” forhelp on running Nmap and Zenmap after they are installed.
The programs installed by the installer will run on Intel Mac OS X 10.5(Leopard) or later. Users of earlier versions will have to compile fromsource or use a third-party package. Instructions for PowerPC (PPC) Mac systems (which Apple ceased selling in 2006) are available on our wiki.
Compiling Nmap from source on Mac OS X is no more difficult thanon other platforms once a proper build environment is in place.
Compiling Nmap on Mac OS X requiresXcode,Apple's developer tools that include GCC and the rest of the usual buildsystem. Xcode is not installed by default, but can be downloaded free ofcharge from the Mac AppStore. After installing Xcode, open“Preferences”, select the“Downloads” tab, and click the“Install” next to “Command LineTools”.
Xcode installations don't always include the command line tools. You can install them by opening Xcode from the Applications folder, opening Preferencechoosing the
Download header icon and clicking the
Install button next to “Command Line Tools”.
Once you have installed Xcode and the command-line tools, follow the compilation instructions found in the section called “Linux/Unix Compilation and Installation from Source Code”. Note that on some older versions of Mac OS X, you may have to replace the command ./configure with ./configure CPP=/usr/bin/cpp. Also, on some newer Mac OS X versions, the libpcap version of the library provided by Apple may be too old. You may have to configure Nmap with the command ./configure --with-libpcap=included in order to use the compatible version included in Nmap, or you should update the libpcap installed on your machine.
Zenmap depends on some external libraries that do not come withMac OS X, including GTK+ and PyGTK. These libraries have many dependenciesof their own. A convenient way to install all of them is to use athird-party packaging system as described inSection . Once the dependencies areinstalled, follow the instructions in the section called “Linux/Unix Compilation and Installation from Source Code” toinstall Zenmap as usual.
Another option for installing Nmap is to use a systemwhich packages Unix software for Mac OS X. The two discussed here areFink andMacPorts. See therespective projects' web sites for how to install the packagemanagers.
To install using Fink, run the command fink installnmap. Nmap will be installed as
/sw/bin/nmap. To uninstall use the commandfink remove nmap.
To install using MacPorts, run sudo portinstall nmap. Nmap will be installed as
/opt/local/bin/nmap. To uninstall, runsudo port uninstall nmap.
These systems install the
nmapexecutable outside the global
PATH. To enable Zenmap tofind it, set the
nmap_command_path variable in
/opt/local/bin/nmap as described inthe section called “The
The terminal emulator in Mac OS X is calledTerminal, and is located in the directory
/Applications/Utilities. Open it and aterminal window appears. This is where you will type your commands.
