For many users, was the problem of access to the Internet without having to install an antivirus program, or many users without hesitation to link to send them spam or suspicious sites.At the end, the problems associated with viruses and Trojans.But the emergence of such problems the owners of computers from Apple operating system Mac OS X, it is practically impossible even for beginners.Since the operating system is designed on the basis of Unix (kernel Darwin, in accordance with the standard "POSIX"), it is much better protected against malicious software, familiar to most users than Windows.Therefore, almost no one from the user OS X does not install anti-virus software is not your computer - they simply do not need them!
first version of the Unix operating system was set up in 1969, when not using graphic displays and a variety of controllers for data entry.And the most advanced input device has a keyboard.Therefore, to increase the productivity of labor is widely used in various key combinations - so-called "hot keys".And modern version kept this feature.By using hot keys you can often perform certain actions much faster than using the mouse or trackpad.They are also used, and Mac OS X, this is their main list (http://osxh.ru/content/hotkey_mac_os_x)
settings of the operating system, as a rule, are stored in plain text files, but with the protection of the rights established and very often these fileshidden from the casual user.Look it in the control program terminal.app and there can also enable their display to the standard file manager Finder (http://osxh.ru/content/hidden_files_mac_os_x).
Since Unix was originally a multi-user and multi-tasking operating system, many server functions built into it initially.So, in a modern version of Mac OS X initially have a web server, ftp server, but since they do not need a lot of users, they are disabled by default.And those who need them, they can simply turn on the necessary commands in the terminal.There is a version of Mac OS X Server, which differs from the standard additional server management program improves and extends its server capabilities.
For those users who can not completely abandon the use of programs developed for Windows, there are special programs allowing to install Windows in a virtual environment and use on a single computer at the same time as the program developed for the Mac, as well as for Windows.The best known such programs - Parallels and VMware Fusion.
