TeamViewer is one of the most popular remote access software that is commonly used to provide remote support because it is easy to use and comes with really powerful features such as file transfer, switch sides, conference call, VoIP, screen recording and etc. Other than that, TeamViewer also works on multiple operating systems where it allows you to control a Mac OS X system from a Windows computer.
You will need to download and install the “HOST” version of TeamViewer on the Mac computer that you want to remotely control. As for the Windows computer that will be controlling the Mac computer, simply download the TeamViewer full version, install and run it. Enter the ID followed by the password and you’re able to connect to the OS X machine. The ID will not change and always stay the same on the machine.
The TeamViewer Host options can be accessed by clicking on the TeamViewer icon at the menu bar and select Preferences. You can change your password, configure the voice, microphone and phone conferencing, access control and etc.
2. LogMeIn Free
LogMeIn Free allows you to conveniently remotely control a Mac computer running OS X from Windows through its web interface or the Firefox plugin. First you will need to create a free account, then login from the Mac computer and click the Add Computer button to download the LogMeIn Installer. After installation, you are able to access that computer from any other computer by logging in to LogMeIn. Do take note that the file transfer feature is disabled in the free version.
Although there are many versions of VNC which are mostly free, RealVNC targets the enterprise users by offering shareware version and cross platform support to Windows, Mac OS X, Linux, Solaris, HP-UX and AIX. Similarly to LogMeIn, the free version of RealVNC provides a very basic remote access feature without file transfer, chat, session encryption, optimized performance, printing and deployment tool. You can use other VNC viewer such as TightVNC and UltraVNC to access the RealVNC server.
