However, Apple users MUST be provided with Java patches at the same time as Windows users. Delaying Java patches for Mac users is NOT acceptable. I have verified that the direct download file, at least the current version from Apple, FAILs the Mac OS X 10.7 fsck check during file verification. The only way to update from Java 6 (1.6)—the last version supported by Apple—to Java 7 is by manually downloading and installing it from Oracle. And apparently few Mac users have done so.
Where possible, CVE IDs are used to reference the vulnerabilities for further information.

Sep 06, 2012 It is likely that most Mac users do not have Java, as it does not come pre-installed for you with OS X as it once did. Since OS X Lion arrived a year ago, installing Java on a Mac has been a manual opt-in process. It is also likely that besides a few web sites and an occasional piece of software you may want to run, you don’t really need Java. Jan 20, 2017 Description: Multiple vulnerabilities exist in Java 1.6.0_17, the most serious of which may allow an untrusted Java applet to execute arbitrary code outside the Java sandbox. Visiting a web page containing a maliciously crafted untrusted Java applet may lead to arbitrary code execution with the privileges of the current user.
Available for: Mac OS X v10.6.3, Mac OS X Server v10.6.3
Impact: Multiple vulnerabilities in Java 1.6.0_17
Description: Multiple vulnerabilities exist in Java 1.6.0_17, the most serious of which may allow an untrusted Java applet to execute arbitrary code outside the Java sandbox. Visiting a web page containing a maliciously crafted untrusted Java applet may lead to arbitrary code execution with the privileges of the current user. These issues are addressed by updating to Java version 1.6.0_20. Further information is available via the Sun Java website at http://www.oracle.com/technetwork/java/javase/releasenotes-136954.html
Java
CVE-ID: CVE-2010-0538
Available for: Mac OS X v10.6.3, Mac OS X Server v10.6.3
Impact: Visiting a web page containing a maliciously crafted untrusted Java applet may lead to an unexpected application termination or arbitrary code execution with the privileges of the current user
Description: An out of bounds memory access issue exists in the handling of mediaLibImage objects. Visiting a web page containing a maliciously crafted untrusted Java applet may lead to an unexpected application termination or arbitrary code execution with the privileges of the current user. This issue is addressed by preventing Java applets from using the com.sun.medialib.mlib package. This issue only affects the Mac OS X implementation of Java.

Java
CVE-ID: CVE-2010-0539
Available for: Mac OS X v10.6.3, Mac OS X Server v10.6.3
Impact: Visiting a web page containing a maliciously crafted untrusted Java applet may lead to an unexpected application termination or arbitrary code execution with the privileges of the current user
Description: A signedness issue exists in the handling of window drawing. Visiting a web page containing a maliciously crafted untrusted Java applet may lead to an unexpected application termination or arbitrary code execution with the privileges of the current user. This issue is addressed through improved bounds checking. This issue only affects the Mac OS X implementation of Java.

Installing the software
Windows
Make sure you have a recent Java JRE installed on your system. Gephi is compatible with Java 7 and 8 versions. Download Free Java here.
After the download completes, run the installer and follow the steps.
Mac OS X
After the download completes, click on the downloaded .dmg file.
Drag the gephi application in your Application folder.
Linux
Update your distribution with the last official JRE 7 ir 8 packages.
After the download completes, unzip and untar the file in a directory.
Run it by executing ./bin/gephi script file.
Troubleshooting
Java For Mac Users Manual
Java 7 standard edition or newer required
Check you have Java properly installed on your system. If you're on Linux, you may provide the path to the jdk with ./bin/gephi --jdkhome $JAVA_HOME
JVM Creation failed
This error message is due to memory settings, see following section.
Memory
Memory available to Gephi is determined by Java. Less or more memory can be allocated by configuring Gephi’s startup settings. If too less memory is allocated, Gephi will stop running when it reached the limit and you will loose your current work. If more memory than what the system is equipped with is set, Java will not be able to start and return “JVM Creation failed” message. By default, maximum memory is set to 512mo.
To modify memory settings, you need to edit gephi settings file. Modify the value after the -Xmx option to change the maximum heap space. For example, to use a heap size between 256 and 1024 MB, change the options to -Xms256m and -Xmx1024m. If you have Gephi open, you must close and reopen Gephi before new options take effect. On computers with 2GB of memory, you can set -Xmx1400 to get maximum performance.
Java Download For Mac
How to edit gephi.conf:
On Windows, go to the Gephi folder in Start menu and click on Startup Settings. Edit this file with Notepad or WordPad. Alternatively, go in C:Program Files (x86)Gephi 0.9etcgephi.conf and edit file manually.
On Mac OS X, right-click on Gephi application icon and select Show Package Contents to open a new Finder window displaying a Contents folder. Open the Contents folder, and then open the Resources/gephi/etc folder, in which the gephi.conf file resides. Use TextEdit to edit the file.
On Linux, go into your application directory and then into the etc folder. Edit the file with a text editor.
Java For Mac Pro
When multiple JRE or JDK are installed on the same machine, you can specifty to Gephi to use a particular path. Edit gephi.conf as described in the upper section, uncomment the jdkhome line and set the JRE or JDK path.
User files
Locate and delete gephi user directory to clean your installation.
On Windows 2K/XP, user diretory is located in C:Documents and SettingsusernameApplication Data.gephi
On Windows Vista/Seven/8/10, user directory is located in C:UsersusernameAppDataRoaming.gephi
On Mac OS X, user directory is located in /Users/username/Library/Application Support/gephi
On Linux, user diretory is located in /home/username/.gephi
