Sandboxing blocks malicious code on Mac OS X Yosemite

The App Sandbox in OS X helps ensure that apps do only what they’re intended to do. App sandboxing isolates apps from the critical system components of your Mac, your data, and your other apps. Even if an app is compromised by malicious software, sandboxing automatically blocks it to keep your computer and your information safe. OS X delivers sandboxing protection in Safari by sandboxing the built-in PDF viewer and plug-ins such as Adobe Flash Player, Silverlight, QuickTime, and Oracle Java. And OS X sandboxes apps like the Mac App Store, Messages, Calendar, Contacts, Dictionary, Font Book, Photo Booth, Quick Look Previews, Notes, Reminders, Game Center, Mail, and FaceTime.

Runtime protections defend at the core.

The technically sophisticated runtime protections in OS X work at the very core of your Mac to help keep your system safe. Built right into the processor, the XD (execute disable) feature creates a strong wall between memory used for data and memory used for executable instructions. This protects against malware that attempts to trick the Mac into treating data the same way it treats a program in order to compromise your system. Address Space Layout Randomization (ASLR) changes the memory locations where different parts of an app are stored. This makes it difficult for an attacker to do harm by finding and reordering parts of an app to make it do something it wasn’t intended to do. OS X brings ASLR to the memory used by the kernel at the heart of the operating system, so the same defenses work at every level in your Mac.

More ways to keep your Mac safe.

While no system can be 100 percent immune from every threat, OS X lets you do even more to keep your information as safe as possible. You’ll find most of these additional security features in the Security & Privacy pane of System Preferences. Here are just a few of the things you can do:

• Turn on a firewall to prevent other machines from accessing services running on your Mac.
• Control access to your Mac by locking your screen after a period of inactivity.
• Set up secure file sharing.

• Securely delete outdated sensitive files with the Secure Empty Trash command.
• Use Password Assistant to create stronger passwords for local utilities like Users & Groups.
• Make sure you’re only running sharing services that you really need.

Blender is the Best Free Video Editing with 3D Animation on Mac

Blender 2.75a is the latest stable release from the Blender Foundation.
To download it, please select your platform and location. Blender is Free & Open Source Software

Blender 2.75a was released on July 8, 2015. Blender is becoming more and more a program that can do everything, whether it is 3D or 2D. On the downside of that is the ever lengthening learning curve, because the more that is added, the more complex it becomes. That said, there is no other application I have seen that can do as much as Blender. But with new builds being released on average every two months, it is a program no-one will ever fully learn, at least until it become perfect. Not likely to ever be perfect though.Don't let what I say scare you though. If you are looking for an application that does nearly everything you can't go wrong with Blender. Just keep in mind that some controls are switched, and the work space Y and Z axes are switched too.

How do I install Blender?

To install Blender, download the appropriate package for your platform. The Windows version comes with an optional self-extracting installer, for other operating systems you can simply unpack the compressed file to the location of your choice.

I am a user of several 3D art and modeling applications; all of which have the axes arranged with X as side to side, Y as up to down, and Z as fore to rear, Blender is the only one with the X and Y axes switched. And yes it is also the only one with the left and right mouse button functions switched. But I leave everything as is in the program because I don't want to keep having to set Blender up for my preferences every time I upgrade. I like using keyboard shortcuts, and if I set the new build to work like my other applications, I have to also reset my keyboard shortcuts. I just don't have time to do that. So I live with Blender as is, and try to keep in mind that I am working in Blender when doing so.

Provided the Blender binary is in the original extracted directory, Blender will run straight out of the box. No system libraries or system preferences are altered.

It's a free 3D graphics application and considered as one of the best free video editor for Mac. It can be used for modeling, rigging, texturing, UV unwrapping, skinning, animating, rendering, water and smoke simulations, particle and other simulations, non-linear editing, compositing, and creating interactive 3D applications, animated film, video games, or other visual effects.

Blender Foundation and the blender.org developer community are proud to present the official Blender 2.75a release. The main highlights of this release are:
Blender now supports a fully integrated Multi-View and Stereo 3D pipeline
Cycles has much awaited initial support for AMD GPUs, and a new Light Portals feature.
UI now allows font previews in the file browser.
High quality options for viewport depth of field were added
Modeling has a new Corrective Smooth modifier.
The Decimate modifier was improved significantly.
3D viewport painting now supports symmetry and the distribution of Dynamic Topology was improved
Video Sequence Editor: Placeholders can now replace missing frames of image sequences
Game Engine now allows smoother LOD transitions, and supports mist attributes animation
And: 100s of bug fixes and smaller feature improvements.Released: July 1, 2015. Released update 2.75a: July 8, 2015. Essential for GE users and for people using render passes! Full list of fixes.
