A proof of concept keylogging hack called Jellyfish has been in the news about security vulnerabilities in Windows and Linux systems, but according to ITWorld, a Mac version being worked on called MAC_JELLY. This malware takes advantage of the graphics processing environments on modern PC systems, allowing a hacker to inject code that will monitor the system by way of a unique remote access trojan (RAT). While demonstrated on Windows and Linux systems, Apple’s OpenCL environment leaves Macs vulnerable as well. Continue reading

Apple’s high-end MacBook Pro systems have two Graphics processors: an “onboard” one that uses less energy, and a “dedicated” one that is optimized for advanced graphics processing. In normal cases, your Mac will dynamically switch between them based on the demands of applications you use, but this means that any program may spur the system to keep the advanced graphics processor active, and thereby drain your battery life. 
Apple’s higher-end MacBook Pro systems come with two graphics cards: an integrated one on the CPU and the other a dedicated graphics processor. While more powerful and useful for image manipulation, design, and gaming, the dedicated GPU requires greater energy and can greatly reduce your battery life when in use.
