Tweak freak

What is a tweak freak?
A tweak freak is someone who modifies hardware and / or software to improve performance beyond normal and acceptable standards. Tweak freaks are obsessed with discovering the root cause of all technical problems, regardless of their relevance. However, many tweak freaks set out to use it as entertainment, as a learning experience, or to satisfy a high level of interest.
Tweak Freak is also the name of a program that was developed as an extension tool with options for controlling Mac OS X. Tweaking can cause instability in an operating system or software application and make a computer more vulnerable to malware. Likewise, excessive downloading of tweak software and patches can cause programming conflicts and system crashes. There may also be legal optimization considerations as some applications or operating system programs restrict or prohibit source code optimization.
