1.In yahoo answers, It doesn't show hidden answers by clicking on it, If you consider yahoo popular website!
Good, now you've posted a specific complaint. Unfortunately, you haven't posted your OS version, so we still don't know what you're working with.
2.All of my video files played on this mac show a saturated white instead of a bright picture like sun for example(With quicktime or vlc)
Which color profile are you using?
Can you post a screenshot illustrating this oversaturation? If the problem doesn't appear in a screenshot, then maybe the problem is a combination of color profile and your screen brightness level. In any case, this may be a difficult problem to solve unless someone with suitable skills is actually able to physically look at your screen. Some things are intrinsically difficult without being there.
3. having a wired connection with thunderbolt to gigabit ethernet adapter significantly increases the lag(if a typical mac user here even know what ping is)
Plenty of people here know what a ping is, such as myself and dejo. Post the output from terminal, and identify exactly what you're pinging: LAN or remote, number of hops, etc.
I am sorry for all of you that find insulting the best way here, I know you really need to show off and you have nothing except some apple devices.
Sorry, but I looked at the whole thread and I don't see anyone insulting you. If you think there's an insult, feel free to report the post. Your post is the only one I see with anything faintly insulting (e.g. the insinuation in #3 above that Mac users don't know what ping is).
Here's an article you should probably read:
https://mikeash.com/getting_answers.html
It's written for people asking programming questions, but the problem-solving suggestions apply to any field.
If you're willing to be specific and concrete, then people here will probably be willing to help. If you're not specific and concrete, then no one here can possibly do anything to help, because there's no help possible when the problems are too vague.
For example reread your first post and tell me exactly how someone would be able to give you any specific solutions to anything you wrote there. It's impossible, because no specific problem was stated. If you make vague complaints and generalizations, then you should expect not to be taken seriously.
The choice of how this thread proceeds is yours.
