I even factory restarted my MCP, and still have the issue, can somebody actually help... Please look at the other discussion, for a better understanding, do i have a missing file or anything? I took it to apple store, ran every test and it said I everything, and they didn't know why...

remind me what is "MCP" ...(?)

To trouble shoot further you can:

—Test issue in another user (or guest user) account Set up users, guests, and groups on Mac - Apple Support

This will tell you if it a universal issue or isolated to your user/admin account. 

—SafeBoot How to use safe mode on your Mac - Apple Support will sort many anomalies

Takes a bit longer to get to the login screen, does a quick disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, font cache, etc.

Login and test. Reboot as normal and test. Caches get rebuilt automatically.

no insight or resolve—

run the user Diagnostic...not as definitive as Apple's own AST2 (Apple Service Toolkit) back bench diagnostic, but may kick out an error code.
