I cannot connect my macbook pro to the internet im totaly lost and need help.

You might try the following solutions (probably in this order):

Reset Safari (Click Safari at the top left, click Reset Safari, and make sure all the boxes are checked. NOTE: This will erase any autofill information you have stored as well as your browsing history.)

Check your Date & Time. (If the date and time on your system is more than a few hours off of the actual time, your wireless router may not allow the computer to authenticate to the internet. If your Date & Time is incorrect, you can fix it by going to System Preferences and clicking Date & Time.

Try reinstalling Safari. (You can download it for free from this link Since you obviously cannot do this directly from your macbook, you may need to download it onto your iMac, then move it over on a flash drive or via target mode.)

Try reinstalling the OS. (Reinstalling the entire operating system may fix the problem. You will want to back up at least your home folder(s) (user folders) before doing so. If possible, you may try an archive and install first, but this will only work if you have enough space on your hard drive to copy your user folders and then delete them. To archive and install, click options on the bottom left corner of the window before you install from the system discs.)

Wish it works ;)
