New to Mac. OS 10. iTunes has two libraries. This has locked the screen so that the menu bar does not display. Have down loaded iTunes and tried to delete the libraries but cannot reach them. Have also tried the Option open iTunes route. Nada.
Itunes has two libraries. This seems to interfere with the function as it will only do two things; show and empty library and another with the reduced page of the original. Both do not have the menu bar available. So I cannot manuver though any commands. Effectively it is locked. Have tried all of the usual suspects listed on the internet to including downloads. In windows I simply go to the files and delete. Tried that on the Mac but because it continues to run in background no deletions are allowed. And sometimes Finder will show iTunes files and sometimes not. Anyway to reset to default? Otherwise I would really appreciate any advice to help solve this problem. FYI i am a very very long time windows guy and very very new to Mac.
