  • Hey there! Help pls. I use MacBook Pro…. The error ALERT.
    "The file format and extension of ‘ ‘ don’t match. The file could be corrected or unsafe. Unless you trust its source, don’t open it. Do you want to open it anyway?".
    I have installed two times the Excel application. But added to the frustration of using MS package on a MacBook.

    The Options are Yes or No. Clicking both options lead to MULTIIPLE FILES OPENING, REPEATEDLY WITH NO STOPPING. I have to force quit. No result.

    I use MACBOOK & have official Office 365 subscription.

    Clueless what to do & whom to seek help from….
    So, approaching you as favour.
