Frustrating To No End "Right Click" HELP!

Hi, Sadly Im Stuck On A Mac, I Need Help To Change The Right Click Button From Opening A Menu To Only Looking, And I Need Middle Mouse To Do The Right Click Buttons Job, I Need Major Help…

My Laggy Computer Doesnt Let Me Develop In Piece, I Cant Look Around In The Editor, I Changed The Pan To Middle Mouse But That Only In Bp, And I Still Need To Look Around With Right Click Hold In Editor, Doesnt Work Due To Weak Computer, Help! Thanks!

Right Click For Looking/Panning

Middle Mouse For Opening Context Or Doing Right Clicks Job

Left Click, Mouse1: To Simply Stay The Same

Is This Not Possible? A Great Amount Of Struggle Just To Navigate My Editor, Making A Level Would Be Super Impossible Level Of Pain lol
