“It’s actually bad luck to say MacBook inside an office. You have to call it ‘The Scottish Laptop’” is a jocular saying that has been printed on many images. William Shakespeare’s play Macbeth (1606) has this famous theatre curse, and actors avoid saying the name.

Wikipedia: MacBook 
The MacBook is a brand of Mac notebook computers designed and marketed by Apple Inc. that use Apple’s macOS operating system since 2006. It replaced the PowerBook and iBook brands during the Mac transition to Intel processors, announced in 2005.
   
Wikipedia: Macbeth
Macbeth (/məkˈbɛθ/, full title The Tragedie of Macbeth) is a tragedy by William Shakespeare. It is thought to have been first performed in 1606.
(...)
While many today would say that any misfortune surrounding a production is mere coincidence, actors and others in the theatre industry often consider it bad luck to mention Macbeth by name while inside a theatre, and sometimes refer to it indirectly, for example as “The Scottish Play”, or “MacBee”, or when referring to the characters and not the play, “Mr. and Mrs. M”, or “The Scottish King”.

On my first ever visit to my employer’s HQ yesterday, I accidentally breached engineering etiquette when I mentioned my computer. Apparently it’s bad luck to say “MacBook” in an office; you have to call it “The Scottish laptop”.
