Can be the Logo light up?

Good grief, where do people find such silliness? No, it is not true. I don’t know the source of your quoted text, but it is 100% nonsense. Do not download anything based on such a ridiculous message.

To reinforce what stedman1 wrote, Flash Player has been discontinued by its maker, and adobe urges you to remove it from your Mac.

FAKE Flash Player downloads have been THE largest source of malware on the Mac.

'Logo lighting up' was accomplished in older models by machining out a hole in the aluminum display-cover in the shape of the white Apple logo. When the screen backlight lit up, the logo would glow.

That feature was removed, possibly because the display backlighting is done a different way (with too little light spilling out the back), or possibly for no longer being able to meet EMI-RFI shielding requirements, or possibly as a cost reduction.

Is it true?

Please share your ideas 👍🏻

This sounds like a phishing attempt to install malware/adware...

The backlit Apple logo is no more, starting about 2016 this feature has been removed.
