Any click sound and red LED flashes when you turn on the main power? Not the power button but the plug to your power outlet.

Bootcamp V6.0 and above support Windows10. Mojave 10.14.6 is version 6.1.

Your question should be posted here: https://forum.lowyat.net/index.php?showtopi...861&hl=bootcamp

My MBP 2018 is now ghosting and having double images after using for a while. Restarting seems to cure it for a while.
Could it be a heat problem?

For top, case assembly. Yes. But 2015 model are long expired from official warranty. And are soon to be obsolete. We do not see any reason to go back to Apple. Do check if your unit eligible for battery recall: https://support.apple.com/15-inch-macbook-pro-battery-recall

Common issue on these model. Try to keep the Mac clean and cool.

It begins with a thin grey bar at the bottom, sometimes gets worse into the ghosting mentioned earlier.

Can cleaning the fans etc clear it? Or need more serious service?

Cleaning should be done as preventive measure. You should be watching the temperature closely. Once the LCD become defective you have to replace it.

Hi! Did anyone managed to get their 2017 model of Macbook Pro with display backlight issue (or better known as Flexgate) fixed for free in Malaysia?

I'm experiencing the flexgate issue but my model is 2017, not the 2016 that's covered, which is really annoying to see right now. Hoping to hear from anyone with an experience dealing with this!

Doubt so, unless still under AppleCare. But do try to speak to a Senior Advisor over the hotline or chat with one. Try to push them for a free or partial paid replacement. Good luck.

anyone with webcam "no video capture device were found" issue in here? Seems my webcam rosak after update to Big Sur. Tried reinstall Mac OS, tried to bootcamp to Windows, and tried other things (NVRAM clear etc.) but I couldn't bring back my webcam.

Macbook Pro 2016. Webcam was running fine on High Sierra. sad.gif

Edit: seems like a big issue and has 30 pages already https://discussions.apple.com/thread/252138459
