    • By using the normal way via Appstore, just click "updates" and download 10.12.6.

      Btw, after messing around with Niresh installer ( thanks a LOT for his effort ) i desided to try other ways ( out of respect for Niresh and his his awesome job helping us out i wont tell the name of the other installer ) i used a well known installer to install Sierra, and it worked well, and this time with the correct settings for the screen right out of the box, no more laggy desktop and 3mb display.

      And just now i tried to install High Sierra on my laptop, with the sudo/terminal way, and it was an instant success, just like installing it on my desktop.    The High Sierra MacPwn wouldnt work on my laptop.
    • how you updated niresh sierra??
    • you want to update the applications from app store? if yes, its safely. if you want to upgrade from yosemite to sierra, I dont think is possible.
    • Updating Sierra to 10.12.6 ( from 10.12.5 ) solved the problem for me, and probably will for you as well.
    • Thanx for your reply demy076. My problem solved itself by updating from 10.12.5 to 10.12.6. After installing 10.12.6 and restarting my screen was perfect.

      I still dont know why my screen was ok in  Yosemite Zone but not in Sierra Zone though.

Moutain Lion !!

After a mandatory update from 10.8.4 to 10.8.5

~Not all Broadcom devices where not supported in this new update.

For device 8449 that is 0x2101

that was not working anymore after the update to 10.8.5

--------------------------------------------------------------------------------------

Open up your "SystemInformation" goto "USB" and find your BluetoothDevice.

Get the "ProductID" in this case its 0x2101 convert this Hex number to DEC and you will get 8449.

In case of broadcom look for it inside the IOBluetootfam.kext

The name or ID that is in the info.plist that is closest to your own ID " in SystemInformation 8449"
