Ask HN: Mac Bluetooth mouse polling rate fix?
Move your BT mouse over the window and see it do 60-70hz. Then use the trackpad and see it's 130hz.
The prevailing Internet wisdom says that this is a result of Apple's poor choice of BT hardware and to just use a USB mouse or dongle - but this is crazy.
Windows laptops do not have this problem. I have a hard time believing that my midrange Lenovo laptop has such substantially better BT hardware than a MacBook twice the price.
It's got to be software. Has anyone figured out a fix or a hack?
