Bluetooth Yosemite JUNE 2015

How many people, like me, have lost money since the launch of Yosemite and this incredible Bluetooth bugs ? I am very dissapointed,we bought some new usb keyboards and mouses (not only one...), we use apple displays with macbooks so we use their keyboards and trackpads, we use to synchronise equipments and so and so...

RESTART THE MACHINES TO RESET THE PRAM EVERYTIME IS NORMAL FOR OUR WORK SESSIONS ?!!! >>>>>>>>> NO !!!

DID WE BOUGHT OUR MACS AND MACBOOKS ?!! >>>>>>>>> YES !!!

WHAT ARE YOU THINKING WHEN YOU LOOSE TIME AND MONEY BECAUSE OF AN EQUIPMENT THAT YOU PAID ?
