I bought on the recommendation on a friendly tracker (thanks
ctich21 For the tip) Mobidick BCU43 on the Broadcom BCM2045 chipset:
As comrade said who advised this native chipset for Apple, here two and a half hours Yuzayu from Apple Magic Mouse - everything is smoothly, without breaks. (Ugh, ugh, ugh)
Now I realized that if you look for a BT 4.0 adapter, then you need to look for a chipset. Which Bluetooth V.4.0 chipset for Apple?
UPD .:
Google helped Broadcom BCM20702 chipset For example, in Apple Mac Pro (Late 2013), now you need to find a USB adapter on this chipset.
It seems he:
HERE ?
True, for some reason, Mac OS support is not specified in the characteristics.
And delivery will cost twice the price of the adapter, you need to look for alternatives.
UPD-2:
Judging by the information from here:
There is such an IGEAR GBU521 adapter based on the Broadcom BCM20702 chip and is nestingly supported in Mac OSX.
