老本子加个蓝牙 4 的适配器，能支持 handoff 和 airdrop 功能么？

老本子10 mid mbp，配置升级了，跑起来还不错
加个蓝牙适配器，usb那种的，可以支持osx的性功能么？
比如handoff
ifixit上看了下，可以自己手工换网卡蓝牙模块
但是貌似件要求比较特殊，不太好买

只能更换内置的，usb 的不行

@steveshi 做了点功课，还真有！MacRumors出品的Continuity Activation Tool 2.0，支持将部分“老旧”mac开启handoff功能，包括使用USB bluetooth dongles（还学了词dongle, 加密狗、U盾，哈哈）。原始链接在这里在这里，各位看官请移步：

dongle就是USB装置的意思
U盘，SD卡读卡器，3G的USB上网卡，等等之类的都算是dongle

上面说最好是用 BCM20702 芯片的

Bluetooth 4.0 USB dongles

A few important notes about using CAT with USB Bluetooth 4.0 dongles:

Bluetooth 4.0 dongles based on the Cambridge Silicon Radio CSR8510 A10 chip (e.g. Inatek Nano) are not compatible with CAT.
The recommendation is to look for dongles based on the Broadcom BCM20702 chip, which are similar to the ones used by Apple in their Continuity compatible Macs. A few examples: Asus BT400, IOGEAR GBU521, GMYLE, and many others. Compatibility with CSR dongles is not guaranteed.
Instant Hotspot currently doesn't work reliably when using a dongle. This is a known issue, no workarounds have been identified yet.
Atheros Wi-Fi AirPort cards will prevent Continuity from working even when adding a Bluetooth 4.0 dongle. The System Diagnostic feature of CAT tells which Wi-Fi brand is active. There are no workarounds and no patch is expected to change this, an AirPort card upgrade is required.

@jjit 嗯，看了下，不过这个工具需要一些系统权限，会降低整个系统的安全性。看来最好的办法还是升级机器，真郁闷
