‘Continuity Activation Tool’ now supports Bluetooth 4.0 Dongles, lets you use Handoff on older Macs

Continuity is a really useful feature that Apple added in OS X Yosemite and iOS 8. It lets users seamlessly switch between their Macs and iOS devices, continuing where they left off. The feature was however not compatible with older Macs, even some that had Bluetooth 4.0.

Continuity Activation Tool, released a month back, added Continuity support to older Macs with Bluetooth 4.0, and the tool in its most recent update adds support for Bluetooth 4.0 USB dongles. Which means that even if your Mac doesn’t have Bluetooth 4.0, you can buy a Bluetooth 4.0 dongle, and use Continuity features.

Here’s a chart made by the developers of the tool detailing Continuity support on various Macs:


Here are more details on the Bluetooth 4.0 Dongle support:

  • 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 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.

To download and install Continuity Activation Tool, visit this link. Note that installing the tool modifies low level system files, so exercise caution when using it to avoid any problems. The tool also disables driver verification, making your system less secure.
