Since I recently upgraded my iPhone, I wanted to try the Continuity features that the Apple ecosystem has to offer. However, since I have a mid 2010 iMac, Handoff is not supported. I've been looking for unofficial resources, and have reached no conclusions.
Has anyone achieved this, or know how to? Thanks a lot!
P.S: Here are some articles I've found, just in case they can be useful for you:

Yes–but you'll need a hardware upgrade and some third party software.
Continuity relies on two pieces: Bluetooth and Wi-Fi. These need to be "correct" to work.
Check your iMac to see what Wi-Fi chip you have. To do this, open up System Profiler and look under Wi-Fi. If you have an Atheros chip like this teardown by iFixit shows, you'll need to replace it with a Broadcom BCM94360CD chip. If, however, you have a Broadcom Wi-Fi chip, you can choose to either replace it with the same board, or you can simply install a Bluetooth 4.0 dongle. If you do decide to use a dongle, note a few things:
Once you've done that, use the Continuity Activation Tool to activate Continuity with your upgraded Mac: just run the app! Note, as always with third party hardware that works on a low level, you should use this with some caution. Make sure you have a backup (just for good caution), and nothing is 100% guaranteed. With that said, it's a very reputable tool, so I wouldn't be too afraid.
