Chosen Solution

I’ve bought an old27” iMac Late 2009 I’m planning on swapping the HDD for a SSD. Since the iMac is open anyway. It like to swap the WiFi and Bluetooth card as well. I have bought a 653-0029 for MacBook Pro A1502 WiFi 802.11ac Bluetooth 4.0 Card BCM94360CSAX, for an iMac early 2008. Since I’m not going to upgrade that system anymore, I’d like to use this card (if possible) on my iMac late 2009. I couldn’t find a guide right away. Is there anyone who can walk me through the process? My current WiFi card is also a Broadcom. Any help is welcome.

If you are trying to upgrade your Bluetooth & WiFi to a newer standard you’ll need to invest in the rest of the parts needed for the upgrade. Review this site for their help: OSXWiFi
