Hi, I'm planning the last upgrade on my aging iMac. I discovered, this iMac using seperate bluetooth (usb) and wifi module (minipcie), but the newer 2012 and 2013 series using combined m2 (ngff) module. I'm plannig the following "upgrade" - buy this http://www.osxwifi.com/apple-broadc...-bluetooth-4-0-with-adapter-for-pc-hackintosh - remove minipci-e wifi and usb bluetooth from my iMac Mid 2011 27" - try to reroute bluetooth antenna cable close to minipcie slot - bring usb d+/d- from original bluetooth cable to the adapter, if the minipcie slot on the imac's logic board omits usb signaling. - install minipci-e to ngff converter and the broadcom bcm94360cd to the slot and connect four antennas - install the original minipci-e wifi module to with the pci-e adapter to my hackintosh on my workplace Anyone has done this before? Anyone know the length of the cable or the position of the original bluetooth antenna on the iMac Mid 2011 27"?
