Today, an Apple rep had me test my MBP HDMI w/ a Samsung TV HDMI & that worked. My other MBPs both have Yosemite & neither work w/ my LG TV. I recently sold the 2008 MBP & before I did, I re-swapped back to the old hard drive w/ Mavericks - & it worked w/ my LG TV again! I swapped out the old 500GB hard drive for a 1 TB that I later upgraded to Yosemite & that's when the problems started. My old 2008 MBP MiniDisplay Port to HDMI worked w/ my LG TV for years. Hopefully someone will see this and have a brainwave.ĭid you try installing Mavericks on a separate partition yet? If so, did it work? If not, it may be due to a security update. However, as my partner's Air only has a thunderbolt port and no HDMI port it still doesn't work with her MAC. This is sort of fine for my MBP as I had nothing working before but it seems a bit pointless having the HDMI cable plugged in as well as I might as well just use this in the first place. It seems that there needs to be either a base signal or an earthing through the MacBook Pro's HDMI port for it to switch into an external monitor mode that will detect a thunderbolt to HDMI connection.

However, if I then unplug the HDMI cable from MBP or the amp, the thunderbolt port stops working as well and the TV displays "no signal detected". I checked that the correct hdmi port was selected on the TV for the direct connection and I could even turn off my amplifier to make sure that I was not seeing the wrong signal and it still worked as long as the hdmi-to-hdmi was still connected at both ends.

But if I then plug a normal hdmi-to-hdmi cable from my amplifier to the Mac Pro's HDMI port, suddenly the thunderbolt cable works and the Display Preferences sees the LGTV.

I have a Mac Book Pro, my partner a Mac Book Air. I am having the same problem as a lot of people with Yosemite and and connecting to a TV/external monitor via thunderbolt to HDMI but have found a sort of a solution or at least a bit more info that might lead to someone having a eureka moment.
