HT6093 How to get the OS X 10.10.1 YOSEMITE Software to understand that HW is connected/install drivers withouth the device connected?

Question

My TV was connected and working as it should earlier to day.
Then i restarted my macbook air (which has been updated to OSX yosemite 10.10.1).  When i tried to access the tv again it failed to recognise the unit. The macbook screen blinked  when the cable was unconnected and reconnected and that was it. I started going through you FAQ. 3 hours later and about 123971243*10^1233123 restarts later, I still have not been able to figure it out.
What i did find is that: I have FWversion 23,6 and Port firmware version for connection controls: 0.12.3..... and since the highly ingenious thunderbolt update needs a display unit to be connected in order to work, it led me to consider buying a windows based computer...(it would be easier to get a HDTV to work with win 3.11)... So here is the milliondollar question: HOW DO YOU REINSTALL DRIVERS FOR THE THUNDERBOLT UNIT WITHOUT REINSTALLING THE OS, and where do i find them? or how do i force Yosemite to discover Thunderbolt units without updates?
(And why is your FAQ constructed to give the impression that all you need to solve any problem is to connect you device and restart your mac?)

I'm new to MacBook Pro.
My system is Mac OS X v.10.6.8.
I used to work on my 3000 photos with GIMP on a P.C, but since I had a breakdown, I would like to carry on on my Mac as soon as possible.
Figuring out unaided a new OS after a breakdown is the best prescription for another breakdown.
Before going back to editing your photos, I suggest you need to familiarise yourself with your new OS. Get a book (eg, David Pogue's "Missing Manual…") -- now, that Lion's been out and about for some time, you can probably get the Snow Leopard (aka Mac OS X v10.6) edition at a discount. Take the time to read it and understand it, and you'll spare yourself a mountain of frustration. There are enough similarities between Mac OS X and Windows to fool you into believing almost everything works the same way, when, of course, it doesn't -- many similarities are only skin-deep.
Once you've done that, you'll be in a better position to install and use GIMP or look for alternatives.
where do I find the exact version (in french)
For French issues, you are probably better off checking the forums on MacBidouille or MacGeneration.
