Sorry, last post was meant for another thread, similar problem (sort of!).
Can you try one more diagnostic please. Restart the mac while also holding down the 'shift' key to boot into Safe Mode. You can release the 'shift' key when you see the grey Apple logo and the progress bar underneath it.
When the progress bar completes, log in and check System Prefs. Same problem?
1. Uninstall Avetron AVEX video app and be sure the files
are deleted from System/Library/Extensions folder.
Restart the mac and see if the problem is solved. If not then go to Step 2:
2. Remove all of the following
Xmarks for Safari
> System Preferences... > Users & Groups | Login Items.
Restart the mac and see if the problem is solved. If not then go to Step 3:
3. Uninstall CleanMyMac and
from ~/Library/Launch Agents
(you will need to make Finder active, choose 'Go' in the menubar, hold down 'option' on the keyboard then choose Library to find this folder).
Restar the mac. If the problem persists, post back.
In that list which you deleted from your earlier post is the answer to your problem. That list contains (among other things) the difference between 'Safe Mode' and your User account.
It's hard for me to suggest what else to try as I don't have access to the list. In general, though, the procedure is to remove non-Apple things systematically from these folders
1. [user/home] / Library / Launch Agents
2. [user/home] / Library/ Launch Daemons
3. System Preferences > Users & Groups | Login Items
For 3, just remove everything from the list and restart. However, for 1 & 2, don't just go deleting those files. Instead, move them out temporarily to somewhere safe, restart, then move them back in if they don't solve the problem. Also, some of those things may belong to apps that have to be uninstalled properly, so you need to consider what each belongs to and uninstall the app if necessary first.
After moving anything, you need to restart the system. All these things run on log in, so you won't see any change till you log in again.
If all of that fails, you could try deleting the entire contents of
[user/home] /Library/ Preferences /
and restarting the computer.
This will reset ALL your preferences across your entire account (every app, the Dock, Finder etc etc) back to default.

Sorry - here's the list again, slightly updated. If you can, take a look and let me know what you think before I delete all my preferences. Thanks for your time.

Now the remote is working again but the option to disable the IR receiver is still gone, so my initial problem remains. I did try deleting all my entire contents of my preferences which did not resolve the problem. It took quite awhile to get re-set up from that but I'd love to find out why the option to disable the IR receiver is still gone.
