And again.

 

Is this possible?

Yes, with a small workaround.  Control (right) - click on the movie's thumbnail and select Edit with ➙ Quicktime Player from the contextual menu.

Neither Mac Pro 2006 through 2012 silver tower nor late 2013 dark cylinder will support a ThunderBolt display today, and there is no way to add that capability, and there never will be a way to add that capability.

To run thunderBolt displays, a Mac must have left the factory with Thunderbolt port on board -- it cannot be added later. As long as Intel controls the chips and the certification process, there will NEVER be an add-on.

Try VLC Media Player, it plays most video codecs:

If you've just copied the VIDEO_TS folder from the DVD to your Mac HD, it's not going to work. You need to rip the DVD with a ripper such as RipIT or MTR. There are several available - just search MAC DVD RIPPER with Google. Then Toast 11 should work. I use Toast 10 on my MacPro under High Sierra and it's fine.

Let it cool down.

If you have concerns, try the basics from the manual:  restart, reset, restore from backup, restore as new.

Or you can make an appointment at the genius bar.

I would uninstall Intego. It tends to interfere with the computer's operation while providing minimal to no benefit unless you work with Windows files.

Intego Uninstall

from the “recently imported” I pressed “ctrl” “x” so i cut and paste it onto the USB

That explains it, then. Copy/Cut and paste will just transfer the preview files, and they are not always the same as the full resolution original files.

Did you also delete the photos from your iPhone?

Since you already deleted the videos from Photos, you can only recover them, if Time Machine has been running, while the videos have been on your Mac. If you set up Time Machine, it makes hourly backups. Perhaps you have been lucky. Otherwise you would need to run data recovery software. But this kind of software is expensive.  Use only software with a trial version, that will show you what can be recovered, before you pay for it.

and the last file (which you can see is a video clip). When I try to open it in QuickTime though, it won't open.

What is the error message in QuickTime Player?

In QuickTime Player go to the Window menu and select "Show Movie Inspector"

The Inspector will show you the codec for the Video in the Format line.

What is the codec?

disable any 3rd party plug-ins you have installed, quit out of Safari and relaunch Safari holding down the SHIFT key.
