Have you tried just using QuickLook instead? (locate item in Finder window, then hit the spacebar)

It took 4 trips to the local independent Mac Store repair shop to get it running, every time they fixed something, they screwed up something else.

The hard disk had gone bad, which they replaced with an incorrect replacement, then it was one software glitch after another as the tech seemed to find new & interesting ways to simply not get the job right.

I finally stood there on their sales floor and explained in a firm, but not terribly quiet voice as they were trying to sell units to other customers that I was tired of seeing them and I wanted the thing fixed properly so that I didn't have to waste time & gas to return.

I have since been rather vocal with those who I know have & use Macs regarding this experience and most likely have cost them some business.

I wish you the best of luck with your repairs.

right away after we bought this thing. It has been a nightmare. Sadly.
I am going to bring it in next week...problem is I have no other computer. Well I have one with a broken screen......

some lingering problems, just can't put my finger on them. I had one of the desk lamp versions of Mac years ago that acted wonky from time to time & eventually I simply replaced it as I probably will do with this one at first opportunity. There are lemons in every line of products.
I was lucky in that I keep my old machines (the immediate replaced machine remains in the same room with my current machine and I keep it updated as best I can and semi-ready to go) and I was able to get by with my older desk top and an iPad for a few days while they repaired this one.

Best of luck with your repairs!

Best repair software I've used. It won't fix a real hardware problem, but many problems are really with the software and can be repaired by DiskWarrior.
