Final Cut Pro X Trial quitting unexpectedly when previewing titles

Hi,

I have a MacBook Pro Retina 13, 2015 model, 2.7Ghz, 8GB, 128GB base model, Irish/GB keyboard layout (not sure that matters), OS X 10.10.3

This is my second, as after 21 days the first one was replaced because it was deemed to be defective. However, the new model is exhibiting the exact same issues:

1. Final Cut Pro X Trial (10.2.1) crashes regularly.

2. Mail crashes every few days.

Troubleshooting efforts with Apple Support focused on FCP X so far because it is easy to replicate. If I open FCP X, click on "T" to view the titles, and preview the "Atmosphere" title (click to select "Atmosphere title, and scan back and forward to view the title preview), the machine becomes immediately unresponsive and the application will close within 5-10 seconds.

At the instruction of Apple technical support, I carried out disk error checks, reinstalled the OS twice, once without erasing and once with erase first, opened in "safe boot mode", and created test user accounts. In safe mode FCP X quits unexpectedly as soon as I open it.

I have installed the same FCP X Trial on a Mac Mini (2012) i7, 16GB, 1TB model, and it doesn't have this problem. However, at Apple technical support's request, I downloaded a fresh image of FCP X Trial in "safe boot mode" to and again it has the exact same issue.

Right now this case has been passed to a senior analyst and I have provided logs to Apple to have engineers look at it and get back to me. I'm forwarding all my crash logs to the analyst, and hoping that they can work something out, but int he meantime, is anyone else with a MacBook Pro 13 (2015) experiencing the same thing, or able to replicate the same thing? I have been told, by Apple, that this is probably a hardware issue, but since I am now on a second brand new computer, with identical specs and experiencing the same problem, I'm assuming that it is more likely to be a software/driver related issue. That's why I'm now reaching out here, to see if others are able to replicate the same issue.

The issue with Mail crashing every few days might be unrelated, but I mention it because I have been told this isn't normal either.

Thanks,

Peter
