iMac Pro 2nd iMac Pro Died

[andyt1979]

My second iMac Pro has just died! With exactly the same problem as my first. Has anyone else experienced the same issue?

Everything works fine and performs great for a few weeks, the first iMac Pro around 5 weeks the second 2 weeks.

One day the iMac is powered on and nothing happens, the screen is dead, no apple logo, no OS. I have tried to reset the smc, boot up in safe mode etc. But nothing.

The Mac is hooked up to 2 LG ultra fine 5k displays via thunderbolt 3, a Lacie 6big raid via Thunderbolt 3 and a belkin thunderbolt 2 express dock HD using an official apple thunderbolt 3 to 2 adaptor.

When turned on the drives hooked up cycle and make a noise but the iMac screen does nothing. The LG displays do nothing.

The same setup works fine with my 2017 15 MacBook Pro.

Does anyone have any ideas/help? Apple solution is just to provide me with a new Mac with a 3-5 week delay but never fully diagnose the problem.

Could you please stop killing iMac Pros.

If you disconnect everything?
Do you have an UPS?

I wonder if this has something to do with the "secure enclave" chip inside.

I would try this:
- Disconnect ALL external devices
- If you use a UPS, disconnect that as well.

Does this change anything?

A friend of mine has had this issue. It was an 8-core basic model purchased from Microcenter with the $1000 discount.

How about getting the powersupply, earthing of your house or office checked by a professional? Even a faulty socket can cause an issue.
You can also try getting a good wality spike-guard strip to plug in your iMac Pro.

I can see this happening once with a new product...but two times to the same guy? You're cursed!

My 10core edition has been running without any issues since late December. It is on 24/7, also using UPS. If I were you I would check the power-system, something is wrong. There is just no way you got 2 defective computers.

[doublepost=1521453953][/doublepost]Thanks for the reply. My house is less than 18 months old and the Mac/equipment is protected from surges/spikes. My MacBook Pro and displays operate fine in the same scenario. I wonder if it could be something to do with the boot system of the iMac Pro's T2 chip?

protected from surges/spikes.

You may have protected it from surges and spikes, but from high and low voltage or frequency etc issues not.
You need a good UPS to protect your investment, it is worth it, I ensure you.
It is a minimal expense when compared to your iMac Pro, anyway...

Exactly. The odds are just crazy low for something like that to happen.
