iMac keeps crashing - Crash report says "Full Panic"

[smael123]

After purchasing a new iMac it keeps crashing repeatedly when using Photoshop.
I have been many rounds with both Apple and Adobe support (Norway). Both have admin my iMac

Apple

• checked settings adobe software + iMac
• delivered crash reports
• delivered to support -> 5 days stress test = Approved

Conclusion: Software related issue

Adobe

• Installed support´s version of CC
• Checked settings in software

Myself

• Rolled back versions
• Wiped machine twice (type hard reset with HDD formatting)
• Only non-native software: Adobe

Reaching out here for help. I see many struggle with software itself, but my machine goes black and must reboot. Very anoying when working as a designer/developer. It´s like a Carpenter´s hammer gets tossed to the moon, and need to drive to the store and buy a new one. Like 15-20 times a day, EVERY DAY!

Last attempt based on another thread in this forum: I turned the GPU off in Photoshop settings (some issue that it was related to unsupported graphics card) = no fix in my case

[c.pfaffenbichler]

Photoshop cannot crash the OS so the issue could be a hardware, driver, … 

Does turning off »Use Graphics Processor« in the Performance Preferences (Photoshop > Preferences > Performance > Graphic Processor Settings) and restarting Photoshop have any bearing on the issue? 

[smael123]

Thanks for the reply. 
My iMac doesn't crash at all if I don't use Photoshop, so it is a little hard to believe it's not related. 

Turning off the graphic processor had no effect at all I'm afraid.

If a Bridge collapses it has to be the fault of the car currently crossing it? 

Modern OS’ cannot be crashed by an application – with Mac that was the big thing when Mac OS X was introduced all that time ago. 

That Photoshop is the only application you use that reveals another compenent’s issue does not make the issue Photoshop’s even if it may look like that … 

Unfortunately the problem could be a RAM-component, a low-level driver, …
