Operating Systems OS X (Apple) 12-Core MacPro (2013) kernel_task over 1200% Post 303034568 by Neo on Monday 29th of April 2019 10:52:23 PM

Yesterday I visited the Apple Care center after seeing Avengers End Game to pick up my Mac Pro (Late 2013) - 2.7 GHz Twelve-Core, MacPro6,1 (A1481). Apple changed the logic board under warranty and told me all was "normal" again.

While I was there, I asked to see the defective logic board. Apple mentioned that the board was sent to the factory when they requested a new one, so they did not have it at Apple Care.

I also asked if the good folks at Apple Care could tell me exactly what chip or part of the logic board had failed. They replied that their diagnostic test equipment only indicated "pass" or "fail" on the logic board and did not designate or indicate which parts of the board had failed. I asked them if they had any idea why the logic board failed. They replied that many Apple logic boards fail and they don't know the exact reason. For me this is the second logic board to fail in the same month, one on this Mac Pro and one on a MacBook Air. Seems like Apple has a lot of logic board failures, at least from my experience.

My recommendation is that all owners of Macs extend their Apple Care warranty as long as they possibility can since Apple seems to have a fairly high rate of logic board failures and the cost of Apple Care extended warranty is much less than the cost of replacing a logic board.

Now back on my desk, my Mac Pro seems to be running normally again. I just installed the latest version as of today, Mojave Beta 10.14.5 and all is well and she is humming along normally.

Overall, I am very happy with the support I received from Apple Care in Thailand. It's impressive that Apple can provide such great service on the oppositve side of the world, The technicians and all staff were highly professional and enjoyable to work with. They resolved the flawed logic board problem with MacPro quickly and under warranty, so there was no cost or charges to me, only smiles and questions like "how much did you pay for that", since I assume they do not see a lot of 12-core Mac Pros in that particular location where most customers are their to get their iPhones repaired, especially the iPhones which have been underwater!

Apple has a great warranty program globally. I highly recommend all Apple Mac users keep their extended warranty programs up-to-date, especially in light of the apparent frequency of logic board failures.

It's good to have this great 12-Core Mac Pro with 64GB of memory up and running normally again.

Thank you Apple!

NAME
SubmitDiagInfo -- sends diagnostic information to Apple SYNOPSIS
SubmitDiagInfo DESCRIPTION
SubmitDiagInfo is a system process which runs periodically. If the user has opted-in for automatic reporting of diagnostic and usage infor- mation, then SubmitDiagInfo collects and sends to Apple any recent diagnostic information which has not yet been sent to Apple. SubmitDiagInfo also cleans up any diagnostic and usage information which was created more than one month ago and is no longer needed. Sending diagnostic and usage reports to Apple helps us improve the quality and performance of our products and services. It helps Apple identify common usage trends and issues that enable us to allocate our resources efficiently, and it helps us provide better support services to you and other customers. All of the diagnostic and usage information is collected anonymously from your computer in a way that does not personally identify you. Reports may include the following information: - Details about application or system crashes, freezes, or kernel panics. - Information about events on your computer (e.g. whether a certain function, such as waking your computer was successful or not). - Usage information (e.g. data about how Apple and third party software, hardware and services are being used). Automatic reporting of diagnostic information is off by default and no information is sent to Apple unless a user has opted-in to automatic collection of diagnostic information. A user is offered the opportunity to opt-in for automatic collection of additional diagnostic and usage information after the user has manually sent a crash, hang or panic report to Apple. Users may at any time opt in or out of automatic reporting in the Security & Privacy pane of the System Preferences application under the "Privacy" tab. All diagnostic and usage information which is eligible for automatic reporting is visible in the Console application under the "DIAGNOSTIC AND USAGE INFORMATION" heading in the application's sidebar. (The information appears here even if a user has not yet opted-in for automatic reporting.) For security purposes, some system diagnostic information will only be visible to admin users and will only be submitted when an admin user is logged in. Users who need technical support should use http://www.apple.com/support or other authorized support channels. Developers who are ADC mem- bers should submit bug reports using http://bugreporter.apple.com in order to allow for two way communication between Apple and the bug reporter. SEE ALSO
