Serious problems with Mac Pro amplified by upgrade to Catalina.

Grant Bennet-Alder,

This is the only Kernel Panic Report I found inside the folder you referenced. It is the only file with an extension .panic. There are other files but none ending in .panic. I have added text from one of the reports in the folder.

Grant Bennet-Alder,

I did run Diagnostics and it didn't find any problems. Immediately after I ran Diagnostics and re-started my Mac Pro and it crashed a short while after. Diagnostics is obviously an unreliable tool or at least one we can't completely trust.

One thing I noticed is that my Mac Pro is crashing and re-starting on its own when left unattended. I initially thought it had something to do with the Screen Saver or the Energy Saver function so I changed the Screen Saver 'Start after' function to 'Never' and 'Turn display off after' function to 'Never'. I DID NOT change the 'Put hard disks to sleep when possible' function and left it checked (I believe this was the factory's default setting). The two changes in settings didn't seem to have any effect on the re-starting problem because immediately after I made the changes and left the computer unattended it crashed and re-started again.

I noticed a panic report was produced after the re-start. It does have a bunch of characters in the beginning just like all the others but I noticed a few more legible characters at the end that I will try to post here. In case you are able to read it I would appreciate your feedback if anything makes sense to you.

Thank you again for your help.

2. OWC Mercury Elite 12 TB software-based RAID drive (Mode 0)
3. OWC Mercury Elite 12 TB hardware-based RAID drive (Mode 0)

New Software I have installed as a consequence of the upgrade to Mac OS Catalina:

2. EndNote X9 Research and Bibliography software
3. Roxio Toast 18 Titanium Media Suite and DVD/Blu-Ray burner app

6. Adobe's Creative Suite 2019 apps (Photoshop, InDesign, Illustrator, Lightroom, etc...)

I hope this helps and thank you again for your help.

Just one important piece of information I wish to add:

I also own a MacBook Pro 17" (2010), a MacBook Pro 13" (Early 2015) and a Mac Mini (Late 2012) with an Apple 27" monitor. They are running the following operating systems:

1. MacBook Pro 17" (2010) - Mac OS 10.13.6 High Sierra
2. MacBook 13" (Early 2015) - Mac OS 10.15.1 Catalina
3. Mac Mini (late 2012) - Mac OS 10.15.1 Catalina.

All three computers above behave flawlessly and never freeze or crash. I run the same software on all of them. The problems are restricted to the Mac Pro.

Thank you.

Grant Bennet-Alder,

Thank you for your help and reply.

I tried to post the report you requested but it wouldn't work using the additional text window below. I added the text and then pressed the button add text but, in addition to being extremely slow, it wouldn't do anything. I will try to add the text to a separate reply post.

Please let me know if I have done it right.

Thank you, again.

Grant Bennet-Alder,

I can't do it. The additional text box doesn't work. It nearly freezes and becomes very slow in responding. After I add the text and press the button 'Add Text' nothing happens.

I also tried to add the text as a reply but received a message stating I had exceeded the 5,000 word limit.

Important note: I was only able to add text to the reply box using Firefox. Safari wouldn't even allow me to do it.

Thank you again for your help.

Grant Bennet-Alder,

I figured it out. The 'additional text' button you recommended opens a window that only allows 100,000 characters to be added.

I copied and pasted the Kernel Panic Report to BBBedit to check the character count and it shows the report has 2,873,232 characters (nearly 3 million characters).

This is the reason the 'add additional text' isn't working.

Grant Bennet-Alder,

Thank you again for your help and for reviewing the information I posted.

Please help me understand this process. How and why did my computer produce this junk that appeared on the Kernel Panic report? What is wrong with my computer that is causing it to behave this way? All my other Macs don't have this problem so it is clear the problem is the Mac Pro. Is there anything I can do to solve this problem? My computer froze today more than 10 times and it is still early morning for me. I can't use it to do anything and it has become virtually useless.

What should I do?

Thank you in avance.

Guy Jenkins,

I get far more than the 4+ freezes per day you reported and I also experience the same automatic reboots. I noticed the reboots tend to happen more frequently when the computer goes into screen saving mode but don't know if the two issues are related. This has been happening since I purchased the Mac Pro and the issue is unique to this computer - I have several other Macs and not a single one displays any of these problems.

Grant Bennet-Alder and Guy Jenkins,

I checked my Mac Pro and my Boot Firmware version is the same as Guy's - 133.0.0.0.0. I am also running the very latest release of Mac OS Catalina which is 10.15.1.
