10.14.5 - random crashes, maybe RAM or permissions related

[CircArK]

Hello


I run a Hackintosh with El Capitan since 2015 without a problem.
I decided to upgrade to Mojave 10.14.5, following this guide:

Z170X-UD5 TH High Sierra tips and tricks

Gigabyte Z170X-UD5 TH motherboard I decided to create a thread for Gigabyte Z170X-UD5 TH motherboard users. This motherboard comes with Thunderbolt support, which is great for building custom macOS computer. Gigabyte claims that Z170X-UD5 TH is World's First Intel® Thunderbolt™ 3 Certified...

www.tonymacx86.com



I started with a fresh install. I changed my GPU for a RX 480 (i had a GTX980 before, mainly for gaming but now not compatible anymore).

All previous El Capitan Data were wipped out and a Fusion Drive (SSD 256Go+HHD 4TB) was created

1. MB: GB Z170x - UD5 TH - FW F4
2. CPU: i6700k
3. GPU: GB RX480 Windforce 2X, connected on a 27'' AOC Q2775PQU
4. SMBIOS: iMac 16,1 (currently, suspect change is needed)

Everything went smooth and run fine. Installed 10.14.5, boot is OK, Clover (latest, 4961) works fine (USB, iMessage, Continuity, Handsoff).
Geekbench works like a charm (ST 5'500, MT 19'000) on both CPU and GPU test.




After testing, i am getting random crashes (reboot after panic) and don't know how to solve it. It comes randomly after a while (like 15 or 30 minutes) and reboot without notice.

- Sleep is desactivated in macOS
- tried with all SATA/USB/additional GPU (i keep the GTX980 to boot on Windows) unplugged, no change, still randomly crashes

Kext list:

After reboot, i just got a crash report:

Any idea how to deal with this? I searched the forum for 2 weaks now for a similar problem but without luck.
I have 2 leads:

1. I tested the memory this Memtest86 and it seams to be OK. However, with the two 8GB ram-card connected, the system crash more often (maybe related?) With just one 8GB ram slot connected, crash after 15 / 30 minutes.

2. I also noticed that wenn i copied back my backup files (documents, photos, etc.) i have some permissions problems (unable to apply new permissions to enclosed files in my User folder: it seams to work but the OS don't apply the new permissions to all files). I also get more often crashes when I play with files permissions

Any idea why it is constantly crashing?

any help is welcome
many thanks in advance

This is because you have a new username for the new macOS. You need to sudo chown -R $USER:staff files_or_dirs

 

[justinhe]

1. remove USB-SSDT_all-external_no-internal_except-HS10.aml from Clover/ACPI/patched. that SSDT is too messy for your fresh installed macOS (main cause of the crash, i think)
2. remove drivers64UEFI/apfs.efi use ApfsDriverLoader-64.efi instead (attached)
3. what ethernet card do you have? why are there 3 kexts drivers for ethernet? AtherosE2200Ethernet.kext ? IntelMausiEthernet.kext ? RealtekRTL8111.kext ?
4. config.plist is not clean, but i'll talk about that later after you tried the 3 steps

1. remove USB-SSDT_all-external_no-internal_except-HS10.aml from Clover/ACPI/patched. that SSDT is too messy for your fresh installed macOS (main cause of the crash, i think)

I got this one from here to be able to use USB2 and USB3.

Z170X-UD5 TH High Sierra tips and tricks

have followed your instruction for creating my own USB-SSDT. On mixed USB2/3 ports I disabled the USB 2 port. Now USB 3 seems to work fine if the usb device is plugged in while booting, but I observed that hot plug does not work. Does hot plug a USB3 device work on your machine? For first...

www.tonymacx86.com

which one would you recommend for my mobo?

2. remove drivers64UEFI/apfs.efi use ApfsDriverLoader-64.efi instead (attached)

I tried ApfsDriverLoader-64.efi before using apfs.efi in my actual configuration.

The problem was, that Clover was stuck with "Scan Entries ..." because he wasn't able to recognize the APFS Fusion Drive with ApfsDriverLoader-64.efi. Then, I tried with apfs.efi found in /usr/standalone/i386/ and solved this problem with this.
But ApfsDriverLoader-64.efi worked fine with just the installation on a SSD or a USB stick. It's just not working with Fusion Drive.

what ethernet card do you have? why are there 3 kexts drivers for ethernet? AtherosE2200Ethernet.kext ? IntelMausiEthernet.kext ? RealtekRTL8111.kext ?

I don't have any Ethernet card (I'm using wifi). I guess that I just have the ethernet chip/port built in my MoBo. Should i delete all of them?

4. config.plist is not clean, but i'll talk about that later after you tried the 3 steps

thank you for the feedback! I'm here to learn. Did a lot of trial/error/retry the last years while beeing registred here but almost never post. I'm curious to see your comments

 

[justinhe]

none of them, i recommend this: A Beginner's Guide to Creating a Custom USB SSDT

I don't have any Ethernet card (I'm using wifi). I guess that I just have the ethernet chip/port built in my MoBo. Should i delete all of them?

Just remove them all if you don't use ethernet on your motherboard. base on my experience RealtekRTL8111.kext could cause panic sometimes.

Logout iCloud, app store, imessage, facetime and then try this config.plist

 

[CircArK]

thank for the quick feedback, really appreciate it !

just deleted the Ethernet-Kext and tried your config.plist.

is it normal that the Serial Number is already registered by Apple?(here: https://checkcoverage.apple.com) ?
Shouldn't it not beeing registered?

 

[justinhe]

then generate another one. find one that's not registered.

 

[CircArK]

thank you justinhe

just had a Kernel Panic after rebooting with your config.plist
I just rebooted, and it seems fine (just the ventilator from the GPU who is now running at very high speed for one second during the boot phase).

I now have to test if it will crash in the next hours.

 

[justinhe]

just had a Kernel Panic after rebooting with your config.plist

New config need to initialize stuff, that's fine.

GPU who is now running at very high speed for one second during the boot phase

This is also normal on macOS 10.14.5, the new fan control policy, it was testing the PWM of the GPU fan.

 

[CircArK]

Strangely is the new config way more unstable.

now I have a crash directly when I try to login on iCloud
