Did you follow the guide by @Shaneee for your X570 setup?

Using the latest AMD Kernel Patches would be the first thing I would recommend. As the Kernel patches you are using are only configured to work with macOS Ventura or older.

Generating some custom SSDT's using your system ACPI tables and Corpnewt's SSDTTime python script would be the next. As the generic SSDT you are using isn't the best for an AMD system.

Creating a custom USB kext for your system would be the other essential task, that only you can undertake.

thank for all the tips am away from home at the moment
am new to all this
booted in mac and see the errors now look up what you said when home

Further testing I have determined that it is only Google Chrome that Freezes when I run it. Other apps seem ok so far.

I checked Kernel patches and core count and everything is in and as it should be.

Didn't touch Custom SSDT's as not sure how to do this, do you think customising SSDT's would help.

Not a massive issue as can use safari and it works.

Do you have any other recommendations or custom SSDT's?

I have reinstalled the os with the new AMD Kernel Patches.

It now seems to work great. The only problem I have now is it wont boot back in all the time. Sometimes it need a few tries.

This morning it was working well, then when I got back home from work it wont boot again.

I get that too sometimes. Doesn't matter if its a cold boot or a reboot. I've never found a solution to it but what does seem to help is having verbose boot ( -v ) enabled. Not sure why it helps though.

where is that again sorry
where would i find that again
bios
efi
argos boot

 

[Edhawk]

Config.plist, NVRAM section add it to the boot args.

 

[poppylexi87]

just a quick question


do i really need all of the commands in the string below

only put in there at first because i could not boot in before i added it

-v keepsyms=1 debug=0x100 alcid=1 unfairgva=1 npci=0x2000 agdpmod=pikera e1000=0 verbose boot ( -v )

 

[Edhawk]

First 3 x boot args are used for troubleshooting boot issues, so if you have got past the installation stage then you can remove -v keepsyms=1 debug=0x100, plus the duplicate-v at the end of the list.

The alcid=1 boot arg is wrong, it should be alcid=15 for your motherboard, assuming you are running Sequoia or earlier version of macOS. Tahoe would only require this boot arg if you have follows the guide to restore AppleHDA.kext to the OS.

Unfairgva=1 and agdpmod=pikera are both necessary for compatible AMD graphics to work.

The npci=0x2000 boot arg is used when you can’t or haven’t enabled Above 4G Decoding in your bios, your system won’t boot without one of these being enabled.

The e1000=0 boot arg is used when trying to get the Intel Ethernet port to work in macOS.

Only you can determine if you require all these boot args.

it seems to be working and stays on and no crashing either which is good
just want to say big thank for all the people helped out
i try and do the boot args on the weekend

which wifi card would you recommend for my build

 

[Edhawk]

I don’t have a recommendation.

However, I use a Fenvi FV-T919 in my Desktop Hacks.

The T919 works great with OCLP in macOS Sonoma and Sequoia. Doesn’t work yet in Tahoe, we are waiting for an update to OCLP that adds support for the old Apple Broadcom WiFi/BT cards

I don’t like Intel WiFi/BT cards, but that is just my personal preference.

If you wait a while, couple of weeks, there may be news of Apple using a MediaTek MT 7922 WiFi/BT card in their new low cost MacBook. Which would logically have support in Tahoe, but not any earlier versions of macOS.

so when apple do the next update 27 mac is it end of hackintosh
and intel support to
so we are stuck on Tahoe
I have to wait for the WIFI
thank you
