@laobamac_yyds Well done!  You might be the only one who can fix BluetoolFixup.kext so that it doesn't break incremental OTA updates.  Thank you for all you're doing.

 

I'm afraid this can't be repaired, haha.BlueToolFixup modified the bluetoothd file, which will definitely destroy the integrity of the system.

Thanks @laobamac_yyds

Yes. WEG 1.7.1d5 is working fine. There are no errors during recovery or system startup. We'll see what happens during the update.

Well,that's good.

But had better use 1.7.1d6,there were some reports said that d5 maybe cause kp on some platforms during OTA.

Hey guys,

 

Is there a trick to getting RC installed (I've got the same issue installing betas before, so I don't think it's the actual update that's faulty)? I got the incremental update, all good, rebooted, had to switch OC from "EFI" to MacOS Installer, it does something, then reboot, then it switches to boot into the system, but MacOS Installer option is still there, and if I do choose to boot back into the system, no update has been applied. So looks like it's not applying the update. And if I chose MacOS Installer again (already did 3 times so far), it does the same thing. Loads something, probably ok, but then reboots, and the update is not applied.

 

I should probably mention I'm using the AppleBCMWLANCompanion kext, not sure if that makes a difference or not. I'll probably remove it anyway, since I'm getting incredibly slow speeds (couple hundred KB/s downloaded). I can get better speeds with my Android phone connected via data cable, and USB Tethering enabled.

Anyway, I'm just curious if you guys encountered the same issue or if you have any ideas what's causing this.

 

Also, is there a fix on the boot drive selector in OC boot screen? I don't think you're supposed to manually move it to the MacOS installer.

I had this problem on an older machine. After updating, it reverted back to the MacOS Installer. If I chose to boot normally, it wouldn't update anything. I couldn't fix the problem myself at the time. I was using OC version 1.0.4, two years ago. I solved the problem by using Clover to install, but I had to keep an eye on the screen to make sure I chose the boot option and successfully install.

The previous relevant explanation is as follows. If you don't know what this WEG is, you can take a look first.

Well, nearly 20 graphics cards have been tested, and 4 of them have the problem of restarting after the second stage of OTA. The troubleshooting found that they seem to have mistakenly did not overwrite the connector data.

I changed to a simpler and faster method to judge whether the file exists directly through VFS, which can achieve faster startup speed and stability.

 

Tested graphics card:RX460，RX570，RX590，RX5600XT，RX5600OEM，RX6600，RX6900XT（All are official versions or XFX, ROG）

 

Please use 1.7.1d7, this is the final version! I won't modify it again until I encounter a new problem. At the same time, I have open sourced it and submitted it to PR. Welcome to check it out.

Hey @laobamac_yyds

Is there a difference between installing the AppleHDA with MyKextInstaller and applying root patches for it with OCLP-Mod? I'm guessing the answer is yes, but I'm trying to understand whether there's a benefit from using one over the other.

 

Also, I'm gonna try the WEG kext above on my RX580 and let you know if any issues.

Hello! They have no difference in installing AppleHDA patches, with identical steps, files, and KDK. You can choose to use what you like.

 

Additionally, if possible, please try to see if 1.7.1d7 fully supports normal systems, recovery modes, and OTA. If there are any issues, please let me know. Thank you!

Alright... :) I've tried MyKextInstaller for AppleHDA and...didn't make any difference... I've watched the video you've posted, it's super useful, but unfortunately it didn't do anything for my system. Applying root patches with OCLP-MOD however, worked fine. That's why I was curious if there's a difference between these two methods.

 

Also, yes, I got the WEG 1.7.1d7 and....it doesn't work. But I'm pretty sure I would get the same thing with the official version, as well. Right now it's booting to a "no signal" screen.

 

It might be worth mentioning that I'm using the MacPro7,1 SMBIOS. Usually, with this SMBIOS, you wouldn't need WEG. I was using it only to silence those purple lines that appear (as a test, I've learned) right before Desktop.

 

So, for my specific case, I don't necessarily need WEG at all. But using it seems to cause issues.

 

Also, another news, and I'm not sure what exactly made it work... Without AppleBCMWLANCompanion kext (removed the firmware as well), and with WEG enabled, boot selector behaved perfectly, selecting MacOS installer. Also finished the installation successfully and would have probably booted perfectly fine back to Desktop if it weren't for the "boot to no signal screen" issue I've mentioned before. :)

 

So...that's kind of where I am with testing this.

 

Booting to Recovery with WEG has the same issue (boot to "no signal" screen)

Well, since the original version also has the same issue, there won't be any difference in 1.7.1d7.

 

Because I only fixed the issue of getting stuck in KextLog when booting macOS Tahoe recovery mode and updating the system, and did not modify any other patches.

 

I will continue to wait for the test results from others. However, thank you for your reply!

As far as I know, this is an issue of using this card (RX570 and similar might have the same issue) with MacPro7,1 SMBIOS. I've used to use iMac19,1 before, and with that one I would need WEG to boot. Otherwise I would get a boot to black screen. With MacPro7,1 I don't, but also seems like it's creative issues if I do use WEG...

 

Anyway, keep up the good work. :)

The RX580 relies on the WhatEverGreen.kext which will cause a hang up during the installation, whereas a 7,1 SmBIOS does not.

Without this kext in place, you will see purple lines on screen for a few seconds but they will disappear after a while and will not pose any problems during or after.

 

As I said I rely on this method for a successful Tahoe Update or Clean Installation each time and it works.

I don't know if I can use @laobamac_yyds revised WEG.kext on my iMac 20,20 install USB to see if I can do a straight installation without resorting to the fore mentioned method with the 7,1 method but about to test it and see. 

I tested the same graphics cards (RX580, 570), and they all worked well with 1.7.1d7 + iMac20,2, just like Sequoia did perfectly before.:thumbsup_anim:

Hiya my friend, I don't know if I understand your query but for me to successfully clean Tahoe installs or updates, I have to use a USB installer built for a Mac 7,1 Pro SmBIOS (Mac Model) machine,

For an Update, after the download, I reboot with the 7,1 Pro USB and boot off it and choose the installer volume at the Boot Menu.

 

Let the installation go all the way through choosing to boot off the USB after each stage until I reach the setup screen.

At that stage I don't let it go any further, I remove the USB and replace it with my usual chosen Mac Model USB for a iMac 20,20 SmBIOS and reboot.

 

On reboot the machine will go right back to the Welcome Screen and continue with the setup with your chosen Mac Model oppose to the 7,1 Pro.

That is of course if a 7,1 if your SmBIOS is not your choice. This same procedure works for clean installation as well because the RX580 will not initially work with the RX580 Card.

 

The RX580 relies on the WhatEverGreen.kext which will cause a hang up during the installation, whereas a 7,1 SmBIOS does not.

Without this kext in place, you will see purple lines on screen for a few seconds but they will disappear after a while and will not pose any problems during or after.

Cheers.

 

I've managed to install it, after removing AppleBCMWLANCompanion kext and adding WEG (the one from above, just for testing).

 

The installation went perfectly fine (not sure if it was because of removing AppleBCMWLANCompanion or adding WEG, but I'm leaning towards the first one-will actually test that theory really soon). The problem is booting afterwards, which, as you said, if you're using a MacPro7,1 SMBIOS and WEG, it won't work. It does work without it though.

 

So let me try to upgrade again, on another partition, and see if everything ok. Will let you know. :)

 

yeah, looks like laobamac's WEG works in the context of iMacs. For MacPros, we've got the same issue. Which seems to be intended, since that was not the point of the fixes being applied to it.

 

So, for you, if you're on iMac SMBIOS, this last version of laobamac's WEG might be the winner. :)

@arsradu, just try to use boot flag agdpmod=pikera and you will not face any black screen with Whatevergreen enabled. I am also with SMBIOS MacPro7,1 and I am fine with and without Whatevergreen enabled.

@laobamac_yyds, I suppose you can add the Radeon VII to graphic cards to success with 1.7.1d7. Just tried to boot a Tahoe USB installer with 1.7.1d7 and it worked flawless up to the GUI. More feedback from my side at the beginning of next week after the OTA update to macOS Tahoe 26.1 release.  

 

Like always many thanks for all the great stuff you are doing 💯💫

Great!

I will wait for the good news of your successful OTA! hahaha

 

1.7.1d6 is already part of my EFI-Folder distribution for X299:

 

Please no further updates, otherwise I will run out of version numbers for my EFI... 😅

Will test to confirm. :) I usually didn't need this boot arg before. Enabling WEG was enough. But it's true that I was also using an iMac SMBIOS. With MacPro SMBIOS, I don't need WEG, and if I do enable it, I'm getting the issue above. Will try first the update, since that was the main issue here. And also the boot with WEG and agdpmod=pikera. Will see how it goes. Thanks for the advice! :)

I am using boot flag agdpmod=pikera since SMBIOS iMacPro1,1 and now also with MacPro7,1.. 😉
