Clover General discussion

[Matgen84]

Hello

 

The commit 23688b8 introduces :

New Quirks Support:

DisableIoMapperMapping (Kernel Quirk): Added support for better VT-d/IOMMU handling.

ResizeGpuBars (UEFI Quirk): Added support for resizing GPU BARs independently of Apple's logic, improving firmware compliance.

 

That means we must have one more quirks (DisableIoMapperMapping = TRUE) in config.plist ?   ResizeGpuBars -1 is already present in config.plist ?

 

Thanks.

 

PS: Compiling latest commit, official Buildme do not erase existing  sim folder 🥲

Yes, these aren't new Quirks and have been around for a while. Until yesterday's commit, everything worked fine. Here's my config plist. 🙁

 

config.plist

Edited January 13 by MakAsrock

[Matgen84]

Hi @MakAsrock Thanks for your config.plist. Quirks parameters are some differences (true/false) because of  my old IvyBridge and my Coffee Lake-R

 

Just my opinion, I believe that DisableIoMapperMapping was introduced recently (perhaps 10 January).  Today, this quirk is not present in sample_config.plist ! 😎

 

Thank you

The new Clover is completely unsuitable for the Asus P8Z77-V Pro: i7 3770k, 16-core Corsair RAM, Gigabyte Nvidia GT640 graphics card, Asus PCE-AC68 Wi-Fi, and IIyama Prolite XB2483HSU 24-inch. I still haven't figured out why. I have almost the same RAM (Asus Z77-A) on my old computer, and Big Sur can still boot, but it's impossible to work. Currently, it uses the Open Core 1.0.4 bootloader. 
And Gigabyte Z390 Aorus Master (BIOS F11n) - i7 9700K - 16Go RAM 3000Mhz Corsair - MSI Radeon RX580 Armor - Fenvi FV-T919 - Intel 9560 ac - IIyama Prolite XB2783HSU 27" is still a pretty normal set.

VT-d has only two states: ON or OFF. What else do you want?

To make it OFF we may do:

1. Switch it off in BIOS.

2. Drop DMAR.aml table.

3. Use boot-args  "dart=0"

4. Use quirk DisableIoMapperMapping

Why anyone see any difference?

My config contains the following lines:

<key>DisableIoMapper</key>
<true/>
<key>DisableIoMapperMapping</key>
<true/>

But Clover won't boot macOS 26.2
There's a screenshot in my post above.
Until the very last commit (23688b8), everything works correctly.

Why the README.md of clover is change? In adition it's in Portuguese Brazil.

 

[MakAsrock]

My repository is fully translated into English and completely stable (commit and release d01bec6).
To protect against buggy commits, I decided to completely break away from the original source code by temporarily freezing it on the stable CloverBootloader Hackintosh and Beyond (Fork) 9c2ae43 commit.

From now on, all source code edits will be made manually as soon as the changes are confirmed to work.
Cheers! 😉

Hi @MakAsrock My old Ivybridge (OCLP, SMBIOS MacPro7,1) boot fine Sequoia using both Clover 5165 or Opencore 1.0.6. You know what: it's a miracle for this working daily machine. 😅 Of course, my Coffee Lake-R machine works fine. It's logical.

 

At the beginning, I'm talking about this new setting in config.plist:

<key>DisableIoMapperMapping</key>
<true/>

Actually, this parameter Is setting to TRUE for Ivybridge and  Coffee Lake-R. At this moment, I can't  try new commit 23688b8.

Release 5166 also loaded everything perfectly. It's just that the last four commits don't load anything with the same settings.

DisableIoMapper Mapping was added immediately after it was announced.
And anyway, it's not a case of VT-d (Virtualization Technology for Directed I/O). I disabled it in the BIOS to test.

Despite having the same quirks, OpenCore 1.0.7 works perfectly reliably. 🙄

Hi @MakAsrock Sorry for my mistakes in my previous post.

 

My old Ivybridge don't boot Sequoia using both Clover 5164 or 5166 Release. Strangely, verbose mode don't work: there is the famous Apple circle about Mac startup error message. 🥲 It's necessary to investigate why.

So what's the problem in my case? I haven't changed the config since version 5163. I just added the new keys that appeared in 5166. Moreover, everything worked in the release version 5166. 🙄

Here's an attempt to download macOS Ventura 13.7.8 (22H730):

[Max.1974]

Hello, dear friends. The new Clover updates are being made to align keys and quirks with OpenCore. I tested them and noticed that there have been major functional changes, which, in my view, make a clean installation necessary for this level of modification. The preliminary results were very satisfactory.

 

Therefore, personally, after testing the changes, I suggest a clean installation of Tahoe 26.2/3. On the other hand, my Lenovo and my Raptor Lake systems became extremely fast—I was actually surprised by the improvement.

 

From a personal standpoint, there are many improvements in the bootloader, and the credit goes to @Hnanoto Henrique’s PRs, as he dedicated many days to the project, which was ultimately approved by Slice. There is a hidden plist file in all macOS EFIs that, if deleted, may also bring improvements for those who do not wish to perform a fresh installation.

 

OpenCore was also updated, as an older version was previously being used.

 

 

Anaconda Python 3.9.6 to me is better, but Python org is fine too.

"this quirk is only needed when iGPU is enabled"

[deeveedee]

"On some systems, this quirk is only needed when iGPU is enabled."  See here.

 

I interpret this to mean that on some systems, the quirk may be needed even if iGPU is not enabled.

I know this, but my flash drive is a universal one. So I keep it enabled (it doesn't affect anything in my case. There is no integrated graphics processor physically present).

It wasn't this quirk, but rather:

<key>ResizeGpuBars</key>
<integer>-1</integer>

I changed the default value to:

<key>ResizeGpuBars</key>
<integer>0</integer>

And I was able to boot (⌘  Powered by Clover revision: 5166 (master, commit 8b0b0e44f).
I don't understand why they had to do it differently from Open Core, since they've already started syncing quirk keys.
Okay, I remembered that I once changed this key to -1 and couldn't boot either.

Perhaps you have Python is not version 3.13.7 or higher? Then there will be an error.
 

cd /Library/Frameworks/Python.framework/Versions/3.13/bin/
sudo ln -s python3.13 python
cd -

Python 3.14 is possible.
