OLCP is mainly for real olds Macs, OLCP-MOD for Hackintoshs.

 

 

I have always used OCLP (Original) to apply post-install patches to hackintoshes.  I'm learning something new every day.  Thank you.

I've made backup of updated/ patched Ventura. 

After some work on USB (this laptop has USB2 and USB3 internel hubs) I had to work on this for Sonoma installer.

Renaming EHC1 to EH01 and addind matching amlf file, Sonoma installer starts with MacBookPro 15.1

Completly installed now, exactly sames post install patch with OLC-mod.

Like Ventura, all is working except Bluetooth, chip is identified but it needs Firmware ath3 to start, force loading hangs, i will see this problem next times.

I'm playing now with Sequoia Installer.

Edit: put it on a HDD, it works

Edit2 : Sequoia installed, Olcp-Mod need Ethernet for Metallib install. All is working like Sonoma. Next step Tahoe.

Edit3 : Changing SMBIOS to MacBookPro16,1 . Tahoe installer start, in progress

Tahoe installed on this old Acer E5-571 from 2015. But OLCP-Mod il not ready. No audio due to lack of AppleHda, and patches for wifi and Haswell GPU are not ready:

Back to the thread. The message comes from AppleAHCIPort::AbortCommands  / IOAHCISerialATAPI packed in /system/library/kernelcollections/BootKernelExtensions.kc . Yes this Acer have an ATAPI interface, sure Apple's Mackbooks haven't such a DVD device since years. 

The messages form post 1 are only informative.

Finally solved this spamming message found everywhere (dmesg, screen logs etc) They are here since Ventura 13.3 .

The best patch I've made is to put a null string instead message for the iolog call. Easy with Kernel patch, thanks to Opencore :

 

                        <dict>
                                <key>Arch</key>
                                <string>Any</string>

                                <string></string>
                                <key>Comment</key>
                                <string>Disable iolog '[AHCI][PRT][%08X] %s::%d:Port %d - called'</string>
                                <key>Count</key>
                                <integer>1</integer>
                                <key>Enabled</key>
                                <true/>

                                <key>Identifier</key>
                                <string>com.apple.driver.AppleAHCIPort</string>
                                <key>Limit</key>
                                <integer>0</integer>
                                <key>Mask</key>
                                <data></data>
                                <key>MaxKernel</key>
                                <string></string>
                                <key>MinKernel</key>
                                <string></string>
                                <key>Replace</key>
                                <data>AEFIQ0ldW1BSVF1bJTA4WF0gJXM6OiVkOlBvcnQgJWQgLSBjYQ==</data>

                                <key>Skip</key>
                                <integer>0</integer>
                        </dict>

 

Tested on Ventura 13.3+ and Sonoma. I think is ok too for Sequoia and Tahoe.

Hello, I'm encountering the same problem as you. Could you please tell me how you disabled the DVD drive in the kernel patch?

[Asural]

Is there any problem with "Remove Internal CD/DVD"?

“移除内置 CD/DVD”功能是否存在任何问题？
 

是的，BIOS 中没有禁用 DVD 的选项；唯一的解决方法是通过上面提到的内核补丁。

Sorry, I don't know about laptops.
The CD/DVD is connected to PORT0!
