strikas89 Posted March 22, 2016 Share Posted March 22, 2016 I just ran into the problem after updating my Hackintosh E6420 from 10.11.3 to 10.11.4. I updated by the dmg file from Apple server today. I am using Clover legacy bootloader. First, there is no audio after updated. Second, I can't boot into El Capitan without using boot parameters -v -cpus=1. If I boot without these parameters, there will be kernel panic and restart automatically. Have anyone experienced the same problem? Let's discuss.

Administrators Hervé Posted March 22, 2016 Administrators Share Posted March 22, 2016 The update reinstates the vanilla AppheHDA kext so if you were using a patched kext in /S/L/E, it got overwritten. It's a simple matter or re-applying the IDT 92HD90 patch which is readily available. For the other issue, no idea, it's kind of weird. Sounds like your bootloader config is not optimum or that you do not have correct CPU power management. Post your EFI folder and advise on add-on kexts added to /S/L/E or /L/E. I updated all my systems last night and everything went smoothly. 1 Link to comment Share on other sites More sharing options...
strikas89 Posted March 22, 2016 Author Share Posted March 22, 2016 Thanks, Herve. Can you point out the link for the IDT 92HD90 patch? I can't find that. However, there is a chance that I use the combo update from Apple so it broke up the system. Many people recommend to use only AppStore to update. Here is my EFI folder.

Administrators Hervé Posted March 22, 2016 Administrators Share Posted March 22, 2016 Download Hackintosh Vietnam Tool and install the IDT patch for the 92HD90 codec. 1 Link to comment Share on other sites More sharing options...

ecpowers Posted March 26, 2016 Share Posted March 26, 2016 Second, I can't boot into El Capitan without using boot parameters -v -cpus=1. If I boot without these parameters, there will be kernel panic and restart automatically. Have anyone experienced the same problem? Let's discuss. Same issues here, the KP shows a thing with CPU "X" Caller, We doing something wrong? (the "X" is usually no.2 4 or 5 for me.) I'm using a Dell Latitude E6420 with an Intel Core i7 2670QM, 2x4GB Ram 1600MHz, 1600x900 screen and a 256GB SSD. Once booted everything works fine. Also I seem to have USB problems when I boot directly from SSD, when I boot using the Install USB everything works as it should. Link to comment Share on other sites More sharing options...
cecco Posted March 29, 2016 Share Posted March 29, 2016 good morning to all, yesterday I made a mistake: I upgraded el capitan (bootclover) from the app store on my e6420; It appeared to restart the following error and resets itself: so I decided to reinstall el capitan again, following Jake guide (very helpful by the way) so I downloaded el capitan from the app store but the latest version, and then: the first part of the installation is spun smooth like oil, but on reboot from ssd it was presented the same mistake. Someone has already had the opportunity to confront this problem? and how it has solved? Thanks in advance. Link to comment Share on other sites More sharing options...

Administrators Hervé Posted March 29, 2016 Administrators Share Posted March 29, 2016 I guess we'll all experience this KP if installing the Thunderbolt or Recovery updates offered after updating to 10.11.4. So, avoid them. Link to comment Share on other sites More sharing options...
cecco Posted March 30, 2016 Share Posted March 30, 2016 thanks Bronxteck, with the string cpus = 1 goes; but now every time I enter this command? Link to comment Share on other sites More sharing options...
