kali2000 Posted February 8 Share Posted February 8 Hi my friends...!!! My laptop is a MSI with HD 4600. I have two SSD disks, one with High Sierra a other with Catalina. I boot both systems from the same EFI partition on Catalina SSD. On High Sierra all work fine, but on Catalina my HDMI don't work. I send my sendme files from the two system with HDMI connected. I can't see what is the problem. Can anyone see my files and tell me how I can fix my issue? Thanks in advance. First sed from Catalina. Send me MacBook-Pro-de-Kali-Catalina.zip Second send from High Sierra. Send me MacBook-Pro-de-Produccion-High Sierra.zip Link to comment Share on other sites More sharing options...

I would suggest you try the following: 1) switch SMBIOS to MacBookPro11,1 2) if switching SMBIOS does not fix this, add WEG boot arg agdpmod=pikera Neither option has worked. @Hervé in your guide how to patch HD 4600 posted here, in post #5, you do reference to a change in AppleGraphicsDevicePolicy kext. Is it possible that my problem lies there too? Send me MacBook-Pro-de-Kali.zip Link to comment Share on other sites More sharing options...

In fact, if you take a look at my files from High Sierra, the patch is correct and my HDMI is working. Link to comment Share on other sites More sharing options...
