Maxd13 Posted October 10, 2021 Share Posted October 10, 2021 Hello, I have been migrating from from a dell 5470 to a 7280. I have collected an EFI and adjusted to my machine with the OpenCore Configurator. I'm pretty happy with the congif, but I have 2 questions: - I'm not so sure what is the "Firmware.scap" file on the Apple/Extentions. this is file is pretty big on my EFI foler. I have read that I can delete it and it will be regenrated. Any info on that ? -I have no HDMI output... Any incorrect configuration on my EFI folder ? Thanks In advance for your help Max 211010-OC-0.7.4-7280-1.zip I had to split my EFI folder in 2 zip files. Thanks Max 211010-OC-0.7.4-7280-2.zip Link to comment Share on other sites More sharing options...

Maxd13 Posted October 10, 2021 Author Share Posted October 10, 2021 Hello Lorys, well the "file - test" work like a charm, HDMI output is back. and the full touchpad feature is a dream ! Thanks My model got touchscreen, with your EFI I lost it.. not event sure I want it since I'm not a big fan of it but I will try to compare with my previous EFI. Thanks again Max 1 Link to comment Share on other sites More sharing options...

Maxd13 Posted October 13, 2021 Author Share Posted October 13, 2021 Hello @Lorys89 I'm sorry because I'm going to ask you basic question, because I play a bit with the config.plist but I'm far from an expert.. -ioreg log: WellI didn't find out yet how to generate it..is this something that I can do with ioRegistry explorer ? if you tell me how I'm happy to do it ( see touchscreen attachement) -SSDT-DELL-LATITUDE-7280.zip: system doesn't boot if I put the file in ( see boot attachment). Normally I have a lot of SSDT files on that folder. -Education: I normally udate Kexts via the tool Hackintool, should I don't do it to avoid losing your specific config ? -Where did you put all the specific config for the model 7280, only on the file above ? Sorry for the question and thanks for your help Max Link to comment Share on other sites More sharing options...
Lorys89 Posted October 13, 2021 Share Posted October 13, 2021 @Maxd13 use my efi on the github but change the kext usb port, you have to use yours since you have an extra internal usb port which is the touchscreen. or look on hackintool that usb HS port is and correct the kext on my repo github. so I make it compatible with touchscreen models. I suppose HS08? Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted October 13, 2021 Moderators Share Posted October 13, 2021 I think Maxd13 is using USBInjectall instead of USBMap or USBPort.kext I can confirm the touchscreen model uses HS08 Try this kext USBPorts_7280.kext.zip 1 Link to comment Share on other sites More sharing options...
Administrators Hervé Posted October 13, 2021 Administrators Share Posted October 13, 2021 I'm not sure you'll get Touchscreen working in Catalina or Big Sur without some add-on software. It certainly was the case for my Skylake E7270 for which Touchscreen worked OOB up to Mojave. @Maxd13, your SysInfo screenshot seems to show you've changed your SMBIOS from MBP (which would have been correct) to that of an iMac (which would be incorrect). Is that the case? 1 Link to comment Share on other sites More sharing options...
