thanks for your time and enjoy your Mac. our doors are always open 24/7 feel free to stop by.

well make sure the slot is clean and the ram contacts as well. you can use a pencil eraser to clean the ram contacts as for the slot make sure the spring clips are locking onto the ram card properly and use a can of compressed air to make sure there isn't any dust bunnies in the corners of the slot preventing the ram from being fully seated it might be slightly cocked preventing the retainer clip from fully locking it in.

no clue as that noise is probably hardware related. loose coil or transformer somewhere maybe or maybe backlight inverter.

have you checked dell bios updates. maybe they have corrected this issue in one of them.

glad you sorted it out and happy holidays.

sorry to hear that.

If you like scripts https://github.com/corpnewt/Lilu-and-Friends compiles 44 kexts of your choosing

check your bios settings and also check your wifi switch.

maybe you have to set a timeout in the plist compare both.

i have a similar machine the 7050 SFF with skylake HD-520 it runs very well on Mojave.

hmm that is opposite to what happened on my E5420. i can boot and run fine on battery but once i connect the charger the machine goes crazy. even the backlight starts to strobe on and off rapidly.

you can try using this app. it also does usb https://www.insanelymac.com/forum/topic/335018-intel-fb-patcher-v166/

try adding PNLF clover acpi patch unless you already have a PNLF ssdt.aml file

you might have deleted your microsoft folder from your EFI volume. if you have a backup of it transfer the folder back.

maybe you need a prelinkedkernel or need to generate one for sierra?

i use layout id 27 on the optiplex 7050 with lilu and applealc. both kexts have to be current if not it wont work I use HDMI audio i have not tried any other input output ports

https://github.com/Dids/clover-builder/releases there you have latest clover option plus iso and just the clover binary without having to use the package installer

the DW1830 antenna connectors are MHF4 and if you had the intel AC-3165 it should also have the same antenna connector. you can look up the card you had previously in the machine if it was not the intel 3165 on that wiki dev site.

hit the space bar at the clover prompt. there should be an injection menu available.

what's your native screen resolution

weirdiy it shows two brcm2070A0 BT devices

sorry to see it didn't work out.... but you can try with this http://cvad-mac.narod.ru/index/bootdiskutility_exe/0-5 for windows

check to see if the BT device still shows up on your USB Bus after sleep.

then press F11 at clover boot GUI it should reboot on its own after resetting nvram

did you try replace 45C106 and 45C11E maybe also add ig-platformid 0x3E9B0000. I did not see intel injection on in config.
