Hi, Unlike macOS its quite easy to get your machine up and running with chromeOS - There is several methods and some work better than others - the easyist is by far "Cloudready" by Neverware - just head over to https://www.neverware.com/freedownload - download the installer and get rocking. Here i will try and put together a little index of machines that i personally have tested. Model Wifi Screen Touchpad USB Ext. screen Notes Dell Latitude E5410 Yes Yes Yes Yes Yes Machine runs alot better than with Windows

You could have specified that subtlety from the onset... Atheros cards are no longer officially supported in Mojave so feel free to test Atheros40 kext from other versions if you're game. You can always extract the kext with Pacifist app from past Combo Update packages available for download off Apple's web site. Failing that, opt for a better card like DW1510; AR5B93 is getting a little long in the tooth today... I took out my old little Latitude D430 out of its cupboard and replaced the DW1510 fitted into it by the AR5B93 card I have lying around. It's this exact Foxconn T77H047 card. 'booted ML and ran Ookla legacy tests. Results are as good as I expected at around 70-80Mbps: Try and adjust your local connection settings. Good luck.

Config, DSDT, and kexts are mostly wrong. Where did you obtained these files, especially the patched DSDT? You don't even have graphics acceleration.

Config.plist, ACPI and kexts folder

High Sierra does not support NVS5200M. Last known supported version is Sierra.

Broadwell is supported from Yosemite (forgot which version) up to the latest Mojave. You'll need to replace the Intel wireless card of course since it's not supported with a DW1560 or a USB device. Your system's specs: Inspiron 3558, supported devices: i3-5005U HD 5500 Synaptics touchpad ALC255 Webcam

Assuming you're using the files I linked above, you need to copy the 3 kexts in /EFI/Clover/kexts/Other/CopyToLE to /Library/Extensions Repair permissions and rebuild cache

Run this in the terminal, reboot and see if it'll sleep after reboot sudo pmset hibernatemode 0 sudo rm -f /var/vm/sleepimage sudo pmset hibernatefile /dev/null if still not sleeping either by closing the lid or by clicking sleep from the menu, then run this in the terminal and post the output log show --style syslog --start "2018-11-20" | fgrep "Wake reason"

Here replace the Config file and SSDT-I2C into /EFI/Clover/ACPI/Patched The Fn+ arrow for brightness will take a bit of programming to work, I don't know the guide to do that. Just use Karabiner-Elements app to set your Fn keys. See my E7450 or E7470 guide for more info 7280_I2C.zip

Wrong config file showing Kabylake SMBIOS and ig-platform-id, this model is Haswell. Replace Config with this https://osxlatitude.com/applications/core/interface/file/attachment.php?id=20430 Upgrade Clover loader

Replace this into /EFI/Clover. Files will work for Mojave as well. https://osxlatitude.com/applications/core/interface/file/attachment.php?id=20625
