    Coincidentally I saw this thread about undervolting
    https://www.insanelymac.com/forum/topic/331775-guide-how-to-undervolt-your-haswell-and-above-cpu/
    It should apparently work with XPS 9560 according to author (abn6x) so I think that maybe will work with XPS 9360 to.
    I gave it a try on my XPS 9350 i76560U Intel Iris 540 (3200x1800) running 10.14.1 (had to disable SIP (0x67) in config.plist) and to my big surprise it´s WORKING.

    Skærmbillede 2018-12-04 kl. 21.58.21.png

    With these cautious settings I have increased battery life at least 10% and a slight drop in temp.
    After applying sudo ./voltageshift buildlaunchd (using my settings) it´s workin after every boot/reboot

    Only issue is that after wake from sleep it´s not working anymore and all settings return to -0

    I hope that someone here can help to solve that ?
    Maybe jkbuha ?

    This is a totally safe methode without risk of damage to hardware

    Wake from sleep issue Solved

    I changed my settings to -100 -30 -100 ran stresstest (Prime95) and it´s stable.
    (better battery life and lower temperature compared to old settings)

    But that's not what did it.
    Here´s how
    When making the sudo ./voltageshift buildlaunchd
    Use these settings -XXX -XX -XXX 0 0 0 1 (replace the X values with your settings)
    The last digit "1" will scheduled check the setting every 1 min. and amend if needed.

    This is documented elsewhere in this topic and on the forum. There are some cases where state S3 resets watchdog and some of the run-time EFI variables, hence why you see reversion on wakeup.

    The best method is to run stability tests with voltageshift and apply the optimal voltage settings to EFI. Once this is done you'll have permanent undervolting across all OSes.

    Where can I find a detailed guide for that ? I´ve been searching for that the last 2 days with no luck.

    There are quite a few detailed (albeit non-9360 specific) guides on best-practice undervolting. In general - undervolt in steps of 10mV, run prime95 && cpumark, once cpu goes belly up, increase by 5mV, reboot and finalize.

    @soto2080 can you share your clover folder and setup? I have the same model as yours and I'm unable to get Mojave to work with @the-darkvoid clover folder. Thank you.

    I can't figure out why Bluetooth isn't working on my XPS13 9360.

    I've uploaded debug zip. Any help would be appreciated!

    So, I've followed silently for some time. Have the latest bios (2.10), Latest Mojave update, in a completely fresh install. My system is quite similar to Dark-Void (only 8GB ram and FHD screen are differences). Trackpad works perfectly in Windows 10, but on Macintosh partition the I2C kext seems to be giving me problems; I can't right-click, whether by two-finger method or bottom right, preference pane seems to have no effect. Gestures don't work either. Just basic mouse movement and single-click. I've dug through the I2C troubleshooting thread, and I've concluded I don't have any GPIO pinning issues that I can tell based on IOReg and the system log of Voodoo-related entries.

    Log showed "[SSCN / FGCN] not implemented in ACPI tables", which I understood to be not a concern.

    Only VoodooI2ControllerDriver entry that stumped me was, "Warning: Error getting bus config, using defaults where necessary"

    I have nearly stock Clover installation from Dark-Void's repository. Only config.plist differences are System Serial/Board ID, choice of default booting volume, enabling the hiding of legacy windows boot entries, and adjusting the RAM entries. On the MacOS side, the only L/E kexts added are the two Brcm*, CodecCommander, and AppleHDA_ALC256, accomplished via Dark-Void's script (Sound / Bluetooth / Wireless are working properly). I am using the provided CPUFriend additions in the Clover Kexts/Other folder as I have the matching i7-8550 CPU they meant to use.

    One note: I did have a LOT of trouble getting the Gen_Debug to let me save IORegExplorer output in the /var/root/Desktop folder, no permissions to save to root-only folder, had to manually add permissions in Finder during script execution, but I finally got that accomplished, and I should have a complete debug file for any willing helpers to view.

    Have you installed BrcmFirmwareRepo.kext and BrcmPatchRAM2.kext to L/E ?
