No need to re-install macOS at all. If version A02 is not available then go for A03 indeed (i.e. the oldest version available off Dell's web site) before re-upgrading to A12.

Revert to BIOS A02 to begin with, then to BIOS A12.

All my laptops run in BIOS legacy mode, I do not use UEFI, even on my E6220/E6230 or E6440. I don't use iMessage (which indeed needs clover to work) but FaceTime and other apps work perfectly.

You can always disable CoreStorage and revert to traditional disk mode. But I don't think it'll make any difference... More likely to be PWR related patches required in your DSDT.

A very large and regularly-updated set of Apple Macs ACPI/IOReg dumps is available at Applelife.ru here.

Following up on the Yosemite/El Capitan/Recovery/Sierra logos, I made up new High Sierra logos/icons for the Chameleon/Enoch bootloader so that High Sierra partitions can too enjoy their own icons. Fits nicely along all the other icons. Attached .png files are to be placed in the /Extra/Themes/Default folder. HighSierra_themes_logos.zip HighSierra_themes_logos_2.zip

Moving post to its own thread.

Quick note to confirm that Enoch r2885 boots High Sierra without as much as a cough. http://www.insanelymac.com/forum/topic/231075-chameleon-24svn-official-pkg-installer/page-211?do=findComment&comment=2447091

Please! https://osxlatitude.com/index.php?/topic/8696-is-my-wireless-card-compatible-with-os-x/

You could try CodecCommander kext or EAPDFix kext. NB: no double or multiple posting for the same matter please.

Correct. https://www.intel.com/content/www/us/en/support/graphics-drivers/000005556.html

Did you disable hibernation? You can check status with Terminal command pmset -g. Also check your EnergySaver PrefPane and disable any option that may wake the computer from time to time. Also make sure that BIOS parameters such as Wake on LAN are disabled. Difficult to say anything about your wireless until you specifiy the model of the card you use. No reason why you would not be able to regenerate a CPU PM SSDT but you can re-use the table you used in El Capitan. There's no need to regenerate a new table each time.

As stated in post #1, it's the IO address of the audio device. You'll find it in the DSDT or in IOReg via any explorer tool such as IOJones, IORegistryExplorer, ioreg command line (e.g.: ioreg | grep HDEF) or similar. * DSDT example: Device (HDEF) { Name (_ADR, 0x001B0000) // _ADR: Address [...] }`* IORegistryExplorer example: * command line example: E6230:~ admin$ ioreg | grep HDEF | | +-o HDEF@1B In the above examples, HDEF audio device is found at address 0x001B0000. In the Info.plist file, this will be reflected as follows: [...] <key>HDEFAddress</key><array> <string>1B</string> [...] If the device were at address 0x001F0003, the entry in Info.plist would be: [...] <key>HDEFAddress</key> <array> <string>1F,3</string> [...] Basically, it's written as a single byte (without heading zeroes) or a pair of comma separated bytes (without heading zeroes) if lower byte is not null (0x0000).

'says it all in the D630 thread: For models with Penryn CPUs only - - - - - - Please note that: Sierra requires a Penryn CPU with SSE4 instructions set [...]. Merom CPUs [...] do not have such instructions set and do not allow Sierra installation. - - - - - - As such, as long as your laptops have the required CPUs, you can proceed exactly the same way as for Yosemite and/or El Capitan, adjsting the SMBIOS if necessary.

No, it's more a matter of having the correct/supported Bluetooth module in place. https://support.apple.com/en-us/HT203106

Moving to the non-E forum section... You don't need an earlier OS X version to begin with, no. I invite you to consult the other 6430u topics found in this section where you'll find indication of the highest BIOS version to use (I think it's A06). Use the forum Search facility on "6430u".

Why don't you download Sierra installation app off AppStore and proceed with a full vanilla installation rather than keep trying with a distro? You can easily create a fresh USB installer and practice vanilla installation on a separate partition.

Yup, see previous answers.

When you plug HDMI in, do you then manually select HDMI audio at all? Isn't it visible in the audio PrefPane? The HDMI display has audio capabilities, right?

DW380 ids are listed in my E6230 guide... It's a simple matter of creating a new model entry in the kext's Info.plist file by copying/pasting an existing entry and adjusting the device ids to the DW380's (in decimal). But don't expect all macOS Bluetooth functionalities to work or work well. If you want full AirDrop and full BT functionalities, opt for an Apple BCM94360CD with adapter board. That'll work 100% OOB. Re: HDMI audio, erm, you do have audio with patched AppleHDA, right? CapsLock is an old and known matter. No fix for it.

Try using the forum Search facility or browse through this specific Lenovo section.. Thank you. https://osxlatitude.com/index.php?/topic/9687-help-me-install-sierra-on-z51-70/

Moving to the right place...

You're using the HiRes Capri layout 0x01660004, therefore you need to patch the Capri framebuffer kext as per the recommended setup in your Clover config. See here for details. As detailed in my E6230 guide, DW380 will work once you inject its device id in the Broadcom transport kext. This can be done either through FakeSMC (you add the necessary entry to the kext's Info.plist) or through direct patching of the IOBluetoothFamily PlugIn kext. Patching principles are explained here. An example of how you can inject info through FakeSMC is available here. This make for a much better and far more sustainable patch than direct Broadcom transport kext patching which would need to be repeated after each update and/or upgrade. NB: Remember to compress (zip) files before you attach them. JPEG can be attached "as is", they're already compressed.

Make sure you've setup your system for HiRes LCD: 1) Capri layout 0x01660004 2) DualLink set to 1
