Nah, I think he's incorrect. The reason being that the W-2135 is only 6(12) cores, where the W-2140b and W-2145 are 8(16), and the W-2150b and W-2155 are 10(20). However, I would expect that the W-2145/W-2155 would be better than the W-2140b/W-2150b respectively or why not name the cpu the same (or to even differentiate that it was mac-only with just the b)? So the higher clock speed for the W-2145 and W-2155 makes sense, they have similar turbo freqencies (also with the W-2135 but it has less cores, specifically the third number multiplied by 2 is the core count). Comparing the W-2170b and W-2175, or the W-2191b and W-2195, they are the exact same it appears (though I have a feeling they are not because again why would they make two different versions of the same chip with just a different identifier?). The models then all get slower as the identifier increases as the TDP stays the same (140W) but the core counts increase, meaning there is less power for each core. The thing to note is that all of the mac-only models were announced in june of 2017 when they introduced the imacpro, but weren't released until the imacpros actually came out in december. The other models were announced and released all on the same day in august 2017. This is actually probably a misleading thing though, as most likely the mac-only models were engineered first, much sooner than june and shipped to apple because they then needed to build the imacpro, which needed to be ready by june (because that's when they announced and showed it) but weren't actually released until december. So I think they had the chips already at that point in june, putting the manufacture date at the very beginning of 2017 or end of 2016. Why does intel then wait until august 2017 to announce the consumer available w series, only as the series is released? They probably weren't engineered until early-mid 2017. I would think that the mac-only models are actually probably the specs apple wanted and the others are what intel thought consumers would buy at specific price points after having engineered the models for apple, not wanting to waste a process as they could sell more commercially than to apple alone (not to mention they probably get more money from consumers than from apple per cpu). You can also look that they did not release any W-216X or W-218X cpus (which would be 12 and 16 cores and no other models in the W series have those core counts). Why also name the one randomly W-2191b when the other mac-only models end in 0? Maybe they intended to release those models but ended up changing their minds and there would have been a W-2190 which would be slower than the W-2191b (or maybe they still may release them). After reading what he says in his post, he even appears to state a better reason than heat for the difference, they actually are different and have integrated graphics. Then he states the integrated graphics are disabled by the OS, more implication here on my part, but I imagine this is what is causing the issues. On a mac, the integrated graphics are initialized by the firmware but then disabled by the OS, this is perfectly acceptable. On non macs, the integrated graphics are not initialized but then the OS tries to disable the integrated graphics, this is an issue, especially when there is no integrated graphics (not using a mac-only model). The firmware for C422 probably doesn't even attempt to initialized integrated graphics because well it doesn't actually support integrated graphics (https://ark.intel.com/content/www/us/en/ark/products/126691/intel-c422-chipset.html). This is an interesting read (https://www.pcgamer.com/heres-what-you-need-to-know-about-kaby-lake-x/), maybe the mac-only models are actually re-purposed skylake cores with integrated graphics as well that can't actually work because of the C422 chipset not supporting integrated graphics. I wonder if the other models are actually a different process then or not... Lots of information here, and some speculation..... I think you have discovered you have two ways to configure to get working system and power management with the w series, fakecpuid + patch _xcpm_pkg_scope_msrs, or bootstrap patch + frequency vectors. EDIT: Oops, I meant skylake for the w series, not kaby lake, lol.

Magari un semplice grazie farebbe sicuramente piacere a chi aiutandoti ti ha permesso di installare

Spoke with you on Discord and figured out you were using a tonymac product. That is not supported here. The driver you're using also has not been developed since El Captain. I'd suggest you pick up a card that is supported native... https://www.amazon.com/Inateck-Express-15-Pin-Connector-KT5001/dp/B00FPIMJEW/ref=sr_1_3?keywords=Inateck+PCI-E+to+USB+3.0&qid=1555090828&s=electronics&sr=1-3

yes, I have only Radeon VII, both iMac18,3 and iMac19,1 works, natively support but only for 10.14.5 beta.

No, clover does not create an ESP. There is no ESP on an MBR partition map disk, you need to have a hybrid GPT disk in order to legacy boot from the ESP. You just want to use the installer, do not choose install Clover to the ESP, but choose Boot Sectors > Install boot0af in MBR and Clover for BIOS (legacy) booting > Clover EFI 64-bits SATA. EDIT: Also make sure that Clover for UEFI booting only is unchecked first. And you probably want Install RC scripts to target volume. You then may want optional RC scripts or the preference pane, they are optional though.

Hi @apianti I really enjoyed reading this post (Bachelor degree level), and I very much appreciate your efforts to try to explain and shed some lights over this complex stuff. I think the conclusion of all this is that we, for the moment, have to live with a "non-native" processor, and try to do the best of the situation and use the tools that is available. As long as we have a working_xcpm_pkg_scope_msrs patch everything is working like a charm. Thank's again @apianti for your hard work with Clover and give us a hint if you have any news regarding our specific problems.

Well, the last supported version is High Sierra 10.13.6 but you may get random glitches unless you have a non AUO LCD But I am running Mojave 10.14.4 with some extra hacking but. that may be the end of road.

I'm NOT sure how "permanent" InsanelyMac Sound solutions are for Onboard Sound... I found, (from the other place), that sound disappeared after about 4 Reboots... Hence my spending $10 on the SabreNT. Try what you have since @Hervé got your Onboard Sound working... IF; however, it craps out after a few reboots, (like at the other place), then invest in the USB Audio Device. Good luck.

Glad I could help. Yes, Amazon is where I got mine from. Also, since it's just sound, you don't need to use a USB 3.0 Port for it, either. Plug it into one of the USB 2.0 Ports on the Back Plane of the MOBO.

Hi @Installus, Welcome to InsanelyMac from another Refugee from that same Realm. My remedy for sound was to buy a USB Audio Device, (SabreNT - less than $10), which was Plug and Play - NO Drivers needed, NO Kexts to install. MOST USB Audio Devices work OOB, but I do HIGHLY recommend SabreNT. Good luck.

On Dell Optiplex 790 to make booting UEFI and to have Clover GUI really good you need this Driver64UEFI CsmVideoDxe-64.efi The screen is identical as booting ESP legacy

I Have UHD 630 on CPU I7 8700 . Post Clover and Ioreg to try to activate UHD 630 graphics on 10.14.x
