Wowfunhappy Posted October 26, 2015 Share Posted October 26, 2015 I can't personally recall a time in recent memory when Apple has had a custom intel chipset designed for one of their computers. We know the iMac is Skylake and Z170 is the only thing that supports Skylake atm.

Adventuro-3 Posted October 27, 2015 Share Posted October 27, 2015 I can't personally recall a time in recent memory when Apple has had a custom intel chipset designed for one of their computers. We know the iMac is Skylake and Z170 is the only thing that supports Skylake atm. True in the open market, but H170 or something like that is coming soon. It wouldn't be out of the question for Apple to make a deal to get these chipsets (iMac = MILLIONS of computers) before they are released to the general public. Maybe not custom chips, but normal production chipsets before they are available to us. 1 Link to comment https://www.insanelymac.com/forum/topic/308683-clover-with-mac-skylake-cpu-support/page/2/#findComment-2182801 Share on other sites More sharing options...
cwestpha Posted October 28, 2015 Share Posted October 28, 2015 There are many chipsets for skylake, don't assume till you know for sure, could be h170 or something else even. Comming soon? H170 is out, been out for a while, long before iMac came out in fact. Pls show me proof its z170 and i will gladly shut up. Curently available chipsets being used on mobos are Z170, H170, H110 and B150 Just need someone with access to said high-end model for pulling the IDs. However I doubt it is 110 as it only supports a single pair of memory, high-end imac has two pairs (4 slots). Also the 110 can only drive 2 displays at once. Q/B line could be, but I doubt Apple would be interested in the business stuff they have (extra money on the low end and redundant on the high end). Most likely Z170 or H170 for the top of the line. I would think on the high-end imac they would want the extra pcie lanes coming off of the Z170 and more flexibility in splitting the lanes. Then again Apple didn't go Thunderbolt 3 so there should be plenty of bandwidth to keep the TB 2 ports fed + all I/O without any major constraints. *shrugs* Link to comment https://www.insanelymac.com/forum/topic/308683-clover-with-mac-skylake-cpu-support/page/2/#findComment-2183234 Share on other sites More sharing options...
TheRacerMaster Posted October 29, 2015 Share Posted October 29, 2015 Fairly certain at this point that iMac17,1 is using Z170 chipset. LPCB device ID (from iMac17,1 IOReg dump, see bottom of page) is 8086:a145, which matches Z170 LPCB device ID. Matches up with previous iMacs (iMac12,2 used Z68, iMac13,2 used Z77, iMac14,2 used Z87, iMac15,1 used Z97, etc.). 1 Link to comment https://www.insanelymac.com/forum/topic/308683-clover-with-mac-skylake-cpu-support/page/2/#findComment-2183242 Share on other sites More sharing options...
cwestpha Posted October 31, 2015 Share Posted October 31, 2015 Played around with the 10.11.2 beta and I can now get past a lot of the issues but the PCH, as stated before, just isn't being autodetected and configured resulting in issues with AHCI SATA. USB system is also throwing errors left and right. Apple must have changed something with how the PCH and some things hanging off of it are detected and configured as PJALM pointed out. Just giving it the Device IDs still gives wonky behavior. Using the board-id: Mac-65CE76090165799A – Model: iMac17,1 [(Retina 5K, 27-inch, Late 2015) / Core i7 4.0GHz] for basis of SMBIOS joy.

scj312 Posted November 6, 2015 Share Posted November 6, 2015 Has anyone tried with PCIe M.2 storage? Seems like that would bypass any SATA issues.

TheRacerMaster Posted November 6, 2015 Share Posted November 6, 2015 All USB/storage issues are fixed with APIC edits (either in BIOS or kext patch [discovered by Pike]). 1 Link to comment https://www.insanelymac.com/forum/topic/308683-clover-with-mac-skylake-cpu-support/page/2/#findComment-2185860 Share on other sites More sharing options...
blahblah31415 Posted November 6, 2015 Share Posted November 6, 2015 I, too have been trying to get this working. Also stuck at the "still waiting for root device" with a prohibited/blocked logo, and the rest of the text is jumbled. I'm trying to get this working on an msi laptop however, and this is about as far as i can get. I've tried disabling things in the clover boot menu with no luck. Anyone have any ideas on how to fix this?
