Administrators Hervé Posted June 7 Administrators Share Posted June 7 As stated and shown at Applelife & InsanelyMac, works with OpenCore + AvoidRuntimeDefrag=No. Not sure about the need to add -lilubetaall boot arg. Boot loop with Clover (r5142) for the moment on my E7270 Skylake laptop with same config as used for Big Sur and Monterey, only SMBIOS changed to MBP14,1. I confirm that support for Haswell, Broadwell and Skylake iGPU is dropped, the only graphics framebuffers available in /S/L/E being KBL, CFL and ICL ones. For AMD, all GPUs older than Polaris generation are dropped. AppleIntelCPUPowerManagement is dropped too, something we still required on good old C2D, C2Q, 1st gen Core, Sandy Bridge and Ivy Bridge platforms so that could add a few nails in their coffin. 3 Link to comment Share on other sites More sharing options...
Administrators Hervé Posted June 7 Author Administrators Share Posted June 7 Ventura b1 installation completed after updating Clover to r5146. But E7270 struggling to even complete 1st boot setup due to lack of graphics acceleration so I can't even finish that and reach Ventura desktop. So, unless you have a Kaby Lake/HD615 laptop minimum, no point wasting your time until an eventual patch is made available... 1 Link to comment Share on other sites More sharing options...
Administrators Hervé Posted June 8 Author Administrators Share Posted June 8 As suggested by @aben at IM, I experimented with KBL framebuffer settings on my Skylake/HD520 Latitude E7270. I also updated all add-on kexts to latest versions (Lily & PlugIns) and replaced good old ACPIBatteryManager + FakeSMC by their VirtualSMC equivalent. This allowed me to boot Ventura b1, complete 1st boot setup and reach desktop; the laptop still freezes shortly afterwards so something's still iffy but at least I can boot and with apparent full graphics acceleration: Spoiler I don't know about older generations but there seems to be hope for Skylake laptops. 3 Link to comment Share on other sites More sharing options...
Administrators Hervé Posted June 8 Author Administrators Share Posted June 8 'working on my Clover setup and manage to significantly reduce the freezes though not entirely. Sometimes, system still freezes a few seconds after reaching desktop. But it seems to run pretty stable most of the time. Graphics acceleration is acceptable at this stage though not bug free: occasional slow movements on screen and some contents leftovers after closing a window for instance. Or unrecoverable limping system of complete freeze after attempting to watch a Youtube video in Safari. But, hey, what can we expect out of a KBL framebuffer on a Skylake system? Other than than, everything appears to work properly on the E7270: graphics acceleration with some defects and reduced/degraded performance brightness control touchscreen HDMI output mini-DP output audio (incl. DP audio) LAN wireless & Bluetooth (BCM9460CS2) touchPad USB ports sleep & wake SD card reader Whether this ends up sustainable in the long run for Skylake laptops remains to be seen but you never know... Is it usable for the time being? Clearly not. Edit: Instant wake issue on sleep and HDMI output now sorted.

ativi Posted June 8 Share Posted June 8 @Hervé Great to hear of progress being made with Skylake Notebook, I am using opencore 0.8.1 been able to boot up into macOS Ventura beta recovery, but get stack or freezes on 16 minutes remaining during first install screen. What may be the problem, my Hardware is Dell Latitude E7470 with Intel Core i5 @2.40Ghz, I know my Hardware share almost same Hardware configuration as yours. Any suggestions from you will be helpful. Thanks in advance Link to comment Share on other sites More sharing options...

With KBL 0x591B0000, only the external output ports definition (HDMI + DP) differ and, if need be, we can easily inject that through properties injection in the bootloader's config. I've also experimented with the SKL injector posted by PMHeart here at IM; the E7270 certainly appears to run Ventura much more stable but graphics defects are, imo, worse, especially in Safari. On the other hand, it's Ok with Chrome so I would recommend using that for the time being. Revised Clover pack #2 posted above. 2 Link to comment Share on other sites More sharing options...
Administrators Hervé Posted June 11 Author Administrators Share Posted June 11 Why setting AvoidRuntimeDefrag to No was required to boot Ventura beta1 until now: https://github.com/acidanthera/OpenCorePkg/pull/357 Link to comment Share on other sites More sharing options...
Administrators Hervé Posted June 19 Author Administrators Share Posted June 19 This revised version of Clover r5146 restores full stability in Ventura beta1 with AvoidRuntimeDefrag quirk set (failing that systems boot but rapidly freeze). The OpenRuntime Clover module was fixed. Thanks to developper @Jief_Machak for the updated build. Clover_r5146beta-48be65956.pkg.zip This follows findings posted at InsanelyMac stating that older version such as r5137 could boot Ventura without subsequent freeze. Revised pack #3 posted above accordingly. Edit: Fixed lack of HDMI output by changing KBL framebuffer 0x591B0000 to 0x59160000 which has suitable output ports definition. Revised pack #4 posted above accordingly.
