-> moved to Monterey beta section where this thread belongs; please make sure to post in the forum's relevant sections. Thank you. With regards to your observations and experiments: 1) Monterey is at initial 1st Developper Preview stage at this point of time 2) Monterey carries no native support for HD4000 graphics that have now been officially dropped from macOS 3) HD4000 can only be supported after patching Monterey beta1 with tools such as OCLP v0.1.7 and later 4) Automatic login must be enabled after 1st boot and until you patch Monterey, failing what you end up with the graphics initialisation failure loop you currently experience I had already mentioned this in my Monterey beta1 thread posted in this very section. Please note that you're highly likely to experience reduced performance, very high temperatures and regular crashes with Monterey; it's very early stages and it does not run too great on dropped Ivy Bridge/HD4000 platforms for the moment. Best is to wait for subsequent beta versions and further development on the patching side.

Further to the announcement made at today's WWDC event, Apple released the 1st beta of macOS 12 Monterey to developers. It can be downloaded after installing the latest devs Beta access utility available in all good places such as here or by using the associated InstallAssistant as stated here. On the bad news front, not much to say other than support for Ivy Bridge HD4000 is dropped as could be expected given that it remained unofficially supported in Big Sur. On the good news front, we'll note that: although support for pre-2015 Haswell-based iMac/MacBook Pro/MacBook Air models appears officially dropped, support for Haswell-based Mac mini Late-2014 has remained and with it, support for Haswell graphics! support for nVidia Kepler card has remained too! Other good news is that Monterey beta1 installs with the exact same settings as Big Sur. Pending the usual necessary kexts' update, the only additional requirements I found for my Skylake/HD520 Latitude E7270 were: Lilu's -lilubetaall boot arg to avoid system reset. WhateverGreen's -wegbeta boot arg to avoid KP on wake. Other than that, nothing at all and I was even able to install, boot and run Monterey beta1 with Clover r5133. Ace! So far, but it's only been a very very short time, everything works fine and as per Big Sur. Installation was much much quicker than what I have experienced with all versions of Big Sur and it only required 2 x reboots. Bootloader recommendations: Clover r5133 or later OpenCore 0.6.9 or later

Lilu & PlugIns now updated to support macOS 12 Monterey. Available off the Dortania Opencore kexts repo. After updating the kexts, the beta boot args are no longer necessary. Early reports of problems with Bluetooth. Remove your BT injectors and patched kexts if you encounter issues.
