Was this after stage 1 where the Apple logo and progress Bar with a timer showed up? If so, this is an ongoing issue with the T2 and currently @zkennedy137 is solving it.
@Pedroinsti ·
@sonimcrinebru-art when the bar started loading after 3 min it said that
@sonimcrinebru-art ·
@Pedroinsti
Then that is a issue ongoing on T2 Macs that @zkennedy137 is working on.
@Pedroinsti ·
@sonimcrinebru-art okey thank you when its fixed could you tell me?
@sonimcrinebru-art ·
@Pedroinsti
You can see this issue's progress in #519.

@Pedroinsti No, unfortunately this update (
4.0.0.190008.2) does not fix your Stage 2 installation error yet.Here is why:
4.0.0.190008.2updatedPatcherSupportPkg, improved post-install kernel cache rebuilding, and fixed Wi-Fi Darwin version checks. It does not yet include a bypass for the Stage 2 installer failure.MacBookPro15,2) fails in Stage 2:During Stage 2 (about 3 minutes into the installation bar), macOS runs
OSIUpdateFirmwareElementto check and stage BridgeOS firmware for your T2 chip. Because Apple dropped 2018 Macs from Tahoe, the installer does not contain signed BridgeOS firmware payloads for your model, causing the installer to fail and abort with "macOS had an error installing".This is the exact issue we are actively working on and solving right now in Discussion #519. We have already identified the exact selector (
-[OSIUpdateFirmwareElement runReturningError:]) and successfully verified a working bypass in testing.Keep an eye on #519 — once the Stage 2 bypass is packaged into an OCLP build, 2018 T2 Macs like yours will be able to complete the installation smoothly!

I cannot guarantee this will work as I haven’t tested it. So I tried to get Claude to update the kext to Hooke the osinstallersetupd process and inject the value 1 for OSIUpdateFirmwareElement=1 it refused. So
I took the repo link to SpoofVMM.kext and asked Gemini it happily ablidged. Now that being said again do not treat this as a fix as I have not tested it. But here is a zip containing the new source code that one of you could try to test if you get the chance before I get home from work.
SpoofVMM_Plugin_Source.zip
@Pedroinsti ·
@albert-mueller the new updates fix that?
@zkennedy137 ·
It is an attempt to, like I said I haven’t actually compiled the kext and tried it etc. but if that @Medelcartelinc discovered is the issue it should help I think.
