Subject: [BUG] Enabling EFI runtime services causes panics in the T2 security chip on Macs equipped with it.
Date: Thu, 9 Dec 2021 07:05:35 +0000	[thread overview]
Message-ID: <74ACDCF3-6996-4CB4-8899-A625D154FB0C@live.com> (raw)

On enabling EFI runtime services on Macs with the T2 security chip, kernel fails to boot due panics in the T2 security chip. Using efi=noruntine (or noefi) as a kernel parameter seems to fix the issue. Also, making NVRAM read-only makes kernels boot. A fix for that would be appreciated.
