#DISABLE MAC SECURE BOOT 64 BIT#
Misc > Security > ApECID: to use personalized Apple Secure Boot identifiers and to have Full Security when paired with SecureBootModel.įor ApECID value, you must get a 64 bit integer randomly generated in a cryptographically secure way. If you have Python 3 installed, you can use this command in Terminal: Misc > Security > SecureBootModel: to set the Apple Secure Boot hardware model and policy SecureBootModel equate to Medium Security, for Full Security you must use ApECID Misc > Security > DmgLoading: to set load policy with DMGs in OpenCore it can be Any (boot fails if Secure Boot is enabled), Signed and Disabled (both support Secure Boot)
#DISABLE MAC SECURE BOOT HOW TO#
How to get Apple Secure Boot in the Hackintosh? OpenCore provides 3 keys to enable Secure Boot: For example, j140k will filter 10.13 and lower, j152f will filter 10.14 and lower, x86legacy will filter 10.15 and lower.

Of course, you can also set Secure Boot Model to the value, from the list above, that corresponds to the macOS version you want to boot (example j160 for macOS Catalina 10.15.1). If you are suspicious of old operating systems, you can always put the model that only supports the versions you need of macOS and not the previous ones. Note: iMac19,1 (March 2019 - Minimum macOS 10.14.4) isn't in the list because it has no T2 chip. X86legacy - Macs without T2 chip and VMs. Valid values in OpenCore 0.7.2 (all are models with T2 but x86legacy and disabled):ĭefault - Recent available model, currently set to x86legacyĭisabled - No model, Secure Boot will be disabled *According to Apple, these Mac computers have Apple T2 security chip: Users who don't want to have Apple Secure Boot for any reason can set SecureBootModel=Disabled, even in Big Sur and Monterey.

Systems older than macOS 10.13.2 must set SecureBootModel=Disabled J137 is the recommended value for macOS 10.13.2 through 10.15.x X86legacy (Default now) is designed for machines without T2 chip* with Big Sur and especially Monterey if we want to have Apple Secure Boot (minimum macOS 11) In OpenCore 0.7.2, failsafe value for SecureBootModel remains Default, but this value sets Apple Secure Boot hardware model as x86legacy, new value (not existing in previous versions) that corresponds to macOS 11 Big Sur and 12 Monterey on hardware without T2 chips. In OpenCore 0.7.1, failsafe value for SecureBootModel is Default, this value sets Apple Secure Boot hardware model as j137 (iMacPro1,1 December 2017 macOS 10.13.2). This means that macOS versions older than 10.13.2 cannot be installed with this SecureBootModel value. This key has been changed in OpenCore version 0.7.2. OpenCore has a SecureBootModel key that adjusts the Apple Secure Boot mode to make it similar to Macs. There are no requirements on the boot operating system. No Security: other systems or versions different from those mentioned in the secure options are allowed. Lets you boot any signed version of macOS in which Apple has ever trusted.

Medium Security: Checks that the installed version of macOS is legitimate but not the integrity of the system. If the check fails, the system offers to reinstall macOS or boot from a different disk. It also checks the integrity of the installed version. If this check fails, macOS won't boot.Īpple Secure Boot only works during the boot process, once macOS is running it no longer performs any function.įull Security: Only allows to boot the installed operating system or another signed version of macOS in which Apple currently trusts. I'm also interested in the relationship between BIOS secure boot and OpenCore secure boot.Īpple Secure Boot is the technology used in Macs to verify the integrity of the operating system at boot: boot loader > kernel > snapshot of the system volume. This post is based on this guide next to my personal experience. Note: it is highly recommended to read the Dortania guide where this process is explained in detail.
