Kernel
New Features
The
kern
limit has been increased, allowing programs to receive longer argument lists. (48661669).argmax Darwin
kevent
now allows non-parent processes to register forNOTE
, which delivers the same values as the_EXITSTATUS wait()
family of functions in the event data. Refer to thewait4()
man page for more information. This event is subject to the following security checks:The requesting process is allowed to send signals by sandbox restrictions.
The requesting process and the target process are running as the same user or the requesting process has root privileges. (58134463)
Known Issues
Installing a new kernel extension requires signing in as an Admin user. You must also restart your Mac to load the extension. Kernel extensions using certain deprecated KPIs won't be loaded. For more information, see Deprecated Kernel Extensions and System Extension Alternatives . (55068348)
Workaround: During development, you can temporarily disable System Integrity Protection to allow these deprecated kernel extensions to load.
Remote panic dumps aren't currently available. (57915324)
New in macOS Big Sur 11 beta, the system ships with a built-in dynamic linker cache of all system-provided libraries. As part of this change, copies of dynamic libraries are no longer present on the filesystem. Code that attempts to check for dynamic library presence by looking for a file at a path or enumerating a directory will fail. Instead, check for library presence by attempting to
dlopen()
the path, which will correctly check for the library in the cache. (62986286)kmutil install
might fail to build a development kextcache. (63772702)Workaround: Copy the release
.elides
to the locations of the development.elides
:sudo cp /path/to/livemount/System/Library/KernelCollections/BootKernelExtensions.kc.elides /path/to/livemount/System/Library/KernelCollections/BootKernelExtensions.kc.development.elides sudo cp /path/to/livemount/System/Library/KernelCollections/BootKernelExtensions.kc.elides /path/to/livemount/System/Library/KernelCollections/BootKernelExtensions.kc.kasan.elides sudo cp /path/to/livemount/System/Library/KernelCollections/BootKernelExtensions.kc.elides /path/to/livemount/System/Library/KernelCollections/BootKernelExtensions.kc.debug.elides sudo cp /path/to/livemount/System/Library/KernelCollections/SystemKernelExtensions.kc.elides /path/to/livemount/System/Library/KernelCollections/SystemKernelExtensions.kc.development.elides sudo cp /path/to/livemount/System/Library/KernelCollections/SystemKernelExtensions.kc.elides /path/to/livemount/System/Library/KernelCollections/SystemKernelExtensions.kc.kasan.elides sudo cp /path/to/livemount/System/Library/KernelCollections/SystemKernelExtensions.kc.elides /path/to/livemount/System/Library/KernelCollections/SystemKernelExtensions.kc.debug.elides
Use only absolute paths with the
--volume-root
option ofkmutil
, and don't use a trailing/
. (63773848)Symbols exported by both xnu and Apple kernel extensions will change. Recompile your kernel extension with each update to macOS Big Sur 11 beta to ensure compatibility. (64262563)
Moving a kernel extension bundle out of
/Library/Extensions
might not completely uninstall it. (64331929)Workaround:
Remove the extension from
/Library/Extensions
.Boot to macOS Recovery.
Run Terminal.
Enter the command
kmutil trigger-panic-medic --volume-root /Volumes/<Your
.Volume Name> Restart your Mac.
Resolved in macOS Big Sur 11 Beta 3
No System Extension Updated alerts for third-party kernel extensions which are included in macOS should appear. (64337113)
After removing a DriverKit extension, a restart is no longer required. (63995046)
Adhoc signed kernel extensions now display the developer name in update dialogs and in Security preferences. (64215260)
Deprecations
Kernel extensions using certain deprecated KPIs no longer load. Refer to the support page . While macOS Big Sur remains in development, you can temporarily disable System Integrity Protection to allow these deprecated extensions to load. (55068348)
Localization
Known Issues
Certain languages might exhibit clipped or misaligned layout. (63105445)
Certain languages might display unlocalized text. (63105674, 64040564, 64045718)

Wallet
New Features in macOS Big Sur 11 Beta 3
Apple Pay support is now available to Mac Catalyst apps. Two methods have been added to existing delegate protocols. No changes are required for iPad apps, but one or both of these methods must be implemented when building for Catalyst. (64187739)
The first method is an addition to the
PKPayment
protocol:Authorization Controller Delegate presentation
. This method is required for Catalyst when usingWindow For Payment Authorization Controller: PKPayment
, becauseAuthorization Controller PKPayment
, unlikeAuthorization Controller PKPayment
, doesn't have knowledge of the window requesting presentation of the payment sheet. Pass back theAuthorization View Controller UIWindow
instance displaying the UI requesting the payment, for example,My
. This method is marked as required when building for Catalyst, but is otherwise optional.View Controller .view .window The second method depends on whether you're using
PKPayment
orAuthorization Controller PKPayment
. ForAuthorization View Controller PKPayment
, useAuthorization Controller Delegate payment
. ForAuthorization Controller(_: did Request Merchant Session Update:) PKPayment
, useAuthorization View Controller Delegate payment
.Authorization View Controller(_: did Request Merchant Session Update:)
This method must be implemented to request a merchant session via your server, and return it via the handler. This mirrors the security model used in WebKit, and replaces listing merchant IDs in the app's Apple Pay entitlements. This method in turn uses the following class to send back results:
API_AVAILABLE(macos(10.16), ios(14.0), watchos(7.0)) @interface PKPaymentRequestMerchantSessionUpdate : NSObject - (instancetype)initWithStatus:(PKPaymentAuthorizationStatus)status merchantSession:(nullable PKPaymentMerchantSession *)session; @property (nonatomic, assign) PKPaymentAuthorizationStatus status; @property (nullable, nonatomic, strong) PKPaymentMerchantSession *session; @end
