^Title :P

@CokePokes nice work, dumping dyld_shared_cache worked perfectly on my 11 Pro Max. Although to get it to build on modern a modern Theos setup required that I update the makefile, I thought if anyone else comes across this, I could insert the fix here in this thread;

DEBUG=0 GO_EASY_ON_ME=1

TARGET = simulator:clang:11.0

TARGET = macosx

TARGET = iphone:clang::6.0

export TARGET = iphone:clang:11.2:9.3 export ARCHS=armv7 arm64 arm64e

export ARCHS=x86_64

include $(THEOS)/makefiles/common.mk TOOL_NAME = classdump-dyld classdump-dyld_FILES = main.xm classdump-dyld_LDFLAGS = -Wl,-segalign,0x4000 classdump-dyld_CODESIGN_FLAGS = -Sent.plist include $(THEOS)/makefiles/tool.mk include $(THEOS)/makefiles/library.mk SUBPROJECTS += classdumpdyldlib include $(THEOS)/makefiles/aggregate.mk

Great work again!

Hi, could you create a deb with this forked fix? Thanks very much

@demhademha I just changed the identifier to daniel.classdump-dyld so it wouldn't keep telling me an update was available from limneos's repo, but it's completely identical other than that https://www.dropbox.com/s/b6r3pexnn0u5n07/daniel.classdump-dyld_1.1-2_iphoneos-arm.deb?dl=0
