Since updating my Mac running Snow Leopard to 10.6.1, I’m seeing the following message in the Terminal at least once after running every command:
dyld: shared cached file was build against a different
libSystem.dylib, ignoring cache
Someone said online that you can clear the cache using the following command:
sudo update_dyld_shared_cache -force
That returned the error:
update_dyld_shared_cache failed: vm address 0xFEEDFACE not found
in /System/Library/Frameworks/Accelerate.framework/Versions/A/
Frameworks/vecLib.framework/Versions/A/libLAPACK.dylib
I was hoping to post a solution to the problem for other people, but I haven’t solved it yet! So if you have any ideas, please post a comment.
Update: Looks like the library that’s preventing me from updating the dyld cache is in the hardware acceleration framework. Here’s one proposed solution, which involves moving the offending framework, running update_dyld_shared_cache and then moving the framework back. I’m not entirely comfortable with that.

The clearing of the cache worked for me. Thanks!

Work for my … many thanks !!

I’m having the same problem as you (and have been for some time now), in that “sudo update_dyld_shared_cache -force” (even after safe booting) doesn’t fix the problem. Most irritating.

Under 10.6.2 Restarting the computer in Safe Boot mode deletes the dynamic-loader shared cache. If you suspect the shared cache is somehow corrupt, you can run: sudo update_dyld_shared_cache -verify
which re-creates the cache and compares the result with your actual cache file. The launch time of Cocoa programs has been improved by caching some Objective-C runtime fix ups in the shared cache. Thus the Objective-C runtime has less work to do during launch. Be PATIENT it could take up to 4 to 6 minutes on some system
