Trying to force update_dyld_shared_cache but having some errors
I am trying to force the update of my dyld shared cache using the command
sudo update_dyld_shared_cache -root / -force
But after a while I see a bunch of errors like this, related to spindump:
update_dyld_shared_cache[719] : Unable to unlink //var/db/spindump/OLDDSC-E2D77243-3FD9-32E5-AE64-3506904D5579: 1 Operation not permitted
How do I fix this?
I am on El Capitan.
What fixed it for me was
update_dyld_shared_cache -debug
This is what you should see
update_dyld_shared_cache: adding root: /System/Library/...
...
...
update_dyld_shared_cache: /var/db/dyld/dyld_shared_cache_i386 is up-to-date
update_dyld_shared_cache: /var/db/dyld/dyld_shared_cache_x86_64 is up-to-date
to be sure it works I run
update_dyld_shared_cache
a second time
Reboot your mac in recovery mode (https://support.apple.com/en-ca/HT201314), Open Terminal there and type
rm -rf /Volumes/<your_system_volume>var/db/spindump/*
After that restart your mac and repeat the operation
sudo update_dyld_shared_cache -root / -force
PS see detailed comment from @CharlieMonroe
the -debug flag on update_dyld_shared_cache doesn't do anything except provide more detail on the work that is being done -- that is makes the reporting more verbose.
I'd use: sudo update_dyld_shared_cache -root / -force
All systems provide 'errors' though these aren't issues, rather information on what can't be done or skipped because the way the module is implimented.
These are the typical 'errors' for a heathly system:
