Correct. I'd like to proxy only some requests. Or at least, to be able to resolve DNS request within the extension (if I do so currently, the request I made within the extension using res_send is forwarded to my proxy…)

Thanks a lot! This is working.

We have reports of several of our customers having this issue. Have you any idea of what could cause this problem? This folder is protected by SIP so no one except Apple should be allowed to modify flags of this folder, right?

I have a slightly different problem: I can't make replication work. sudo asr restore --source / --target /Volumes/BB --erase Validating target...done Validating source... Source volume format on device "/dev/disk4s5s1" is not valid for restoring Could not validate source - Permission denied or sudo asr restore --source /dev/disk4s5 --target /dev/disk5s1 --erase Validating target...done Validating source... The source volume cannot be restored because it has a broken seal Could not validate source - Invalid argument Indeed, APFS seal seems broken on my system volume. But I don't know what could have broke this seal, how to fix that, and why it prevents completely volume replication from working

Thanks sux2mfgj. I just installed beta 7, and there are some improvements: my startup disk is now correctly sealed. I tried with "toSnapshot" option on beta 7, and it's better: I can see a different error :) Validating target...done Validating source...done Couldn't set up partitions on target device - operation AddAPFSVolumeToContainer, line #5330 - error 49231 I also noticed that other vendors have the same problem. Let's hope it will be fixed for GM.

Beta 8 is better. I can finish the apfs operation: Password: Validating target...done Validating source...done Replicating ....10....20....30....40....50....60....70....80....90....100 Replicating ....10....20....30....40....50....60....70....80....90....100 Restored target device is /dev/disk3s2.

In beta 9, asr did almost work. By almost, I mean that the command succeeded, but the resulting volume is still not bootable. But there is a regression in beta 10 : the command failed. I tried several options, but it's ending on a failure on: "Couldn't embed the APFS EFI driver - erreur 49174" I hope this is not the GM…
