recover media for macos can't find network servers

I didn't know there was a mac forum. reposting here
 

I made a bootable recovery USB for my macos Catalina. It will boot just fine, but it can't restore. It has no network connections pre-installed (like the windows one does), and I can't connect to my local SMB server to restore from it. The mac does happily back up to this server every day, so clearly true image knows about the connection, knows the password and everything. 

Not only is the connection not there like I expect it to be, I can not establish an smb connection. I tried smd://servername/folder as well as smb://ipaddress.

So - my questions: should be connection used for backup be configured in the recovery media already?
I'm trying to connect using wifi. Does the recovery media not know about wifi?

Thanks!

Hello Bruce,

the connection should be established either via Choose Network -> Connect to SMB share (e.g. smb://epic/share) or as a workaround: go to Local Storage -> Shares 

If the share is still not detected, I'd suggest opening a support ticket, so that our engineers can look into the situation and help.

I have the exact same issue with the the recovery USB created by Acronis.  It doesn't connect to SMB shares.  If I try IP or hostname, it should be prompting for a username and password.  It does not.  It just hangs.  Its not a network issue because I can access the same share through a terminal window in the same recovery USB.

But this is not the only issue with the Acronis recovery USB.  The other problem is that you have to turn off boot security on your Mac and leave it off in case you have a disk failure.  Otherwise, you cannot boot the Acronis recovery USB because its not signed.  The problem with turning off boot security is that it puts your computer and privacy at risk.  In addition, when this is detected by macOS , Apple disables Apple Pay and all the credit cards in your wallet when boot security is set to none.

To work around these problems, I added a second, small macOS installation to my recovery USB.   This allows me to leave boot security turned on until I need the USB.  Then I use the macOS installed recovery partition of the USB to turn off security.  After that, I boot the second copy of macOS and copy the Acronis backup from my file server to the local USB.  Then I reboot into the Acronis recovery partition of the USB and restore from then backup I just copied.

Its silly to have to go through all of this.  But, it is what its is.

Hello Frank,

thank you for sharing your solution with the community! 

Regarding 

The other problem is that you have to turn off boot security on your Mac and leave it off in case you have a disk failure.

We've discussed this issue internally and according to my colleagues, the behavior might differ depending on the hardware. If you have some time for investigation, we'd recommend opening a support ticket, so that our engineers can check why booting from the USB requires turning off the boot security on your Mac. Thank you!

Yes.  It does depend on hardware.  If you have an older Mac that does not have the T2 chip, there is no prevention from booting an unsigned and thus untrusted OS.  The newer Macs, such as mine, have the T2 chip and by default have the desired security check enabled.  When the security check is enabled, unsigned and thus untrusted OS's such as the Acronis Bootable Media is not allowed to boot the Mac.  If Acronis doesn't want customers to have to lower their security in order to use the Acronis Bootable Media, Acronis will need to sign the bootable media when its created.  At a minimum, Acronis should at least remove the restriction where Acronis won't even allow you to create the Acronis Bootable Media unless the setting is turned off.  With this restriction, customers are likely turning the setting off and leaving it off which puts their computer and data a risk.  A better approach would be to allow them to create the media with the setting on and then include documentation that states the media cannot be used unless the setting is turned off.

 

Here is Apple's list of computers that have the T2 chip:
