USB Creator Issues on Mac OS 10.15 Catalina


Recommended Posts

I spent all morning trying to make a bootable disk on my mac and failed, disabled sip, added full disk acces.  The disk is created but is not bootable.

 

If I try manually, using the script I get errors from syslinux abount being able to unmount.  If I run syslinux myself manually (same command that the script does) syslinux doesn't error and says it completed corretly, but again, the disk is not bootable.

 

Eventually I booted into Windows, ran the utility there and it worked first time.

 

It would be nice to have prepared images available so that we can use other software like etcher which has never failed me.

Following my USB failure last night, I tried to create a new USB key under Catalina and again was unsuccessful, disk was not bootable.

 

The tool or make_bootable_mac script didn't work, I've disabled SIP.  When I run the script, I get:

/dev/disk5
 61.5GB

"/dev/disk5s1" unmounted successfully.
/dev/disk5s1: invalid media signature (not an FAT/NTFS volume?)

INFO: the Unraid OS USB Flash drive is now bootable and may be ejected.

 

Unsurprisingly the disk isn't bootable.  I managed to borrow my daughters windows laptop this morning, used the USB creator and copied across a backup of the config and the disk booted up straight away, no issues.

 

We desperately need another solution to this, Catalina has been out a while and the USB creator is still broken.

 

If you can't fix it (and even if you can) in the mean time can you supply an img that can be written using balena etcher so that there's an easy way of creating a working USB stick with no fuss under Catalina.

Did you disable SIP?

Neither the USB creator app nor the manual install script is working on MacOS Catalina 10.15.4. SIP disabled, and the app has full disk access. USB drive is formatted FAT32 and named UNRAID. The script make_bootable_mac doesn't even look like it would work right -- it appears to be copying files to/from the wrong places. I'm pretty good with this stuff, but it's extremely difficult (impossible?) to make a bootable USB stick on a Mac running Catalina right now. I eventually gave up and used my kid's Windows box to make the USB drive. I'm still really looking forward to bringing my first unRAID box online!

I am evaluating Unraid and the USB creator is broken on Catalina (10.15.5) and the alternative shell copy and run command mode is riddled with errors. Not the start I was hoping for, it feels like building my Hackintosh.... Adding my 2 cents here:

The USB stick does seem to boot but I am not exactly having the warm fuzzies for my first boot.

 

Any solution here? (beside pulling out a windows machine to make a bootable USB stick)

Any updates on this condition?

 

I got this message:

Your flash drive is corrupted or offline. Post your diagnostics in the forum for help

 

And when I try to use the Creator:

“Unraid USB Creator.app” can’t be opened because Apple cannot check it for malicious software

This software needs to be updated. Contact the developer for more information."

I needed to use the unRAID creator tool 5 days ago, January 10 and received the same error message. How is this constantly being ignored...?

@jonp

I’m tagging LimeTech on this. They may not even be aware.

 

The manual method should still work though.
