fine.

Hello,
Here is something odd. The install media I created does not show up in
system preferences as a startup disk. However I just did a restart and
held down the options key while it was rebooting. I had my sighted son
look at the screen and low and behold the USB Drive showed up there.
This is really odd.

Hello,
I just did the get info command on the volume. Yes it is bootable and
the others that were mentioned are set the way they should be. I have
tried it in both of the USB ports with the same results. It will not
show up in the startup disk section of system preferences. Hopefully
my new flash drive will be here soon to try.

Hi,
It sounds like the USB media that you're using does not support the
install media. Verify the state of the USB media by going into Disk
Utility, then selecting the "Install MacOS Catalina" item from the
selection table. Make sure to select the "Install MacOS Catalina"
volume, not the parent disk. Once selected, press cmd-i to Get Info
on the volume. Read through the various information items and make
sure that it says that the device is bootable. Some specific items
that are also important are if ownership is set to "No", File System
is "MacOS Extended (Journaled", "Yes" to writeable and "Yes" it can
be verified. If all that is good, but it is still not bootable, have
you tried putting the stick into a different USB port on your Mac?
Beyond these suggestions, I'd wait until your new USB comes from
Amazon and see how things proceed with that media.
I just tested the process using Terminal and it worked properly.
That is, the disk creation worked through it various copying,
installing, making bootable processes and completed. I then checked
in the Startup Disk pane and it was visible as a startup item.
Basically, if you don't see it as a bootable item from within the
Startup Disk pane, then using the option key method will not work
either. FYI, my media was a 16 GB stick with a 2017 MacBook Pro with
a brand new installer of 10.15.2 from Apple.
HTH.

Hello,
I did try using the terminal last night and still no go. The
process seems to finish okay but the USB drive still does not show
up in the startup disk section of system preferences. Even when I
unlock it so I can make changes there is only one option and that
is the hard disk. I am using the full Mac OS catalina installer.
Its an 8GB file in my applications folder. I did go into recovery
mode but I did not see anything that would enable me to boot from a
USB drive. I think that might be a thing you can do with Macs that
have the T2 chips only.

Easier? Maybe? I have used the app many times and it has never
failed. Matter of fact I retrieved the latest package from the app
store when 10.15.2 was released and I just created a new USB
installer with it using the app. And it shows up in startup. So I
do not think the terminal would fare any better.

Hi greg,
If the USb flash drive doesn't have a bootable package on it
Then no you wont see it in start up disks as there is nothing on
the USB device to start up from.
If you have the bootable Catalina installer the full package then
it would be easier by far to create the installation media from
the terminal command line.

Subject: Re: Problems trying to create bootable USB Drive
Hello,
Well I downloaded install disk creator and it does have a much
better interface than disk maker X. When I used it, it appeared
to have worked. However when I go into system preferences/startup
disk the flash drive is not listed. No matter what I do I cannot
get this to work. I have a new flash drive on order from amazon
that comes tomorrow. Both of the ones I have are older ones. They
are USB 2.0 and 16GB. The new one is USB 3.1 and is 32GB.
Anything else I can try while waiting on the new flash drive?
Also if I do a restart and hold option down is there a way for me
to tell if it did use the USB drive to boot?
Thanks,
Greg Wocher

Hello all,
I have been trying for the last several days to create a
bootable USB drive so I can do a clean install on my mac. I am
using a 2015 MacBook air that I bought in 2016. It is running
the latest version of Catalina. I am using a program called
Disk Maker X to create the USB drive. I have used two different
flash drives I own. After completing the process, neither flash
drives are recognized as start up disks. I am not sure what I
am doing wrong. Anyone have any advice on what I can try so I
can get a bootable USB drive?
Thanks,
