Out of the Box - New 16" NOT Clean Install of Catalina?

The USB install will be faster to complete the initial "copy the installer files to the new system", as the files don't have to download first. Yes, the net result will be the same.

Thanks, decided to give the internet recovery method a try this time using this tutorial:

https://wccftech.com/how-to/how-to-...without-usb-using-internet-recovery-tutorial/

I noticed a couple tutorials didn't mention actually erasing the SSD, while this one does. Not sure if the result would be the same, but figured this is more so what I'm looking to do, so I'll follow this tutorial and report back how it goes once complete.

Out of the box I have 473 GB free (512 SSD, obviously), I'll see what it becomes after this, without the junk.

T2 equiped Macs won't let you install Catalina from an USB. Not anymore.

that’s not true, but you do need to have already had an administrator set up on the computer, and you do need to have internet access, as well as enabling the option to boot from an external drive.
Regardless, internet recovery is definitely the better option.

Didn't know that.

Do you think Apple could track spoofing the T2 chip somehow?
 
Finished the clean install using internet recovery and now back up and running, gained back 10 gigs of space. Now have 483 free to start with instead of 473 like it was out of the box.

Made sure the T2 security boot settings were still off when I was done just in case I have a problem in the future, and they were - this setting is independent of a clean install.

Thanks guys.

I received my 16" today...why would the fact the 16" runs a forked OS for right now negate the benefits of doing the clean install now? Looking at your old post about it, you said you still were able to get rid of the junk like Garageband, so why wait until 10.15.2?

I don't plan on doing a clean install at every 10.15.X update, so I guess I don't see the difference in doing a clean install today from USB on 10.15.1 to get rid of the junk and then doing the normal update path to 10.15.2 and beyond once available, vs. waiting until 10.15.2 to do the clean install and then following the same normal update path to 10.15.3 and beyond.

I just think the steps I took were limited in benefit given that 10.15.2 will be the version you would want to create a boot flash drive with and clean install from. The ultimate goal is to avoid having the unwanted extras installed in the process, and not have too many steps to accomplish that. That's why I recommend doing this once 10.15.2 is released.

There have been machine specific builds for macOS since the very beginning.

In general yes, but you couldn’t run the G5 variant 10.2.8 on an iBook G3. If you are referring system specifications set by Apple for model machines OS X can run that’s a different. For instance, Apple stopped officially supporting 10.2 and 10.3 on beige Macs, but you could use Xpostfacto to get it to work.

I recently watched a YouTube video where someone did a live marathon to get Catalina to install on a 2009 Mac Mini even though it was not an officially supported machine.
