This might be a dumb question...can i run the public beta of Mohave from a USB thumbdrive only (and not install it on my computer at all?) Yes, I checked my friend Google, but couldn't find a definitive answer...

Question:
"Can you run Mohave only from a USB drive?"
Yes.
You can run it from a firewire drive, too.
You can run it from a platter-based external hard drive, or an SSD.
You can even run it in HFS+ if you want (I put up a thread on that in this forum).
The Mac will boot by default to whichever OS is selected in System Preferences > Startup Disk. So go there and make sure the internal drive is selected following the Mojave install.I came here to ask a similar question. I have a new external platter-based hard drive.
A few questions …
I'm guessing that you get asked which drive you want to install Mohave onto …
Does the Mac ask on start up which OS to boot ?
What happens if you want to boot the Mac without the hard drive attached ?
If you don't want to keep Mohave, can you get the Mac to basically forget about Mohave and always boot from the internal SSD ?

Yes. Just hold the Option key during boot. The boot-picker screen will appear, where it shows partitions that may be bootable. Just click on the one you choose
What happens if you want to boot the Mac without the hard drive attached ?
Your Mac will look for another boot system. Assuming you have a bootable system installed on the internal drive, it will usually try that one first.
If you don't want to keep Mohave, can you get the Mac to basically forget about Mohave and always boot from the internal SSD ?
If you want to boot to a particular partition, select that partition in your System Preferences. It will then use that as the default, and may take somewhat less time for booting when the hardware doesn't search for other bootable partitions first. So, you can leave the Mojave system attached, but if you don't make a choice, the drive selected in Startup Disk will normally be the default. If you don't have ANY drive selected, then your Mac may still default to the the internal drive --- but not always, and the boot time could be longer than necessary. It's a Good Thing™ to select whatever system you want as the default in Startup Disk. It may keep you from wondering why it randomly booted to something else that you had connected, and may save you some time with a somewhat quicker boot.

To boot from Mojave without setting it as the default, start your Mac and hold down Option until the boot menu appears.
I just reinstalled Mojave on an external USB SSD, which is number 3 or 4 of external USBs that I have installed
Thank you for help DeltaMac! I did what you said, but now when I try to install it on my USB, it says ‘This disk is locked.’ However, i can’t find a way to unlock it. Permissions are set for ‘read & white.’

Yes, the USB storage device/flash drive -- whatever you have for a bootable installer.When you say ‘Reboot to your installer’ you mean the USB drive right?
