I always keep a partitioned thumb drive with bootable versions of all the various OS systems that my extended family uses, because invariably at Christmas I end up having to solve all of their issues they’ve accumulated over the past year, and I find that having a clean boot helps immensely.

A MILLION THANKS This worked like a charm! You didn't leave ANY steps out, told me exactly what I would see and this tutorial followed what I did every step of the way. I cannot thank you enough for this exact training. YES!!!! I have subscribed!

Yes, a bootable backup is an essential tool to have for any Apple OS owner. I find it super handy and quick to have access to it when needed. Yes, it is much more convenient to download it when needed but it's an 8GB OS and being outside the United States or in a remote area where the internet is limited when it comes to speed, it can make it impossible to get the 8GB OS downloaded. So, thank you for sharing this updated video because I'm always here watching it step-by-step while creating the USB bootable drive (even though I now after 4 updates, I've become super familiar with the process) but I feel safer going through the video just in case I forget to do one of the required step or misspell sudo lol

Great video. Built my USB drive while watching this for the second time. (paused here and there to catch up or wait for the full transfer) Now to swap out the memory and drive on the MacBook.

Thank you for this tutorial. I sat infront of my laptop for 4 hours yesterday and nothing worked. Followed this step by step n it took me 10 minutes. Im literally in tears 😩😩😩

[cbw]

I bow to you! I have been unsuccessful until following your specific instructions... Subscribed! Thank you!

[RKHAMB]

Excellent instruction video. I wasted so long going through many websites and forums trying to assist with this; your video did it! I managed to bring mac back to life. Thanks once again.

[stickyk]

Absolutely excellent tutorial. I really like how you took your time and explained everything well, leaving little room for those who watch it to run into any errors, bravo! Gets a like from me.

[aminderdhillon]

This worked!!! I had the “?” File showing up every time. I just plugged in my usb to my friends computer. Followed these instructions until it was on my USB. plugged it into my computer and held opt. Booted up from this drive and copied it onto my hard drive. And it’s working so far!! Downloading right now. Thank you so much dude! I thought my Mac was done for.

[bobsblackwell]

You have a really lovely way about you, Jeff. I've watched so many different tutorials to do this - along with trying to understand the Apple instructions... Yet you have made it so much clearer for me. I've successfully created a Catalina bootable USB. Thank you :D x

[LofiMiso]

I'm new to MacOs and this YT page has been invaluable to me. Thanks for always having the answer to all of my questions!

[afdays]

How do you revert the bootable usb to normal afterwards?
To be able to use the usb again for regular storage on mac and windows. Thank you!

[EyemotionView]

WOW!!! you guys are always the TOP LEVEL Instructors. followed every single step and I've just restored a machine that was about to be trashed. thanks so much.

[gabrielegelfofx]

can't wait to watch your Mac Pro 2019 review. I hope you're the first to get a sample because your reviews are the best on Youtube. Apple has to thank you.

[edscott]

excellent video - Jeff...outstanding guide! Making install drive as I type!

[edgarzamudio]

When are you making the video for booting of a external HD for Mac Pro (2019)

[crouch]

Hi, do I need to have the USB drive formatted before I do this? As I bought a brand new drive and want to make this boot drive straight out the packet? Or does this process format the drive when it makes the boot drive?

[tiadozeman]

Help! I have a mid 2012 MacBook Pro and am trying to update to an SSD. I already updated my RAM. I am having difficulty because the .dmg is no where in the Applications folder. I have used the search function and it does not appear, but when I check the “About This Mac” it shows I have the current version of Catalina???

[eurodancedjsworld]

by far the best tutorial I have seen regarding this topic! clean and precise! straight to the point! cheers

[Mangold]

Confusing the last part... so if I make this rebooting i can start from usb key?
