Hi, I have a 2018 Mini and when I created the USB installer following your tutorial it will not boot from the USB drive. If I boot into recovery and open Disk utility the drive appears but I can't do a thing with it. If I select Startup Disk the USB installer is not available/visible. If I boot back into macOS 10.15.x and select Startup Disk in system pref, the USB installer is not visible there as well. It should at least be visible within the macOS Startup Disk app, right?
Hi, I trzy to install Big Sur on my MacBook Pro with m1 but every option didn’t work. Option with Apple configurator 2 to because I wouldn’t go to DFU mode. Please help
I bought a pro m1 this morning and erased everything now struggling with installation. Lucky for me came across this video. I am going to try it now and would update u how it went. Thanks a ton in advance.
Yet another example of how fun it can be to learn something new when the person teaching you is genuinely interested and excited about it themselves. Thank you Mr. Macintosh!!!
I have been searching so many places on how to do it, there are so many places where they just explain but not in detail. Just wanna thank you for the very helpful video. Hope you make more and more videos because I think you can Rock in RUclips industry. All the best!
This is the clearest, most thorough yet concise explanatory video I've watched in a long time. I've made several bootable usb installers over the years, but this installer package with accompanying instructions is a real bonus. Thank you very much.
Your advice is worth its weight in gold. And your video is expertly produced, your narration is precise and clear, and you are amazingly well-informed and generous with your knowledge. I wish I had found this video weeks ago. BRAVO! All RUclips producers making Macintosh explainers should learn how to do it from your videos. THANK YOU.
I downloaded the official Big Sur update today and I followed your directions and they worked perfectly. I did a clean install on my MacBook Pro and everything is good. Thank you!
So, I'm frustrated. I have a 2020 MacBook Air running Monterey and a 2013 Mid-Year MacBook Pro that won't boot because of a corrupted OS. So, I'm trying to create a bootable USB to reinstall the OS. Every time I try to use the "Get" button to download Catalina on my 2020 machine, I find that it's greyed out. When I try to use the "Get" button for Big Sur on my 2020 device, I get a software update window for Monterey. Please tell me, what am I missing? BTW Mr. Macintosh, thank you for this excellent video. It's really good and very helpful. I'm just stuck because Apple "seems" to be preventing me from downloading an old OS to set up a bootable USB drive.
Great Video - Took me some time with other videos that just gave copy and past commands to do the command that did not work. Liked that you showed how to build the command from scratch. Thanks...
This worked great, I got it onto the USB but when I try to boot it up on my MacBook Pro - I see it there to install, but then it still wants me to connect to the internet to recover/install that way. I can't get past the connect to network option - and am trying to avoid needing an internet connection for this. Can I get around that??
Can i use this method and after with the OCLP INSTALLER use the "build and install open core" to the selected model to use it as an installer for unsupported Mac? If I'm doing it with the oclo, it always ends with an error massage at the process of validating installer integrity that cannot continue because the usb drive or something similar.
Tried on different macs and there is no chance to download OS from the AppStore. There is no popup with download button when clicking get button in AppStore :(

Hello mikeyevs, once you upgrade the Install macOS Big Sur app is deleted to save space. All you need to do is download it again then you can create the install USB Drive. Next time if you want you could make a copy of the installer app and move it to a different place like /Users/Shared before the upgrade.
my copying process stuck on 90%, it's been 2 days.. should i redo the command or not? i checked the activity monitor and data read on 91 GB and data written is on 78 GB.... thank you in advance.
Thank You... I was very concerned, cus I'm new to macs... M1 being the first. Your method worked perfect.. and now I can save that USB for future use if I decide to fresh restart again. ⚔🔥🖤🔥⚔
There were literally sooo many things or steps that I could have done wrong, especially as a mac noob…. But everything worked perfect. I didn’t even eat yesterday as I put all my software and plugins back on my M1. #BigSurWins
Mr. Macintosh, I need your help, I used the Big Sur package to change SSD’s. My problem is Safari doesn’t fully open and the pointer turns to a round 3 color spinning ball when it get close to anything you can click on. The only way to close the Safari App is to choose Quit in the Dock. I used the most current version of Big Sur you had had listed in your files list. Can you help me on this?
This didn't work. I followed your steps but got the following - Arguments --volume, A path to a volume that can be unmounted and erased to create the install media. --nointeraction, Erase the disk pointed to by volume without prompting for confirmation. --downloadassets, Download on-demand assets that may be required for installation. Now the mac doesn't even recognize the thumb drive when I plug it in. I think your information might be out of date.
I had an error. Arguments --volume, A path to a volume that can be unmounted and erased to create the install media. interaction, Erase the disk pointed to by volume without prompting for confirmation. --downloadassets, Download on demand assets that may be required for installation
Hello Pranam, this is the command sudo /Applications/Install\ macOS\ Big\ Sur.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume make sure that you replace /Volumes/MyVolume with your USB location by dragging the usb drive over to terminal. If you still get an error copy the entire terminal and reply here I will be able to figure out the error.
This is a great tutorial. I, however, require your help. When erasing the disk on Terminal, it gets to 10% and then the error Number (-69888, 0) pops up. I don’t know what else is there to do. I looked the error up and the solution offered was changing names and reformatting the disk, but I wasn’t successful. Hopefully you know something abt the error. Thank you in advance for sharing such an excellent video
I receive this comment in terminal when trying to create the bootable drive: "APFS disks may not be used as bootable install media. An error occurred erasing the disk." anyone know how to fix this? appreciate any help thank you.

This is extremely helpful, but - my installer is a DMG file. When I double click it, it is a package. I do not have the option to 'show package contents' and when I try to run the installer (and quit) it says I cannot install this OS. I am trying to make a boot USB for an older version of Mac OS, for a different Mac. Any ideas on how I can proceed with this?
@@Mr.Macintosh the problem is, my Mac is the latest version, I want to download an old version to put on an older 2012 MacBook Pro (which cannot run the latest OS). When I download the OS I can’t open the .pkg because I get an error stating that it can’t be installed on my Mac (I am trying to run it and then quit, so I get the install file).

I have a MBP mid 2012 retina with 16 gb ram. I have installed Big Sur 11.0.1 using the instructions of Mr Mackintosh. It works great. However whilst now the commercial version Big Sur 11 is out and I would like to install this version, But I need help. The first issue to tackle is how to download it. Further I have no idea of where to begin. Please advise and instruct. Thanks, André
Hello Andre, Big Sur 11.1 is not out yet but is coming very soon. As soon as it hits I will have a video out that will show you how to update to the next version!
@@Mr.Macintosh Hi, but I can download it on my eligible little MB Air mid 2013 Well that is what it said anyway. If I download it, does it automatically start the installation? Bc I don't want it installed on MB Air, I only want it to be saved in order to use it on the other computer. Is that possible?
If any one gets the error erasing disk error number (-69877, 0) that might mean that the USB drive is in use. Make sure that you close ALL finder windows then try the command again.
Hello, does it works for install Catalina OS ( from the app store) on a Macbook pro retina 2014 (OS Yosemite) ? I have checked the contents of the Catalina file and i have the same "createinstallmedia" like in your tutorial. Thank you.
This is great if you happen to have a computer that can download Big sir. Since i have a 2011 Mac mini and i wish to make a fresh SSD install for a 2013 Mac pro. I am unable to use this technique. I guess i add a lower IOS and then upgrade once i have the Mac pro running.
Jeff, the good news is you can download big sur from any Mac using the installassistant.pkg file > swcdn.apple.com/content/downloads/00/55/001-86606-A_9SF1TL01U7/5duug9lar1gypwunjfl96dza0upa854qgg/InstallAssistant.pkg
@@Mr.Macintosh Yeah took me some time to find the Button sequence to use when starting the computer. I was able to finally get Big Sur Installed Using the Command R keys to install the latest operation system. The whole formating the drive was more of an issue for me as I had not done it in a long time .
Sure Sophie! When you run the command you need to add sudo in front of the command. This runs the command as an administrator. You will be prompted for a password after.
My package contents>Resources has 3 files: createinstallmedia, createinstallmedia_yosemite, createinstallmedia.dylib. Using M1 Mac Air. Which file should I drag during the terminal step?
Confirmed this last night: all you need is the createinstallmedia file. I saw the same three files and chose that one. Followed the rest of the steps and it all worked. The one caveat is that once I erased the hard drive (one of the last steps) and reactivated the system, it wanted me to download Monterey instead of Big Sur. To fix this, I had to turn off my computer and restart holding the power button. Then I was able to choose Big Sur from my USB.
If you look in your applications folder after downloading Big Sur from the apply website, it will be there. I thought it didnt download either, but I checked in the application folder and it was there.
Hello. I just tried this method bur=t got the following error message: /Applications/Install macOS Big Sur.app does not appear to be a valid OS installer application. Whenever I try and download the full installer it only downloads a 14.5mb file.
Kevin, yes the install macOS big sur .app is 12-13GB in size. Try downloading it again, sometimes it will cancel out but trying again will get the entire file.
Great video! unfortunately after pressing "Y" in order to erase the volume, this messages appears "Error erasing disk error number (-69888, 0)" "An error occurred erasing the disk." any reason why? the usb is a 16gB Toshiba if it helps. Thank you!
The best part about the steps that i show is that you don't even need to format the USB drive! The create install media will erase and format the drive for you! The process will erase and partition with HFS+

Can I use this USB flash drive to install for my friend Mac Book Air 2017, which already been erased the MAC OS?
Yes you can, as long as the flash drive is USB-A.
@@Mr.Macintosh thank you

Error erasing disk error number (-69877, 0)
An error occurred erasing the disk.
Dodgy new Sandisk USB stick? Cannot reformat now? :-(
If any one gets the error erasing disk error number (-69877, 0) that might mean that the USB drive is in use. Make sure that you close ALL finder windows then try the command again.
Hello, does it works for install Catalina OS ( from the app store) on a Macbook pro retina 2014 (OS Yosemite) ? I have checked the contents of the Catalina file and i have the same "createinstallmedia" like in your tutorial. Thank you.
Trying to download installer as i am upgrading to 1TB ssd however the download keeps stopping when i get 6/7 minutes left?
I have a 2014 macbook 16gb ram 500TB ssd
Thanks for sharing, is it possible to create the installation media using linux?
This is great if you happen to have a computer that can download Big sir. Since i have a 2011 Mac mini and i wish to make a fresh SSD install for a 2013 Mac pro. I am unable to use this technique. I guess i add a lower IOS and then upgrade once i have the Mac pro running.
Jeff, the good news is you can download big sur from any Mac using the installassistant.pkg file > swcdn.apple.com/content/downloads/00/55/001-86606-A_9SF1TL01U7/5duug9lar1gypwunjfl96dza0upa854qgg/InstallAssistant.pkg
@@Mr.Macintosh Yeah took me some time to find the Button sequence to use when starting the computer. I was able to finally get Big Sur Installed Using the Command R keys to install the latest operation system. The whole formating the drive was more of an issue for me as I had not done it in a long time .
Sir my usb disk can't Bootable because the EFI partition can't create... How to solve... Thanks
Super! thank you!
Hello I get This tool must be run as root using terminal method. can you please help me?
Sure Sophie! When you run the command you need to add sudo in front of the command. This runs the command as an administrator. You will be prompted for a password after.
I'm not sure what I've done wrong, followed instructions to the T. Got to password, then nothing. Doesn't format external drive and copy.
hi there , please make a tutorial video about , how to make big sur iso file bootable usb on windows 10 please .thnx
How can you "Create a bootable macOS Big Sur USB install drive" on Windows 10 or 7 ???
Can it fix my serial number when boot it? Because my serial number is unavailable
Did you have your logic board replaced? if so they should have set the serial number!
My package contents>Resources has 3 files: createinstallmedia, createinstallmedia_yosemite, createinstallmedia.dylib. Using M1 Mac Air. Which file should I drag during the terminal step?
140kb, 122kb and 290kb respectively.
@@adamraymond4213 Did you figure out which one to download? I'm on the same step and see the same 3 files
Confirmed this last night: all you need is the createinstallmedia file. I saw the same three files and chose that one. Followed the rest of the steps and it all worked. The one caveat is that once I erased the hard drive (one of the last steps) and reactivated the system, it wanted me to download Monterey instead of Big Sur. To fix this, I had to turn off my computer and restart holding the power button. Then I was able to choose Big Sur from my USB.
We can create a BigSur USB installer from an intel computer and use it on a M1 silicon, correct ?
Amazing video!!! Excellent Job - Thank you!
Is it OK if the external drive contains other stuff then the big surr?
i canr download bigsur cause im already on monterey how do i fix that
If you look in your applications folder after downloading Big Sur from the apply website, it will be there. I thought it didnt download either, but I checked in the application folder and it was there.
The best video tutorial..
Really great video but this is what I am getting and do not understand where I am going wrong. "create install media: command not found"
.
Hi David! create install media needs to be all one word like this - createinstallmedia
@@Mr.Macintosh thank you!
Thank You , Bro . . . . you saved my Life lol
Hello. I just tried this method bur=t got the following error message: /Applications/Install macOS Big Sur.app does not appear to be a valid OS installer application. Whenever I try and download the full installer it only downloads a 14.5mb file.
Kevin, yes the install macOS big sur .app is 12-13GB in size. Try downloading it again, sometimes it will cancel out but trying again will get the entire file.
Hi everything worked perfectly but when I try install it says “This volume is not formatted as AFPS”
Reformat the USB drive as macOS Extended Journaled
Is it possible to use this installer for windows ? Like instal Mac OS on windows ?
Great video! unfortunately after pressing "Y" in order to erase the volume, this messages appears "Error erasing disk error number (-69888, 0)"
"An error occurred erasing the disk." any reason why? the usb is a 16gB Toshiba if it helps. Thank you!
Hello Andrea, sometimes spotlight gets caught in the erase. Pull the drive and quickly try again see if that works.
When formatting internal drive for clean installation, do I choose APFS file format when my bootable usb is MacOS Extended journaled?
The best part about the steps that i show is that you don't even need to format the USB drive! The create install media will erase and format the drive for you! The process will erase and partition with HFS+
@@Mr.Macintosh thanks ;)
