00:00 Info
00:26 Backup User Folder
00:44 Time Machine Downgrade
01:26 Recovery Partition Downgrade
02:34 Create Bootable USB Drive with Desired macOS for Downgrade
04:23 Modify T2 Mac Security To Allow for External Disk Booting
05:10 Reboot to Bootable USB Drive
05:33 Open Disk Utility and Wipe Drive
06:10 Install MacOS
06:50 Copy Back User Files
OPTION 1: Time Machine Backup Downgrade
You Have a Time Machine Backup of the Previous macOS you want to go back to. Please Note: You must manually backup all new files you created on Big Sur to an external drive before proceeding with a Time Machine Restore.
How to Restore with Time Machine Backup with Previous MacOS:
1. Reboot into Recovery by holding Command + R on Startup
2. Choose Time Machine Backup and Select the Backup to restore from.
OPTION 2: Recovery Partition Downgrade
Boot to Recovery Partition - Options Below:
Command + R
Reinstall the latest macOS that was installed on your Mac (recommended).
Option + Command + R
Upgrade to the latest macOS that is compatible with your Mac.
Shift + Option + Command + R
Reinstall the macOS that came with your Mac, or the closest version still available.
OPTION 3: Create Bootable USB Drive with Desired macOS Downgrade
You have no Time Machine Backup. Copy User Files off to an external drive. Please Note: All Apps and Files will be wiped with this process, so make sure to backup what you can.
1. Make note of all your Apps (Take A Pic of Apps Folder) and Copy any Serial Numbers or Required Info from within the App.
2. Copy whole User Folder to External Drive. Some Apps can be copied this way as well, but I prefer to reinstall all apps.
3. Download the MacOS you want to go back to.
4. Create Bootable macOS Installer Media.
5. Reboot into Recovery by holding Command + R on Startup
* T2 Macs will require modifying the Security to allow booting to older macOS.
6. Boot to External Drive - Choose Disk Utility and Wipe the Root Drive
7. Install macOS Catalina
8. Restore User Files and ReInstall Apps

2:01 You save my life, thanks.
bro do u get stuff deleted
Which way did you use?
i realize Im kinda randomly asking but does anybody know of a good website to watch newly released series online ?
Very straight forward and most of all, less talk. Thanks for this awesome tech video.
Thanks bud! Have an awesome night!
Thanks! This really helped me out a lot today.
Very good video, comprehensive, thanks!!
Hi, thank you so much for your help. I was just wondering if the process deletes all your stuff in your Hard Drive after completing this process. Cheers.
you are my life saviour! i followed another youtuber i was stuck, thanks to your video🥳
Big Sur have a big problems on my imac 2017. Thanks for sharing. God Bless You...
I have the same mac, how?
I love tutorials like this! Straight to the point and effective! Thank you sir!
Thanks bud!
Thank you very much for this video!!
Wow you save my life, thanks brother! 😃😃😃
Thank you man, I love you so much!
Thanks bro really good and simple explanation. Big Up to you 👍🏼
Thanks bro! Have an awesome Sunday!
Thanks a lot, bro! I've found this video very helpful for me. Like!
Such a big help! I choose the first option you did, it looked slightly different. I'm using a MacBook Pro 13, not sure if that had anything to do with it but it all resulted to the same. I decided to downgrade straight back to Catalina within 30 mins of upgrading to Big Sur, which I can't stand. Now I have a problem, the "other" storage on my Mac is at 120gb which was 33gb before and after the first upgrade. Any help on how I can reduce this without wiping my entire Mac? Thanks!!
Thank you for this! It was a lot of help (:
Glad it helped Clara! Have an awesome weekend!
Very Good Tutorial broo!! Thanks a lott:))
Glad you liked it Edison!
Hi, this was really helpful. I still have the 'Update' Volume appearing on my desktop after each reboot, if I open Disk Utility I have three volumes appearing on the internal NvMe drive - OS, Data and Update. How do I get rid of the Update Volume? Thank you.
2:01 i’ve been at this since the 3rd day i had Big sur, no luck.
sorry for my silly q - when you did time machine restore option - will there be a post Big Sur back up option there or do i need to know when i upgraded. Cheers
I did everything right (3 option) but, for whatever reason, when I restart the mac the bootpicker only shows Mac HD. It doesn`t show the bootable usb. Tried numerous times. Is there an answer for this issue?
What do you do in a situation where no disk option is shown asking for where to install Catalina in method 2?
What if you have split fusion drives, I have two internal SSD and HDD hard drives. Do I erase both?
You show copying user folders on to backup drive and return, I got that part. Can you do the same with the Apps folder? After the Downgrade install can you just copy the apps folder into the new partition as well? or will it require a clean re-install of all Apps. I went back fro BigSur crap to Catalina. I do have a Previous Catalina Apps Backup, can I copy that onto the Catalina Partition Apps Folder. Great explantion by the way
which are the keys you type when you are on terminal ?
excellent video thanks, i had bootable Catalina USB but it wouldn't let me pick the Macintoch HD to install on, only after creating a second APFS Volume it did, but then i ended up with Dual-boot MBP. Cool but not sure if this the amounts to extra errors on Catalina i now notice in the system.log.
After watching your tutorial i see that it is possible to wipe the HD first. Didn't work with me but might have gone about it wrong. Need to give it a 2nd try.
The encryption is on, so not sure if T2 will allow the wipe, and also not sure what happens when encryption is turned off, as in, will data/disk be available straight after i turn it of or does all the the data need to be decrypted before anything.
Thanks for that tuto, for the third option, do i need to save all my data from my mac to an external driver or none of the data will get lost when downgrading to Catalina (from Big Sur)
Gracias hermano, me ayudo a restaurar mi Mac con la opción de los comandos (3). Give thanks,
Excellent tutorial 👍
Thanks Fons van Swaal! Hope all is well bud!
4:23 saved me, thank you
I tried option 1, but my time machine backup taken on Catalina is apparently an old format that can't be used to restore, apparently the format is now apfs for big sur....
Does the last method keep also applications and key licences ? I need to downgrade from Big Sur to Catalina but i'm afraid of losing pro tools, ableton live, photoshop licences, and parallels desktop also...
I made a backup of my current (Big Sur) home folder, not sure how to create a Time Machine Backup of the Previous macOS I want to go to (Catalina)?
Top stuff, subscribed!
Thanks bud!
I just bought 16 inches macbook pro somedays ago , it was come with catalina but I upgraded it to big sur and now I wanna go back to catalina .
Tell me a one thing can I install mojave in new macbook pro ?
This video saved my life. I hope you can help me. When I was in the screen to choose the hd I had two options, Macintosh and Macintosh HD Data, why? 🤔
Hi. What if my Mac couldn’t support the Big Sur installation so it went halfway. How do I downgrade it? Pls help, I’ve been searching for answers 😭
when installing from a boot drive, TIME MACHINE doesn't read my BIG SUR back ups. When I go back to BIG SUR, it's all there. So frustrating. Any ideas on how to work around this?
My Mac is new so I don’t need backup. What I need to do? Thank you.
What external hard drive do you recommend and how much space would you say?
Do I have to back up my whole computer to downgrade from Big Sur to Catalina. I’ve never done a back up
Did option two, after installation attempt, a prompt came up that says - An error occurred while preparing the installation. Try running this application again. I tried, and same thing happened. Any ideas?
thank you so much for this, I just got a late 2014 MacBook pro 15 inch, I happily use it on Catalina for a while, then I decided to upgrade to Big Sur because why not, did so, I hated everything about it, mostly the UI design, but I kept using it, besides for the UI it worked fine, but then I started having all sorts of problems, too many to count here, but the major ones are:
1. unexpected kernel panics
2. unexpected shutdowns
3. it getting way too hot
4. applications crashing or freezing
5. applications refusing to open
6. the entire system freezing
7. the entire system freezing and causing a kernel panic
I know for a fact it wasn't any of the software I had, as I had them before the upgrade and had them on my old 2009 MacBook (which funnily enough, is way more reliable with 10.13, an unsupported OS)
I just really hope this fixes all my problems, if not, I'll just be happy with the better looking UI.
When I download Catalina from app store its download mac os Catalina and says yous installation failed and Catalina installer not save in application folder.can you help me
I did like you said in the security part I didn't get these options it was only about adding or removing a password
I ignored this part and went along to do the diskutality to delete the container disk 1 it didn't click and tried to check with first aid it says it's locked
Does anyone know if using the Recovery Partition Downgrade method wipes everything from your Mac? I want to keep everything i just need to be back on the original operating system i had as Big Sur doesnt work for me
Is it work with MacBook air 2020?
Thank you!! 🙏 🍺

THANK YOU BRO! Everything went 100% perfect!!

Hi, my Mac is new so I don’t need backup, what I need to do?
ok so im reinstalling with the 2nd option but im not getting a drive to install it to. what do i do?
can you use catalina without having the drive connected?
6:56 I'm translating from google translate when do we need to remove the usb disk
I am unable to copy the software update (downgrade) to my external drive. This is the result I get:
sudo: /Applications/Install\ macOS\ Mojave.app/Contents/Resources/createinstallmedia: command not found
I am also unable to see it in the launch pad.
Can you help me, kindly?
Did Option 2 with trying to downgrade to the macOS version i bought my MacBook with. But every time i try to install it, it displays me, that i can't install it. Please help, macOS Big Sur 11.4 is casuing so much problems...
In options 1, it doesn’t find the backup folder, it’s basically stuck. What can be the problem?
Hi there! I was working with option #2 when Catalina/Mac had asked me which disk I liked to use but I didn’t see an option to select a disk...it’s just an empty box. Any thoughts where I might have missed a step?
Hi I don't know if you were already able to fix it but I had the same issue. Try to go to Disk Utility, click Erase, choose Mac OS Extended (Journaled) or OSX Extended (Journaled), then reinstall your OS. It worked with me.
Hi,
when authenticating as an administrator. it says no administrator found. therefore I'm stuck.
Please help!!!!!!
1:26 Thanks a lot! My mid 2020 MacBook Pro was running sluggish on Big Sur, it doesn’t run that well on Intel Macs in general.
Which option did you do ?
@@mikelaary911 Sorry for getting back to you late, I did the Recovery Partition Downgrade.
Thank you so much!!!!
Have an awesome day Tori!
Can i use that 2nd method without losing my data ?

After I downloaded mac os catalina on the appstore, it says an error occurred while installing the updates…and it won’t show install mac OS Catalina as an app😔… Please help
You are the best
I’ve tried all 3 of your methods and none of them are working for me I’ve done everything step by step each time and still nothing. Any ideas why it’s impossible to downgrade my OS on my Mac?
Hi, Is anyone have trouble with download Catalina from the app store? I tried to download it but it keeps stating that the "update not found"
I do not have an option for "select disk" when using your option 2
Does this work for Catalina to Mojave?
*URGENT*
Hi, I don't know if anyone still reads the comments on this video, but I'll try anyway.
I installed Big Sur on my 2015 15inch Mac book pro and would like to downgrade to Catalina. Unfortunately I don't have a time machine back up. The one thing I really need to save is my adobe softwares. My question is, can I do a time machine backup of one of my friends computer who has the softwares I need and do my downgrade with that ? or will I have somme Apple ID issues or something else ?
I want to download pvz but it won't let me, so the macOS version is very high and it says it's not compatible so I'm going to download it to high sierra
That's ok I found a man explaining how to delete it through terminal which is easy too
Thanks dear for the awesome tutorial
can you link the tutorial ?
@@lucascatch58 ruclips.net/video/SzlekFSLKzM/видео.html
here you go this is the tutorial
Hey Dude, many thanks for explaining how to downgrade. I went from Mojave to Big Sur, then to Monterey and everything just slowed down, and some of my external USB drives wouldn't work, so I decided to go back to Mojave which I found to be better. I read how to downgrade on Macworld but it wasn't a success. I've also watched other youtube vids, but I just couldn't get it to work. Your explanation helped me to make the switch back. But I think I have a problem.
I originally had /Container/Mac HD..... and then another Mac volume. When I reinstalled Mojave from the USB drive I was given the option to install on MacHD or Update. I chose MacHD. Everything got installed but I got a message saying - incompatible. But it all started up Ok, and it all works. However, I can't see my Mac HD anymore, only 'Update' (Drive or volume) ? I'll call it the update drive, which has a few folders and some files that I don't recognise in it. I'm thinking maybe I should have chose to install on the Update volume ? Would that have given me back the Mac HD in its own container ?
I migrated from the Microsoft Windows environment about 4 months ago, so it's all a bit strange for me. I have a 27" iMac. As you will probably know, things are done very differently here than on Windows.
Q: Should I wipe the HD again and re installed from the USB stick ? A big thanks once again, and if you have any advice for me.
hey, whenever i click "erase" nothing happens. The button doesn't respond, how is this possible? it's not greyed out or so, i just click and nothing happens. what am i doing wrong...?
I am having problems because I can't seem to get Catalina on my usb drive. I am typing in the right commands in my terminal, but it's not working. It says it is not not a valid mount point. And I transferred the Catalina installer to my flash drive. And I also created a new volume for my Catalina installation. But it keeps saying it is not a valid mount point. And I am not sure on what to enter in the terminal after the createinstallmedia --volume. Mine looks like this: --volume /Volumes/MyVolume. But I don't know on what to put where it says Volume and MyVolume. Okay so I need help here. Also, do I need to put a single dash after create install media command? And the name of my flash drive is called just Catalina. Okay, so I need help with this. Because it's not working for me. Okay so thanks a lot.
I tried the "recovery partition downgrade". However, my macbook reinstall "macos Sierra" instead of mojave. And after choose to reinstall the "macos sierra", my mac said "cannot install.. please try again". Can anyone help me solve this please? Thank you in advance.
Is it going to delete everything if I don’t backup the files
I’m trying to time machine downgrade to Catalina but I noticed that you clicked the macOS Version 11.0 isn’t that still Big Sur? I need 10.15 for Catalina. Or are you still are you still clicking macOS Version 11.0 for a downgrade to Catalina?
I don't know why apple released this update to begin with. It clearly wasn't ready. Anyway, thank you for helping us out!
I agree Sable B! Have an awesome week!
Hey maybe somebody has an answer. I can't delete my Container disk1. If i click on it, nothing happens. At 5:55. Thanks
why is it not accepting the correct password for the drive? is there something I'm missing here? the key icon appears and it just says incorrect password no matter what i type
My original software was Yosemite. I tried the recovery and my hardrive wasn't shown as an option. I hate Big Sur. I want it gone.
Thank you for the video. Well done
@Villager Gaming ikr
THHHHHHHAAAANKSSSSSSSSSSSSS !!!!! :D
I tried to restore to Sierra and it says disk locked. Now I have no idea what to do
I have a msg saying incompatible disk, pls help
the driver doesnt show on the dialog. I am supposed to select a driver, but there is none options to pick from.
Do any of these methods restore the EFI firmware? (I know the time machine restore does not...)
Hey Mike. No they do not wipe a Firmware Password if set or any EFI Settings. An Internet Recovery Wipe can remove the Recovery Partition, but not Firmware.
I used the create bootable version on external drive. I did slightly different though. 1. I copy/pasted the code from website link into terminal instead of dragging installer.
2. When trying to wipe the drive (5:49) like you by entering Macintosh HD and hit erase nothing happened. Also there was a lot of shadow gray like there was still information somewhere even though my drive has been erased multiple times trying all kinds of methods. So I just picked the Macintosh hd -data (underneath container disk 1) and that seemed to erase everything leaving 971gb of free space and it created new disk. Then exited. This time I found my hard drive as an option to install Catalina on where before there were no choices of hard disks. It was just blank underneath the Catalina installer with a slight distortion like something was there but not selectable.
Please make sure either the volume or the disk itself is mounted. Select the disk then check the mount/unmount button next to erase. Mount it if it's not, it may ask for admin password if filevault is enabled. Now you can erase.
