Downgrading from MacOS Big Sur to Catalina the Easy Way
HTML-код
- Опубликовано: 31 июл 2020
- DISCLAIMER: The previous method with the beta would allow a backup if it was a time machine backup, but now you can’t get any data back unless you have an iCloud backup with all your files.
DISCLAIMER: If you lose any data from this it is not on me. Do this at your own risk!
In this video, I am teaching you how to downgrade from MacOS Big Sur to MacOS Catalina the easy way.
The latest beta in all honesty is glitchy and due to that it may be affecting your day to day usage of your Mac.
Details before installation:
1) Make sure that your USB/External Hard drive is a minimum of 12GB.
2) If you would like to keep your data, backup your storage via Time Machine or another SSD.
Path for Terminal:
sudo /Applications/Install\ macOS\ Catalina.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume
Things to keep in mind:
1) Make sure to connect to your Wi-Fi after booting into the start up disk menu.
2) The download times can vary based on your internet speed.
3) Apple recommends you do the downgrade method this way, here is the link if you need more information: support.apple.com/en-us/HT201372
I am back to posting a video weekly, they cover a variety of technology related subjects such as How to/Help, Unboxing/Review or rumors about upcoming products such as the iPhone 12.

Hey guys, since Apple released the official version of MacOS Big Sur, the App Store will not show MacOS Catalina, you will need this direct link: apps.apple.com/in/app/macos-catalina/id1466841314?mt=12
This will take you straight to the App Stores MacOS Catalina Installer. Hope this helped and thank you for the support!
thankyou
still not working! it doesnt download the page it redirects you to the new mac version big shit sur
Hello! I tried this method and my disk says “you may not install to this volume because the disk has a password” and i know the password to unlock it and there’s no other option.
I just downloaded it using: apps.apple.com/us/app/macos-catalina/id1466841314
I can’t switch my hard drive to Mac OS journaled it just shows the APFS options. Please help!
Thank you so much...I was reading through several articles and was totally confused...This made it !
Thank you! Spent hrs earlier using tutorials online that skipped out a vital part of wiping the current HD... you solved this! 🙏🏼
What happens when you wipe the current HD? Does this get rid of everything you have in it like Logic Pro or applications you’ve paid for/downloaded
@@skinnydisastersvevo I’m wondering the same thing. Any luck?
@@Turtleguy510 nah g. I ain’t figure dat shit out yet. Kmt
Thank you so much for your help, Ashkap30! I have a mid-2015 Macbook Pro, & I made the mistake of upgrading to Big Sur. Immediately, everything was waaaaay slower & my battery started to drain like crazy. I was feeling annoyed and discouraged, then I found your video. I followed it step by step & everything worked great, as I was able to successfully downgrade to Catalina.
I do have an important warning to mention, though. You see, I created my Time Machine backup on my external drive with the Big Sur OS. Then, when I was back to Catalina, I could not migrate the backup because my Mac could no longer recognize the Big Sur OS that I had used to backup my Time Machine. Fortunately; though, I just so happened to backup my files on icloud, just in case. That was a God-send because all of my files for work were there.
Thank you for this video! I installed Big Sur and instantly had my fan running at all times even when I have absolutely nothing open. Called Apple support, went to the Apple store... they told me someone would call me to help downgrade to Catalina but didn’t get a call.. so this really helped and saved me so much time! Thanks!
Did you have to reinstall all your applications? Just upgraded and lots of my software doesn't work! I'm freaking out, I want to be able to roll back!
I have watched about 5 other videos and this was the only one that actually helped me succeed in this process. Thanks a million I appreciate it.
Glad it helped!
After hours searching for solutions I am happy to finally have found this video. Worked perfectly! Thank you!
Thank you so much. You should consider teaching because this snappy step by step and clear method is so rarely found in teaching! You saved my research project because I can't run the app on Big Sur.
Hello mate, just wanted to thank you for this video. Really helped me out. Wishing you all the best!
Thank you so much for sharing this!! After trying some other videos for hours, this is the one that only worked for me! 😊
Hi, can I know after downgrading, all files and settings are still there or all files are gone and settings are reset?
Thank you so much man, this saved me so much time and concern!
Thank you SO much! This helped! Very informative and easy🙏🏽
Thanks a million. It made my day. Carry on the good work. ✌️
Thanks for watching and supporting this channel
This is the most clear tutorial on RUclips. Especially to someone who isn’t too computer savvy.
There were extra steps I had to take to get around security (took some searching on the support link in your description) but other than that everything else worked as explained. Thanks to you I can get the ONE not working app I need for class to work again!
@@lostboirufio me too. Ever figure it out?
Great video Mate!! You deserve more Subscribers.
Bruh.. u r the man THANK YOU Merry Christmas from NY
Thank you so much! It worked for me. Video was super helpful!

YOU HELPED ME A LOT! Thank you!!
Thanks so much for ur video I could help a friend thanks to this. So far the best video and most explanative of all I found.
Thanks very much 🥰 my Mac actually runs on Catalina thank you again !! Very clear solution
I don't normally leave many comments, but I have to say this video was by far the best to explain easily how to downgrade my Mac.
Bought a usb pen drive and a usb type c cable both for like £12, and with to this video I will no longer be frustrated with the problems I was having from BigSur.
Thanks for making this video, was very helpful!!!
Thanks for watching and supporting the channel!
Worked like a charm, ty so much!!
Worked! Thanks a lot for the great tutorial!
You deserve my respect man! Successful
Thank you very much! You really help me 🙏🏾 Best wishes for u! Greetings from Brazil 🇧🇷
Thank you! Your video was incredibly helpful!
Bro you saved my life, I was stacked on disk utility and the disk you erased was the one I was looking for to erase, but I didn’t know…. Thanks alot 🙏
you just save my life, I update big sur for 2 week ago, and many thing not suppot for my work. thanks a lot.
Got it! Thanks so much bro!
You should keep doing such valuable things
Thank you!!! Second all the comments here. This is best and easiest tutorial by far. You explained everything really well. Was able to downgrade without a hitch. Big Sur has been a punishment. Overheated my Mac and drained my battery. Apple support was ZERO help.
Many thanks I also unchecked the auto update and auto install check boxes in settings so apple don't auto update me to big sur again at least not till all bugs sorted , thanks again you are a star
Thank you for this!!! New subscriber.
Thanks for the good vid, really helpful. Before I do this can I check that all software downloads and my music projects will not be erased? Thanks again
Does this downgrade work on MacBook air M1 2020?? I really need to make it catalina, can u help me!
you're awesome man thanks a lot
Hi, i’m terminal when I press y, it says “Error erasing disk error number (-69888, 0) An error occurred erasing the disk.” How to I fix this?
i did just not and it worked perfectly ! thanks again brotha
Did you do it with the latest Mac ? (M1) ?
Thanks for the tutorial my guy
how long did it take for your installation to copy to the disk? it's been on 0% for over 30 minutes, is this normal?
@AshKap30 you're a life saver, thanks a mil for taking the time to make this video.⭐⭐⭐⭐⭐
Windows 10 is working better on my mac than Big Sur. MacOS Big Sur is a complete mess
Bruh that’s legit facts
yeah, my mac is a bit slower than on catalina and continuously got 80 C and the battery lasts for 6h instead of 10h
Give it some time... Apple isn't perfect, although they come close.
The same here
Yeah, I saw that . I was trying to put my sister Mac desktop to windows 10 but just kept failing and all I was like WHATS THE PROBLEMS??? Then I realize it was the version because I had no problems and looked some videos and looked through the comments that only Catalina worked.
You. Are. A. Genius. THANK YOU!
When clicking erase and changing the format to APFS, it doesn’t work after I click erase.
Dude you Rock! I had to go back to Catalina because my Dj serato hardware wasn’t compatible with Big Sur and I upgrade before I knew that. Thanks a lot
Same!!
Same!!!
Same!!!!
Sameee
same
The disk you erased said “Update” but the disk you installed on said Macintosh HD. I could only erase the Update. But on the install screen I see both options. Which one is it?
Hey, Im following this step guide, and my Mac mini M1 is unable to / Incompatible to download Catalina from the App Store.
What can I do?
Hi, could you please help me? where can I find my volume's name? I tried Macintosh HD it was no working.
The best guide!!!!!
Can I download Mac OS from the apple website and copy it to my mac because I couldn't download it from the apple store? Does it work?
When I get tot he terminal step it says unable to erase disk if my external hard drive is empty already do we need to do that step?
it worked thank you so much my mennnn
I just found you and thank God I did. Apple support was not very helpful although I must say that all the Customer Service reps were polite. No one had the time at Apple to walk me through it. You did though and now I have my computer back. Thank you so much.
I can't find macOS Catalina on App Store :(
Can you help me. I have Big Sur running on iMac with 577 available space of 1TB, yet whenever i try to install a programming/ open it say I don’t have enough free disc space to proceed. I’m lost I’ve tried everything I can think of, yet i cant find what space they are saying I don’t have.
Hi. First of all thank you so much for your video! I wanted to ask: If I open my disk utility there are no external hard drives. It only shows internal hard drives. Do I follow the same routine and erase one of them?
Have trouble creating the bootable hard drive. My options on disk utility I only have APFS options for format type. I believe this maybe a reason why on terminal it comes up saying error occurred erasing the disk?
Hello I got Problems with my photo's after I reinstalled Catalina I can't open them is there something i can do?
My mac says that the photo bib is from a newer version, and it says I need to adjust my photo's so I can open them in Catalina Photo's
Thanks so much , I have the 2015 MacBook Pro ( 13 inch) and ever since I switched to Big Sur it’s been killing my battery way to fast . I did the SMC AND pram reset , still the same issues .
Can Catalina be downloaded on the same external drive as my time machine back up?
Thank u so much it worked for me perfectly ,,
Is it necessary to erase the bigsur volumn or can be installed without erasing os from macbook to avoid loss of data.
Do I have to errate the Volume before installing the old Mac OS or is this just for the case you want you Mac been completely empty with no old data?
I was your 100th subscriber!
Ayyy thank you for the support fam! Stay tuned for more videos this week!
In Terminal following your description I get an error message (an error occurred erasing the disc- error no ( -69888, 0)- not sure what to do next...
Please help

Brother i doing the same for my friend macbook air 2015 its got stuck after finishing copying file for making bootable at 0% what should i do bro and i would love to watching the unboxing videos
Hi, so was in big sur and did a Time Machine back up to an external hard drive. Im now on Catalina and it won't find the backup. What should I do because I don't have any of my files
Hello Ash, I am trying this but the Mac HD is grayed out, unless I boot in recovery mode. I don’t know how to proceed in recovery mode after I erase. Any suggestions is appreciated!
So, I’ve completed the transition successfully but now I’d like to restore what I backed up on an external hard drive prior to transition, do I have to worry about Big Sur coming back when I restore? Probably a dumb question but, thx in advance
Hey im having a problem, I am currently on the part where you install Catalina onto Macintosh HD, and the problem is that I don’t have enough space on my disk and I don’t know how to free up some space on my disk
Thanks, it worked, but I can’t restore data from backup I did earlier with time machine. When I enter safe mode it says there is no backup on my pendrive. When I go into migration assistant, it doesn’t find nothing. Back in Big Sur, when I entered this pendrive, it was a time machine backup file, now it’s just an empty folder, but still weighs 55GB. Please help. :(
can i use my external hard drive containing other files/i have to delete all the files in the HD first?
Hello, i did everything you told at your video but everytime when i press the power button and then ‚option‘ there is no macOS Catalina… what can I do?
Thank you bro stay safe
I got a failure on copying to disk process. The terminal writtten IA app name cookie write failed. How do I overcome this?
what if the usb drive is only 4 gigs and is there a way to do it without usb
Hi! i tried it but when my mac starts with Catalina the mouse doesnt work so I can not enter to disk utility. Any idea?
i can't download catalina. when it's completed downloading it shows there is an error. Is there a other way to get Catalina? for example from terminal?
bless up...took me 3hours..to get it done.
My macbook is two weeks old and I don't have data or something important on it. Can I skip backup and just format SSD and install catalina?
Hey question. Can I use that same usb on multiple macs? I have 2 macs that I’d like to down grade.
Hey brother thanks for your guidance. Can you give me idea that my Mac 2017 doesn't show WiFi however it's on, after upgrading Mac OS BigSur 11.5.1
Hey! I'm having a problem with terminal, its saying i need to run zsh and when i try to ignore it, i'm not able to edit anything in terminal when i copy and paste the info you gave in the description :(
Any advice for the "Volume contains an OS X installation which may be damaged" error message
I did all your instructions - step-by-step. But when it was time to choose the option at the end where after closing disk utility, I’ll have to click the 2nd option (install macOS catalina) it wasnt like that, it was still showing big sur.
I turned my macbook off and turned it back on and now I’m stuck at the startup and macbook wont open anymore 😭 I’m just stuck with the error of a globe spinning logo.
/u/AshKap30 I am twitching to Mac BigSur 14; but I need to print something out today.
so what’s the actual command to copy a .dmg to a usb, if you’ve forgotten it as I formatted correctly. Also if it is the nearest USb port cushlyyou write about about that too?
Thank you so much bro
Hi mate, I followed your steps to erase the disk, unfortunately doesn't allow me to complete the action. Its say ERROR ERASING DISK ERROR NUMBER (-698888, 0) did happen you? thank you in advance
I got my 2020 27 inch imac today and it came with bigsur (originally installed with bigsur) can I downgrade to catalina in same way? I heard that it is impossible to downgrade it cause it has been shipped with catalina. Glad if you can help
Thank you SO much! One click to ruin your computer putting Monterey on it, but with your help, I got Catalina back. 🙏 Thanks,
I have to do this to my IMac ,,, Will i be able to use mouse and keyboard ( wireless ) When i reeboot ? Thanks 😀
I guess only option for downgrade is fresh install? Is there an option to keep the data and downgrade the OS?
my erase tab icon in the DISK UTILITY is not highlighted what should i do??? i need help :(
thank you
after i downgrade can i upgrade t specific version of mac os again?
I have Big Sur and I want to go back to Catalina which my Mac had when I bought it . I don't want to back up any data . Pressing shift+option+command+R can I do it with internet recovery ? But when it says choose a hard drive for Mac OS Catalina it shows nothing and I can't choose anything . Do have to erase first ?
Select disk utility and erase 'update' disk and try reinstall os option again.. You'll get update disk to install the OS
Hey I it is showing me that command not found when I type it in the terminal and it's the exact same code I copied it from the description and even changed it to Untitled pls help
How do you do this when Apple only put thunderbolt connections ?
It said “ Untitled is not a valid volume mount point “ when I am in the terminal part . Need helps thank you !
everything went well except when I pressed Y to erase, its says an error occurred erasing the disk. what should I do?
