Downgrade From 11 To 10
Oreo Huppe
Firstly, when downgrading from 10.1 to 9.0, you are hitting 2 PAN-OS releases which are end of life and end of support. Those versions are 10.0 and 9.0. If something goes wrong when you reach either of those versions, it may be difficult for Support to help you, and you may simply be asked to factory reset and upgrade back to a supported release.
2) Usually when downgrading, you should select a config which was saved on the version you are downgrading to. It's unlikely your config can be used for the downgrades. If you don't or can't do this, you will very likely see autocommit failures and have to manually delete some things from the config on most downgrades.
I do not like Big Sur. I just downloaded it last night thinking it was going to be better but it doesn't satisfy me. I liked Catalina a whole lot better and so I tried to find out how to downgrade to Catalina but there are too many ways and it's hard to understand! I just want to switch back to Catalina! What's so bad about downgrading to a previous version of Mac OS, the whole point of me buying an Apple product is to be satisfied with what I use. I tried to do it myself, but I couldn't find Catalina in the App Store like I needed to. I don't understand why there isn't a simple way to downgrade and I think there should definitely be a feature that allows users to downgrade.
Can you stop the sales pitch and answer the question? Many of us feel that Big Sur is not suitable for our needs and we'd like to move back to an OS that works for us. I've upgraded to Big Sur and now I can't open any Microsoft Office docs without buying another subscription - why????
Ha! I doubt you'll be able to and of course, eventually you'll have to. But I wish too I coudl get rid of this. It makes my Mac look like a PC. The UI is horrible with less contrast between sections and thinner/tinier type everywhere. Jonny Ives is still getting his way apparently, making the Mac (and iOS) a crappier experience with every update.
Apple is moving to a world game-changer of computer integration by unifying iPhone Processing with apple computers universally using Apple's new processing chips, all controlled by Apple's latest operating system, macOS Big Sur.
You can download Mac OS Catalina by following the below link... it will take you to the Apple Online App Store. However, you will not be able to downgrade on a Macintosh HD that already has a newer version, such as Big Sur. You will have to erase the Macintosh HD. If you use the Cloud for everything, your Messages, Photos, Mail, Desktop items, Documents will all download to your Mac once the Mac OS downgrade installation is complete. If you store any of your Music, Movies or TV Shows on your Mac, you will need to back them up on an external drive.
Backward migration has never been an easy task, whether it's from Big Sur to Catalina or Catalina to Mohave or any backward migration; once updated to the latest operating system, you can't go back and if you do everything you did while on the latest operating system must be reinstalled manually, (individually folder-by-folder) or it will be lost.
One method is a complete factory reset and installs the original operating system that came with your computer at purchase (instructions, -us/HT204904), which you then move up to Catalina and reinstall via apple migration using the last Time Machine backup you did before installing Big Bur.
The second method is to download Catalina and on a separate flash drive or backup disk, create a bootable installer, then erase your hard drive either with Disk utility or starting up from macOS Recovery (instructions, -us/HT204904).
The problem is not Apples macOS Big Sur, the problem is Microsoft has not yet updated its software to work with Apple Silicon M1 Chip, and are asking Microsoft Word users to use Rosetta 2 until this is fixed.
On November 10, 2020, Apple announced the availability of new Mac devices based on a custom architecture known as Apple Silicon. This article outlines the support of Microsoft 365 and Office 2019 on Apple Silicon devices.
The December 2020 release (build 16.44) provides native support for both Apple Silicon and Intel-based Macs. Word, Excel, PowerPoint, Outlook, and OneNote are supplied as a Universal macOS binary, where the Mac operating system will dynamically load the most optimal app components for your device. This release of Office includes the latest optimizations for macOS Big Sur, which is the first operating system to support Apple Silicon.
No. The Office installation and update packages contain the optimized code for both Apple Silicon and Intel-based devices. This is true regardless of whether you obtain Office from the Mac App Store, or office.com - which uses the Microsoft Content Delivery Network (CDN).
For the best experience, we recommend that you let the operating system decide how it should load the Office apps. There are a small number of scenarios where you may need to tell macOS to prefer using Rosetta 2:
For instructions on how to use Office apps with Rosetta 2, see Use Office for Mac with Rosetta and Apple silicon. In the case of a third-party plug-in, contact your vendor to see if they have an update available.
This reads like an excuse. Apple used to be the computer that was easiest to use. Reading all of these complaints -- looking for one that is my problem -- is so discouraging. Get it together, Apple. Don't give us excuses. Fix the problems. This is supposed to be the company making insanely great products, not insanely frustrating ones.
I don't like Big Sur either, but I don't care to go through the mess of reverting back to Catalina. It's mostly stable enough for me to use it, and my concerns are more with the design changes that don't seem to make my eyes happy. I have managed to tweak the UI through Accessibility options like reducing transparency which does help. But all this White on gray stuff isn't my ideal of progress.
Well, I spent the last four days trying to downgrade to Catalina and I had very big troubles. I have a baseline, 2018 iMac Pro and the backup of everything. The troubles came after the restore from backup. I restored my user data and applications. All was ok, but only after the first restart: the progress bar, around 75% stopped and the computer was turning off instantly. There was no way to fix it, no NVram zapping, no SMC reset, no Safe Mode booting was working at all. I had to repeat this many times to get it working, after restoring only my home folder and installing back all my apps one by one. Now finally I can use it, though is a long job to have all my apps installed. One thing remains of Big Sur, the startup chime.
I agree with what somebody wrote here. Applies making it very difficult if not impossible to smoothly go back to Catalina once you have installed Big Sur. From what I can tell with my Focusrite audio gear, there are security features in Big Sur that will stay on your computer. I have spent the better part of this week with Time Machine and Migration Assistant and havent gotten anything to work smoothly yet.
I tried this and it worked. There may be a better way but I put this process together myself. You need a bootable disk with an older version. Because higher level OS will not allow you to just run an older MacOS installer.
1) Make a copy of all your important information on an external drive. It is best to use normal drag and drop and not some fancy program. Because drag and drop is going to work while specialized backups are complicated and are not guaranteed to work. I used a decent Samsun external ssd an formatted it using "disk uitily" exactly the same as my mac is. In my case "APFS". DIskutiity is standard on Mac and you will find it from "LaunchPad". Remember it launchpad on Big Sur has a different looking icon but works the same. Please use a good high quality drive it is your data! Then after you copy everything you want go to Finder or DiskUtility and eject it. Disconnect it and keep it some place safe. This will be useful as a last stand backup. Apple Cloud is great and I use it but never hurts to have a simple physical backup in your house.
2) Now you need to make a bootable Mac drive with the version you want downgrade to. You need another external drive. I used another SamSung USB 256 gig SSD. But a smaller pin drive probably works. Then you need to install and older version of MacOS on it. The version you want to downgrade to. You can download it but can be a pain to find. It is much better if you keep around the MacOS installers from older versions on the backup disk for times like this. Once you have a say MacOS Catalina or Mojave installer you need to install it on the external driver [IMPORTANT: Do not use the backup drive! Use another one]. As I said you need a Mac running that or an older version of MacOS. I have 3 Macs and I used one running Catalina to run the installer. Before using the installer you need to format the external drive to a GUID partition using the DiskUtility. NO need to partition or add volumes. Now when you run the MacOS Catalina [on a machine running Catalina or older] you get to pick a disk to install on. Make sure you use the external OS disk you just formatted. It will be a while and now you got a bootable Catalina external USB drive. Be sure to put a copy of the MacOS Catalina installer. Now plug it into your Mac which you want to downgrade and then boot it. Remember you need to switch the boot disk from Startup Disk which is in System Preferences on the machine you want to downgrade.
B) You Mac may not allow booting an external drive. This requires you go to Security Utility and allow it. This utility is only available in the boot/rescue screen not while Mac is booted. You need admin privilege but you can go in and allow booting.
Run the MacOS Catalina installer while booted from the external disk and install a brand new Catalina on your Mac. Your Mac is now downgraded! Beware you must configure it and either shut off the internet or as soon as you get in go into Updates from System Preferences and shut automatic updates or it will update you right back to Big Sur.
