- How To Uninstall 32-bit Apps On Mac Catalina
So I have been having recurring audio problems with my Mac (OSX 10.15.4) for the last several months. I have a general idea of how it started, which is that I had been messing around with audio routing apps and Audio Midi Setup. To uninstall Office for Mac 2011 move the applications to the Trash.Once you've removed everything, empty the Trash and restart your Mac to complete the process. Before you remove Office for Mac 2011, quit all Office applications and make sure there's nothing in Trash that you want to keep. Leave Office applications closed while you go through this process. Since macOS Catalina only supports 64-bit applications, some crucial apps might become incompatible with your Mac. It has replaced iTunes with different apps (like Music) and has created an iTunes XML file crisis. Due to this, a lot of music enthusiasts and DJs are downgrading from macOS Catalina. The key to reinstall mac OS Mojave or Catalina without losing data is the backup, since no one can guarantee all data will be perfectly maintained after macOS reinstallation. However, if we unfortunately lost files after Mojave or Catlina reinstallation, Time Machine or Cisdem Data Recovery is helpful to recover them back.
What are startup items?
Startup items, or login items, are services and applications that launch every time you start your Mac. These are applications that sneak into startup items without notice, never asking if you need or want them there. This way you may end up with a dozen apps launching as soon as you turn on your Mac, weighing heavily on its processor and memory capacities and slowing it down. Such items can increase your Mac’s startup time and decrease its performance.
Plus, sometimes when you remove an application or a service, it leaves a login item with a broken link. These broken login items are completely useless, cause unwanted messages, and waste your Mac's resources (because they look for non-existent applications). Whether you're running macOS Catalina or El Capitan, or earlier — it's all the same, so just read on.
So, let's go over how to take control of login items, and how to get rid of unwanted, broken or hidden startup items.
How to disable startup programs?
Do you want to stop programs from running at startup? There’s an easy way to remove programs from startup and get your Mac to load faster on launch. The fastest way to turn off startup items on Mac is an app like CleanMyMac X.
- Download CleanMyMac for free.
- Launch the app.
- Open Optimization tab.
- Click on Login items.
- From the list of apps, disable the ones you don’t need on startup.
- Done!
How to change startup programs manually?
Disabling Mac startup programs is possible manually. Therefore, if you have some time and would like to do it yourself, follow the steps below.
Your login items are listed in settings. One of the easiest ways to control startup items is inside System Preferences > Users & Groups.
- Open System Preferences.
- Go to Users & Groups.
- Choose your nickname on the left.
- Choose Login items tab.
- Check startup programs you want to remove.
- Press the “–” sign below.
- You’re done.
- If you need to add an item back, press “+” and choose the app you’d like add.
- Then restart your Mac to see the changes.
How to fix broken startup items?
Broken Mac startup files are left there because some part of apps are left on your Mac long after you’ve moved the app to the Trash. To get rid of these parts and to fix your startup, you’re going to need CleanMyMac again. First, you need to check if they’re among startup items and disable them if so. You can do it following the instructions above. Then you need to remove app leftovers. CleanMyMac works fine on macOS High Sierra and earlier OS.
- Launch CleanMyMac.
- Choose Uninstaller tab.
- Scroll through the list of apps.
- If you spot any app that you’ve deleted, check them.
- Delete the app leftovers you’ve chosen.
You can also find and remove broken login items with the help of System Junk module:
- Choose System Junk tab.
- Click Scan.
- Review details and click Clean.
Finally, you need to clean your macOS startup items through launch services:
- Open Maintenance tab.
- Choose Rebuild Launch Services.
- Hit Run.
- Done.
Once you do it, all broken app data on your Mac will be fixed.
Remove daemons and agents from startup process
If speaking of files, first go to the system folder /Library/StartUpItems. Here you’ll find all the startup files that are being launched with the system. You can delete the login item you think is necessary if you’re totally sure what you are doing.
Also, the /Library/LaunchDaemons folder contains a bunch of preference files that define how the application that is being launched along with the system should work. You might want to delete some of these files as well if you know you don’t need them and removing them is safe.
The /Library/LaunchAgents contains preference files responsible for the apps that launch during the login process (not the startup).
The above-mentioned folders contain app-related files. However, you can also check system folders to review whether you need some of the system applications to be running on startup:
- /System/Library/LaunchDaemons - note that besides preference files this folder contains other important system items that are recommended to keep untouched.
- /System/Library/LaunchAgents - most probably, you won’t also find anything worth removing in this folder, however, keeping this location in mind might help you find files related to a problematic app that causes troubles on Mac startup. If you have a problematic application that messes about on login, you can try to trace it back from this folder.
But, if you’re looking for simple ways to remove login items, we suggest using a professional Mac utility. Download CleanMyMac X for free and make unwanted and broken login items a thing of the past.

Part 2: Preparations for Downgrading macOS Catalina
It doesn't matter what kind of situation you are in, you can easily downgrade macOS Catalina to a previous version. Although Apple does not provide a direct method to do it, there are certain loopholes that we can exploit. Before you learn how to downgrade from macOS Catalina, prepare your system by following these steps:
1. Back up your Mac
First things first – make sure that you maintain a backup of your data as you might end up losing some files in the process. Also, if you wish to downgrade macOS Catalina using a previous Time Machine backup, then it is important to keep your existing files safe.
1.1 Back up data using Time Machine How to use split screen app on mac.
Time Machine is the native application in Mac that is used to backup and restore our data. To use it, you can just attach an external hard drive with enough free space. If Time Machine won't detect it automatically, then launch it by visiting Finder > Applications. Now, select a backup disk and start the process to create a Time Machine backup of your data.

1.2 Back up data by copying and pasting
If you don't want to create a dedicated Time Machine backup, then you can simply copy and paste specific files as well. To do this, just attach any USB drive, hard drive, and any other external source. Now, go to the Finder and simply copy and paste the files you wish to save from Mac to the attached media.
2. Enable external media booting
If you wish to downgrade from macOS Catalina using a different startup disk, then you need to make this tweak on Mac settings. To do this, you can just go to Finder > Applications > Utilities and launch the Startup Security Utility application. From here, just enable the option to allow booting from external media. You need to enter the administrator account details to save these changes.
3. Erase the Mac drive
Lastly, you can just erase the Macintosh HD entirely to have a smooth process. This would get rid of the macOS Catalina components and you can easily restore files from a Time Machine backup. To do this, just go to Applications > Utilities and launch the Disk Utility tool. Select your Macintosh HD from the sidebar and click on the 'Erase' option from the toolbar. Confirm your choice and select the file system and partition table option for the formatting.
Part 3: How to Downgrade macOS Catalina to Mojave or Other versions
There are different ways to learn how to downgrade from macOS Catalina that you can try. For your convenience, I have listed three ways to downgrade from macOS Catalina that you can opt for depending on your system. We have started from the basics and have gradually moved to complex solutions.
Solution 1: Restore macOS Mojave from Catalina with Time Machine backups
If you have already maintained a Time Machine backup when your device was running macOS Mojave, then you won't face any trouble downgrading from macOS Catalina. For this, we will take the assistance of macOS Utilities and will restore the system from an existing Time Machine backup. Beforehand, just make sure that you have already saved your existing data from your Mac. To downgrade macOS Catalina from a Time Machine backup, follow these steps:
- Firstly, connect the Time Machine backup drive to your Mac and restart your system.
- Press and hold the Command + R keys when it restarts so that your system would boot in the recovery mode.
- Once your system would boot in the Recovery Mode, you will get the macOS Utilities option. From here, just click on the 'Restore from Time Machine Backup' feature.
- This will launch a dedicated wizard to perform Time Machine data recovery. Click on the 'Continue' button and select the source drive where the backup was saved.
- In the end, just select the appropriate backup file and restore it to your Mac. Apart from its data, it would also downgrade macOS Catalina to macOS Mojave.
Solution 2: Downgrade to macOS Mojave via macOS Recovery
If your Mac did not come pre-installed with macOS Catalina, then you can also try this trick. In this, we will first boot Mac into a recovery mode and will choose to reinstall macOS. This will automatically install the default version of macOS that came pre-installed on your system when you initially purchased it. For instance, if your system was running macOS Mojave initially, then it would just downgrade from macOS Catalina to macOS Mojave.
- Firstly, shut down your Mac and wait for a while. As it would turn on, press the Command + R keys to boot it in the Recovery Mode. You can also press Shift + Option + Command + R keys instead to boot Mac in Recovery mode over the internet.
- As your system would boot to the Recovery Mode, click on the 'Reinstall macOS' button under the macOS Utilities window.
- Now, you can follow a simple click-through wizard and maintain a stable internet connection as the default macOS version would be installed.
Solution 3: Downgrade macOS Catalina with a Bootable Installer
Lastly, you can do a clean installation of another macOS version by creating a bootable media. For this, you would need an installer package for a previous macOS version. You can go to the Mac's App Store for this, use any third-party web source, or download it by using someone else's Mac that is still running on an older macOS version. Once you have the installer of the desired macOS version ready, follow these steps to downgrade macOS Catalina.
- Take a USB drive or an external hard disk with a minimum of 16 GB of space in it. Now, go to Applications > Utilities and launch the Disk Utility app.
- Choose the connected external drive and click on the erase button to format it. Make sure that you pick the HFS+ or APFS format that is supported by Mac.
- Great! Once the hard disk is formatted, launch Terminal from Applications or Spotlight and run the following command:
sudo /Applications/Install macOS High Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/External --applicationpath /Applications/Install macOS High Sierra.app
- The above code works for macOS High Sierra (as you can easily avail its installer). The code would be slightly different for other macOS versions. Wait for a while as this would create the connected drive into a bootable media.
- Once the bootable media is created, you can boot your Mac in the Recovery Mode, go to Disk Utility, and erase the Macintosh HD entirely in a supported file format.
- Now, you need to take the assistance of the Startup Manager. Just restart Mac and hold the Option key as it boots.
- As the Startup Manager would launch, you can just use the arrow keys and select the connected bootable media to load.
That's it! You can now follow a simple wizard to downgrade macOS Catalina to a previous macOS version instead.
