### How to Uninstall Office 2011 on Mac

### How to Uninstall Office 365, 2019, and 2016 on Mac

:a[7 Best Mac Cleaning and Optimization Software in 2021]{href='https://www.drbuho.com/how-to/best-mac-cleaner-software'}

:::

## What is CleanMyMac? 

When it comes to Mac cleaning, CleanMyMac is probably the first tool that comes to your mind. It is one of the best Mac cleaning and optimization software, and it has more than 15 million downloads worldwide. To be honest, CleanMyMac does a pretty good job both in terms of features and design.

However, one of its most significant drawbacks is its high price. You can subscribe on an annual basis or a one-time basis. Annual prices start at $34.95, while one-time subscriptions start at $89.95. Although it has a free version, the free version has a lot of restrictions.

For those who need more cleaning and optimization features, CleanMyMac is undoubtedly the best choice. However, for the average user who only wants to use some of these features but has to pay a high price, CleanMyMac may not be ideal. Therefore, more and more people are looking for alternatives to CleanMyMac.

So what are the best CleanMyMac alternatives? Keep reading, and you will find what you want below.

## Back up Your Mac

First things first, you should back up your Mac. When you reinstall a macOS, all the data on your Mac will be wiped out. If you have backed up the things that are important to you, you can restore them quickly after reinstalling macOS.

## How to Downgrade to the macOS That Came with Your Mac

If you are running High Sierra or a later version of macOS and want to downgrade it to the version that shipped with your Mac when you purchased it, you can quickly do it through Mac's built-in macOS Recovery feature. You just need to make sure your Mac is connected to the network. Here're the steps:

1. Close and restart your Mac.
2. Hold down the Shift + Option + Command + R until you see the macOS Utilities.
3. On the macOS Utilities screen, select the Reinstall macOS option.
4. Click Continue and follow the instructions on the screen.
5. Select your startup disk and click Install. 
6. Your Mac will restart after the installation is complete.

![Reinstall macOS That Came with Your Mac](https://www.drbuho.com/str-api/uploads/reinstall_macos_shipped_with_f26d1e02d4.png)

<note notetype='Note'>Don't forget to back up your Mac before performing the reinstallation steps.</note>

## How to Downgrade macOS Using Time Machine Backup

Another way to downgrade your macOS is to use Time Machine Backup, but only if you have already backed up your previous macOS with Time Machine. 

Here's what you need to do.

1. Start your Mac and immediately hold down Command + R to start up from the built-in macOS Recovery system.
2. Keep holding these two keys until you see the Apple logo or other image.
3. In the macOS Utilities window, select Restore from a Time Machine backup and click the Continue button.
4. Select your Time Machine backup and click on Continue.
5. After the reinstallation process is complete, restore the files you backed up.

![Downgrade macOS with Time Machine Backup](https://www.drbuho.com/str-api/uploads/restore_macos_with_time_machine_backup_de8abcb3c4.png)

## How to Downgrade macOS Using a Bootable Installer

What if you don't have a Time Machine backup but still want to revert to an earlier version of macOS? Do not worry. We'll show you how to install a downgraded macOS by using a bootable installer. This method is more complicated than the two methods mentioned above. To help you understand better, we've divided the steps into 4 main parts. Let's have a look now.

### Part 1. Prepare an External Drive

You need an external drive of at least 14GB. Although macOS is about 12GB in size, you still need some extra space to store data. So please make sure that your external drive has enough space.

There might be other files in your drive. You'll need to format it.

1. Plug your hard drive into Mac.
2. Open the Disk Utility app via Spotlight.
3. Select your drive in the sidebar and click the Erase button at the top of the window.

   ![Erase External Drive](https://www.drbuho.com/str-api/uploads/erase_external_drive_c3844bcf82.png)


4. Name your drive as **myVolume** and choose a format your Mac supports from the Format drop-down menu. 
    - If your Mac uses HFS+, choose Mac OS Extended (Journaled).
    - If your Mac uses APFS, choose APFS.

    <note notetype='Note'>To check which format your Mac is using, open the Terminal app and type and run the command: `diskutil info /`.</note>

5. If the Scheme is available, select GUID Partition Map.
6. Click the Erase button and then click Done.

![Format External Drive](https://www.drbuho.com/str-api/uploads/format_external_drive_on_mac_446b65702f.png)

### Part 2. Download macOS Installers

If you have previously downloaded the version of macOS you are going to install, you just need to open the Apple Store and download it again.

If you want to downgrade to a version of macOS that you haven't downloaded before, you won't be able to download it in the Apple Store. At this time, you can refer to [this article](https://support.apple.com/en-us/HT211683).
### Part 3. Create Your Bootable Installer 

Now you have prepared the external drive and macOS installer. Let's create your bootable installer.

1. Connect your formatted hard drive to your Mac.
2. Open the Terminal app.
3. Enter and run a command like below. (The command will vary depending on your version of macOS. Let's assume that the installer is located in your Applications folder and **myVolume** is the name of your external drive. If your drive has a different name, replace **"myVolume"** with the name of your external drive.)
    - **Big Sur**: `sudo /Applications/Install\ macOS\ Big\ Sur.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume`
    - **Catalina**: `sudo /Applications/Install\ macOS\ Catalina.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume`
    - **Mojave**: `sudo /Applications/Install\ macOS\ Mojave.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume`
    - **High Sierra**: `sudo /Applications/Install\ macOS\ High\ Sierra.app/Contents/Resources/createinstallmedia     --volume /Volumes/MyVolume`

    <note notetype='Note'>If your Mac is using macOS Sierra or earlier, don't forget to include the `–applicationpath` argument and installer path.</note>

4. Enter your password and press the Return again.
5. Follow the instructions that appear in the Terminal.
6. When you see Done in the Terminal, exit the Terminal and eject your hard drive.

![How to Create a Bootable Installer](https://www.drbuho.com/str-api/uploads/how_to_create_bootable_installer_bb60d64baa.png)

### Part 4. Install macOS with Your Bootable Installer

Finally, you're ready to install your macOS.

1. Plug your hard drive into Mac. (Make sure you have an internet connection.)
2. Click the Apple icon > Restart.
3. If you're using an Intel-based Mac, hold down the Option/Alt key until you see the Startup Manager window. If you're using an M1 Mac,  hold the power button while rebooting Mac.
4. Click on your external drive to select it as your startup disk. Your Mac will start up in Recovery Mode.
5. From macOS Utilities, select Disk Utility.

    ![disk-utility-macos-recovery-mode.png](https://www.drbuho.com/str-api/uploads/disk_utility_macos_recovery_mode_2b169eb158.png)

6. Erase everything on your Mac and quit Disk Utility.
7. Select Reinstall macOS > Continue.
8. Follow the instructions to install your macOS with the bootable drive you created.

<note notetype='Note'>Macs with M1 chips do not support macOS versions earlier than macOS Big Sur.</note>

## 3. CCleaner

It is professional but easy to use, and it can not only [speed up](https://www.drbuho.com/how-to/speed-up-mac-monterey) your Mac but also protect it. Although there is a free version of CCleaner, it only has two basic functions. They include "faster computers" and "privacy protection".

The main drawback of Disk Doctor is that it only scans attachments from the Mail app, ignoring various desktop email clients. While other software uses a secure erase program, Disk Doctor uses a basic program that cannot permanently delete files.

## What Spotlight Can Help You Do

Spotlight is a handy search feature on macOS. It allows you to quickly find apps, documents, and other files. With Siri's suggestions below the results list, you can also get the news, videos, articles, and more about the keyword you're searching for. In addition, Spotlight can perform calculations and conversions for currency, temperature, and measurement.

## How to Reindex Spotlight on Mac

In recent years, Apple has enhanced this feature to make it easier to use. Sometimes, however, you can't use Spotlight to find the file you're sure is stored on your Mac. The reason for the problem may be that your system is blocking Spotlight from searching the folder where the file is located. To check if a file is prevented from being searched, click **Apple menu > System Preferences > Spotlight > Search Results**. The deselected folders in the list will not appear in the Spotlight search results. 

![How to Check Spotlight Search Results](https://www.drbuho.com/str-api/uploads/check_spotlight_search_results_25cbeda6e9.png)

If you have confirmed that the file is included in the search result, but you still can't find it through Spotlight, it means your index may be damaged, and you need to reindex your Spotlight. In the following sections, we will show you how to rebuild the index of Spotlight in two simple ways. Let's take a look now.

You can take some steps to fix it. In this blog, we will take you through why apps keep crashing on Monterey and teach you how to solve the problem.

:a[How to Delete the "Other" in Mac Storage]{href='https://www.drbuho.com/how-to/clear-other-storage-mac'}

:::

## Reasons for Apps Keep Crashing on Monterey

After upgrading to macOS Monterrey, various problems may occur. The most common one is app crashes. There are many reasons for this problem. Here we have listed some of the most important ones:

- Apps are not compatible.
- Running out of memory space.
- Too many processes in the background.
- Bugs in apps.

Fortunately, app crashes do not affect your Mac much. You can try some tricks to fix the problem.

## How to Fix App Crashing on Monterey

Now that you know the possible reasons for the app crash. Let's see how to solve this problem.

### 1. Force Quit the Crashing App & Restart It

After an application crashes or freezes, the simplest solution is to force quit it and start it again.
You can do this by clicking the Apple Menu > Force Quit, finding the crashing app in the list, selecting it, and then clicking the Force Quit button to end all the app processes. After that, restart your app.

![Force Quit the Crashing App](https://www.drbuho.com/str-api/uploads/force_quit_app_ea6d8a840f.png)

If you restart the application, the system still prompts that the app has quit out unexpectedly, then you can proceed to the next step.

### 2. Restart Your Mac

It's a good idea to reboot your Mac. Some common problems can be solved by restarting your Mac. All you have to do is click on the Apple Menu and select Restart.

If the crashing problem still occurs, then try the following methods.

### 3. Update Your App

If an application is not compatible with your current Mac operating system, it will crash. What you should do is update the application to a version compatible with Monterey.

For an app downloaded from the Apple Store, open the Apple Store, click Updates in the sidebar, and update the application.

![Update App with Apple Store](https://www.drbuho.com/str-api/uploads/update_apps_apple_store_50b86aadf6.png)

For an app downloaded from the Internet, you cannot update it through the Apple Store. You need to go to its official website to check if there is a new version. If so, follow the instructions on the screen to update. If not, you have to wait for a new update before you can use it again. Of course, you can also find a compatible alternative.

### 4. Kill Memory-Hogging Processes 

As we said above, insufficient memory space can also crash your app because your app has no space to store data. In this case, you can use Activity Monitor to find and end processes that are memory hungry, such as graphics design tools, video editing software, and other large programs.

1. Open Activity Monitor via Spotlight or Launchpad.
2. Click on the Memory tab, and you will see all the processes that are using your memory.
3.  Find the ones that take up a lot of space and double-click on their icons to stop them.

![Kill Memory-Hogging Processes with Activity Monitor](https://www.drbuho.com/str-api/uploads/stop_processes_with_activity_monitor_250648f4ad.png)

### 5. Clear App Cache

An app cache contains files, images, multimedia, java scripts, and other data. Cache files can speed up the loading of an application when you revisit it. If you are experiencing a crashing problem with your application, clearing the app caches may help you fix the issue. Don't worry. Clearing cache files will not harm your app. It will only make the app load slower than before.

To clear an app's cache, press Shift + Command + G on a Finder window to open the Go to Folder window, paste the folder location **~/Library/Caches**, and click the Go button. Find the crashing app's folder in the Caches folder, go into it, and drag files inside to trash.

![clear-app-cache.png](https://www.drbuho.com/str-api/uploads/clear_app_cache_2980811ffc.png)

### 6. Uninstall and Reinstall the Crashing App

Still can't solve the app crashing problem by the above methods? Try to uninstall and reinstall it.

Please note that it's essential to uninstall the crashing app completely. Simply dragging the app to the trash won't thoroughly remove it from your Mac. Its associated files are still on your hard drive. To entirely remove the application, you also need to find and delete its related files using Finder.
1. In the Finder, click the Go menu and then select Library.
    ![go-to-library.png](https://www.drbuho.com/str-api/uploads/go_to_library_8be76650d7.png)  
2. Check the following folders to the app-related files.
- Application Support
- Caches
