Windows Migration Assistant transfers your contacts, calendars, email accounts, and more from a PC. It migrates this data to the appropriate places on your Mac. After migrating data to your Mac, authorize your computer for iTunes Store purchases. It’s important to authorize before you sync or play content that you download from the iTunes Store.

If you're migrating from one Mac to another Mac, follow the steps to move your content to a new Mac.

Before you begin

However, there are some specific programs that are currently incompatible with Snow Leopard–so incompatible, in fact, that 10.6’s installer will move them into a folder called Incompatible. When you install OS X, you may see a new folder at the root of your boot drive called 'Incompatible Software,' which may contain a program file or perhaps a folder of program components.

To prepare for a smooth migration:

• Make sure that Windows is up to date. Migration Assistant works with Windows 7 and later.
• Make sure that you know the name and password of an administrator account on your PC.
• Connect your Mac and PC to the same network, such as your home Wi-Fi network. Or connect an Ethernet cable between the ports on your Mac and PC to create a direct network connection. Some Mac models require an Ethernet adapter, such as the Belkin USB-C to Gigabit Ethernet Adapter or Apple Thunderbolt to Gigabit Ethernet Adapter.
• If you're using Microsoft OneDrive on your PC, follow Microsoft's instructions for uninstalling OneDrive before continuing. You can reinstall OneDrive after migration is complete.

Then use the check disk (chkdsk) utility on your PC to make sure that your Windows hard drive doesn’t have any issues:

1. Right-click the Start button, then click Run.
2. Type cmd and press Enter. Command Prompt opens.
3. At the prompt, type chkdsk and press Enter.
4. If the utility reports that it found problems, type the following, where drive is the letter that represents your Windows startup disk, such as D:
   
5. Press Enter.
6. At the prompt, type Y, then restart your PC.
7. Repeat this process until the check disk utility reports no issues. If the utility can't fix every issue that it finds, you might need to have your PC serviced. Then migrate your data to your Mac.

Move your data

This section guides you through migration, post-migration, and what to do if the steps don’t work for you.

How to move your information from a PC to your Mac

1. On your PC, download and install the appropriate Windows Migration Assistant, based on the version of macOS on your Mac:
   • Windows Migration Assistant for macOS Big Sur
   • Windows Migration Assistant for macOS Mojave and macOS Catalina
   • Windows Migration Assistant for macOS Sierra and High Sierra
   • Windows Migration Assistant for OS X El Capitan or earlier
2. Quit any open Windows apps.
3. Open Windows Migration Assistant, then click Continue.
   
4. Start up your Mac. Setup Assistant automatically opens the first time you turn on your Mac. If you’ve already set up your Mac, open Migration Assistant, which is in the Utilities folder of your Applications folder.
   
5. On your Mac, follow the onscreen prompts until you get to the migration pane of the assistant. Select the option to transfer your information “From a Windows PC,” then click Continue.
   
6. When prompted, enter an administrator name and password.
7. Click Continue to close any other open apps.
8. In the migration window on your Mac, select your PC from the list of available computers. Then wait for the PC to show the same passcode that your Mac shows.
9. When both computers display the same passcode, click Continue on your PC and Mac.
10. Your Mac scans the drives on your PC to build a list of information to migrate. When the scan completes, select the information that you want to migrate to your Mac and click Continue. Learn about some of the data that you can transfer.
    

You can watch the progress and estimated time remaining on both the PC and your Mac. They tell you when migration is complete.

After you move your data

When migration completes, close Windows Migration Assistant on your PC. Then log in to the new user account on your Mac. The first time you log in to a user account migrated from your PC, you’re asked to set a password. You can use the same password that you used on your PC, or create a new password.

After logging in to the user account that you migrated, authorize your computer for iTunes Store purchases. It’s important to authorize before you sync or play content downloaded from the iTunes Store.

If you have issues moving your data

• Quit all open apps on your PC, then try migrating your content again. For example, you can press Alt-Tab to choose an open application, then press Alt-F4 to quit it.
• If your PC doesn't appear in the Setup Assistant or Migration Assistant window on your Mac, make sure the computers are connected to the same network. You can create a network by connecting a single Ethernet cable between your Mac and PC. If that doesn't help, check for firewall software on your PC and turn it off. After migration completes, you can turn firewall software on again.
• If Migration Assistant doesn’t open on your PC, turn off any antivirus software on your PC. Then try to open Migration Assistant again. After migration completes. You can turn that software on again.
• If you still can't migrate your information successfully, you can use an external drive or file sharing to manually copy important data to your Mac.

What data can I transfer?

Migration Assistant lets you choose the data to move to your Mac. Here’s what moves over for specific apps and data types:

Email, contacts, and calendar information
Email messages, email-account settings, contacts, and appointments move based on which version of Windows you're using and which accounts you have.

Apple’s latest macOS, Catalina, has just been released to the public last October 7, 2019 and you can now install it on your Mac, as long as your device meets the hardware requirements. First revealed during the WWDC 2019 conference in San Jose, California, macOS Catalina introduces some new exciting features and functionalities.

As we say goodbye to iTunes, macOS Catalina brings in new apps and features to the table, including Apple Music, Podcasts Books, and TV. Another major feature is Sidecar, which can turn your iPad into another display. For ordinary users, this means getting a secondary display for free. For developers, on the other hand, this secondary screen can be used as a drawing tablet using supported apps.

With the release of macOS Catalina 10.15, a lot of Mac users are enthusiastic to install the newest Mac operating system. Just like the previous versions of macOS, some were able to upgrade without a hitch, but several users encountered various issues during downloading and installation of the update.

Some users experienced slow downloading of the update, while others got error messages when installing Catalina, including:

Pro Tip: Scan your Mac for performance issues, junk files, harmful apps, and security threats
that can cause system issues or slow performance.

• Storage system verify or repair failed
• This copy of the Install application can’t be verified. It may have been corrupted or tampered with during downloading.
• An error occurred while preparing the installation. Try running again.
• Copy of install macOS application is damaged and can’t be used to install macOS.
• There is not enough free space on the selected volume.

This guide will give you a detailed rundown of the most common macOS Catalina installation and update errors encountered by Mac users when upgrading or installing macOS Catalina, along with the instructions on how to deal with these hiccups.

Why macOS Catalina Won’t Install

Various problems can occur during the installation of macOS Catalina. If the installation won’t start, seems to freeze midway , or never seems to complete, then it means that there must be something wrong somewhere.

The first main reason why users can’t install macOS Catalina is compatibility problem. If your Mac doesn’t support macOS Catalina, you won’t be able to proceed with the installation. You need a fairly recent Mac to be able to run macOS Catalina. Here are the Mac models that support the newest macOS:

• MacBook (2015) and later
• MacBook Air (2012) and later
• MacBook Pro (2012) and later
• Mac Mini (2012) and later
• iMac (2012) and later
• iMac Pro (2017) and later
• Mac Pro (2013) and later

If your device is not on this list, then you’re sure to run into problems when installing Catalina.

Another thing you need to check before installation is your available storage space. You will need around 6.5 GB just to download the installer. Once you’ve downloaded it, the amount of space you will need during the installation depends on whether you’re doing a clean install or an upgrade.

A clean install will eat up around 20 GB of storage. On top of that, you have to make room for apps, user data, and user updates. An upgrade install, on the other hand, will only take up 6.5 GB of space for the installer, plus some installation files that the installer will copy to your startup drive.

If you’re tight on storage space, you should consider removing unneeded apps and files on your Mac. You can uninstall the apps one by one, and delete cache files and data using Outbyte MacRepair. Make sure you have at least 25 GB of free space to be able to install macOS Catalina successfully.

Aside from compatibility issues and insufficient storage, poor internet connection, incomplete or corrupted installation files, hard disk problems, and faulty software can also cause issues during the installation of macOS Catalina.

Installation Checklist for macOS Catalina

Before proceeding with the installation, it is necessary to spend some time ticking off the checklist below. These steps will not only prevent errors from happening, but also ensure that your data remains safe in case something goes wrong.

• Back up your Mac, especially your iTunes media library since Catalina will no longer have iTunes.
• Take note of the 32-bit apps on your Mac . You will need to update them to the 64-bit version after upgrading, or find an alternative for them.
• Delete old Install macOS files from your Applications folder. These old macOS installation files may cause error during the upgrade.
• Remove all external drives and accessories.
• Plug in your Mac’s power adapter.
• Connect to a stable Wi-Fi network.

Once you’ve completed these steps, you can now proceed with the upgrade.

How to Upgrade to macOS Catalina

The easiest way to download and install macOS Catalina is through the App Store on your Mac. Just open the App Store and search for macOS Catalina. Click the install button to start downloading, then click Continue.

You can also visit the macOS Catalina website and download the installer from there. The installer will be downloaded to the Applications folder on your Mac. Once downloaded, the installer will open by itself. Just follow the onscreen instructions to proceed with the installation. You might be asked to log in using your admin username and password during the process.

As long as your device is compatible with Catalina and you’ve followed the instructions, you’ll be able to successfully install the new macOS on your Mac. But if you encounter any error during the download or installation, refer to our guide below to sort out the issue.

How to Fix Common Download Errors for macOS Catalina

Downloading the installer is the first step of the installation process. The installer takes up 6.5GB of storage, but you will need more space to be able to run the new macOS smoothly. If you have Automatic Updates enabled, the installer might already be downloaded on your device.

If the installer has not yet been downloaded, go to the Apple menu > System Preferences > Software Update to download Catalina.

If the downloading process gets stuck or is taking a long time to complete, here’s what you can do:

1. Go to the Apple Server status website and check if the macOS Software Update‘s button is green. If not, then there’s probably some issues with the website, so you might need to try upgrading some other time.
2. If the macOS Software Update is green, but you’re still having download problems, check your internet connection. Consider switching to a wired internet connection if possible.
3. If the download is stuck for a long time, cancel it by clicking the X button.
4. Switch to a different DNS server and retry the download again.

It might take a few attempts for the downloading to be successful, especially in the early days of the release of the update.

How to Fix Errors When Preparing for the Installation of macOS Catalina

Once you have successfully downloaded the installer to your device, the system then prepares your Mac for the installation process. There are users who encountered errors during this stage and came across the Error occurred preparing the installation. Try running the applicationagain message.

The first thing you need to do when you encounter this error is to reboot your Mac. You might need to restart your system a couple of times to deal with this problem. If the error doesn’t go away after rebooting, here are some steps you can try:

Check Your Mac’s System Date and Time.

An incorrect system time usually gets in the way of a lot of system processes, including updates. To make sure your Mac’s date and time are correct, follow the instructions below:

1. Go to the Apple menu > System Preferences > Date & Time.
2. Tick off Set Date and Time Automatically.
3. If the option is already checked, uncheck it then reboot your Mac.
4. Go back to the Date and Time panel and check the option again.
5. Next, try re-installing macOS Catalina.

Re-Download the Installer.

If the step above did not work, you might have to delete the macOS Catalina installer on your Applications folder. Find the Install macOS file in the Applications folder and move it to the Trash. Empty the Trash and reboot. Once your Mac restarts, try downloading the installer and then run the install process again.

Delete the Installinfo.plist File.

If you encounter the Copy of install macOS application is damaged and cant be used to install macOS error during the preparation of the installation, the best workaround is to delete the installinfo.plist from the installer package, then try re-installing.

To delete the installinfo.plist file, check out the steps below:

1. Go to the Applications folder and look for the installer package for macOS Catalina. It is usually named Install macOS.
2. Right-click on the file and select Show Package Contents.
3. Click on Contents > SharedSupport.
4. Delete the Installlnfo.plist inside the folder.
5. Type in your admin password to confirm the action.
6. Click on the installer to run it again.

How to Fix Catalina Installation Errors on Mac

After preparing your Mac, the system then proceeds to the installation process. There are different errors you might encounter at this stage, so you need to take note of the error message and at which stage it happened.

Here are some of the errors you may encounter during the installation process.

Stuck at Setting Up Screen

When you’ve been stuck with the Setting up your Mac message for several hours or you encounter the dreaded spinning wheel, the best way to deal with this is to restart your device. Press the power button to shut down your Mac, then press it again to reboot.

Storage Space Problems

If you failed to optimize your storage space before the installation, you might come across errors related to insufficient storage space. You might see the macOS Could not be installed, the target disk is too small message or the There is not enough free space on the selected volume error.

This happens because you do not have enough space on your Mac. Free up some storage first before proceeding with the installation. You might need around 20GB to 25GB of space for macOS Catalina to run efficiently on your Mac.

Network Access Error

If you see a Code=551 error anytime during the installation process, you need to check your network settings. This error happens to devices with overactive firewall or those installed with third-party security software, such as VPN and antivirus. If this happens, disable this software first before trying to reinstall macOS Catalina.

Installation Doesn’t Complete

Sometimes, your Mac gets stuck with the x minutes remaining screen during the installation. When you encounter this problem, click the X button to exit the installation process and check your console logs. It is possible that your user account is corrupted, preventing your system from completing the installation process.

The only way to deal with this is to create another admin user account and install macOS Catalina using that account.

Mac Fails to Start After Update

You might think that everything is over once you finish the installation process and your Mac restarts. But sometimes, errors can still happen even after the installation has been completed. Some users reported getting stuck with a black screen, while others encounter the spinning wheel during the restart following the update.

This error is usually caused by incompatible or corrupted kext files. Kext or Kernel Extension files are the drivers for macOS. To check whether kext files are causing the error, move all of them out of your Extensions folder before rebooting your Mac.

To move your kext files, follow the steps below:

1. Boot your Mac into Safe Mode by holding down the Shift key until you see the Apple logo.
2. Open Terminal under the Utilities folder, then copy-paste the following command:

mkdir ~/Extensions-Backup && sudo mv /Library/Extensions/* ~/Extensions-Backup/

Once done, restart your Mac in normal mode and see if it goes through.

If All Else Fails, Do a Fresh Install.

If you’re still having issues despite following the guide above, you may need to do a fresh install of macOS Catalina. To do this:

What Is Incompatible Software On Mac

1. Shut down your Mac.
2. Press Power + Command + R keys to bring up the macOS Utilities screen .
3. Click Reinstall macOS.
4. Select Disk Utility > Erase HDD.
5. Install the macOS Catalina from here.

Remember that erasing your HDD will delete all of your files and settings, so make sure you have a backup before doing a fresh install. This should hopefully take care of common macOS Catalina installation problems.
