A fresh start is not a challenge in the Mac universe. Quite the opposite, getting a macOS upgrade every September marks a surge of new features and functionality enhancements—all coming right your Mac’s way.

Where can I order the OS X media for 10.13, like a DVD in a physical box, or download the image file from Apple? The Apple Website directs me to the App Store, and the App Store is refusing to allow the download. I need a way to get the ISO image so that I can copy it to a bootable disk without going through an existing OS X installation.

  • I am currently researching installing OS X 10.13 High Sierra on unsupported Macs. I did the Sierra upgrade on a couple of MacPros 4,1 and it has worked excellently, after I did a firmware update patch to get it to read as a MacPro 5,1, so I am very optimistic on doing it again.
  • After you download the macOS 10.13/10.13.4 upgrade software, install the software and update Mac computer to macOS 10.13 or 10.13.4 High Sierra by following the on-screen instructions. If no update problems occur, restart your Mac computer and enjoy the new macOS on your device.

Apple introduced the perks of macOS 10.15 at the 2019 WWDC, and lots of features have been tested and discussed since then. A dual monitor available with the Sidecar feature, the Photos app update, and a brand-new iTunes made the show this year. Lots of features migrate from iOS, the others appear for the first time. If you’re wondering why Catalina is worth an upgrade, check the full list of killing features here.

Traditionally, there are two stages at which you can try macOS Catalina before it’s officially released. Starting June, there’s a developer beta available, and about a month later—a public one.

Ready to dive in? Give us a second to get you ready.

10.13

Take all your apps to macOS Catalina

Get Setapp, a suit of Mac apps that strengthen your macOS. When you decide to upgrade, your curated apps will travel with you.

A few things before you switch to Catalina

Your to-do list for the upcoming upgrade:

Upgrade To Os X 10.13
  1. Ensure your device is compatible. As usual, there’s a limited number of Apple devices that support macOS 10.15. It’s not too different from what we had last year, but take a look anyway. Sometimes the reason why you can’t upgrade lies on the surface:

    • MacBook Air (2012 or newer)
    • MacBook (2015 or newer)
    • MacBook Pro (2012 or newer)
    • Mac Pro (2013 or newer)
    • Mac mini (2012 or newer)
    • iMac (2012 or newer)
    • iMac Pro (all models)
  2. Say goodbye to 32-bit apps. Mojave was the first macOS to stop admitting 32-bit apps to the App Store and the last to support them. In Catalina, you’ll have to limit your Mac to 64-bit applications only. Once you install macOS 10.15, you’ll be warned about 32-bit apps not working on your Mac any longer. CleanMyMac X will help you quickly filter applications by 32-bit and get rid of them:
  3. Backup valuable data. When we’re too excited, we tend to rush things. Remember though, that a new macOS means a new start—wiping away the past. To keep your data safe, create a backup before upgrading. You can use Apple’s in-built Time Machine or more advanced tools like Get Backup Pro if you want a bootable backup.
  4. Clean up your Mac. You need to free up some space for your new macOS. Even if you have enough, running a cleanup is a nice way to start a clutter-free life in Catalina. From redundant apps to caches and leftovers, you can remove any unnecessary items with CleanMyMac X.

How to install a developer beta of macOS Catalina

Downloading and installing macOS Catalina developer beta is an easy deal if you have a Developer account. Here’s how it works:

  1. Go to developer.apple.com and click Account in the top menu bar.
  2. Sign in with your account credentials.
  3. Select Downloads > Install Profile.
  4. Find and launch the installer in your Downloads folder.
  5. Open the PKG file and agree to the installation.
  6. If required, verify the account by entering your system password or with Touch ID.
  7. Find the update in System Preferences.
  8. Click Upgrade Now to install the beta.

Test macOS 10.15 on a partition

If you’re not ready to give up Mojave just yet, you can install Catalina on a partition. Basically, it allows to split your disk into two parts, so that your computer can run two operating systems at the same time.

To install Catalina on a partition, go to Applications > Utilities > Disk Utility. Your disk will be the first on the list under “Internal.” Select the disc and navigate to Partition tab. Click the plus button to split your disk, name your partition, and customize the size if needed. Click Apply and you’re ready to drive. Or, rather, double drive.

Clean install macOS Catalina on Mac

If you’re determined to give your Mac a new life, run a clean install of Catalina. In contrast to a regular install which puts macOS on top of your startup disk content, a clean installation cleans everything up. Risky as it sounds, a clean install enables a healthier life for your macOS. Just make sure you don’t lose anything in the shuffle:

  1. Create a safe bootable backup of your disk with Get Backup Pro.
  2. Connect a clean and reformatted external hard drive or a USB stick.
  3. On the disk, create a bootable installer.
  4. Erase your startup disk with Disk Utility and boot from the new one.
  5. When installing macOS Catalina, choose your new disk as the install location.
Upgrade os x 10.10 to 10.13

If you decide to go with a regular install, note that all the clutter from your disk will be transferred to the new operating system. So we recommend to make use of CleanMyMac X smart scanning before you upgrade.

Download and install Catalina Public Beta

A developer beta opens up an early access to all the features. The problem is it’s not free. To get your hands on Catalina with a developer account, you have to pay a yearly fee of $99. Therefore, you might want to wait for Apple to make it public.

Arriving in July, a public beta of Catalina is available at beta.apple.com/sp/betaprogram/. Once there, it takes a couple of steps to upgrade:

  1. Log in with your Apple ID.
  2. Navigate to Enroll your Mac section and click on “Download the macOS Public Beta Access Utility.”
  3. Once downloaded, run the installer.
  4. Open System Preferences. You’ll find the public beta update under Software Update (macOS Catalina beta).
  5. Click Upgrade now to download the installer. Go through the installation if you want to put beta on your current Mac, or quit to create a bootable USB install drive first.

The pitfalls of Catalina beta

To put it shortly, it’s buggy. Just like any other macOS beta, Catalina can slow down your Mac, freeze, or hinder the work of some apps. It’s ok.

There are a couple of things you can fix, though:

  • If you have issues with Sidecar: Ensure your iPad runs on the new iPadOS beta. The feature won’t work on iPadOS 12.
  • If an app doesn’t open: Hope you remember, 32-bit apps are dead in Catalina. So if some of your software doesn’t work on the new macOS because of 32-bit architecture, look for alternatives.
  • If iCloud doesn’t work properly: Try to close and reopen a document, or download files manually if iCloud Drive fails to load them.

Once you notice imperfections, help to fix them. Beta users can report bugs through Apple’s in-built Feedback Assistant app.

Hopefully, Catalina is worth an upgrade for you. If not, you can downgrade anytime to continue your journey with Mojave. If an operating system doesn’t solve some of your tasks, let Setapp cover the needs. It’s a curated collection of Mac apps that helps you with screenshots, PDF editing, file management, and tons of other jobs—150 at the very least.

macOS 12 Monterey Update Problems and Fixes

Update to macOS 12 Monterey is not always smooth. Some known issues already happen during the download and install. First of all, let's exclude some basic reasons that may cause Monterey update errors. First of all, check if your Mac is compatible with the new system; second, make sure your Mac has enough storage for Monterey. Open the Apple menu and click About This Mac > select Storage and check if there is at least 16GB free space.

1. macOS 12 Monterey installation failed

'Installation failed. In order to continue installing, you need to be an owner.' Many early users have reported this error when they update from macOS 11.4 to 12 Monterey. Some other users also get Monterey update error messages like 'cannot be installed because of an error.' To fix the error 'Failed to get ownership for system', you can:

Upgrade To Os X 10.13

  1. Press cmd + Spacebar to bring up Spotlight and search for Terminal.
  2. sudo softwareupdate -i -a -R
  3. -i Install
  4. -a All appropriate updates
  5. -R Automatically restart (or shut down) if required to complete installation)

2. Can't install macOS Monterey on M1 Macs

10.11.4

Many users of M1 Macs says they they can't install macOS Monterey on their M1 machines. For example, some get the message 'An error occurred while setting 'Monterey' as the startup disk: The operation couldn't be completed. (SDErrorDomain error 108.)'. Luckily, some other M1 owners have provided useful solutions to fix it:

  • Installing the macOS 12 Monterey from inside the recovery mode:

    1. Download the Monterey installer app onto your internal SSD.
    2. Boot the M1 Mac into recovery mode by shutting it down first and pressing + holding the Touch ID key.
    3. Connect the external drive and format it using Disk Utility; choose APFS as file system.
    4. In the recovery mode, open Terminal, navigate to where the Monterey installer is stored (like ~/Downloads on your internal disk)
    5. Start the installation process by executing ./Install macOS 12 Monterey.app/Contents/MacOS/InstallAssistant

  • Try another USB-A-port instead of the USB-C port. Try another external drive.
  • Reset PRAM/ NVRAM and SMC [For intel Mac only]

3. Failed to personalise the update. Please try again.

Here is another common error during macOS 12 Monterey update - 'An error occurred preparing the update. - Failed to personalise the software update. Please try again.' The 'Failed to personalize' error is not new with Monterey. Here are some fixes:

  • Installing the macOS 12 Monterey using Terminal Commands as per the guide above. Use sudo sh -c 'softwareupdate -ia' via terminal.
  • Update macOS 11 Big Sur to 12 Monterey in Safe Mode: Power off your Mac > Turn it back ON and immediately press & hold the Shift key > Only release Shift after the log-in screen is displayed. Type your Password. > Go for System Preferences -> Software Update and try to update again.

4. macOS Monterey update not found

Get the macOS 12 update error 'Update Not Found - The requested version of macOS is not available.'? You're not alone. Why your Mac says the requested version of macOS is not available? You can try:

  • Command + R from the updates window to force a refresh.
  • Opten terminal and follow the steps:
    sudo -i
    enter root password
    /System/Library/PrivateFrameworks/Seeding.framework/Versions/A/Resources/seedutil

    Unenroll from the Beta Program
    /System/Library/PrivateFrameworks/Seeding.framework/Versions/A/Resources/seedutil unenroll

    Enroll in the DeveloperSeed Beta
    /System/Library/PrivateFrameworks/Seeding.framework/Versions/A/Resources/seedutil enroll DeveloperSeed

    Close and re-open System Preferences > Software Update

  • There is too much traffic on the server. Try to update Monterey another time.

5. Monterey install is stuck

Updating to macOS Monterey 12 from macOS Big Sur might take significantly longer than expected. There are users who tried to download Monterey installer via system update for hours. But Monterey download gets stuck and the progress bar stops at some point like 25% or even 100%. Some others get stuck on 'Preparing macOS Monterey 12.1 Update...' Rebooting and re-downloading the system won't fix.

  • Shut down your computer, restart it and hold down the shift button until it starts in safe mode. Then redownload Monterey.

  • Clear the local snapshots of Time Machine stored locally on your Mac. To do this, choose Apple menu > System Preferences, then click Time Machine. Turn off 'Back Up Automatically'. If that doesn't work, then delete the snapshots manually in the terminal: type tmutil listlocalsnapshots / and then type sudo tmutil deletelocalsnapshots 2020-06-01-002010;
  • Sign out from AppStore -> Restart Mac -> Sign in to AppStore -> Download Xcode;
  • Download the installer on an external hard drive and try again.
