Apple's newest macOS version is set to launch this October, and I'm thrilled about the array of exciting features it will introduce. I've been testing the beta version of Ventura on an external Thunderbolt drive, and I must say, it's impressive. Apple has implemented some great enhancements.

However, before upgrading to Ventura, there are several key preparations to ensure your system is ready.

Verify Compatibility with Ventura

Not all Macs are eligible for the latest macOS. The models that officially support macOS 13 Ventura include:

• iMac, 2017 and later
• iMac Pro, 2017
• MacBook Air, 2018 and later
• MacBook Pro, 2017 and later
• Mac Pro, 2019 and later
• Mac Studio, 2022
• Mac Mini, 2018 and later
• MacBook, 2017

Unfortunately, Macs manufactured in 2016 or earlier cannot run this release without third-party patching tools. The silver lining is that if your device isn’t compatible with Ventura, it will still receive support for Monterey for a while.

Create a Recent Time Machine Backup

Time Machine is one of macOS's standout features. I love being able to connect my external SSD for automatic backups, preserving my files and settings effortlessly. It’s both convenient and efficient.

Before undertaking any significant system changes, such as upgrading to Ventura, ensure you have a reliable backup. This advice extends to Windows users as well; taking a few moments to secure a dependable backup is always better than discovering too late that you don’t have one when it’s critical.

Trust me — I’ve faced that situation many times, and it's a distressing experience.

While backing up with Time Machine won't directly influence the success of your Ventura upgrade, it provides a fallback option in case something goes wrong during the installation.

Run First Aid on Your Startup Disk Using Disk Utility

Apple's Disk Utility is a handy tool for performing maintenance on both internal and external drives. You can find it in your Utilities folder.

The First Aid feature checks your drive and filesystem for issues and attempts to resolve them. Regular checks are advisable, especially before a major OS upgrade.

Experiencing a failure due to disk or filesystem corruption can quickly dampen your upgrade excitement. I've encountered this on both Mac and Windows systems.

Running a quick filesystem check before your upgrade is always prudent to ensure there are no significant issues that need addressing.

Remove Unused Applications

If you're anything like me, you likely have several applications that you no longer use or need.

Before upgrading your OS, it’s wise to sift through your applications and eliminate any that are unnecessary. While installed apps typically won’t interfere with the upgrade, clearing out unused programs is a good practice.

I recommend using AppCleaner, a free tool that helps identify leftover files from apps uninstalled in the conventional manner. While other similar apps are available, this one has served me well.

Check for Updates on Your Remaining Applications

Post-upgrade, some of your applications may not function correctly or may not open at all without updates from their developers. Some may never receive compatibility updates, while others may already have been updated.

For apps downloaded from the App Store, checking for updates is easy — simply click “Updates” on the left side of the App Store window on your Mac.

For applications from other sources, you will need to check with their respective developers or app stores. Some apps have an in-built “check for updates” feature, while others, like those in the Adobe suite, rely on a separate application for updates. For certain programs, visiting the developer’s website may be necessary.

Skipping this step may lead to issues after installing macOS Ventura, as some apps might not work as intended.

Ensure Sufficient Disk Space

To download and install the update, you will need adequate space on your local disk. Ensure you have at least 25GB of free space available. The installer for macOS Ventura is about 12GB, so having double that space is advisable for the installation process.

If your Mac's startup disk is limited in size, you may need to uninstall some applications or transfer data to create sufficient space.

On macOS Monterey, you can check your available storage by navigating to the Apple menu > About This Mac > Storage.

Clicking the “Manage…” button provides an overview of what is consuming your storage. It’s wise to periodically review this to eliminate unnecessary files.

For more detailed insights, there are various applications, such as Disk Inventory X, that can help you analyze your storage usage for informed decision-making.

Charge Your Battery (If Applicable)

Although macOS prevents installations without a power source, it’s still wise to ensure your battery is adequately charged before beginning the upgrade.

In the unlikely event of a power loss during the installation, you want to avoid the risk of having an unbootable machine.

This consideration primarily applies to laptops; desktop users should consider having a backup battery for important tasks, despite their bulkiness.

Familiarize Yourself with New Features and Changes

Each macOS version introduces new features and improvements, and Ventura is no exception. Before you install the update, take some time to learn about the new functionalities and layout changes.

For instance, System Preferences has been renamed to System Settings in Ventura, and the interface has been updated.

This new settings layout is user-friendly and should be easier for less tech-savvy users to navigate. However, if you're accustomed to the older layout, it may take some adjustment.

It's beneficial to familiarize yourself with these and other changes ahead of the upgrade to avoid surprises.

Consider Delaying Your Upgrade

As a tech enthusiast, I've experienced various operating systems, and a common theme is that bugs are inevitable. You can expect them.

When Windows 11 first launched, I opted not to upgrade my Dell immediately because I knew from experience that there would be bugs. And indeed, there were. Microsoft took time to resolve several issues, and some are still being addressed.

At present, macOS Ventura has undergone multiple beta tests, but even the most thorough testing may not catch every bug. Some problems only arise once the OS is widely adopted, and users report issues.

As a general guideline, it’s wise to wait at least a week before upgrading a primary machine to a new OS. If you have a spare Mac available or are comfortable restoring from a backup in case of problems, upgrading right away should be fine.

As for me? I plan to hold off for a little while.

Additionally, developers may require extra time to update their software for compatibility with macOS Ventura, and they might not have their updates ready on launch day. Unless you have confirmed that all essential applications will function correctly with macOS Ventura, waiting a few days or weeks before upgrading your primary device could be prudent.

Anticipating macOS 13

Apple's upcoming macOS version promises a wealth of new features and enhancements. Personally, I look forward to using my iPhone as a webcam and the new security features on offer.

Apple is expected to unveil Ventura this October.
