Why Popular Mac Apps 

Mac apps struggling on Sonoma are usually affected by outdated app versions, changed security requirements, permissions, drivers, or system-extension behavior rather than a universal Sonoma incompatibility. Reunion, SABnzbd, and SoftRAID are good examples: older versions can cause trouble, while newer supported releases can work properly on modern macOS.

Are Reunion, SABnzbd, and SoftRAID Actually Broken on Sonoma?

No. It is more accurate to say that specific versions or configurations can experience macOS Sonoma compatibility problems. Current software should always be checked against the developer’s compatibility information instead of assuming the entire application is unsupported.

This distinction matters. A user experiencing crashes after upgrading macOS may have an outdated build rather than an application that has permanently stopped supporting Mac computers.

Why Do Mac Apps Struggle After macOS Updates?

Major macOS releases can expose dependencies on older APIs, permissions, drivers and extension technologies. Apple has progressively moved developers away from legacy kernel extensions toward newer system-extension frameworks because kernel-level extensions carry greater security and reliability risks.

Apple also requires additional approval for some legacy system extensions. On Apple Silicon Macs, certain kernel-extension configurations can require changes to startup security settings. This particularly matters for utilities that operate close to storage, networking or other system-level functions.

That does not mean every app problem is caused by kernel extensions. Applications can also encounter problems because of outdated dependencies, changed permissions, file access, background processes or unsupported versions.

Reunion and macOS Sonoma: Is It Compatible?

Reunion compatibility depends on the version. Leister Productions specifically states that Reunion 12 has compatibility issues with macOS Sonoma and recommends upgrading rather than continuing to depend on that legacy version.

The situation is different for newer releases. Reunion 13’s latest build was reported by the developer as running on Sonoma, while Reunion 14 is the current generation and supports substantially newer macOS releases as well.

What should Reunion users do?

• Check which Reunion version is installed before upgrading macOS.
• Back up important genealogy files before changing the application or operating system.
• Upgrade a legacy Reunion installation when the developer lists it as incompatible.
• Confirm that converted family files open correctly before removing an older installation or backup.

The key lesson is that Reunion itself is not universally broken on Sonoma; older Reunion releases are the bigger compatibility concern.

Does SABnzbd Work on macOS Sonoma?

Current SABnzbd releases support macOS. The project’s official download page provides a macOS package for Intel and Apple Silicon Macs. Therefore, describing SABnzbd as generally incompatible with Sonoma would be misleading.

If SABnzbd stops functioning correctly after a macOS upgrade, check the installed version first. Folder locations, permissions, network configuration, scripts and third-party components should also be reviewed before blaming Sonoma itself.

Common areas worth checking

• Update SABnzbd to a supported current release.
• Confirm that configured download folders still exist and are writable.
• Check custom post-processing scripts.
• Review network and security settings if remote access stopped working.
• Check SABnzbd logs for the actual error instead of reinstalling blindly.

Users should download SABnzbd from its official source and avoid depending on an old package after a major macOS upgrade.

Why Can SoftRAID Have More Complicated Sonoma Issues?

SoftRAID is more sensitive to operating-system changes because storage functionality depends on close integration with macOS. SoftRAID’s support forum contains a dedicated Sonoma issues section, showing that specific hardware, sleep, driver and OS combinations have generated troubleshooting cases.

At the same time, that does not mean SoftRAID cannot run on Sonoma. SoftRAID support documentation and forum guidance show supported drivers and versions operating with Sonoma, while macOS itself can determine which compatible SoftRAID driver is loaded.

This is one reason storage utilities should be treated differently from a normal productivity app. A problem with a genealogy application may prevent the program from opening, while a storage-driver problem can affect access to important data.

Before updating a SoftRAID Mac

• Back up critical files independently of the RAID array.
• Check the SoftRAID version against the target macOS release.
• Update required SoftRAID components before changing macOS where the vendor recommends it.
• Do not make security or driver changes without understanding their purpose.
• Confirm that all important volumes mount correctly after the update.

Pros and Cons of Updating Older Mac Apps for Sonoma

Pros

• Better compatibility: Current releases are more likely to support modern macOS frameworks and Apple Silicon.
• Improved security: Updating reduces dependence on obsolete components and unsupported application versions.
• Better Apple Silicon support: Native or current builds can avoid compatibility limitations associated with older software.
• Continued developer support: Troubleshooting is easier when the installed release is still maintained.
• Access to bug fixes: Maintenance releases may address issues discovered after major macOS updates.

Cons

• Upgrade costs: Some commercial applications require a paid major-version upgrade.
• Workflow changes: Updated versions may alter interfaces, settings or file formats.
• Plugin or script compatibility: Updating the main application does not guarantee that every third-party extension will continue working.
• Storage-related risk: Driver-level software such as RAID utilities requires more careful planning than an ordinary application update.

Why We Recommend Updating Carefully

For most users, running a developer-supported application release is preferable to keeping an obsolete version solely to preserve an old workflow. Professionals who depend on specialist applications should verify compatibility and maintain a backup before updating macOS rather than upgrading the operating system first and troubleshooting afterward.

How to Fix Mac Apps Struggling on Sonoma

If an application stopped working after installing Sonoma, start with the simplest and safest checks instead of immediately replacing the Mac or modifying system security.

1. Identify the exact app version. Compatibility often differs between major releases of the same application.
2. Check the developer’s documentation. Look specifically for Sonoma or macOS 14 compatibility information.
3. Install maintenance updates. Developers often address macOS compatibility through updated builds.
4. Review permissions. Check file, folder, network and background access when those features are required.
5. Back up important data. This is particularly important before modifying storage utilities or converting application databases.
6. Inspect logs or error messages. The error can distinguish a permission problem from an unsupported component.
7. Consider an alternative only when necessary. Replacing a working application should normally come after checking for a supported release.

Should You Avoid macOS Sonoma Because of Older Apps?

Do not upgrade a mission-critical Mac until the applications you depend on have been checked. The safest decision depends on your software stack rather than Sonoma alone.

If every essential application has a supported version, updating is much less risky. If a critical legacy application has no compatible release, staying temporarily on a supported existing configuration may be more practical until you have an upgrade or migration plan.

For software that cannot be replaced easily, another option may be a controlled legacy environment. Our guide to virtual machines for unsupported Mac apps explains where virtualization can help, although hardware- and driver-dependent applications require additional consideration.
