3 Fixes to Logic Pro Scanning Audio Units Stuck

With seamless integration, the digital logic workstation has brought creativity and innovations with new dimensions for musicians. The stunning relationship between the audio workstation and the plugins is the heart of blending the Audio to discover something new.

Moreover, the software scanning process stops when “audio unit stuck” appears, limiting the possibilities. And this frustrating scanning process can be overcome by troubleshooting or removing the corrupted plugins. So, from corrupted plugins to compatibility, this guide will help create and solve the issues when audio units get stuck. 

Why is Logic Pro scanning audio unit stuck?

When Apple works with third-party plugins for a better user experience, it halts the overall creativity and disrupts the smooth workflow. The logic pro gets stuck with an error popup message, from compatibility issues to corrupted plugins or incomplete popup installations.

Besides the built-in audio or instrument plugins, Logic uses third-party plugins that must first be installed on your computer. The audio units must be completely installed and work properly to avoid errors.

The issue arises during the scanning of plugins because it’s hard to analyze third-party audio plugins, and it affects the overall performance. So, hereunder enlisted the prominent reasons why audio units hang during scanning:

Corrupted Plugins Caches:

The cache stores information about frequently used data for easy accessibility and swiftly opening audio units. And when there’s a corrupted cache file, it will get stuck during the scanning or constantly rescan the plugins whenever you open the workstation.

Improper Plugin Installations:

• When installing third-party plugins, it’s essential to analyze their compatibility, but installation errors happen due to the following reasons:
• Inadequate permissions or documentation can lead to incomplete installations that hinder the proper scanning process.
• When installing the plugins from unidentified sources.
• Using unstable internet connectivity that leads to incomplete structures.

Plugin Compatibility issues:

Plugins — be they VSTs or auto tuners like Antares for your recorded vocals using studio-grade microphones like the Hollyland Lark M1— play a vital role in polishing your overall music. However, it is important to determine whether your chosen plugin is supported by Logic Pro.

• If you are trying to install the plugins incompatible with the current logic version, it will be stuck and unable to read for further process.
• The plugins you are trying to install need to be updated, and an error message will pop up whenever trying to run the plugin.

These prominent reasons will affect audio unit scanning and hinder productivity or creativity. After analyzing the core issue, it becomes easy to implement the solutions.

So, if you’re a professional or starting, this step-by-step guide will help in smooth music production by removing the halting audio scanning process.

Removing the Corrupted Plugins

When Logic hangs on the window “updating information about Audio Unit plugins,” it will keep scanning the audio units. Logic scans the plugins for the first time, and if there are many third-party plugins, it might take a few minutes to complete the scan.

So, follow the methods to identify and remove the corrupted plugins:

Method- 1

• Quit the Logic and click on the “Finder menu” from the bottom left corner.
• Open the Finder, click on “Go to Folder,” and tap to navigate to the components folder Macintosh HD > Library > Audio > Plugins> Components.
• Furthermore, after the plugins, you must select VST, VST3, and Components because it’s the storage house of corrupted plugins.
• And if there’s any problem with any plugin, click to remove it and check if the logic opens afterward.
• Create a “separate desktop folder” and copy all the plugins from the components to this folder.

• After that, delete the components and ensure to clear the plugins from the trash.
• Then open the Logic Pro, and it will open without any frustration.

Method- 2

• Logic AU safe mode is the best choice when plugins fail the validation scan and cannot be viewed in the logic pro.
• You can quickly analyze which plugins are causing the problem from the Logic AU Safe Mode.
• Then, uninstall or update the problem-causing plugins and try launching the workstation.
• It will smoothly open after the first-time scanning.

Method- 3

• First, click on the Logic while pressing down the “Ctrl button.”
• Press on the “No” when it asks if you want to launch the “Core Audio.”
• Then turn off the audio preferences from the next window and apply the changes.
• After that, remove the corrupted plugins and open the Logic Pro without hesitation.

After that, you have to move the copied plugins to the components folder and check for the plugin which causes the workstation to stop working. Then remove the corrupted plugin, and it will start working without hesitation.

Clearing the Cache Files

During the scanning, Logic Pro creates cache memory to avoid repeating the scanning process. Over time, the cache becomes corrupted, leading to corrupted files and prolonged scanning time. So, to clear this issue, you have to remove the files by the following method:

• Right-click on logic pro and quit the Logic workstation.
• Then click to open the “Finder” and tap “Go.”
• Click and open the “Library” from the popup menu.
• Then delete the audio unit cache files (com.apple.audio units. cache) that are located in the /Users/ Library/ Caches/ AudioUnitCache/

• Then clear the cache files after right-clicking, and it will remove the corrupted files.
• After that, restart your computer, re-launch the Logic, and the plugins will work smoothly. It’s the most critical process because it will refresh the logic pro and prepare for fresh operations.

If the cache folder shows 0kb, then removing the folder will clear the existing issues. Also, eliminating the components before the cache or after the verification process is essential, and it will get stuck on the window again.

Sometimes, there are two cache files, so remove both folders and delete them from the trash. It will rewrite the plugin caches without any interference for a seamless experience.

Compatible Audio Units Plugins

Checking compatibility is essential if you use many third-party plugins because it will hinder the overall work performance. Apple’s Logic 10.5.1 version can scan plugins within a few minutes because of enhanced performance optimization, but the previous ones take longer.

Go to the plugin manager and check the plugin status from the compatibility column.

If “failed validation appears,” then ensure that it has been authorized by the manufacturer and then rescan for its compatibility or quality.

Also, if there’s still an incompatible plugin, check for updates or notifications and suggest removing it. Logic Pro doesn’t support 32-bit plugins, so it’s recommended to remove and reinstall 64-bit compatible plugins.

Ensuring that the plugins seamlessly align with Logic requirements or manufacturers’ authorization is essential. And it’s better to reinstall them to avoid the frustration of the scanning process.

Conclusion

Logic Pro elevated the seamless music experience with its multitrack recording software that brings excellence to creativity. Yet, this curiosity fades away when it hangs during the scanning halting the overall workflow. However, implementing the abovementioned methods of clearing components or cache files will start working smoothly.

It also chooses compatible plugins to bring a profound virtual experience that will resonate with excellence and clarity. So, plugins are a significant setback when scanning hangs but resolving it brings endless possibilities.
