Before you start: What you need to convert FLAC to ALAC on Mac

FLAC (Free Lossless Audio Codec) and ALAC (Apple Lossless Audio Codec) are both lossless formats, meaning they preserve audio quality without compression loss. FLAC is widely supported across platforms but not natively compatible with Apple devices. ALAC is Apple's preferred lossless format, ensuring seamless playback on Macs, iPhones, and iPads.

To convert FLAC files to ALAC on Mac, you'll need suitable software. Popular free options include XLD (X Lossless Decoder), which supports batch conversion and metadata preservation, and VLC Media Player, which offers basic conversion capabilities. Paid alternatives like dBpoweramp provide user-friendly interfaces and faster conversion with advanced tagging features.

Make sure your Mac runs macOS 10.12 or later for optimal compatibility with these tools. Before conversion, back up your original FLAC files to prevent accidental loss during the process.

Here’s a quick checklist:

Choose and install your converter software (e.g., XLD or dBpoweramp). After installation, you should see the app icon in your Applications folder.
Locate your FLAC files on your Mac. Confirm they play correctly in an audio player.
Create a backup folder for your original FLAC files. Verify the files copied properly by comparing file sizes.
Familiarize yourself with your chosen converter’s interface, especially output format settings. Confirm ALAC is selectable as an output option.

How to convert FLAC to ALAC using iTunes or Music app on Mac

Since FLAC files are not natively supported by the Music app or iTunes, you’ll first need to convert your FLAC files to a compatible format before importing. A common method is to use a free converter to change FLAC into WAV or AIFF, which can then be imported and converted to ALAC within the Music app.

Convert your FLAC files to WAV or AIFF using a third-party tool. Once done, open the Music app on your Mac.
Go to Music > Preferences from the menu bar, then click the Files tab and select Import Settings.
In the import settings window, choose Apple Lossless Encoder from the dropdown menu and click OK. This sets ALAC as the default import format.
Import the converted WAV or AIFF files by dragging them into the Music app or using File > Import. The files will appear in your library.
Select the imported tracks, then go to File > Convert > Create Apple Lossless Version. The Music app will generate ALAC copies of the files.
You’ll see the new ALAC versions appear alongside the originals. Conversion speed varies but typically takes a few seconds per track depending on file size and Mac performance.
After confirming the ALAC files are intact, you can remove the original WAV or AIFF files from your library to save space.

This method uses only native Apple software but requires an initial FLAC to WAV/AIFF step. The resulting ALAC files maintain lossless quality and are fully compatible with Apple devices.

Is FLAC or ALAC better? Understanding the difference

Both FLAC (Free Lossless Audio Codec) and ALAC (Apple Lossless Audio Codec) offer lossless compression, meaning audio quality remains identical to the original source. Neither format compromises sound fidelity, so your listening experience depends more on device compatibility and ecosystem integration than on audio performance.

Compatibility is a key differentiator. ALAC is natively supported across Apple devices and software, including iPhones, iPads, Apple Music, and the Music app on Mac, enabling seamless playback without conversion. FLAC, while widely supported on many platforms and third-party apps, is not natively supported by Apple’s ecosystem, often requiring conversion or special players on Macs and iOS devices.

File size differences between FLAC and ALAC are generally minimal, as both use similar lossless compression techniques. Metadata handling is robust in both formats, though ALAC integrates more smoothly with Apple’s metadata standards, improving tag consistency and album art display in Apple apps.

Feature	FLAC	ALAC
Audio Quality	Lossless (identical to source)	Lossless (identical to source)
Compatibility	Cross-platform; requires third-party apps on Apple devices	Native support on Apple devices and software
File Size	Similar to ALAC, varies by content complexity	Similar to FLAC, varies by content complexity
Metadata Support	Good, wide support but may vary by player	Optimized for Apple metadata standards

For example, if you primarily use Apple devices, ALAC offers hassle-free playback and better integration with the Music app. If you use a variety of platforms including Windows or Android, FLAC provides broad compatibility without conversion.

Troubleshooting common issues when converting FLAC to ALAC on Mac

Conversion errors often stem from corrupted files or incompatible software settings. If you see an error like "File could not be decoded" or "Unsupported format," first verify the FLAC file plays correctly in a media player. If the file is corrupt, try obtaining a fresh copy. Additionally, ensure your conversion tool is updated to the latest version to avoid compatibility issues.

Metadata loss or mismatches can occur if the converter does not fully support tags. Commonly, track titles, artist names, or album art might not transfer properly. To fix this, use a dedicated tag editor like MetaBliss or Kid3 after conversion to manually correct or restore metadata. Before converting, check the metadata fields in your FLAC files and compare them post-conversion to confirm completeness.

DRM protection is rare in FLAC files but can block conversion. If you encounter a "DRM protected file cannot be converted" message, you will need to remove DRM using authorized software or obtain a non-DRM version of the audio. For corrupted FLAC files, tools like FLAC Frontend can attempt repairs, but success is not guaranteed.

Open your FLAC file in a reliable media player to confirm it is not corrupted. Successful playback indicates the file is intact.
Update your conversion software (e.g., XLD or dBpoweramp) to the latest version to ensure compatibility with macOS and FLAC formats.
After conversion, check metadata in the Music app or a tag editor. If data is missing, open the ALAC file in a tag editor and manually enter missing information.
If you receive a DRM error, verify the file source and use appropriate DRM removal tools or acquire a DRM-free version.
If conversion repeatedly fails, try converting the FLAC file to an intermediate format like WAV before converting to ALAC, which can sometimes resolve encoding issues.
