Apple continually releases updates to enhance performance and security, so make a habit of checking for and installing these updates promptly.

Strategic Peripheral Usage

Minimizing the risk of error 21 also involves strategic use of peripherals. Avoid "daisy-chaining" or connecting multiple devices through a single port, as this can lead to power issues and communication errors. When not in use, disconnect external devices to reduce the strain on your Mac’s ports and prevent potential conflicts.

Data Backup and Recovery Planning

While not a prevention method for error 21 specifically, having a robust backup and recovery plan is essential for any Mac user. In the worst-case scenario where an error leads to data loss, having current backups can be a lifesaver. Utilize Time Machine or a cloud backup service to regularly back up your data, reducing the potential impact of any hardware or software issues.

Advanced Diagnostic Tools

Leverage the power of diagnostic tools to catch potential issues before they escalate into errors like badUnitErr. Apple’s built-in diagnostics can help identify hardware problems, even those not immediately apparent. Third-party software tools can also offer deeper insights into the health of your Mac’s system and connected devices.

Professional Maintenance and Advice

For users who rely heavily on their Mac for professional tasks, seeking routine professional maintenance and advice can be invaluable. Tech experts can provide customized advice based on your specific usage patterns and needs, potentially identifying risks you weren’t aware of. They can also perform more thorough hardware checks and maintenance tasks, ensuring your Mac remains in top condition.

By implementing a proactive approach towards maintaining your Mac and any connected peripherals, you can significantly reduce the likelihood of encountering error 21 or badUnitErr. Regular audits, strategic peripheral usage, keeping everything updated, and leveraging both built-in and third-party tools for diagnostics and maintenance are all essential strategies.
