Users are once again facing issues with Time Machine backups on macOS Tahoe. The problem stems from Apple's changes to SMB defaults, specifically the requirement for signed connections, which older NAS devices struggle to handle without specific configuration. This has resulted in broken backups, causing data restoration failures for users.

To address the issue, users need to adjust settings on both their Macs and NAS devices. Adjusting the `nsmb.conf` file on the Mac is one fix but it's not ideal. On the NAS, SMB settings must be updated. This involves enabling SMB3, opportunistic locking, and durable handles, while disabling server signing and transport encryption.

Frustrated by these recurring problems, the author is exploring alternative backup solutions. They are leaning towards using a Docker image called `mbentley/timemachine`, which offers more control over the SMB implementation. This would bypass reliance on Synology's software. They also express frustration with other recurring macOS bugs.

Ultimately, the situation underscores the need for Apple to improve its communication regarding changes and prioritize the reliability of core features like Time Machine. Users are seeking more stable, transparent solutions for their essential data backups, especially as storage needs grow.
