Hi, I have been using external NVMe disk since March 2025 with my Mac M1 1TB until recently couple of days agao I updated Mac OS to Tahoe from Sequpoia 15.6. Now Mac OS Tahoe is disconnecting my NVMe automatically saying please eject the disc before disconnecting and suddenly after an hour it reconnects. Right now I have reinstall Mac OS Sequoia and My external NVMe disk is working again. This post is for Mac OS developers to check for APFS drivers on Mac Tahoe as they are messing up with external NVMe SSD. I dont know about others brand of NVMe I am using Transcend inclosure with transcend NVMe 2TB SSD hard disk.

Kindly please check as its not NVMe issue its and OS issue. If it was NVMe issue my SSD should also not work with Sequoia but as it is working with Sequoia so it has to be something with Tahoe OS.

Kindly review your code about APFS drivers or thunderbold USB C drivers or may be something else linked to APFS file system.

I hope this post reaches you and you guys can consider it as help ful.

Kind regards

These are the Developer Forums, where third-party developers of apps for Apple's platforms ask each other for hints and tips on coding.

These forums aren't a direct line to Apple's developers.

If you have an issue, you can raise a bug at: https://feedbackassistant.apple.com/ If you do so, please provide the full model number for your NVMe drive, and the exact versions of macOS that you tried. They will be needed.
