Developers can download the ‌macOS Tahoe‌ 26.4 update by opening up the System Settings app, selecting the General category, and then choosing Software Update. Beta Updates will need to be enabled, and a free developer account is required.

‌macOS Tahoe‌ 26.4 could introduce some new Siri features, though at least some of the capabilities that we were expecting have been delayed. The update is also expected to introduce new emoji characters.

The beta is available to developers right now, but a public beta is expected in the next week or two.

Same here! :-( My external drives work fine on another Mac not running this beta, of course.
maybe disable fsck_hfs before attaching drives?


* Kill the Process (Temporary Solution): If fsck_hfs is blocking access to a drive, use Activity Monitor or the Terminal command sudo killall fsck_hfs.
* Disable SIP and Rename fsck_hfs (System-wide):
[LIST=1]
* Boot into Recovery Mode (Command+R) and run csrutil disable in Terminal to disable System Integrity Protection.
* Restart the system.
* Rename the utility: sudo mv /sbin/fsck_hfs /sbin/fsck_hfs.disabled.

* Use fsck_hfs -n (No Repair): Run fsck_hfs with the -n flag, which forces it to never attempt to repair any damage found

Checked file vault settings, but they were turned off, I thought Tahoe by default enabled encryption of home folder? :rolleyes:
I don't think Apple has ever enabled FileVault by default, since the user needs to know if their drive is encrypted, and select settings that work for them. A full setup requires the user to establish a "backup" unlock method in case you forget your macOS password. You can choose to use your Apple ID to reset your Mac's password to unlock your drive, or use a local recovery key (a long string of random letters and numbers).

Also, FileVault has encrypted the entire drive for years. You might be remembering "Legacy FileVault," which encrypted only the Home folder, but Apple moved away from that years ago (around Mac OS X Lion) since it was prone to errors and didn't protect system files or temporary data stored outside the Home folder. Modern FileVault uses XTS-AES-128 encryption with a 256-bit key to secure the entire volume.
