TmpDisk 2.3.0

⚠️ Existing users must update manually (one time)

This release rotates the Sparkle signing key — the previous key was lost, so older versions cannot auto-update to 2.3.0 and the in-app updater will not offer it. Please download TmpDisk.dmg below and replace your current copy. Future updates will auto-update normally.

What's new

• Standalone CLI — tmpdisk works on its own without the GUI running.
• Folder sync — copy a folder into a RAM disk on creation, save changes back, sync on an interval, and choose save-on-eject behaviour. (closes #57)
• Expanded CLI options — --autocreate, --indexed, --warn, --noexec, --hidden, --autoeject and sync flags. (closes #56)
• macOS 10.13 High Sierra support.
• Auto-eject on quit option for volumes.
• Japanese translation. (#53)
• noexec / hidden volume handling improvements.

Fixes

• Security: volume names are now strictly validated, preventing shell-injection into the privileged (root) helper.
• CLI eject now honours warn-on-eject and prompts when a volume still has files (--force to skip). (closes #58)

Minimum macOS: 10.13. Notarized; Apple Silicon + Intel.

v2.1.0

What's Changed

• Adds background helper to allow tmpfs TmpDisks to be created without prompting for the system account password.

Full Changelog: v2.0.7...v2.1.0

v2.1.0-beta

2.1.0 alpha adds the ability to install a background helper that has root permissions and can run TmpFS creation without prompting for a password.
Right now the communication between the two services is somewhat secure but I imagine I will need to sure up the interface on the TmpDiskCreator to check the incoming commands more thoroughly to ensure that only mountfs and other calls are valid.

This has been fairly well battle tested by a few people over the past few months but if you'd like to help the final stretch of testing please reach out at t@imothee.com or at @imthie on threads or https://macaw.social/@imothee

Update 7/21/24

Fixes issue with code signed helper not always being valid through XPC. This means the tmpdisk creation should always work when using the helper now. Fixed the way XPC calls are made so there's no hanging creation threads or errors when uninstalling the helper.
