Revisiting ZFS for Mac

a year ago

Apple planned to port ZFS to Mac OS X in 2007, but Sun CEO Jonathan Schwartz prematurely announced it, disrupting Apple's plans.
ZFS was initially included in a developer version of Leopard as read-only, but support was later dropped by the time Snow Leopard was released.
Speculation that Time Machine used ZFS snapshots was incorrect; Apple later implemented it using APFS snapshots.
ZFS had compatibility issues with HFS+, such as limited Unicode filename support and lack of case-insensitivity, which Apple could have addressed.
Apple chose to develop APFS instead of modifying ZFS, despite initial assumptions that ZFS would be adapted.
APFS had its own issues, including delayed documentation, poor performance on spinning hard drives, and lack of tools for users.
ZFS offered features like data integrity and transparent compression, which APFS lacks, leading to continued file corruption issues.
APFS's memory requirements might have been a concern for iOS, though iPhones now have more RAM, potentially making ZFS viable.
