The incompatibilities with macOS 27 Golden Gate have been solved.
Daylight-saving time information for Alberta, Manitoba, and the Northwest Territories in Canada and for Morocco and Western Sahara has been updated. The two Canadian provinces and the territory abolished the switch to standard time and will observe daylight-saving time all year round. From now on, Alberta and the Northwest Territories will stay on Mountain Daylight Time or, equivalently, Central Standard Time (UTC-6), while Manitoba will stay on Central Daylight Time or, equivalently, Eastern Standard Time (UTC-5). Morocco and Western Sahara canceled daylight-saving time and moved to GMT at 2:00 AM on September 20, 2026.
Minimum required system version is now macOS 12.
