Apple will make macOS Big Sur – its latest and greatest release of macOS – available sometime today, Thursday, November 12.
Although Apple hasn’t shared an exact time that it’ll enable downloads of its first Apple Silicon-capable version of macOS, it’s possible to make an educated guess, based on past macOS releases.
As noted by MacRumors, Apple lists a release date of November 12 on its Indian site, while its Thai site lists a November 13 release date. Those two countries are 90 minutes apart by time zones, which suggests a release window of sometime between 9:00 a.m. and 10:30 a.m. Pacific Time. Past releases also narrow it down a bit, meaning the most likely release time in that window would be 10:00 a.m. Pacific.
It’s worth noting, however, that major macOS releases over the past several years have typically come closer to 11:00 a.m. Pacific Time, so it’s certainly possible it could be a bit later than our prediction of 10:00 a.m.
