Just relaying the information and giving people a heads up:
64-bit deployment is coming soon! Here’s the target schedule for each distribution channel: Insiders Fast -> 64bit release on 6/29, using main 160628. Insiders Slow -> 64bit release on 7/5, using main_rel ~160702 (June fork). Production -> 64bit release on 8/16, using main_rel ~160808 (July fork) These dates are subject to change if we find blocking issues. One major point of caution: external plugins like EndNote are not currently 64-bit and will not work until they are released for 64-bit. We are working closely with EndNote; they are aware of the dates and are close to done with their update themselves. EndNote may not have a release done in time for the 6/29 or 7/5 dates, but those are insider drops that shouldn’t be deployed widely. We do expect EndNote to have a 64-bit release in time for the wide production release in August.
This is from the #microsoft-office Slack channel http://macadmins.org and coming straight from Microsoft.
