They're restless.

Users of office home and business 2010 who upgraded to Apple's OS X 10.11, aka El Capitan, have grown to be increasingly annoyed by repeated crashes from the Office applications, angrily denouncing Microsoft, and also to a smaller extent, Apple, on the former's support forum.

"It's called Office ??2016' because that's the expected date it ??might' work, although much more 2016 is not clear, assuming we are while using Gregorian calendar!" wrote someone identified only as "bluedolphin" in a Tuesday message on the longest thread dedicated to the crash issue.

As of late Wednesday, that thread have been viewed more than 39,000 times and contained nearly 400 messages, both high numbers for the Office for Mac support forums.

Most focused their ire on Microsoft.

"Light a fireplace under somebody's a to get a fix out, or at best a work-around," urged "MS Patsy" in a Monday answer a buy office 2010 professional program manager who had posted on the thread a week ago. "Now you realize why I switched to all Mac products. Windows and Outlook would be the only remnants of Microsoft JUNK that I'm left with."

But some expanded their exasperation to incorporate Apple.

"How could it be remotely feasible that neither Microsoft (mostly at blame) or Apple (ignorance is not great customer support) had any proactive communication not to DOWNLOAD EL CAPITAN?" asked a commenter labeled "cxr341" on Tuesday. "It would have been a simple correspondence: ??Hey, we have seen you use our new Office 2016 on Mac, there is a big OS X update coming, give us a bit of time until you download it.' No harm, no foul."

The bulk of those reporting problems with Office for Mac 2016 began seeing the applications crash a week ago after they upgraded to OS X 10.11, aka El Capitan. The problem dates back beyond that, however, with complaints first appearing July 10, only one day after office home and student for 2pc launched the production build of Office for Mac 2016 and Apple delivered its first public beta of El Capitan.
