Following the release of macOS Sierra last month, the latest operating system has caused some compatibility and stability issues with Adobe Photoshop and Microsoft Office 2016 for Mac that both companies are working to resolve.
A growing number of users on Adobe's support community claim that Photoshop CC crashes when attempting to print projects after updating to macOS Sierra. Doug Thomson, for example, is unable to print to his Epson 7890, while some other Epson and Canon printer models appear to be affected.
Installed macOS Sierra and now Photoshop 15.5.1 crashes when attempting to print. Print dialogue opens and settings can be modified, but when attempting to print Photoshop crashes perhaps 9 out of 10 attempts. Most frustrating. I'm printing to an Epson 7890, but I have seen the same issue cited for Canon. Adobe support told me that Photoshop has not been tested on Sierra, but in reality Adobe has had Sierra for months and have even published known issues. I pay a ton of money for this thing to work and this nonsense from support is very annoying.
Adobe has since acknowledged the issue in a support document, noting that Photoshop CC version 2015.5 or earlier may crash while printing to some printers from Macs running macOS Sierra. Adobe said its engineers are working on a solution for a future update to Photoshop CC, as echoed by Adobe product manager Pete Green.
Separately, Microsoft has acknowledged that Office 2016 for Mac closes unexpectedly, or crashes, for some macOS Sierra users. The company's engineers are working with Apple to investigate and resolve the issue.
MacRumors reader Adam C. emailed us about his problems on macOS Sierra:
Office for Mac is causing me heaps of trouble. Computer hangs, and I can't even force quit the applications. Have to rudely switch off computer and restart.
Until a fix is released, a new support document suggests turning off "Auto Proxy Discovery" or "Automatic Proxy Configuration" as a possible workaround, if allowed by your personal or organization's network configuration.
