Hardware details...
Two different Macs...
Machine 1
Mac Pro 5,1 with NVIDIA GTX980
macOS 10.12.5 Sierra
Machine 2
iMac 12,2 with AMD Radeon HD 6970M 2048 MB
macOS 10.12.5 Sierra
Neither mac will start Premiere Pro after updating to 10.12.5 and the latest release of PrPro CC 2017 today. Both machines will successfully launch all other CC applications including older versions of Premiere Pro CC and CC 2015, both of which launch and create new projects with no issues under 10.12.5.
Deleting permissions has not helped. Starting with option or SHIFT-option has not helped. The application on both machines shows the splash screen for about 1 second then it simply disappears. The only cryptic entry in the system log is:
Adobe Premiere Pro CC 2017[1774]: AdobeCrashReporterInitialize: executionTime = 0.004176 seconds
com.apple.xpc.launchd[1] (com.adobe.PremierePro.CC11.11852[1757]): Service exited with abnormal code: 1
Unfortunately the Adobe Crash Reporter doesn't run so I don't get a more detailed report.
Logic would dictate that there seems to be an issue with Premiere Pro CC 2017 specifically and 10.12.5.
Any thoughts?
