Since upgrading to macos High Sierra, my Photos.app
's editing functions have been troublesome. Features such as Retouch
simply do not work, and I'm unable to access advanced options, such as the Shadows
slider commonly found under the "Light" adjustment.
OSXDaily put out a troubleshooting guide for HS apps today which included a "Create a new account to test app" suggestion, which I did. On the new test account, Photos.app's Edit
features work as they're supposed to; Having not seen it work properly before, I did not know what to expect, nor what was missing prior.
On my original login, Photos.app's Edit screen doesn't show the pull-down arrows that should be to the left of Options
. Without that pull-down, most features are impossible to access. I've tried re-sizing the window's internal and external dimensions, changing screen resolutions, and changing the scroll-bar behaviour.
I blew away the ~/Library/Preferences/Photos.plist files, to no avail. I'm not sure what other configuration files could be interfering with the Photos.app editing UI.
I'm not sure how to proceed without clobbering my current login account.
