OSX 10.12.3  That in itself is a red flag. Older software that ran under 10.6 is going to have difficulties with 10.12

Simplest idea would be a restart of your Mac. Many times that clears up problems.

Next is to look at third party plugins and fonts and resetting your Preferences if this problem persists.

This blog will explain this in detail.

Officially, Photoshop CS5 isn't supposed to run on Sierra - but there's a thread here, in which an official response with multiple steps and problems were addressed:
Photoshop CS6 and earlier: Compatible with MacOS Sierra 10.12? | Photoshop Family Customer Community
