According to this, https://roaringapps.com/app/photoshop-cs5 it works through MacOS Sierra (10.12). And appears to partially work under High Sierra (10.13) but users report that it does not work properly under Mojave (10.14) or later version of MacOS.

10.6? It's going to be an old version that's for sure.
