Scaling from center anchor point???

To resize and maintain proportion from center point simply do the following. Hold OPTION + click and drag lower right corner point of the layer.

Hi, it works perfectly. Please check if there is any other software taking over your usual Shortcuts.
All my best mate,

I, too, am going insane after updating. Did you ever figure this out?

What is your workflow?  Are you working from the Move tool with Show Transform Controls checked, or using Free Transform directly?  Just to be clear, you are dragging the _corner_ handles together with Opt and Shift, and not the mid handles?

I take it you have checked those Shortcuts are set to the defaults?  A custom set would show in the Edit > Keyboard Shortcuts dropdown.  For instance, I switch to the Essentials workspace when I need to use the defaults.

Do you have any plug-ins that might have stolen the shortcut focus?  Font managers... that sort of thing?

Do you have any other processes running outside Photoshop that might have stolen the shortcut focus?  Screen grabbers for instance.

On Windows Alt transforms from center.  Shift Constrains the transform . For example the Aspect ratio to the current aspect ratio, or to a square or circle.  They can be used together and a corner control point must be use to drag transform being done.

What happens when you do this? It works just like always for me on Windows.
