Hi forum!

A funny (NOT ) thing happened .... my image size in photoshop doesn't match reality! It's difficult explaining, but if you take a look at the screenshot you'll see what I mean ....

I have a new computer and compared all photoshop settings with the one on my 'old' computer and they are all the same.

Photoshop is in fact right. It always displays 100% as one image pixel represented by one screen pixel. That's the correct way to do it; the very definition of 100% in a raster image editor. But you can set it to View > 200%, and you get the same size if that's what you want.

It is the native Mac OS apps that compensate for the retina display by scaling images up. One image pixel is now represented by no less than four screen pixels. They can do that - they have no obligation to display accurately.

They do this so that images will display at roughly the size people are used to from traditional displays - in order to avoid complaints like yours here.

Photoshop is a professional-grade image editor and has to do it right.

An alternate work around passed along to me by gener7

  1. Quit the app if it's open.
  2. In the Finder, choose Applications folder
  3. In the Applications folder that opens, choose the Adobe Photoshop CC 2018 folder and inside that folder click the Adobe Photoshop CC 2018.app icon so it's highlighted. 
  4. Choose Get Info from the File menu.
  5. Place a checkmark next to "Open in Low Resolution"
    Open in Low Resolution
