Can someone help me with a hopefully simple fix? When selecting the box with the image, I usually recale the image with the shift/command key's... it's not working! Would love a fix.
What version of the operating system are you running. (System Preferences > Keyboard > Shortcuts) Apple setts some of the shortcuts at system level and you may have to dissable conflicts in the system setting.
Do you have additional hardware like a drawing tablet? Have you installed anything or upgraded anything since it last was working? Did you restart your computer?
Also check that your hardware is working by opening the Keyboard Viewer application.
I did have a hard drive plugged in. I have a loan MacBook Pro so I did the restart holding shift and it worked!!
Thanks for you post and help.
Try resetting your preferences
I did a restart holding the shift down and it seemed to work! Yay. Thanks
