This cant be true . Redicolous Fools. best idea to change a common interface feeling like that. Is someone Adobe developer using Photoshop at  at all it seems you are just messing up the feeling of everything. Best situation when you have to rush through something on work and you start Photoshop with an awkward feeling like that proportinal transform.

WHY did they change this? Its awful!
I hate to update this software. it always get worst and worst ;*( And why on earth can't we keep the old settings as an option? it make no sense?!

I would be somehow ok with this change if these motherf****** would be consistent with it. God damn not to mention that in illustrator shift has the same behaviour as before, when they want to change it, they should change it atleast through all of their products.

But it's even more frustrating when it doesn't work within the same program, for instance, while working with some smart objects you have to still use shift. Person behind this decision should be fired or atleast change their career. Only moron could approve this, not UX an experienced designer.  I guess this is a result of forced inclusion. God bless CS5.

My muscle memory is really suffering.AdobeSupport​

If it's helpful, I wrote a simple Applescript that toggles the Shift-Proportional/non-proportional thing back and forth.

You need to quit Photoshop, then run it, then restart Photoshop.

It runs a Terminal command line that creates the PSUserConfig.txt file referenced in the official documentation.

Run it again and it deletes the file.

For anyone who doesn't like mucking around with creating preference files and saving them in the right spot, this is as close as we could get to a "push-button" solution.

begin script code

======================

tell application "Finder"

  --grab the path to the PS prefs folder

  set PSprefs to the folder "Adobe Photoshop CC 2019 Settings" of (the path to the preferences folder) as alias

  if exists file "PSUserConfig.txt" of PSprefs then -- if the settings file change is present

  display dialog "The default setting — Proportional Scaling — is turned off." & return & return & "Do you want to turn it on?"

  try -- remove the file

  do shell script "rm ~/Library/Preferences/Adobe\\ Photoshop\\ CC\\ 2019\\ Settings/PSUserConfig.txt"

  on error

  display alert "The text file could not be deleted."

  end try -- try remove

  else -- if the file is not there

  display dialog "The default setting — Proportional Scaling — is turned on." & return & return & "Do you want to turn it off?"

  try -- create the settings file

  do shell script "cd ~/Library/Preferences/Adobe\\ Photoshop\\ CC\\ 2019\\ Settings/; echo TransformProportionalScale 0 >PSUserConfig.txt"

  on error

  display alert "The text file could not be created."

  end try -- try create

  end if -- exists

end tell -- Finder

========================

end script code

THIS IS DRIVING ME CRAZY!!!!!!!!

Hey, while we're at it, let's convolute some more functions, Adobe. Who the heck do they have working on this stuff?

As inane a concept as Apple making you plug a first gen "pencil" into the Lightning port on ipad Pro. Nothing pro about that stupid concept... then they abandon 1st gen owners of their product by not making the next iteration backward compatible. I'm so sick of these bloated corps taking advantage of designers who spend good money and have remained loyal over the decades.

More and more I'm seeing independent software devs offering Open Source design tools. May have to go that route.

It's as if Adobe just doesn't care what designers / illustrators / users think about their products as they continue to make poor UX choices.

BIGGEST WTF EVAR!
none of the other adobe products do this, so good luck trying to retrain your fingers.
can't even believe the depths of egotistical idiocy necessary to dump this on us.

Just another day ruined by adobe 2019. put it off as long as I could, and knew BS was coming. This plus changing undo commands and taking all the tools out of the toolbar are the one that have thrown me off all morning. Why? I wonder if has anything to do with these tools all matching Power Point functions and commands now. I thought adobe was to keep the pitch deck posers out!

Thank you for the fix. This is the worst bit of UI work I have ever seen, absolutely amazed this passed. Just going to echo others in the hope that someone at Adobe reads this.
