Comment récupérer des scripts photoshop sur mon ancien Macbook ?

I do not do French and there may be some communication problem with Web language translation.   In there is a big difference in Photoshop meaning between Actions and Scripts.   Action are Recorded and Photoshop steps the have fixed settings and no logic just step step step.  Scripts are computer programs  you design and implement  with a script program language to logically perform Photoshop steps.   You seen the be referring to Actions.  You are showing the Actions Palette.  If you have edited and added Action and Action sets and did not  Saved the Action sets into ActionSetName.ATN files the only place these modifications and addition are recorded is in our User ID Photoshop Preferences  folder.  in "Actions Palette.psp" Which You have found and recovered.  If you are still missing  Action  you have lost them if you did not save *.atn files.    Apple seems to have something call the Time Machine  see if thet a history of  files for "Actions Palette.psp"  Save the Action Sets you have recovered into *.ATN files  for safekeeping then keep restoring other older 

"Actions Palette.psp" version see if any have your missing Actions.

Any time you make modifications to the Action Palette you should highlight the Action Set that you have modified or Added and use the Action Palette Fly-out menu item "Save Action" the save the Action Set into and *.atn file on you system for safe keeping.  Should your Photoshop preferences be reset you will loose all your Actions.  Set up Folders on your Mac to saver your Addition to Photoshop.  Use folders you setup and maintain not folder Adobe creates.  So you know where they are and you can use then in all versions of Photoshop you install
