The 1.3.13 version is in my applications folder. it is the audacity headphones logo and to the right of the logo it says Audacity.app.
Should I just drag that to the trash?
also the new Audacity is in a folder in applications and when I open the folder I see several files plus the one that looks like the one I just described - the icon plus the words Audacity.app.
Is that fine like that or do I need to drag the Audacity.app out of it’s folder so it is directly in my applications folder.
The 1.3.13 Audacity.app should have been in its own Audacity folder with its Plug-ins and other files and folders. If so, drag that entire Audacity folder to the Trash. If you now only have the app, then yes, drag it to the Trash.
The 2.0.5 Audacity.app must stay inside its “Audacity” folder in /Applications, otherwise it may not work properly. Then you have to eject the DMG and run the 2.0.5 app from its folder in /Applications.
In case there are any problems you can delete everything to do with Audacity from /Applications then mount the DMG again and just drag the “Audacity” folder from the DMG to /Applications again. Then eject the DMG and run the 2.0.5 app from its folder in /Applications.
