Steps To Reproduce:	1) Create some audio, File > Export Audio... , 2) open Custom FFmpeg export, select a format and codec pair, OK. 3) Save. 4) A dialog appears "NoOverwritePrompt<random characters> already exists. Do you want to replace it?". 5) At this point the unwanted file that is said to already exist is created. 6) If you Cancel the replacement, the newly created file is left behind. 7) If you choose to Replace, the newly created file is deleted and the file is exported correctly. 8) Change step 1 to choose (external program) instead. Browse to a suitable binary that Audacity can use (FFmpeg is easiest to find). Then repeat Steps 2 to 5 with the same result.
Release Note:	GROUP: Exports * (Mac OS X) '''When exporting using (external program) using any encoder, or using "Custom FFmpeg Export", you must agree to create and replace an unwanted "NoOverwritePrompt" file before you can export.''' The exported audio file is correct.

Description Gale Andrews 2015-09-06 21:29:36 UTC

Regression on 2.1.1. Occurs on Mavericks and Yosemite.

Comment 1 Gale Andrews 2017-01-11 00:02:46 UTC

Occurs on Sierra too. Occurs in exactly the same way with (external program) too, as well as "Custom FFmpeg Export".

Release Note and bug title updated.

Comment 2 Peter Sampson 2019-06-11 09:20:54 UTC

And occurs with 2.3.3 alpha jc001 on Mojave macOS 10.14.5 too

Comment 4 Peter Sampson 2020-03-24 07:32:22 UTC

(In reply to Leland Lucius from comment #3)
Tested on macOS 10.15.3 with Audacity 2.4.0 b1226cc

This now exports properly without the error message at Step 4.

The exported file can be played or re-imported fine.


I also tested Audacity 2.4.0 b1226cc on W10 to ensure that it works there too
