We’ve worked hard to make iA Writer stable and reliable, but sometimes problems occur. Here are some things you can do if you have problems with iA Writer.

Common Fixes

Recover Earlier Document Versions

If some of your changes are lost, a file is overwritten with an outdated version, or you accidentally delete a file, you may still be able to recover an earlier version of your document.


iCloud Drive keeps versions of your documents. With the file open in iA Writer, select the File menu then Revert to… to browse iCloud versions.

In addition, files can be recovered from deletion at Sign in with your Apple ID and then:

Other Cloud Storage

Many cloud storage providers (including Dropbox, Google Drive and OneDrive) preserve multiple versions of your documents for up to 30 days. Please try logging into your cloud storage provider’s web console and searching for Trash or other recovery options.

Specific Issues

iCloud files do not appear in the Library, but I can see them in Finder

The library stores the document listing in an index file. If no documents appear in the Library when they should, this file ought to be rebuilt. To do so, first close iA Writer. Then, open Finder and from the menu choose GoGo To Folder… and copy/type in the following folder path:

~/Library/Containers/pro.writer.mac/Data/Library/Application Support/iA Writer

Within this folder there exists a file named index.db. Move this file to the Trash and then relaunch iA Writer. The index will be rebuilt and your files should show in the Library.

Files don’t open when double-clicked in Finder

Writer should open documents with the extension “.txt” by default. If .txt documents don’t open in Writer when double-clicked, please follow these steps:

  1. Browse to a “.txt” file in Finder
  2. Right-click the file and choose “Get Info” (alternatively highlight the file and issue ⌘I)
  3. Under the section “Opens with:” select iA Writer from the dropdown list
  4. Click the “Change All…” button

All “.txt” files will now open with iA Writer upon a double-click in Finder. You can do the same to switch any other file extension (such as .md) to Writer too.

I cannot save my documents

This is probably caused by the App Store’s copy protection when moving Writer to another computer (or whenever the computer’s MAC address has changed). To fix it just delete the app and reinstall from the App Store’s “Purchased” section.

Why is my CPU usage so high?

Any folders added as locations to the Library must be indexed, which is CPU intensive. As such, we discourage adding extremely large folders such as entire system partitions. If a large folder has been added and you find the app unresponsive, we’d recommend reinstalling iA Writer for Mac in the following way:

  1. If you aren’t using iCloud, backup your files contained in ~/Library/Containers/pro.writer.mac/Data/Documents (should be empty when using iCloud)
  2. Backup any custom templates you’ve added here: ~/Library/Containers/pro.writer.mac/Data/Library/Application Support/iA Writer/Templates
  3. Uninstall iA Writer for Mac with AppCleaner
  4. Restart your computer
  5. Reinstall iA Writer from the App Store
