Background:
The problem occurs:
- When connected through AFP protocol to a network volume.
- If File Vault is turned on.
- If the file is saved with the apostrophe (') character inside a folder named with this character, the Save button becomes disabled after changes two or three times.
Solution:
- Connect to the network volume via the SMB protocol
- The problem only occurs with the (') character. Therefore, do not use this character when naming your projects.
