Fifth, Common FAQs

We have compiled the following Q&A to help address common issues.

Q1: Why can’t I open the file after downloading, and it says “file damaged”?

A: This is macOS’s security mechanism blocking it. Refer to the steps above for “Resolving the ‘Unable to Verify Developer’ issue” in the “System Settings” -> “Privacy & Security” to manually allow opening. If still not working, try re-downloading the file, as it might have been damaged during the download process.

Q2: Is this version in Chinese?

A: Yes. The version provided on this page is already pre-installed with a Simplified Chinese language pack. After installation, the software will automatically match the system language, or you can switch to Simplified Chinese in the software’s “Preferences” -> “Language”.

Q3: Where can I find the activation code? How do I activate?

A: The activation code is usually included in the downloaded file, named “activation code.txt” or similar. Open it and copy the sequence number to the software’s activation window. If you can’t find it, check if the downloaded zip file was fully decompressed.
