Run Timelinize

Once you have the Timelinize executable binary, you're ready to run it! (There's no formal install process.)

You may need to ensure the Timelinize binary executable permissions.

We recommend running Timelinize from the terminal or command line so you can view log output if necessary.

Be aware Timelinize will open a web browser tab. (Closing the tab does not stop the application.)

We are not code-signed yet. You may have to override built-in OS protections:


Execute ./timelinize_alpha from the terminal. You can also do it by clicking the binary in your file browser GUI, but we recommend the terminal during alpha versions so you can see any error messages in the logs.


Follow these instructions to run apps from unidentified developers (that's me!). If the error you get says that Timelinize "is damaged," that's a lie: checksums probably match; the real problem is that Apple has placed it in "quarantine" because it was downloaded.

You can either:

  1. Do a two-finger click and select Open, twice (once for the warning, the second time to open it)
  2. Open Terminal and run this command:
    xattr -d ~/Downloads/timelinize_alpha
    (adjust path as needed).

It should finally run, but if you can't open or create a timeline, Apple may be blocking access to your disk. The easiest way around this is to give "Full Disk Access" in System Settings (or at least access to folders you'll be using).


You will get a warning that this software is not signed. Click "More info" and then "Run anyway." If it complains about a virus, it's just because of libheif.js which is embedded to decode HEIC images, and is not a virus.
