When I use the MacOS downloader it only downloads the .dmg file and no .app file, am I doing something wrong?!

This is correct. If you double click the .dmg on a Mac, then it should open a Finder window showing the .app folder that can then be dragged onto your Application folder.

When doing so on macOS Monterey I get an error message: “DataWarrior” cannot be opened because the developer cannot be verified. macOS cannot verify that this app is free from malware." Please advice. Thank you.

Ad hoc bypass for a weekend: See if fetching a live iso of a Linux distribution (e.g., Xubuntu) allows you to start the computer. While booting, you have an option for "try without installation", so there will be no accidental permanent changes to the computer. All you are going to see is because the OS you access resides in the (non permanent) working memory, including a web browser.

+ fetch the installer for Linux from the download page[1] (ca. 152 MB by today). For subsequent ease, move the installer archive to the desktop by drag with the mouse.

+ the program menu should have an entry like "terminal (emulator)". Enter the directory where the installer is located, e.g., by 
cd ~/Desktop
+ from the terminal, decompress the archive by the command 
tar -xzf datawarrior550.tar_gz
This is going to create a new folder datawarrior_linux, which you shall enter (
cd datawarrior_enter
+ still on the terminal, issue then the commands 
chmod 755 install.sh
, and after it's completion, run 
bash ./install.sh
If the terminal doesn't notify you an error, your are ready. Speaking for Xubuntu, DataWarrior then is among the programs in section "Office". Try if you can open DataWarrior.

From now on, every action by DataWarrior is constrained by the available remaining RAM, but e.g., the generation of a (small) library of random molecules and the assignment of SMILES etc. works well enough (just tested in an image of Xubuntu 20.04.2 LTS, focal, running from a USB thumbdrive). To save the work, either deposit the files on a second thumb drive connected simultaneously to the computer, or try intentional access of the hard disc of the computer. The later may fail if the underlying partition is e.g., encrypted.

In the longer run, cohabitation of Linux with an other already installed operating system might be an option, known as dual boot (example tutorial,[2]). This uses a separate partition of the hard disk/permanent memory of the computer.

Good luck,

Norwid

I cannot check on Monterey, but on older MacOS version could do one of these:

- Open Finder.
- Locate the app you’re trying to open.
- Option+Click the app.
- Select Open.
- Click Open.
- The app should be saved as an exception in your security settings, allowing you to open it in the future.
Bypass the block in your Security & Privacy settings. If the previous method didn’t work, you can go into
your Security & Privacy settings and do it manually.

Or / And:

- Open the Apple menu, and click System Preferences.
- Click Security & Privacy.
- Click the General tab.
- Click the lock in the lower right corner of the window.
- Enter your username and password when prompted, and click Unlock.
- Click the App Store and Identified Developers radial button.
- Look for “DataWarrior was blocked from opening because it is not from an identified developer” and click
Open Anyway. (In older versions of macOS, you could click Anywhere and then click Allow From Anywhere.Wink
- Try rerunning the app.

There are also report that you should use Safari to download an app, because other browsers may cause a problem. I don't know, whether that can be an issue for the DataWarrior.dmg file.
