PKHEX WORKS ON CATALINA IF YOU USE CROSSOVER 19.0 and follow @pkman99 steps
I followed the steps and it worked perfectly.
Here's a detailed breakdown (taken directly from his comment a few pages ago). There are 3 main parts.
First part:
1. Open Crossover, click install a windows application towards the bottom
2. On the first page Select An Application To Install, TYPE "PKHEX" and click "unlisted application" on the dropdown
3. On Select Installer select the .exe file NOT the zip, you have to unzip beforehand
4. On Select Bottle select "New Windows 7 Bottle" not 64 bit
5. Install
6. After that's done go to the folder where it's installed. If you don't know search "PKHEX" in Finder and click into the folder
7. There will be a "drive_c" blue folder, click into that and move move the PkHeX.exe file into the "drive_c" folder
Second part, you're installing a Microsoft .NET framework using crossover
1. Using Crossover again, click install a windows application (towards the bottom)
2. On the first page Select An Application To Install, TYPE "Microsoft .NET" and scroll down until you see 4.7, which is the most recent one
3. On Select Bottle select "PKHEX" or whatever you named your file on the First part, step 2
4. Click through the prompts as will take a while, it will install everything from 1.0 - 4.7 since you don't have any of those programs. Do not restart until you've installed 4.7
5. Restart Mac after everything is done
Third part:
1. After you restarted open Crossover
2. On the first page there should be a "Run Command" button, click it
3. Where it says Command click Browse, this should you directly to the "open_c" folder from earlier, where you have your PkHeX.exe file.
4. Select the PkHeX.exe file, and hit RUN
5. If you select save as launcher then it'll create a shortcut on the crossover app
That's it, should work from there.
Edit: updated steps
