Is the following copies from https://www.epaddproject.org/using-epadd/download-and-install still valid?

Operating Systems: Windows 7 SP1 / 11, Mac OS X 10.12 / 10.13, Ubuntu 16.04
Memory: 8 GB RAM (4 GB RAM allocated to the application by default)
Browsers: Chrome 61 or later, Firefox 55 or later
Java: Java Runtime Environment 11 or later required.

commented

Yes, this should still be valid.

What about macOS 11/12/13/14? One more question: If I have >8GB RAM, will ePADD take >4GB?

commented

We haven't tested on different versions of macOS yet, but they should work fine. I shall do some testing.

ePADD always takes 4GB RAM by default. You can allocate more memory by launching ePADD from the command line like this:

java -Xmx#g -jar epadd-standalone.jar

replacing # with the amount of RAM in gigabytes (GB) you want to assign. For example, to allocate 6 GB, use

java -Xmx6g -jar epadd-standalone.jar

Thanks.

I used java -Xmx8g -jar epadd-standalone.jar in a terminal. ePADD didn't launch. Here are the last few lines in the terminal:

Does it work without the memory specification just using
java -jar epadd-standalone.jar?

commented

No, it doesn't work. I checked the Java in the machine and get the follwoing:

(base) pchan3@Peter-MacBook-Pro ~ % java -version
java version "1.8.0_391"
Java(TM) SE Runtime Environment (build 1.8.0_391-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.391-b13, mixed mode)

The dmg file comes bundled with a version of Java, whereas when starting ePADD from the command line, the Java version installed on your machine is used. It seems that is Java 8 and the current version of ePADD needs at least Java 11. Could you please install a newer Java version, for example from here: https://www.oracle.com/uk/java/technologies/downloads/#jdk17-mac?

commented

Great!! Thank you so much. It works now.
