jfg17 14 Posted May 23, 2020 Report Share Posted May 23, 2020 Does HD work on Apple computers? If yes, what are the Mac requirements, and what special steps might I need to take to get it set up? Many thx. Quote Link to post Share on other sites
Simon 1,045 Posted May 23, 2020 Report Share Posted May 23, 2020 It's developed on a Mac, so I'd say that it runs just fine on them 😉 The requirements are the same as for all other systems: a full/functioning installation of the Java JRE (version 6 or better, but that's kind of a given these days).

jfg17 14 Posted May 23, 2020 Author Report Share Posted May 23, 2020 TY - I have the latest version (Version 8 Update 251), so I'll assume I'm all set! Simon 1 Quote Link to post Share on other sites
unclevlad 813 Posted May 30, 2020 Report Share Posted May 30, 2020 The latest version is, I believe, 13. Not sure the last update number. But if you're not coding in Java? It's not likely you need to go past 8...or at least not often. 10, perhaps, as there were some significant language chances in 9 and 10, but I suspect it's not common for general-use apps.

Korren9 0 Posted June 15, 2020 Report Share Posted June 15, 2020 I downloaded the ZIP (after paying for it!) and Unzipped it and opened the .JAR file (on Mac AirBook) and it told me I need the JDK (Java Developers' Kit) so I downloaded and installed THAT, now when I open the .JAR file absolutely nothing happens. I mean, it makes the little animation like it's starting a program, but nothing is showing up, anywhere. {sigh} Quote Link to post Share on other sites

I think I deleted every bit of the installed HD files, restarted and reinstalled and it ran fine. Korren9 1 Quote Link to post Share on other sites
Simon 1,045 Posted June 15, 2020 Report Share Posted June 15, 2020 A couple of things: 1. You need the JRE, not the JDK. The JDK is for developers. It will include the runtime environment that you need for HD, but also has a LOT of stuff that you won't need. The JRE is the runtime environment only. 2. Most likely, your system is prompting you to approve opening a downloaded application. If you missed the popup, you'll likely see it in the Security & Privacy section of your System Preferences panel. Also note that you need to have HD in a directory that you have full read-write permissions to. Korren9 1 Quote Link to post Share on other sites
Korren9 0 Posted June 15, 2020 Report Share Posted June 15, 2020 Thanks to both Simon and Brian, but neither of those solutions worked. I know about the "Unidentified Creator" and I typed in admin password to bypass that. After doing that the first time, it said it needed JDK and wouldn't do anything and sent me to the Oracle site to download it. (I'd uninstall it, if I knew how, just to get the error message screenshot!) I'm running OS X Yosemite v 10.10.5 on a MacBook Air (13-inch, Early 2015) I don't know which version of Java I'm running, though. Where do I look that up? I know there's no Java "Program" to start up, otherwise I'd select Open File and try to find the HD software from there! Thanks, Corey Quote Link to post Share on other sites
Simon 1,045 Posted June 15, 2020 Report Share Posted June 15, 2020 It's sounding increasingly like you don't have Java installed properly on your system. Open a terminal and enter java -version That will run Java and output the current version that is installed. Quote Link to post Share on other sites
Korren9 0 Posted June 15, 2020 Report Share Posted June 15, 2020 After figuring out what the hell a launchpad and a Terminal was (thank you, Google!), it gives me this error: Error: dl failure on line 558 Error: failed /Library/Java/JavaVirtualMachines/jdk-14.0.1.jdk/Contents/Home/lib/server/libjvm.dylib, because dlopen(/Library/Java/JavaVirtualMachines/jdk-14.0.1.jdk/Contents/Home/lib/server/libjvm.dylib, 10): no suitable image found.

Simon 1,045 Posted June 15, 2020 Report Share Posted June 15, 2020 Yeah...you don't have Java properly installed. I'd remove the JDK that you attempted to install (google is your friend as that is going to be well outside of the purview of this site). Once that's done, go to java.com and install the current JRE -- it's the big red button that says "Java Download" Korren9 1 Quote Link to post Share on other sites
Korren9 0 Posted June 15, 2020 Report Share Posted June 15, 2020 That seems to have done it! Thanks, Simon!! Thanks, Corey Quote Link to post Share on other sites
Brian Stanfield 573 Posted June 16, 2020 Report Share Posted June 16, 2020 Wow! That whole process was almost as complicated as making a Champions character by hand . . . Korren9 1 Quote Link to post Share on other sites
Simon 1,045 Posted June 16, 2020 Report Share Posted June 16, 2020 Yes, of course....helping someone troubleshoot a bad installation of Java (not HD) means that pen and paper (and keeping track of all of the HERO System rules surrounding character generation) is easier. Couldn't be clearer. Brian Stanfield 1 Quote Link to post Share on other sites
