#39 NCIDpop no longer working on Mac OS Catalina

[Anonymous]

NCIDpop will no longer launch on Mac OS 10.15.1 (Catalina). Is there a fix or upgrade available or in the works? Screenshot attached.

Many thanks for a very useful system (NCID and pop)...

Hi Anonymous,

It'll be about a week before I can get access to a Mac running Catalina. In the meantime can you let me know the following:

1. What do you see when you click on "Learn More..."?
2. Which installer did you use -- the one in NCIDpop-MacOSX-Compat-0.10.11.0.dmg or
   NCIDpop-MacOSX-0.10.11.dmg -- or did you try both?
3. Can you confirm the installer(s) you used completed successfully?

1. Learn More takes me to the following link:

2. I installed "NCIDpop-MacOSX-Compat-0.10.11.0.dmg" about a year ago. Didnt try the other installer. When I get a chance I will try that version and let you know the results.
3. Difficult to say for sure that the installer completed successfully since I installed it so long ago. All I can say is that POP has been running well since then. NCID has been running fine, and continues to run, on my Raspberry Pi 3B+

Hi John,

Thanks for this info. Just making sure I understand the sequence -- NCIDpop was already installed when you upgraded to Catalina?

You might try the instructions in the linked article to find the no-longer-supported 32 bit programs on your system.
Since NCIDpop runs in a Java runtime environment, I'm wondering if you have a 32 bit version of the Java jre.

Hi John,

Could you type the following in a Terminal prompt:

file /Applications/NCIDpop.app/Contents/MacOS/JavaApplicationStub

I'm expecting one of two responses:

#1

/Applications/NCIDpop.app/Contents/MacOS/JavaApplicationStub: cannot open `/Applications/NCIDpop.app/Contents/MacOS/JavaApplicationStub' (No such file or directory)

or

#2

/Applications/NCIDpop.app/Contents/MacOS/JavaApplicationStub: Mach-O universal binary with 2 architectures
/Applications/NCIDpop.app/Contents/MacOS/JavaApplicationStub (for architecture i386): Mach-O executable i386
/Applications/NCIDpop.app/Contents/MacOS/JavaApplicationStub (for architecture ppc):  Mach-O executable ppc

Do you get #1 or #2? Or something else entirely?

I just installed NCIDpop-MacOSX-0.10.11.dmg. It installed without incident. However, Mac OS refuses to run saying it can't verify the app is free of malware (screenshot attached).

Thanks,

Now you're seeing a Catalina feature to protect you from things that have not come from the App Store.
You can authorize individual apps.

Todd,

I receive the first response; "...no such file or directory".

Ed,

I looked at the system info. The version POP that was running says 32-bit (unsupported). The POP version I installed this evening says 64-bit. But, as noted in my earlier response, the system will not allow me to launch the app.

According to this link, Java isn't certified yet to run on Catalina -- doesn't mean that it won't though.

John, if you go to System Preferences->Other, do you see an icon for Java?

• If not, you'll need to download and install the latest version of the Java runtime environment as mentioned by Ed in his earlier post. Click here to directly download the latest Mac version
  
  
• If you do see the icon, click on it and then go to About to get the version info.

I hope the above info works. I'm still hindered by not having access to a Catalina Mac machine.

Success...

I wasn't able to find Java in System Preferences --> Other so I just went ahead and installed the latest version of Java from the link you provided. Prior to this NCIDpop was not listed in the "allow app" area of System Preferences --> Security and Privacy --> General. After installing Java it was listed, I allowed it, and it now works.

Big thanks for the help and sorry for any headaches my request has caused.

CLosed.
As I understand it, the cure is to install the NCIDpop-MacOSX-0.10.11.dmg (not the Compat version) and get Java from the Oracle site.

And allow the NCIDpop app to run under the Security and Privacy section of System Preferences.
