LV 2009 MAC Application with VISA

[Intaris]

I have a customer complaining that an old build of some software I wrote will not execute (won't even start) on a Yosemite installation (Mac OS X 10.10). 

He wanted to do a demo and the software just didn't even start properly.

Does anyone know if this is a LV or a VISA problem?  I am using VISA USB RAW communications in the code with whatever VISA version was shipped with the LV 2009 SP1 DVDs.

It's definitely a VISA problem -- Yosemite requires signed binaries for kexts, frameworks, and applications. The VISA binaries are not being loaded anymore.

Update to VISA 14.0 -- https://www.ni.com/en/support/downloads/drivers/download.ni-visa.html#306022 -- and try again 🙂

Joe,

thanks for the help.  I've forwarded the information and will update as soon as an.

Oh, and that's the best avatar I've ever seen.

Jen: What is it?

Moss: This, Jen, is the Internet.

Jen: What?

Moss: That's right.

Jen: This is the Internet? [Moss nods.] The whole Internet?

Moss: Yep. I asked for a loan of it, so that you could use it in your speech.

Jen: It's so small!

Moss: That's one of the surprising things about it.

Jen: Hang on, it doesn't have any wires or anything...

Moss: [rolling his eyes] It's wireless!

Love it.

Just don't type Google into Google 😉

 I should clarify that VISA 14.0 does not claim support for Yosemite, but preliminary testing looks good. Please deliberately test your application before moving it to production.

Well my customer is happy, said it worked fine.

So that's one good feedback at least.

PS BTW, a bit of a gripe: When looking at the compatibility notes for VISA 14, it says it supports LV 2011 onwards.  My software was compiled in LV 2009 but it works fine with the new VISA version.... The compatibility relates only to the IDE or what?  How far back does the compiled binary compatibility go?

NI drivers are typically validated against the latest four versions of LabVIEW to match the LabVIEW Life Cycle policy [1], which includes testing in the IDE and in built applications.

Changing a driver interface is costly for both customers and NI, so every attempt is made to keep it compatible. The life cycle policy does allow NI to fix selected design defects, but those occurrances have been rare -- I can't think of one right now. In addition, VISA is governed by a standards body which further cements the interface's stability.
