Thanks for the info Ian.

1. Depends on the team doing open source. A perfect example of things gone wrong is LibreOffice. It's been taken over by script kiddies that focus on glitter and break decades old functionality, rendering the product almost unusable by keyboarders. If you can manage the product development by assigning tasks to competent programmers, go for it.

Any open source as a group thing needs to be run from a development plan with agreed tasks and controlled updates. If people want a free for all, they can fork the software and do as they wish - it shouldn't be allowed to impact the core product.

I'm not a software guy, but if anyone knows where the resources are to work through this installation issue, I'd take a stab at it.? LOL, it'd be a real shot in the dark so to speak.

Hi Chris, I did write a reply to you on May 9th over Mac security constraints and the fix - did you get to see it?

You know that your TSC got re-written in JavaScript.

Hi Paul,

Yes, I saw the Javascript version - it's really good. In fact it was so good and worked on any system with a browser, so it did not make sense for me to continue developing the Windows version of TSC.

Hi Tom,

PSU Designer available here has Windows and Mac versions but no Linux version, sorry.

Duncan

At one time about 6 months ago I was in an io group where there was a program you could use to design a power supply, made available through that group. Not long after that my Windows 7 laptop crashed with a bad hard drive. I got another hard drive and put Linux Mint 21.1 on it. So I lost all my groups and log-ins.? Does that design program work on Linux and how do I get it? Thank you, Tom Finley, Monroe NC. htfprinting@...

As such it runs in any 'good' web browser; just checked linuxMint.

An amazing effort. Of course a tone control is linear and an AC-DC power supply is at its core non-linear. Beyond that, I can't say how awful JavaScript is as a calculating language. And prime author jatalahd seems to be busy with other projects.

Sensible suggestions:

2. Definitely a sensible option. I have friends who've used Mac's for 40 years and have a collection of old boxes to run applications obsoleted by non-support in later OS & platforms.
3. See Pareto. Nearly 80% of platforms are Windows. Given Apple's propensity to bust applications with OS releases, 80% of the work will be spent supporting 15% of the market. Speaking as a retired software developer and hardware engineer, I'd gladly contribute to $$ supporting PSUD.

Hi,

Thanks for picking up on this. The .dmg file uploaded here is meant for Intel hardware only I'm afraid. Sorry it didn't work for you, I'll make the files page more descriptive on this.

My current setup is a MacBook Pro using Intel i5 processor, that's all I have available to me to develop and test the product. It's not viable for me to go out and get M1/M2/M3 hardware that I would have to pay for and use infrequently (PSUD is all done for free so generates only cost - no income). This is going to be a growing dilemma as the Apple hardware base migrates to newer processors.

I'm having a think about what the options might be around this.

1. Open source PSUD 3 and later versions to allow a wide community to help with development and code testing
2. Phase out Mac versions of the product and support
3. Start some sort of charging model for the product to enable more hardware for development

Open to sensible suggestions...

I'm getting an error when trying to run the builds for MacOS in the Files. Is this because I am running on a M2 Mac? Thanks.

Hi Chris,

There was an issue identical to this picked up in late 2020, it was linked to a MacOS upgrade which locked down the security tighter. There's a fix for it, but the permissions need to be applied at the Mac end (I can't do anything in the software). There's a thread listing the error, explaining the issue and finally providing the fix:

/g/duncanampspsud/topic/77707176#msg20

If you get an opportunity to try, please feed back and let me know if that fixes things for you.

Hi,

There's a note in the files area, however it is pretty vague as it doesn't give any OS version numbers:



I'm not sure how far back PSUD will work as I only have the one MacBook Pro to support this and I always keep it on the freshest OS version. I do know however that PSUD has worked on MacOS 12/13/14, so MacOS after October 2021 should be fine with the downloads on this site.

Had a look at the release dates and MacOS X 10.7.x was released in July 2011 so I couldn't guarantee this would work - it's really far back down the release chain.

Would be handy if others are on a non-recent MacOS if they could post what it's working or not working on? This would allow me to give potential downloaders a more accurate set of guidelines to work with, thanks.

Duncan

Hello:
Downloaded Mac OS builds 75, 77 neither worked-
"the following disc images couldn't be opened"
psud2.build77.dmg- no mountable file systems
I'll assume my mac is too old?- 3.1 macPro running OS 10.7.5 at the moment.

Thank you.

Look at the tab FILES see photos

Hi,

You posted on 21st March last year that you couldn't download it. I asked for some more info but never got a reply ->?/g/duncanampspsud/topic/97773153#205
You raised the exact same issue on 2nd January, I referred to the questions from 21st March, but again, never got a reply ->?/g/duncanampspsud/topic/103479180#267

I'm only going to be able to help you if you provide some clues as to the issues you are having.

Duncan

OK that's a good bit of info, thanks.

It does make me concerned though, as the model is the same for all the diodes; solid state as well as vacuum tube. At least I can duplicate the issue at this end, and to be honest, that's half the battle with fixing things :)

Regards,
Duncan

I noticed it seems to be related to the valve diode model, as HV valve diodes (eg. 575A and 3B28) show symmetric behavior.?
