Hello

A life-long Apple user I now have a MacBook Pro (which, incidentally, I really do not like) running Catalina 10.15.7 (latest incarnation) on which I have attempted to download PSUD2 on a number of occasions ~ and, as with the reports of other potential users, with little inner standing…

Rather stupidly I’ve come to realize I was attempting to enlist its help to replace?5ц3с?rectifier valves in a "standard Sun Audio 300B type CLC PSU ~ with Vishay Hexfreds (HFA16PB120HN3) which are 16A 1200Vr types purchased some years ago... and I'm completely out of my depth.

Today I did manage to override the OSX security warnings (not a recognised developer etc) and managed at least a "look-see" - and to my horror found I would probably fry similar? 1200Vr IXYS diodes. ?Do we?really?need 1800Vr (!?) I couldn’t answer that because,

no matter what I did subsequently the “security" would?not?allow PSUD2 to run ~ it came up with another error message about some rectifier or other not being found :-

Utilisling the programme is certainly not without difficulties and as others have suggested some more guidance would be very helpful. ?Otherwise this old Chemistry kid with a very old A level Physics experience and a new soldering station will need to copy established designs - e.g. Dr Jac van Der Walle’s ~ or see expensive things go up in frightening smoke - which is I suppose entirely the reason why such guidance isn’t provided for novices such as myself?
Have I answered my own question as far as that aspect is concerned ?

Hi,

The first time PSUD runs, it attempts to copy the set of standard rectifiers and example PSUs from the .DMG file to the documents area (it's correct practice on the Mac to store things there).

It sounds like you've got tighter security than my Mac has got, it's just a standard MacBook Pro with no customisation. Are you using a company provided device that is locked down or something like that?

Regards,
Duncan

Duncan, Hi

Although it probably doesn't take the issues any further I can confirm this is a bog-standard 2019 MacBook Pro and certainly not company property!? As for "customization" I have the usual Add-ons to attempt to defeat the scourge of adverts and pop ups and the like.

PS ~ yesterday it then came up with a further exception: ACCESS DENIED.

OK thanks for getting back so quickly, to be honest it was a bit of a shot in the dark.

I haven't used the Mac for a few months, so will get it upgraded on Saturday to the latest OS and try again - it may be that MacOS has some increased controls / security that have crept in since I last used PSUD on the Mac.... I'll upgrade then go through a full install again. More news soon.

Hi,

I've had a chance to look at this on the Mac, and have upgraded to latest Catalina.

The first time you try to run PSUD2, it will ask for access to the Documents folder. It needs this access to store the rectifiers and example files. If you say "No" at any stage, the access will be blocked and the error messages you show in your post will be displayed. MacOS won't ask you again, once you've said No, that's it, there is no second offer....

There's a way to retrospectively fix it by going into Security and Privacy settings which you can do by pressing Apple menu > System Preferences > Security and Privacy > Privacy tab. Scroll the left panel down until you get to a blue folder icon with the title "Files and Folders". Click it and the right hand panel will now show a list of apps and their access privileges. Scroll down to PSUD and make sure the box is ticked.

Hopefully there's a screen dump attached to show the screen I'm talking about. (It shows unchecked which wont work and that may be how yours looks, check the box and it try a reinstall of the .DMG file, should get things going again)

The following Apple article contains a bit more information about application access ->?

Hope this helps, please let me know if it fixes the issue.

Regards,
Duncan
