Thanks much for the clarification. According to the Wikipedia entry for "Retina display," all desktop/laptop Macs to date employ a pixel density well under 300ppi, so -- as you've indicated -- my 300ppi images should render just fine for the foreseeable future. (I suppose that the issue would be of ...

A couple of years ago I wrote a LC app -- intended solely for macOS and Windows -- that models a classic neuropsychological test. It displays a series of approximately 330 images, to each of which the respondent must answer (via keyboard) with a number between 1 and 4. It works just fine. Here's the...

Consistent with LCMark's suggestion, the warning that Rob quoted at the top of this thread This app needs to be updated by the developer to be able to work with this version of MacOS. sounds like the one that's been displayed by recent versions of macOS in order to encourage end-users to prod develo...

Klaus -- I did mention in passing that I'd opted not to include the support files (audiofiles and plain-text norms files) in the standalone bundle in order to streamline the distribution of updates to the test norms. There are 740 audioclips (totaling about 250 MB), which are not expected to change ...

One last quick question (understanding that this forum is specific to macOS): I will of course implement Klaus' recommendation and have my Mac users copy (manually) the subfolder containing my application's support files to its corresponding Documents subfolder, created automatically upon the initia...

Klaus --

Thanks for promoting the strategy of saving all read/write program files to the macOS and Win Documents folder.

Where should I send the check?

bogs -- You're right of course about error checking. The application did originally check upon launch for the support files, but I'd assumed (incorrectly) that if "there is no file filePath " returned true, this was simply because the file didn't exist (e.g., had been deleted or renamed by the user)...

Okay. I provided the student running macOS Catalina with a $10 gift card and a standalone version of the application (built with LC Indy 8.10) named EAS-SABE-CHK that included a zillion error checks. At least with this build, the specialFolderPath("engine") apparently is broken in Catalina. (sorry, ...

Jacque -- I definitely will provide the one current Catalina user a build that includes much more robust error checking, so hopefully we'll get more informative error messages. I was remiss in not appending "for read" in the call to "open file", which might have caused the failure in Catalina (inasm...

The student having the problem with Catalina reports that she did indeed copy the folder containing the standalone and support files to her Applications folder. The structure of the folder containing the standalone is as follows: /EAS-SABE /EAS_Audiofiles -- (a folder containing 740 .wav files) EAS-...

Well, I've just heard back from the student running macOS Catalina, who reports that the app still fails to recognize the resources contained in its subfolder when employing the recommended specialFolderPath("engine") function. (To reiterate, the code employed formerly had worked fine up to and incl...

bogs -- I am rightly chastened for having overlooked the solution you offered back in November 2019 -- essentially the same as Jacque has posted here. My only (lame) defense is having followed the (now obviously) outdated LC tutorial as gospel. I will be more circumspect -- and more dedicated to due...

Jacque -- Your solution worked like a charm, of course. Tested here it through macOS Sierra, which by your account also works at least through Mojave. I'm just awaiting word back from the student for whom the app broke in Catalina and from one who runs Windows. I'll update here what they report. Usi...

Hi Jacque -- My fault for not providing the full snippet, which would've shown that the issue involved a Mac standalone: put the effective filename of stack "EAS-SABE" into tStackPath if the platform = "MacOS" and the environment = "standalone application" then put char 1 to offset("EAS-SABE.app",tS...

Back in November 2019, forum member Hermann provided a very elegant snippet of code to identify the path to the subfolder in the Mac Applications folder that contained my standalone (EAS-SABE.app) and supporting files: put the effective filename of this stack into eF put char 1 to offset("EAS-SABE.a...
