I cannot get the calculator to update currency exchange rates. This seems to be a recurring theme in other OS versions, but I did not find it posted here.

Per my original post:

even though this computer seems to meet all known criteria for doing so: It is connected to the internet. The language, time and timezone are correct. Location data is allowed in the security preferences.

I located the preference file in my home directory and moved it to the trash, and restarted - this did not correct the problem.

It still indicates 11/15/12 as the date that currency data was updated. I did not really expect a change in my personal directory to correct the problem. The reasoning is that a whole set of new preference files were created directory for the new administrative privilege user and that user had the same problem. Is there a system-wide preference somewhere?

I did find other plist files in that location that were indicative of prior crashes and tossed them. Most of them were zero byte files, but a few had data - a pair related to ichat were 304KB and 317KB. They date back to Jan 2020 and April 2020 respectively.

I made a copy of the calculator.app and tried replacing the "http://" with "https://" in rates file.. It did not update, but it otherwise seemed to function as the original unmodified one did.

I then tried removing the rates file to see if it would construct a new one, and had no success there - the app would work until I tried to do a financial conversion, then it would no longer function properly and had to be quit.

Thanks for the reply.

I've noticed the loss of widget functionality with a bit of sadness - it is a shame and kind of a dumb idea to even have that Dashboard application at all, if they are not going to function.

As you can see the from my photos, the Calculator app is not automatically updating.

The problem persists between multiple existing accounts, and a newly created account with administrative privilege.

I will try safe mode and update this status.

I just attempted the test after rebooting in Safe mode, and the problem persists. Is the a system-wide preferences file for the Calculator application that can be deleted, causing it to rebuild the conversion data?

After looking at that rates file, I think I know what is wrong with it and possibly why dropping a new one in did not work. The existing one uses non-ssl references to yahoo's finance page, but a browser goes to an SSL version of it. A text replacement on the existing file or replacement with a later one would case a mismatch of the hash data in the CodeResources file found within the _CodeSignature folder. I don't know enough to determine if it would be possible to just replace the rates file and copy the hash data from the newer versions CodeResources file into the old versions CodeResources file, or if there was an easy way to generate new hash data to stick in there. UGH.

Here is what it looks like in Xcode (there is no formatting, I just drug the window to about the correct size to allow it to flow in mostly intelligible) :
