tag is not shown on Mac

[baj2012]

Hi,
I am running into problems showing a tag that I manually add on a Linux system and then cannot reproduce on a Mac:

On a Linux machine I use the following to set the three variables.:
exiftool -humidity=$hum -temperature=$temp -runIdx=$iter $fpname.n.tiff

I can verify the tags:
(classic)localhost:~$ exiftool 88.001.2020-07-07-17-09.mora.tiff -Temperature
Temperature                     : 21

I then transfer the TIFF to a MAC,

On the Mac I cannot see the tag anymore:
./exiftool /Volumes/mora2/moraImages/88.001.2020-07-07-17-09.mora.tiff -Temperature
=> nothing

I have even copied back the TIFF to the Linux machine and was able to see the tag value.

I am using version 11.26 on the Linux machine

On the Mac I have tested: 12.01 and 11.30

I am not sure if I can easily update the Linux machine for various reasons and would prefer a solution where I modify the Mac.
I also don't the tag in the System viewer.

Any help is appreciated.

(the files are about 47M big so I am not including them)

Thanks

Bernd

Hi Bernd,

Can you try to reproduce this with a small test file and post the file so we can take a look?

There should be no difference between the Mac and Linux versions.

Here is what I did:
(classic)localhost:~$ exiftool -temperature 88.001.2020-07-07-17-09.mora.n.tiff
Temperature                     : 21

convert -crop "10x10+10+10" 88.001.2020-07-07-17-09.mora.n.tiff sm.tiff

exiftool -TagsFromFile 88.001.2020-07-07-17-09.mora.n.tiff sm.tiff

(classic)localhost:~$ exiftool -temperature sm.tiff
Temperature                     : 21

copy to MAC; verify that temperature is not a tag; post here.

Are you forgetting a Config file?

temperature and runIdx are not standard tags.
C:\>exiftool -P -overwrite_original -humidity=99 -temperature=99 -runIdx=99 y:\!temp\Test4.jpg
Warning: Sorry, temperature is not writable
Warning: Tag 'runIdx' is not defined
    1 image files updated

C:\>exiftool -g1 -a -s -humidity -temperature -runIdx y:\!temp\Test4.jpg
---- ExifIFD ----
Humidity                        : 99

I see a value of 21 in EXIF tag Exif_0xd000, followed by a value of 121 in EXIF tag Exif_0xd001.

Oups... Indeed with the config file it works.

Thanks a lot. Not sure I would have ever found this one...

Thanks also for being so responsive!!! (and efficient )
