OS X 13 wont read SanDisk Extreme PRO SD cards. They dont show on the desktop but do in Disk Etility

1 Yes the same SanDisk PRO always work perfectly on my MacBook prior to upgrading to OS X Ventura13.0.1

2 No error messages have appeared, neither has the disk icon for the card on the desktop.

3 The SD cards are formatted on my Fuji XT 4 in the same way as always. I have reformatted, changed cards etc without changing the read problem.

4 The card is visible in the Disk Utility but does not show on the desktop, so the reader is not at fault.

5 SanDisk SD cards of lesser capacity (and older) do work as normal, and are visible on the desktop and in Adobe Lightroom, whereas the Extreme PRO cards now cannot be read.

6 It seems to me that the Ventura upgrade is the only thing that has changed.

I did as you suggested with several cards Disk Utility report Mac OS Extended (Journaled) This is a surprise to me as the cards are initialised in my Fuji XT 4 camera where I use them. I checked the older smaller capacity card with the same result.

Surely Ventura should read a Mac format? So I checked the CD card that does report on the desktop. It has a sub folder where the image files reside and that is formatted MS-DOS (Fat 32) The camera must do this?

The root folder on this (working) card is DCIM (set by the camera?) and the sub folder is MCEC - I must have named it this sometime, that is my initials. It is still showing on the desktop but the bigger capacity PRO SD cards (I have many) still do not work in Ventura.

But wait there is more. I now checked in Utility the sub folder on the PRO SC card. This shows grey in Utility but it's format does reads and is ExFat - different from the smaller CD card. (This card is branded PNY and is 8GB. The PRO cards are 64Gb and 128GB.)

I hope you can sort this out for me. And thank you for your interest

Thanks Justinb

The problem is that the camera (Fuji XT 4) has to format the SD cards.

OS X 11 etc has always allowed the very same cards to be read in Adobe Lightroom which is what many photographers use with Mac. The new Ventura OS X 13 has changed all this, it just won't allow reading although the disk is there in Disk Utility, the subfolder containing images is greyed out but can still be read as ExFat just as it always has been.

The only change is Ventura. I can seem to get this across to anybody.

I hope that is more clear now.

OMG that worked! Usually cards must be formatted in camera, its is a safety issue for avoiding faulty cards.

So I took the card a I just made work using your in-computer method and formatted in the Fuji camera. And now it does not read on the desktop. The Master folder is Mac OS extended and the sub folder is ExFat, as before. So the camera did that?

So I did it again - format in Disk Utility both folders are ExFat. Put I into the camera, took photos, Ventura reads the card, Lightroom reads the card. Disk utility says The top folder is Mac Extended and the sub folder is ExFat.

Again Format in camera and again Ventura cant read the card.

Strange? What to do? I have to have clean cards each time I shoot.

Judy I tried sorting else. I got my old Fuji Camera an XT 2 Took out the card, same brand as before but a different cad and an earlier Fuji OS.

Same result in Ventura won't read the card and the Top Folder is Mac Extended and the sub is ExFat so its not a Fuji problem is it?

Thanks JudySings

Is it possible for you to prevail with The gods who wrote Ventura?

I have approached SanDisk and Fuji with the problem but no luck as yet.

You were pretty smart to think of the workaround though!

I will keep on working on the problem.
