SD Card not showing up in Finder Sidebar (other removable drives do) - Big Sur

I was unable to find an SD card in finder, desktop, or disk utility. I did a ton of searching on the internet, finding nothing. I am using the Satechi USB-C Multiport Pro. I plugged the Satechi into my work laptop (Lenovo) and added an SD card. Card showed up immediately. I ejected, and repeated the process with a micro SD. I then brought the Satechi back to my (Brand new) MacBook Pro, plugged in an SD card and... It worked.

No idea why, I had combed through every possible setting and visibility before trying this. Hope you find success.

I've run into this problem as well. While it's a work around, after renaming the card as suggested by others, you can drag it over to the Locations section in the sidebar. Of course, this doesn't help once the card is reformatted but at least you don't need to reboot or relaunch finder or eject and reinsert. Seems like this should be a simple fix on apple's part. We'll see if they actually address it since this is at least 3months old now.

I have a similar experience with my Macbook M1 running Big Sur. I have a couple of sd cards that I use with a sony mirrorless, the workaround worked for them (force quit finder, rename the cards, etc.) but my sd card that I use with a canon mirrorless will just barely show up, but I can't read anything on it. All these cards still work just fine on my Mac mini under Catalina. 🤨🧐

SD cards are recognized in the Finder side bar:

Be sure you have all of these checkboxes checked in the Finders/General preference pane:

However, I don't know how to see it in full screen mode in an app without going to the Finder to get a Finder window.

That is not a fix, that is a bandaid.

Some (such as myself) have an SD card known to contain rights management shenanigans so we dare not modify the card outside specific instructions from the vendor.

Specific example: Subaru navigation map. Only costs $150 to replace damaged card.

To find your SD card open Terminal.app

type: ls /Volumes

Get something like this (I don't have an SD card attached at the moment but do have 2 Time Capsules).

My Sony SD cards won't show in the sidebar on a 2019 16" MBP. I can see them under the computer name but I can't see that in the Final Cut Pro import dialogue. This is killing my video workflow, please fix it Apple.

I posted months ago about this issue and I can't seem to find that thread.

But after the last OS update, the issue seems to be resolved, at least for me.

I use Sony cameras and cards and reformat every time it goes in the camera for a shoot.

The cards now show up in the sidebar and my workflow is back to normal. Finally.

Hallelujah.

Try dragging the HD icons from the Desktop into the sidebar of a Finder window.

It seems to be working for most of us:

Have you run any "cleaning", "optimizing", "speed-up" or anti-virus apps on your Mac?

go to your desktop and open a Finder window and drag the icon from your desktop on the sidebar of the finder. that fixed the problem.

I found the card is mounted at /Volumens/Untiteled\ 1 and is accessible there. It just does not appear in Finder.

Also on pulling the card out a message shows saying it was not ejected properly - so the system clearly knows it is there.

Same here. A temporary workaround is to rename the card from the desktop. Then eject and reinsert the card, and it will show up in the sidebar. There is a bug where Big Sur gets confused when a card has a default 'Untitled' name. I really hope this gets fixed in the next update as it has severely slowed down my workflow!
