can't be opened because the original item can't be found

Hi,

I am using a late 2012 iMac with El Capitan version 10.11.4.

I also have a older model Time Capsule in my network, and a Synology NAS. Both of them show up under Shared in Finder.

After not using my iMac for a short while, let's say 15 minutes or so, I cannot see the contents of my Shared devices and the following error pops up:

"disk name" can't be opened because the original item can't be found

Time Machine still seems to work and I can open excel files from my NAS directly from Excel.

It's only Finder that has a problem with the shared devices.

Workarounds so far are:

-relaunch Finder

-reboot Time Capsule

I have never seen this problem before until recently. My network hasn't changed. I'm using wired gigabit ethernet.

The problem is also described here:

I don't think it has anything to do with Synology, since the Time Capsule has the exact same problem.

Any solutions or ideas?

Thanks

iMac, OS X El Capitan (10.11.4)

Hardly a "Solution" or "Fix".

At best this is a workaround for a long standing bug in OSX!!

Come on Apple! Shame!

Just happened to me on High Sierra - key worked fine a few days ago and works fine on my Windows PC. Force restarting Finder hasn't helped.

Basic things like USB drives not working in 2017 is annoying

Same problem here. I have to use my Windows PC to open CDs !!! This is Crap Mac!

Agreed. I have to use my 1st generation ipod because it has a headphone jack.

if it's exFAT it does not work on High Sierra (looks like a bug or a very DUMB new feature). FAT/FAT32 works.

Correction: I might be wrong about FAT32. I think only FAT seems to work. Feel free to test it with a fresh SDHC card or USB stick.

Wonder when this problem will be solved. I have the same problem already for some time, on my older Mac and now still on my 2017 MacBook Pro.

The only workaround I have is: Open Finder and then in menu Go, select connect to server (Command+K) and then connect to ip of my NAS (or network connection) directly.

Also rebooting my laptop helps for a short time.

I have the same problem with a Synology NAS and MacBook Pro connected via wifi. Force quitting and relaunching Finder worked for me. It seems my NAS was in sleep mode until I relaunched Finder. I heard it turn on and saw the status light change as soon as Finder came back up. Not sure if there's a way to wake it up without relaunching Finder, though.

I just found a solution that worked for me via the link below:

https://www.cnet.com/news/fix-shared-computer-not-found-in-finder/

The first option worked for me.

"To fix this problem, you simply need to relaunch the Finder, and it will re-populate the list of shared devices. To do this, you can do one of the following:

1)Hold the Option key and right-click the Finder icon in the Dock, then select Relaunch.
2)Press Option-Command-Escape or choose Force Quit from the Apple menu, then select the Finder and click Relaunch.
3)Log out and log back in to your user account

just to add some details:

a macbook on the same network, but on wifi instead of cable and el capitan version 10.11.3 instead of 10.11.4 does NOT have this problem.

I found out that this problem only exists on the iMac when it is on ethernet cable. When I turn off ethernet and turn on WiFi, the problem doesn't seem to occur.

Hey mate,

Same problem here. Interestingly, the following is also true for me:

Synology (DS13xx+)
Works after force quitting Finder.

I don't use Time Machine but I do use wired gigabit ethernet. Additionally, I use it through a CalDigit Thunderbolt dock. I particularly notice it when I go between docked and undocked scenarios.

It's happened for ages for me and I've searched often - this is the first time I've found anything meaningful. Let's hope we get somewhere!

Cheers!

Hi there

you've had this problem before El Capitan?

for me it started just a few days ago after my fusion drive had been replaced and came back pre installed with the very latest Mac os.

I was wrong about the wifi. The problem is on both wired and wifi connections.

It is a very annoying problem and unfortunately my Apple care has expired.

I highly doubt it has anything to do with Synology.

Lets hope for a quick solution

regards
