P: Can't access some network files on Apple Silicon M1 Mac "because the file is locked"

You can use an Applescript to refresh the Finder view, similar to F5 on Windows.

Interesting idea but might be difficult getting a freeware alternative to a native OS system approved by any IT department. 😕😕

I know that Pathfinder isn't really a "replacement" - it runs on top of the Finder and still had similar issues.

I have both active on the share settings.

Tha is a very good point.

I rarely use Mac now-a-days and when I do, I don't use finder that much.

Maybe by using a diferent file explorer would be a solution?

Anything having to do with the Mac OS Finder application will cause this issue. Quicklook, Preview in column view, renaming a file on the server, etc. will cause the affected files to "lock" as the Finder is not refreshing across the network connection (doesn't matter AFP or SMB, QNAP, etc).

This has been an issue for years, its not new to M1/2, Mac OS Moterery or Ventura, but that has made it worse.

I have tested and tracked down what I believe is the problem and a workaround.

I tested MAC OSX 12.6 and 12.6.1 on a Mac Studio M1 Max with 64 GB RAM.

Connecting over SMB to a QNAP. Photoshop 2022  23.5.3

I Created a folder, created a photoshop file and saved as .jpg and .psd.  PSD generally have the error when trying to open from file open, or finder right click file open.  It would open from recents most of the time in photoshop.

I found that if opening from the finder right click open with, or boule click, or trying to open from file open photoshop if the Finder is in the Column view it doesn't open,  If I change finder to Icon or List view the files open.  Also if I make two windows, if the column view is on in one of the windows, I can't open from it or the other window that is in list or icon view.  If I change the two windows to a combination of icon and list or both icon or both list, the file opens.  Anytime there is an column view in finder the file gives error.  So I think this is related to the Finder and Quicklook process over SMB on Apple Silicon keeping the file open.  As quicklook preview isn't being used on icon or list view in the finder.

@danielg80489600 But do you connect via AFP or just have it activated and still use SMB? AFP is deprecated and not recommended anymore by apple.

Hi,

Not sure if it's the case for everyone facing this issue.

But for the ones using a NAS, can you activate the AFP protocol on the NAS Shared folder where you have your files?

I used to bypass this same issue by connecctiong to the Share/Folder using username and ip address, but recently I have moved most of my files from a Netgear NAS to a Qnap NAS and activated both SMB and AFP protocols for te folders I need to access on the Mac and haven't faced this issue.

Activated the AFP as well on the Netgear NAS shares that I still use, and no issues as well.

Also, it might be relevant and/or helpful, I have SMB 1.1 deactivated, using SMB 2.0
I am still on Monterrey 12.2 

I talked again with Apple, this time their technical support. They said that they can't actually help there, because SMB and network stuff isn't their area of responsibility. For that I would have to get in touch with the business apple support which is paid and only available when I got a specific contract with apple.

What they did today is resetting my user permissions with this terminal command (use at your own risk): 

diskutil resetUserPermissions / `id -u`

They also pointed out (the standard thing) that is worth trying another user on the same device.

Unfortunately I can't reproduce this issue 100% of the time. Annoyingly this only happens when I actually work, not in the 15mins I was in the telephone queue. There I could open everything perfectly. demonstration effect

So for me it's not narrwoed down enough to replicate it every single time. Even after a full restart the error didn't came up again. But I swear that it will happen tomorrow.

I will keep you updated if the terminal command actually did anything (I doubt that).

I also agree that to some amount this isn't a adobe bug/ problem.

Mounting the drive with username/password in the URL doesn't change anything for me.

The opening two files at once workaround does work. Seems to point to an Apple issue, not an Adobe one in that sense, but I'm not a programmer (anymore).
