High Sierra and problems with sharing with previous MacOS versions

[Astavroulis]

My MacBook folders were shared with my secretarie’s MacBook 2008 (that cannot be upgraded any more). After upgrading my mac to High Sierra she cant use the sharing functions as before. E.g. was using the search function in finder to search the files (eg excel) on the shared drive on my mac. Now when search for the file she can get the name of the file but the not as excel; the excel icon is not on the left hand side of the file name but instead another icon and cannot enter it. In other words since i upgraded to High Sierra she lost the part of the search function for the shared part. Thank you for the help

this worked with afp-file sharing, it doesn't with the new standard smb sharing. Try re-activating afp file sharing and eventually disabling smb in the network preferences.

Browse this thread, it has a terminal command direct from Apple that will resolve this:

My guess is that before updating to high sierra you were using the afp - network protocol. It seems afp has some advantages over smb relating to network indexing and spotlight, metadata etc. Not being sure about this I would set the network protocol to AFP, restart and try connecting.

beforehand check for apple's latest security-update. It fixed the previous bug for filesharing and your latest version of high sierra should be 10.13.1 (17B1003).
-> to check this open the  menu and open "about this mac". Click on the version-number and the exact OS-Version appears. if you read (17B1002), head over to the app store and update your OS.

-> open system preferences / sharing (in the 3rd row), select file sharing (2nd entry on the list) and click on options on the right side. A submenu opens with selectable options, now deselect sharing through SMB and select AFP. Click done, close and restart your mac.

If it still doesn't work you have eventually manually fix the bug from the latest software update.
-> open terminal (search through spotlight or find it in the folder Applications/Utilities/Terminal) and enter the following line of code:
sudo /usr/libexec/configureLocalKDC into terminal
confirm with your password (you can't see any characters while typing, just enter it blindly and hit enter).
Restart you mac and try reconnecting.

Hope the problem is related to this. Good luck.

unfortunately did not work -- the afp option doesnt get recognised buy the other mac, the smb option allows the otehr mac to recognise my mac but still the problem exist, even after fixing the bug as you suggested. Whilst playing with the above options and restarting my mac at some point it started working but after a while it stops. I repeat, what happens is, when the other mac searches on mine an excel, i get to see the excel icon next to the name of the file but after a second the excel icon disappears and instead i get a white icon and the file cannot be open.

Another weired thing, is that looking on the on the other mac to check the shared folder, i can see there that it has also have acess to my main macbook folder (Kasa) although on my mac it doesnt have this permission shown. ???
thx

sorry it didn't work out, unfortunately I can't help you further.
However, the problem with the icon could be related to a missing xls-file extension. On the local MAC it's no problem because the OS reads the files metadata and embedded resource forks, thus even without a file-extension it knows how to handle that file. Obviously metadata somehow doesn't reach through your network, which is why the other mac has problems opening that file because it doesn't understand the file-format. Adding the file-extension should make it readable for the network-mac and should open just fine.
Otherwhise, if there is a file-extension, it could be that the local excel-app is missing or somehow isn't registered in the OS. Then I would suggest to reinstall excel on the network-mac, restart and retry.
best of luck...

Well, it seems we are on to something - I could replicate the bug between 2 high sierra macs with latest OS, sharing the same network through SMB.
Trouble occur in the finder window, when I copy a file from the local mac to the network-mac. What's happening is exactly as you describe - in Finder, the copied file looks normal after the copying process, just a second later it looses its icon, sometimes turns into a semitransparent white icon and when I check the file information, it doesn't show the full file-size but e.g. half of it.
Checking the file in Path Finder (a Finder alternative) everything is fine. The icon, the file attributes, all can be treated just as usual. So it seems this is a High Sierra Finder bug and hope this gets ironed out with the next update.

Workaround:
You can actually access the file, if you duplicate the file in the Finder Window of the network-Mac by pressing +D. Instantly the file-icon turns normal. Just trash the duplicate afterwards.

Documentation by Apple:
In macOS Sierra 10.12 and earlier, your Mac gathers all metadata for the files in a folder, compares it to the folder's .DS_Store file, and then displays the folder's contents. In macOS High Sierra 10.13, this behavior is changed slightly:
Adjust SMB browsing behavior in macOS High Sierra 10.13
-> https://support.apple.com/en-us/HT208209

Force the Finder to gather all metadata first ->
matching the file browsing behavior of macOS 10.12 Sierra and earlier. Use this Terminal command:

defaults write com.apple.desktopservices UseBareEnumeration -bool FALSE

Then log out of your macOS account and log back in.

-> I guess this is the key to the behaviour you're experiencing, you could try this command and it should work as with previous OS-releases.
