Hi Daniel,
Thanks for that info - that is all interesting & good to know. Things may well be different in later operating systems - I think that the last time I had these problems was when I (finally) decided to move from OSX 10.6 Snow leopard (my all-time favourite) to OSX 11 El Capitan (the last system that is compatible with most of my computers). I had also just rebuilt my main iMac (late 2009) with an SSD and new 3TB HD and took the RAM up to 24GB and decided to get rid of over decade of built up detritus by going with a clean install of El Capitan ( I keep a bootable clone of the old Snow Leopard installation on a separate partition on the internal HD but don't need to access it very often). So, I was not using the normal "migration Assistant" route between computers and I was not "sharing" over the network. I was basically setting up from scratch but pulling user info either between computers using target disk mode or from HDs with clones of the old setup. From memory, my problem happened when I setup one of the computers without first creating the admin account. I remembered having similar issues in the (further) past so I just backed out and created the user accounts as for the other computer(s) and that solved the problem. I am not surprised that, in the scenario you mentioned, it all worked fine - as I said before: " Each computer setup works fine on its own and, when sharing, you login using the correct details for the relevant account - so you can get access to the account with the same user name/password but different User ID. Then if you want to copy a document to your computer it will be given the correct permissions with you as owner. " If I understand it correctly you are logged into your laptop as UserID 501 but accessing the iMac as UserID 502 - but when you copy the files over it will change the file owner from 502 to 501 and, thereafter, they are "your" files on the laptop - no problem. As I say, I do not remember the exact circumstances when I have encountered these problems but it resulted in me not being able to see or have access to my own user data because the system thought it belonged to another user. When I read Matt's original email, my first thought was that his issues were connected with user permissions - so I suggested he check UserIDs and this confirmed that his problem iMac does, in fact, have a different UserID from the other two for what he considers to be the same account. Exactly WHY this is giving him the problems is hard to know without knowing the exact steps Matt went through when setting up the new iMac. I have just re-read Matt's original email and it seems to me there are two separate (but possibly related) problems: The sharing problem: The 2 older iMacs can connect to each other and the new iMac can connect to each of the older iMac – which suggest that sharing is setup correctly on the older iMacs. Neither of the older iMacs can connect to the newer iMac – which suggests that the sharing setup on the newer iMac requires re-configuration The permissions problem: The older iMac can connect to the newer iMacs and, presumably can access and copy files from them. However it cannot “save” files to them. I think this is because the newer iMacs see user 501 as being connected to them but the files/folders being accessed belong to user 502. These files/folders will presumably have the default “read only” privileges for other users - only 502 can “write” to them even though 501 has sharing access to view them. If the account on the new iMac had UserID 502 (as on the older iMacs) it would have “Read & Write” privileges on the relevant folders and so saving files to them would not be a problem Of course, without actual knowledge of the exact circumstances/details of Matt’s setup the above can only be speculation on my part. Anyway, good to keep the aging brain exercised ;o) Cheers Neil On 18/05/20, 21:14, "Daniel Kerr" <wamug.org.au-wamug-boun...@lists.wamug.org.au on behalf of wa...@macwizardry.com.au> wrote: Hi Neil / Matt I think sometimes it can be “OS” related as well, as each OS works differently sometimes. For myself, I can’t say I’ve come across this issue…..and in fact I just tested it now. My laptop is UserID 501. Running 10.14.6 Mojave On my wife’s iMac, I just created a new account for me (same username and password), and it has UserID502. It’s running 10.12.6 (Sierra). I just shared in to “my” home folder from my laptop. Form Finder it loaded fine, and when I copied and moved folders and files from my laptop to the iMac, and via versa as well (from iMac back onto my laptop Desktop and into other folders). All the files and folders copied correctly with no permissions errors. Everything opened correctly and didn’t say anything about owner permissions issues. (Even though the iMac thinks I’m 502 and my laptop is 501)….. But yes,…I think it previously could have some issues. Some of also can be Apple is (or did) move away from AFP file sharing. They then went to SMB1 sharing,…to be more “Windows friendly” and then recently (I think) if I remember correctly they went to SMB2 as it’s more secure. So by default sometimes these different protocols don’t always play well together. (I might have my terminology slightly off, but from memory it’s something like that. On another system I had to run a Terminal Command to re-acticate “SMB1” to file share with an older windows computer for a client). Sometimes if the “shortname” is different, it can cause some network file sharing issues, but that’s where adding in aliases works for that. But generally as long as the shortname is the same (and password), I’ve found they share fine,…even with different UserID numbers. Either that or I’ve just been lucky enough to always get it working,…lol. Sharing is always an “interesting” thing to work through sometimes. Different factors, different OS’es,…..always something :) Hope all this info helps Matt and you can get it working.
