After I updated my home server to 14.5 SMB became unstable. I was receiving huge lags (from a Linux client) and was unable to browse shares on my Mac clients (from El Cap to Mojave). Finder had trouble enumerating number of items within folders, up to the extent of showing 0 items inside a populated folder or even becoming unresponsive.
Fixed this by disabling SMB packet signing, this worked only after I turned off file sharing altogether and then rebooted:
Code:
sudo defaults write /Library/Preferences/SystemConfiguration/com.apple.smb.server SigningRequired -bool FALSE
Note that the above command is geared towards MacOS Server, if you are not using Server but just plain file sharing, it should be:
Code:
sudo defaults write /Library/Preferences/SystemConfiguration/com.apple.smb.server SigningRequired -bool FALSE[/instead]
Perhaps this helps somebody with similar issue.
Sadly, this didn't work for me here (I changed both files as I have server on here, but typically don't use it right now, but use the Mini to serve my whole house media system, which mostly consists of devices running KODI (FireTV and NVidia Shield) and various AppleTV units (one gen 2 unit,one gen 3 unit and one gen 4K unit). It freezes every 18-19 minutes in KODI now while playing a movie (used to work fine in El Capitan). You have to exit and start playing it again and it then starts freezing up again 18-19 minutes later like clockwork.
I just upgraded my 2012 Mini to Mojave 10.14.5 from El Capitan and instantly I'm having SMB issues with my NVidia Shield running KODI Krypton. The server pauses or is having some kind of difficulty from what I read and that causes KODI to freeze up. It's absolutely
unacceptable behavior from macOS and the weird thing is that hardly ANYONE online has noticed or is talking about it. This is one of the few threads I've found along with another one that claims Apple is aware of the problem (which apparently only did this specific behavior as of 10.14.5 (10.14.4 apparently did not) and they "claim" they will fix it in the next update, but god that could possibly be MONTHS away. So in the meantime I'm supposed to just not use my video library with KODI in my home theater? Ridiculous.
The only solution I can think of is to take my external backup and put El Capitan back on the drive (or boot off the external backup for now and hope it has no issues as it's the only backup I have of it). That's a shame because I had some serious problems with Mojave I don't want to go through again (i.e. I upgraded my Mini to a 2TB SSD and when I turned on trim support it wouldn't be any longer. I had to create a Mojave USB recovery stick and run disk utility first aid and then it still wouldn't boot (even with a manual terminal 'bless') until I used the Apple startup selector from the recovery stick (with no instructions anywhere on the Earth to explain this sort of issue despite reading god knows how many threads on trim control, etc.). Why add Trim? My ~500MB/sec write time dropped to 120MB/sec after 'upgrading' to Mojave. Once it booted finally with trim turned on, it's back up to ~500 again (oddly the Windows 10 Boot Camp partition I created just before upgrading to Mojave worked fine during all that).
Also, SmbUP no longer appears to work with Mojave (I tried re-installing it; NADA). You'd think that given Apple has largely abandoned AFP that having a really good SMB implementation would be a priority for Apple, but it has never worked in ANY version (outside Samba with SmbUP when it worked) like a Windows SMB. In KODI, you can't just select the SMB directory. You have to make a manual pointer to the local location instead (e.g. SMB://192.x.x) and then the directories will show up. The Mojave install also disabled NFS once again (you have to go in with a recovery partition and turn off the system protection thing to fix the file name that it resets when you upgrade or it won't work at all. It's hard to believe that OS X Server actually used to directly support NFS and now Apple does everything in its power to make sure your networking doesn't work right AT ALL. No wonder Windows users hate Macs.
Now that I have Windows 10 Boot Camp installed, I'm actually tempted to Network off it instead, but of course my media drives are on HFS+ formatted drives so I'd have to either get an extra drive and copy them over to another filesystem one at a time back and forth OR buy a program to let Windows read HFS+ (since after all these years Apple and Microsoft still can't agree to talk to each other's filesystems properly. The Mac can READ NTFS, but it can't write to it without some extra program (which I bought Tuxera, but that doesn't help on the Windows side to read HFS+ media volumes, let alone when Apple goes all out with APFS in the next version of macOS).
Such a PITA to just run a media server.....
