I updated my Mac to 10.12 Sierra and updated Pages, Numbers and Keynote afterwards to the latest versions.
So far so good, everything running normal.
But unfortunately saving a Numbers file via AFP on a local Synology NAS (DS1815+, latest DSM) caused the application to crash and kicked all connections to shared folders.
Saving on the local HDD is no problem at all.
Then I tried to figure out whether thats a single problem with AFP and killed the AFP file service on the NAS to only start the SMB2 service.
No problem to save on the NAS via SMB.
I tried to save a numbers document on the NAS via AFP from another Mac. This time with an older version of numbers (3.6.2) but on a freshly updated macOS Sierra and it causes the same crash of numbers and all connections to the NAS.
Therefore: It seems to be a problem with macOS Sierra and the AFP server of the current Synology DSM (6.0.2-8451 Update 1).
Is anyone experiencing the same issues? Does anyone have a suggestion for a workaround?
Thanks a lot.
I think it might be a problem with the versioning of the applications which use file versioning. Someone described the same behavior with Preview while saving a JPG image. And I could reproduce the same crash with my Macs.
