Frage: AFP Sharing not working
I want to share a folder via AFP. This seems to be impossible on my iMac (latest OS => 10.13, 17A405). I can enable the general "Enable File Sharing over AFP" (and SMB). However, I cannot access that share from my other machine (Mac Mini late 2012, latest OS). Sharing the opposite way from Mac Mini to iMac works!
If I ctrl+click on the respective folder in system panel sharing, I get the advanced options. Interestingly, the dropdown box is disabled / greyed out showing just "SMB" on the iMac, but not so on the Mini.
Any idea what's wrong with my system and how I can get AFP sharing back?
iMac (Retina 5K, 27-inch, Late 2014), iOS 11.0.3
