I thought I would share a problem I recently came across after upgrading one of my Macs to Ventura 13.2
I use an M1 MacMini as a server that hosts my 2 Promise raids. After the OS update, the SMB share broke. (Very slow connections and hanging) The issue is related to custom icons (which I didn’t even know I had).
Anyway, for a better explanation of the problem and a fix see this article.
