Hi all,
nothing to do with Indigo/HomeAutomation: on my iMac (it is not the Indigo Server), mid-2013 I have since weeks frequent spinning beach balls.
Disk Utility found nothing; EtreCheck (this a tool which is used also on Apple Support Forum) says disk is failing. It is an old 5400rpm disk, and maybe this is also the root cause.
During Christmas holiday I replaced failed disk on a late-2006 iMac and it was really simple, but on the "slim" iMac I would not take the risk.
I plan to install macOS on an external USB3 SSD (no FireWire, and Thunderbolt enclosure are too expensive).
What do you say about?
