Question: How can I stop the update message for High Sierra
Every week I get a message that I can update to High Sierra. It is annoying as I can't just click it away but have to open the App Store to keep the message away for a week.
I currently run MacOS sierra and use two programs that are incompatible with High Sierra (Filemaker 11 and QuickSync). At least Filemaker won't release an update. They rather sell me a newer version of their program for a few hundreds of euro.
