    Apple ACE Enterprise case submitted.

    Still no sign of standalone updates for Catalina and Mojave Security Updates, over a week after their release. Has Apple stopped providing standalone updates altogether?

    Hello iMac!

    Through the glass window of an Apple Store, seven iMacs in silver, yellow, orange, red, purple, blue and green are seen sitting on a white table. “iMac” is written on the glass above the display. It is night time and the store behind the iMacs is empty.
