I have a macBook Air and an iMAC, both from mid 2017 and both running Catalina through the 2022-003 update. Over the last 2 to 3 months it has become increasingly common for Software Update to hang with a spinning gear icon and the message “Checking for updates”. The problem is especially acute on the iMAC. The only time I have access to it is late at night and for the last couple weeks I can’t can’t get past the spinning icon. I don’t check every day but have checked a large handful of days and on a day that I do check, I sometimes check several times within the space of an hour.
I’ve managed to install the 2022-004 security update on the Air, but not on the iMAC.
My overall question is how do I install an update if Software Update doesn’t work?
Is there something similar to the MS Update Catalog where I can download a security update and then install it?
Is anybody else seeing the hanging behavior in Software Update?
My internet research hasn’t turned up anything useful. Everything just says to open Software Update and go from there.
Thanks
