    Rather small update at almost 3GB?? Not to mention Apple makes little effort to define exactly what changes are involved to take up almost 3Gb of download. I am one who feels Apple should dump the once a year Mac OS upgrades and focus on stability. Big Sur has mostly been yet another train wreck and were still downloading these big updates. All the closer to Monterey release.

    The link to the IPSW download of the macOS 11.5 update just jumps to the top of the article. And there’s no link to instructions on how to install the IPSW, just a sentence on how difficult it is. Could you fix the link and provide instructions?
