  1. “macOS Catalina 10.15.6 Supplemental Update Beta”

    We used to chide Microsoft for its stupidly long names. Now it seems Apple is getting as bad or worse.

    And, is this beta software that only the risk takers should load or is it really for the average user?

  2. Dear all, since the last updates was installed on my Mac which have in the moment macOS Catalina 10.15.6 that working on several sites using Safari that the PC becomes very slow, as an example watching a video on Facebook book it’s impossible because he crash. What I can see on Activity Monitor is that the amount of running process/app’s they don’t justify the Memory Used. With a total of 8Gb of memory, since the updates the Memory used all the time it’s around 85%, doesn’t matter if there 10 process or 40 process. Does anybody have any suggestion?

  3. How about naming it 10.15.7??
    Even idiot users can tell support people the version installed in the “About this Mac” window. But supplemental update? Yea, have a user confirm that for ya.

    1. This is the second update to 10.15.6 so far … it appears that Apple don’t want to give macOS a .7 update.

      It would make much more sense just to have a 10.15.7 update with all the recent fixes in it.

    1. Don’t install a beta just for fun. If you’re not prepared for problems that won’t be resolved for some time, then betas aren’t for you. Apple recommends that you never install a beta on a device used for primary work. If you have a secondary computer, then install it on that. But if you only have one computer, then wait for the official release.

      ‘This is from someone who has done official beta teasing for decades.
