Apple has released macOS Catalina 10.15.5 Supplemental Update

Apple has just released a Supplemental Update to Catalina 10.15.5, which includes an important security fix for a kernel vulnerability and a small update to the BridgeOS firmware for models with a T2 chip. The update is around 1.5 GB, but contains no other significant changes apart from:

Build version updated to 19F101 with new kernel;
Re-installation of the MRT 1.61 update from last week.

A standalone updater is now available from here for 10.15.5.

Security Update 2020-003 for High Sierra has been revised and released again (available from here), but there’s no update for Mojave.

I have now updated the firmware version database used by my free SilentKnight to reflect the change in BridgeOS version.

Per your note on macOS prior to Catalina, my MacBookAir4,1 running macOS 10.13.6 High Sierra received another Security Update 2020-003 today after the one with the same name on May 26th.

  Thank you – yes, it was only T2 models which got a firmware update, and that is the BridgeOS part.

another Mojave bug, worsened.

Using Mojave and: apple mail and finder unresponsive, stall, freeze after 2020-003 update. To be honest since switching to Mojave from Sierra, this bug has been there a while but it’s worse now, longer in duration, and now I have to force quit mail.

There are just times when I can’t get mail to respond — to allow me to highlight an email, get back into anything with mail after tabbing over to another app or the finder. If I cmd-tab from safari back to mail, safari remains in front of mail even tho mail appeared in the cmd-tab strip of active apps.

I have to force quit Mail and restart to get it to let me back in. Anyone having similar issues?

FWIW
Thanks Howard.

  Thank you. I’ve just seen someone else report similar problems after installing the latest 10.15.5 Supplemental Update, which didn’t alter Mail or anything related. So this might just be coincidence. Have you considered resetting permissions on your ~/Library folder?

Hi Howard and friends, a few months back I go so fed up with Catalina updates clobbering my network settings that I developed a bunch of bash functions to run at login which check and restore my settings when required. I upgraded my 16″ today and the scripts failed to restore my configuration because the networksetup utility now requires sudo to do these things. I haven’t been this peeved for quite some time…

The only problem I notice with 10.15.5 and the Supplemental Update so far is that if I double-click my Apple Watch 4 on request to wake my MacPro6,1 from sleep or to enter the login password during use like unlocking preference panes, it also pops the dialog box and I have to enter it manually making the Watch redundant. I turned the handy function off by unchecking the the Securtity preferences box but I can’t get it to re-pair with the Watch. I also had a devil of a time getting my Apple BT trackpad to re-pair with my MacMini7,1. I suspect something has gone awry with the Bluetooth function in 10.5.5 or Supplemental Update.

  Thank you. Pretty well the whole of Bluetooth support was replaced in 10.15.5, so that may be to blame. Time to contact Apple Support, perhaps?

    Just to follow up, before notifying Apple Support I re-installed macOS 10.15.5 using the Combo Update and re-installed the 10.15.5 Supplemental Update on my MacPro6,1–no joy. Then on the Internet I found a frequently suggested workaround for previous macOS/IOS’s (BTW a problem I never had until 10.15.5) of turning off Handoff in my iPhone 11 (iOS 13.5.1) Settings>General>AirPlay & Handoff, pairing the Watch (WatchOS 6.2.6) and turning Handoff back on. Thankfully, that worked.
