    What timing, just bought a new MBA for my daughter that came in this afternoon. Checked for updates and got this 10.15.5, but was confused since my Mac Mini is running 10.15.4, now I know why.

    I installed it, but I don't see the Battery Health function. I went to Sys Prefs/Power Saver, no new button at the bottom as I have seen posted elsewhere. Is there a place to turn it on (the button, I mean, the button is supposed to turn on/off the function).

    Interesting the this comes hot on the heels of my recent post in iOS and Apps called "Optimised Battery Charging" an optional setting for the iPhone.
    The post lists a number of do's and don'ts, mostly thanks to Randy, for maximising the health of Li-Ion (Lithium) batteries.
    I just checked for the update which was not there this afternoon but it is now.
    I'll get back when an if I find the button.

    Aha, I just read the linked article and then went to the linked article in that and there I read that the feature for battery management is only for Mac Books with Thunderbolt 3 ports. See

    Nice find Rod - just updated my early 2015 MBAir and according to this Apple Support Article, going to System Preferences > Energy Saver is suppose to show the screenshot below - well, mine looks the same as in previous macOS versions - of course, I've got an older laptop w/ TB 2 ports - assume the explanation? Not sure what these new TB 3 ports have to do w/ what is describe in the link given? Dave

    Here is the article I found this morning on the topic. See the fourth paragraph down.

    No sooner had I posted, osMac 10.15.5 appeared. I don't have automatically download checked, I prefer to do it manually, like to see what's happening. Perfect upgrade, no problems whatsoever.

    It is definitely a function on my wife's 2018 MBP just updated today. I'll check I over the next few days just to see if I can notice any changes.

    Just read an article in "9to5Mac" about backups made from Catalina 10.15.5 using CCC won't boot the Mac. I don't use CCC, I use SuperDuper so I tried it and the result is the same. During the copy process it shows the clone being made bootable, but booting from it fails.

    This wasn't a Mac with T2 chip where you need to set permissions to allow booting from an external drive. It seems Apple may have added a nasty security "feature".

    Just read an article in "9to5Mac" about backups made from Catalina 10.15.5 using CCC won't boot the Mac.

    I have 10.15.5 installed and use CCC.

    Just tried to boot from CCC and it worked ok. In fact it's a while since I tried booting from CCC but, if anything, it actually seemed to boot quicker.

    Just read 9 to 5 Mac and the following is important:-

    existing backups are unaffected, and this has no effect on CCC’s ability to preserve your data, nor any effect on the integrity of the filesystems on your startup disk or your backup disk. The impact of this bug is limited to the initial creation of a bootable backup

    This link explains all:-

    If you create a brand new CCC backup on a new drive, it won't boot, according to CCC. However, continuing to use a previous CCC backup will boot. And even if you do create a new CCC clone, it can be made bootable.

    From the blog at Bombich:
    Early last week we discovered an APFS filesystem bug in a beta of macOS 10.15.5. The technical details of the bug are laid out below, but the short version is that we're no longer able to use our own file copier to establish an initial bootable backup of a macOS Catalina System volume. To be very clear – existing backups are unaffected, and this has no effect on CCC's ability to preserve your data, nor any effect on the integrity of the filesystems on your startup disk or your backup disk. The impact of this bug is limited to the initial creation of a bootable backup.
    He then lays out the process to "fix" this issue:
    If you're running 10.15.5 and you're backing up a Catalina system volume to an empty disk, then you should replace your copy of CCC with the CCC 5.1.18 beta. After you open CCC 5.1.18:

    Click the X button in the Destination selector box to clear the destination selection
    Click on the Destination selector and reselect your destination volume
    CCC will then present new UI that will guide you through the procedure of creating a bootable backup, or if you choose, a Data-only backup instead.
    He also sort-of admits the problem with CCC is his own fault for not following Apple's suggestions:

    Last year at Apple's Developer Conference, Apple suggested that backup software should use Apple's "Apple Software Restore" (ASR) for cloning APFS volume groups. Initially I dismissed this – I shouldn't have to use Apple's black-box utility to do my job, I prefer to take full responsibility for my backups.
    By not following Apple's guidance, he ended up with a broken product. We've heard that story before...

    Good information Jake. I beta test for CCC so I do in fact have their latest version 5.1.18 beta 1. I did notice that after the installation of 10.15.5, that the CCC backup took twice as long as usual probably because it created a new recovery partition.

    It also appears that the no bootable problem was not limited to CCC but also to SuperDuper. Mike Bombich is a very diligent and knowledgeable developer and I trust that he will correct things with a future release.

    I actually didn't like Catalina and downgraded back to Mojave. Catalina wouldn't run some of the programs I had installed. It also seemed to slow down my iMac. Wasn't easy but everything is fine now. Sometimes I think Apple is starting to act like Microsoft too much with all these upgrades.
