If anyone is afraid of updating to 10.15.5 inadvertently (like I am), the following Terminal command will block the update:

softwareupdate --ignore "macOS Catalina 10.15.5 Update"

Now getting this error message, which I don't recall getting before:

Ignoring software updates is deprecated.

The ability to ignore individual updates will be removed in a future release of macOS.

Supposedly it won't work on a computer this "old". Good thing people have mentioned the Al Dente app here, which is much better than Apple's implementation, since you can actually control the charge level (what an alien notion, having control of your own hardware!)
Yeah, same here... I was excited about this feature, but it sounds like it maybe won’t be as useful as I first thought. So, i went the Al Dente route instead, with which I can leave it set to 70% for most of the time (since I, almost always plugged in), and releasing it to charge to 100% when I know I’ll need it.
 
That reminds me of what we had to do at work, back in the Snow Leopard days.

The Snow Leopard update was not free, and due to some quirk or issue they were not able to sell us a bulk license, so we had to go ahead and order a few dozen retail copies to upgrade our department Macs. The big stack of 30-something boxed Snow Leopard install discs arrived soon after.

Since we only had to buy the copies for software licensing reasons and could upgrade everything using OS imaging, only one of those discs ended up being unwrapped. We still have the stack of Snowmeow discs, all shrinkwrapped, in a cabinet somewhere. What a waste.

I'm so glad Apple finally made the upgrades free. They already make plenty on the hardware and services!

I loved Snow Leopard. I'm still waiting for Snow Catalina.

al dente? i only knew http://dosdude1.com/catalina/ . Got some quirk also, air play not work,side kick not work(macbook pro early 2011)
 
Don’t hold your breath.... I’ve had this issue at least since Mavericks :oops:

I have never encountered this issue. I checked with several coworkers and they haven't encountered it either (we're all still on Mojave). Maybe there is some other factor involved with that.
 
This still doesn't fix the issue with copy large amount of data to an external Solid State Drive. I can easily copy data to an external spinning disk hard drives, but when copying to an SSD, after a GB or two, the whole system will freeze and reboot. This is happening on both a 2018 MBP and 2018 MBA, but both have T2 chips. This is beyond frustrating as their are literally files on the SSD that I can't get off.

I'm usually fairly lenient on Apple, and have tolerated many of their missteps and lack of QC recently, but this issue is really, really pissing me off. I can't tell you how many crash reports I've submitted to no avail.

I'm just hoping that whatever macOS 10.16 is called it won't be the dumpster fire that Catalina has been.

using external ssd 2 boot.. i can try now if work.. no crash on imac 2017 baseline

Apple has abandoned us Sierra users(i have my reasons)



whats the science behind this? Why I shouldn't use 100% capacity of the battery?
what about plugged in which reaches 100% all the time.

100% battery means the battery stays at a higher voltage which speeds up battery degradation. IIRC, Li-ion batteries are happiest at 50% to keep voltages low but it's not really practical. 70% is probably the best trade off between battery degradation and daily usage.

this new macOS battery management feature keeps batteries under 100% even when plugged in. if you really need 100% everyday, you'll turn this feature off.

I had to relaunch Finder the other day because it was frozen. Good to know it's potentially not just my machine.
 
I believe it is related to the T2 chip, which the 2017 iMac doesn’t have.

I'm SO glad I've so far avoided getting Macs with that infernal T2 chip. It seems like this chip has brought nothing but headaches without really adding any useful features.

Why the heck does Apple think they need an entirely separate CPU in Macs, running its own operating system? Could they not see this would add another point of failure and instability in the system? Unnecessary complexity is the enemy of reliability!

Yeah. I know.
It’s a six year old piece of vintage now, I guess.

sorry dear, if my macbook early 2011 die then i will think again buying. Now stick to imac 2017. Yeah a bit scary each day when heard terminator chip.

But this is not “The Science”. To quote a previous poster: “lol zero science in there, just a load of talking.”

You must donate further time looking up scientific papers that the OP probably won’t have access to, and even if he did, might not have the background required to read them, just to assert something that is as well known as Newton’s laws in physics for those who ever read the scientific literature on Li-Ion batteries.

All to appease a random self-righteous poster on an Internet forum who, if he is truly so concerned about this, could have linked to “The Science” himself, but thought it better to just complain about others who decide to help to the extent they consider appropriate, given that they are doing this for free.
 
Update seemed to go fine, but /var/log/system.log is reporting issues with mds:

May 26 23:23:30 mycomputer com.apple.xpc.launchd[1] (com.apple.mdworker.shared.08000000-0600-0000-0000-000000000000[703]): Service exited due to SIGKILL | sent by mds[114]

I updated three computers to 10.15.5 - and one to 10.14.6 - and the same line is repeating on both over and over and over - like 4 times per second. One of the computers was a fresh install of 10.5.5 (downloaded tonight onto a USB - then nuked and paved the computer), the others were regular updates.
 
I experienced apps insist on opening after logging in despite unchecking the "Reopen windows when logging back in" option. It's annoying. Is it fixed on this update?
 
Anyone else pissed off that the MacBooks that can most use this battery management right now, older ones, don't have the feature?

I know Apple wants us to upgrade our hardware but at least don't be so blatant about it.
Agree. I've just bought a MacBook Pro 2012 non-retina. Upgraded to SSD & 16GB RAM. Lovely machine but would have really benefited from battery management.

I think those battery health measurements are kind of approximate. Mine sat in the high 90s for a long time and then dropped rather precipitously into the mid-80s.

It’s not that they are approximate (which they indeed are, but not in the sense you’re talking about here). They’re a snapshot of the battery capacity at that moment in time; they’re usually good enough to predict the runtime for the next discharge cycle (unless of course you store the battery for years before the next cycle), and even then, it depends on how quickly you discharge the battery, on temperature and so on.

However, chemical changes within the battery are not a linear process. Over time it will lose capacity and there isn’t really a fixed %/year or %/cycle figure you can count on; these figures vary over the lifespan of the battery, and quite often the final degradation is especially quick.

I had a mid-2013 MBP whose battery started noticeably degrading after about 5 years, and over the span of a few months, it died completely (literally not enough to take the charger off the wall and quickly, i.e. one second later, put it back again). So again, it’s not a linear process.
