Apples Brain Trust Cache

The other day I was updating my M1 Apple Mac Mini to macOS Monterey and received a strange error. “Failed to load update brain trust cache”. Being that I write a lot of try catch blocks when programming, and know they rules I live under to make meaningful actionable catch error box responses, and what goes into providing users information they can actually use to handle an error, I was intrigued to find out what Apple was thinking on this one.

Failed is just a verb they used to notify that they catch was reached.

Load is another verb letting the user a file was attempted to be opened

Trust Cache is something that Apple uses trust files for letting the system run stuff at a platform privilege level. Meaning these cache files content are trusted by the entire computer.

Update brain is the logic that is tied to an update. Meaning the programming (the brain) so the update knows what to do.

So in other words, during the update, the local trusted cache needs to be updated, the logic that runs the update regardless if the update is on a watch, phone, ipad, macOS or whatever needs to be trusted at a platform level so it can run. So that local immutable read only cache needs to get an update before the system can update.

My guess is that 1) the apple update downloads to a computer 2) the update once started does a hash compare to make sure the update file has not been hijacked during transit to the computer that is running the update. To do that the hash of the update is compared with apple over the internet. If the hash checks out then 3) the local trusted cache gets updated so the update can run a platform level with out the user having to enter their username over and over again during the update.

In my case, what the error was telling me is that when the hash was being compared, the compare either failed, or more likely when the Update Brain was attempted to be opened as a platform level trust cache, that open failed.

What I did is click the button to start the update again, and the file probably called update brain was able to load as platform privilege storage as trust cache.

Browser Wars

So why would a company spend millions of dollars to develop and maintain a software application, then offer it for free to anyone who wants it? Why would Microsoft double down on efforts making it more difficult for users to switch their web browser to Chrome or Firefox? Something you need to understand about Products: You either buy a product or your are the product. And what does you earning Cryptocurrency, you and your web browser have to do with each other?

You have heard the term “Everybody wins”? well its kinda like that. Lets face it pretty much no one except a very small few could actually create a web browser. If you took for example the 250 million firefox users and the cost of annual development $50 million, you can see you would pay less than a dollar a year to use your firefox web browser. But since you sell part of who you are to firefox allowing them to sell that data, you get the web browser for free! Ya You, free $1 web browser, well done.

Joking aside, its a trade. You are trading a lot of information about you, what you like, buy, and are. For a web content browser that you don’t have to pay for. And Microsoft wants their piece of the pie back. Since people are creatures of habit, and most have the habit of using Chrome, then Safari, then Edge, Firefox, Brave, Opera…. Microsoft is trying to move up a spot by making the most popular operating system hard to change the default web browser. “Can’t win, cheat” I think is the motto that comes to mind.

In Windows 10 it was kind easy, you could change 1 setting and the only negative side effect is you are pestered with constant suggestion that you are doing it wrong and that you should try Edge. Well in windows 11, Microsoft went to a hole other level of truly devious proportion. You will need to change by protocol which browser you want to use. Thats right the protocol. And if you are reading this and are asking your self, what the hell is dot dot ping ping? you will probably be an Edge user with no escape. And Microsoft is counting on it.

The browser I think is fantastic is Brave. I am pretty sure they use the Chrome engine (don’t worry, dot dot ping ping) with a look that they created. They block most add’s, don’t sell your searching usage like all the others, and give you the ability to make money if you choose by getting a crypto called BAT for signing up to not block adds. Yep that is right, you can make money for the adds presented instead of 100% of that casholla going to the web browser company. Now that is closer to a win win agreed? The revenue Brave makes on you choosing to view and add last I check was split 70-30. Yep. you are the 30 and don’t tell you thought you would get it all. But before you run off and download and switch bot Brave because you want to start earning BAT crypto, do your research. learn about Crypt, know what a blockchain is. Learn how to use crypto to actually purchase something. Otherwise you have stuff on a screen that is useless. Know that crypto is still very new and there is a lot of changes happening and many opinions.

All in all, know nothing is free, self reflect and find out what you value, write it down. Find out what you don’t want to be, write it down. Yes a pen and paper. Do your due diligence and learn about the lake before you jump in the water, that stuff could be on fire, but maybe you like fire. Or maybe you like easy comfortable slow privacy phishing. At least you will be well known (to all the advertisers).

I hope this was helpful, maybe a little fun and scared you a little to. takes balance to be balanced.
