What’s the next video about?

He definitely caught the Krazy

but it didnt.....

Do you like when people explain a joke to you?

​​@@mikepxg6406that phrase made me giggle a bit, I killed 2 power supplies by testing shorted stuff without knowing it, that little phrase hit home so much I personally felt it

DosDude: "Hold my beer"

Why is that? Can you do anything with these?

@@Rollmops94 The OP would have been using the DTK for it's intended purpose not for a laugh and a giggle. The video explains what the usecase of these DTK's was.

@@adem1781 Thanks for nothing.

@@Rollmops94 the reason these were locked up is because they are the first ARM boards that could run MACOS, and apple is a jealous cunt and thinks they invented every technology that they copy from others

I had one also but as an independent developer and the process was much less threatening sounding. I originally wasn't even going to bother because it sounded like they had very few and were going to be pretty restrictive with who could get them, but a few weeks after they had started sending the kits out they sent a reminder email to developers that they were available and at that point I decided since they clearly weren't all gone I might as well try. I've never even published anything directly to the Mac App Store, I just gave them links to multiple apps I developed and they approved the application and sent the DTK. There was no special courier and the return was just a normal prepaid FedEx shipping label. It's pretty cool that someone was actually able to activate one of these several years later, I'm surprised they didn't disable that on the server side.

Wow that was stupid of them

@@YimYum911 probably the easiest way to drill into those packages - and since the checkmark "drilled" was reached, the intern doing it didn't care for doing more damage

Sounds like you beat them from their planned dumpster dive.

I don't understand why businesses do things like that. I found my own main PC in perfect condition in a dumpster similarly to this.

Company: makes functional prototype IRS: destroy that for tax money Company: how much? It's stuff like this which makes our society so wasteful and perversely incentivized

@@maverick9708 Tax office and legislature want taxes be paid, not avoided

Yeah, the point is that they genuinely won't derive any more value from them, but the IRS doesn't know that if they export them. Breaking them first is easier/cheaper than maintaining records of what happened to them

I also kinda object to another common feeling people express. These aren’t “perfectly good machines”. They are a low volume orphan with limited potential. The processor wasn’t an M1, it didn’t support all the important MSRs that the M1 had (some for instance might make Rosetta work better). It didn’t have the same number of cores in the same configurations, the peripheral interfaces were not the same as the M1. Apple wouldn’t want to support this configuration in a shipping OS. “But Linux” you say… sure, but what district would want to carry around support for such a limited machine? It isn’t a waste, it is just how development works, there are steps and often times the intermediate steps are simply limited usefulness. Historically significant, sure, and I am confident that apple saved a few examples for its archives. I am equally sure that somewhere out there some developers didn’t turn one back in (probably more than one maybe). Either that developer just forgot, or intended to give it to a museum so others can enjoy it, or simply keep it secret for long enough to sell it to a collector for a profit later. (Which sounds a little shady I guess)

@@jonqu7041 This is a fair point "Apple wouldn’t want to support this configuration in a shipping OS", but I still think it's very wasteful that they deliberately destroy them! If people want to use them, they should be able to do, apple can just be very explicit that they are unsupported. The fact that this is considered normal is a pretty bad sign of how our society works.

This right here

Depends entirely on where the damage is on the board. If it's through power rails, but doesn't affect any rails which are vital for basic functionality like in this case, you can just clear the damaged area and it'll work If the board's snapped in half and is multi-layer you're SOL since the traces under the surface layers can't be accessed to be rejoined without destroying the other traces above them. Same if the damage is more centralized, the board was drilled or the damage has occurred in an area where a lot of critical power and data traces reside.

It is possible to repair PCBs, including traces deep within a multilayer board. It just becomes more and more expensive to do, so it’s rarely worth the effort. Take a look at Pace’s “Adventures in Rework” video series. They demonstrate excavating traces, fixing them, and then repairing all the layers above them to restore the whole PCB.

I'm just in awe, that this guy would even try to repair that cut.

@@cathrynm it’s nuts. It takes courage I certainly don’t have! But I suppose, if it’s already broken, nothing to lose if you have a level of patience I also don’t have lollll

Maybe he could put Mac-OS onto M1, 2, ...& A11, 12, ... iPad PROs ? Truly gods work if this would happen, .. & build hacking community about such a process!!

@@johndfella1That would be a sight to behold. It would also make the iPads worth their crazy high prices!

Yeah, the soldering work alone, on those tiny components. Like he could do it blind. That would have taken me a week of trial and error 😅

I hope for your own sake you have backups 😅

​@@spicybaguette7706 screwdriver is his backup

I'd replace that hdd immediately

That's one way to get rid of a virus! 😅

So there were no traces near the hole, but it wouldn't respond, and after you made the hole bigger, it worked perfectly? That makes absolutely no sense.

Already did that actually.

That was kinda what I was thinking. This answers my question heh

Ok bro

This one is a two part screwing, The IRS for saying you can write its expenses off if you destroy it and apple for complying

they have to destroy them by law.

In the name of sustainability this shit needs to stop.

@@maverick9708 Imagine if I could write off my car as expense if I said it was a prototype and just destroyed it.

I agree with you, but that's not what happened here. They wanted to destroy these machines specifically because they were never supposed to be given to anybody but developers on a temporary basis. The fact they were dumb enough to trust some random Chinese recycling company to not resell them is funny though.

There are probably 1000s of these.

Drill the soc?

@@Rollmops94 yes but a guy with a hammer will sure have fun destroying these, i know i would

_They might, now._

They will, next week now that this video was released, and someone somewhere will get in trouble for not sufficiently disabling them - big companies like to pin their problems on some unfortunate schmuck somewhere, rather than managers take responsibility

I'm surprised as well, xbox and sony did this with xbox 360 and ps3 dev kits back in the mid 2000's. If they logged online they were effectively bricked.

@@jforce321same with the Xbox one x dev kits I believe

@@lordgamer0912 yeah they've all done it since then just mentioning how far back they started

Lol, perhaps it's a "feature".. i.e. if your software works ok on the DTK, it'll _fly_ on the actual device..🤭

@@mugwump-bk7os At work, we nicknamed Big Sur as "Bug Sir". Ironically, Apple accidentally put it as Bug Sir on a KB article until I used my connections to alert them...LOL. Big Sur on ARM was extremely buggy for the first few months.

It was for the sheer amount of power the silicon pulled on these DTK boards. Even with those batteries, it could still only last for essentially the duration these were available for. This was essentially an iPad chip working in a desktop form factor, and there had to be some way to persist the RTC upon power failures even if it really did guzzle through those coin cell batteries.

​@@FairPlay137 ah so the coin cells are basically replacing what would have been the original iPad battery that would have been used for keeping time.

@@FairPlay137 Oh okay that makes sense thank you!

Thank you for asking this question.. I had to shake my head at DOSDUDE for not even mentioning what the hell they were. Shame on him... and he's supposed to really teach us about these boards -_-

Wow ​@@FairPlay137

1. FDR server is only for syscfg data (not the same as NAND firmware). Though, I still have gotten dual-NAND working no issue on these, you can use NANDs from A12Z iPad Pro. You can also install blank M1 NANDs onto A12Z iPad Pro board, restore on there, then they also work on DTK (after programming correct serial number and such of course) 2. I absolutely intend to attempt to get later macOS versions running. If successful, I will be prepared for the future when they stop supporting M1. Hopefully that won't be any time soon haha.

@@dosdude1 Can you also test this with Asahi Ubuntu?

disagree with "crapple" (butchering company names is kinda cringe) but agree on everttyhign else

The three button cells are for the CMOS/PRAM memory because apple didn’t spend the time to optimize the power draw. Thus the three cells to keep it alive long enough for the time devs were using them

I would love this

Maybe on very early stage prototype devices with factory protection fusing, definitely not on a production device.

@@bemorewantless so would a lot of Mac users including myself if it was possible I wouldn’t hesitate in trading my two MacBook Air laptops for an iPad Pro 13 inch fully loaded

It's not that hard unless you really want lead free solder. After a few hundred components it's still fiddly but you'll get there.

I´m always so confused by comments like this. If you want a laptop get a laptop. Nobody who uses an iPad actually wants a window manager.

@@JonGretarB I use an iPad Pro and would love a much better window manager… I’m so sick of dismissive comments like yours i.e., “because I don’t do something means everyone thinks just like me!” Apple put the name “Pro” in iPad, they also gave it the Mac chip when they didn’t have to… they gave us proper mouse support, which once upon a time did not exist, in the m4 generation they moved the camera to the top of the screen like on a MacBook, they also gave us an excellent keyboard with function keys like a MacBook… it’s clear from the hardware perspective, iPad Pro pro is much more Mac like than ever before. Apple also gave us thunderbolt (with pcie tunneling), and the ability to connect to a monitor (with DisplayPort tunneling). These are Mac like hardware features. But the software is too limiting. Apple should bring macOS lite (with the traffic lights 🚥) and free form window management, possibly the ability to run Mac apps, the ability to use more than one audio source simultaneously. The files app should have the ability to unmount media and format media with no partitions (give us APFS, HFS, exFAT … just like on Mac). The hardware is already more than capable… the software needs its training wheels taken off and let power users tap in to the hardware. And just like stage manager, if you want to turn off the free form window manager and go back to ‘regular iPad OS’ then give us that option as well. I think Apple needs to stop presuming that only it knows best what the user shall be able to do with the hardware, and instead empower users to be able to use the hardware in a more open manner, similar to how it is on the Macintosh. The Macintosh is a great paradigm for what an Apple operating system can be.

No crucial traces in this area, luckily.

You probably bought this one, which I sold on eBay after filming this video.

It runs absolutely great. In fact I am likely going to daily drive one as my main machine it's so nice.

"Apple is gatekeeping iPads from MacOS so they don't cannibalize sales"

I mean the latest iPad has an M4 that is faster than the processors in most Macs, so the power was never the question.

I'm not deep into current apple lore. Do they have any hardware they ship w/ MacOS that supports a touch screen interface out of the box? Maybe MacOS w/ touch isn't exactly ready for prime time yet? But yeah, it also wouldn't make very much sense from a SKU marketing perspective, both from the sales cannibalism vantage point, and from the consumer confusion vantage point. The latest M4 iPad pro is at the very border of sanity in that regard.

Also, Macs can run whatever software you like, whereas iPads can only get software via the App Store - from which Apple get a cut.

Basically the circuitry that is responsible for the real time clock? Or nvram? Not really sure is not optimized at all and uses "a lot" of power when the system is off. So the quick fix was to tack on multiple batteries because it's a prototype after all and was designed to be returned after a few months. I read somewhere that even with the three batteries installed it drains them in a few months lol.

The SoC was designed for use in an iPad, which has a gigantic battery at its disposal to run the SMC/RTC coprocessor off of when the device is off. In that instance, the amount of power it draws is not an issue. The DTK doesn't have that, of course, so instead they added multiple coin cell batteries... Which even then, still die after 6 months.

​@@dosdude1Ah that makes a lot of sense. it was such a joy seeing you bring this back to life. Seeing that restoring software bar move along after all the trouble you went through... I am so glad this unique piece of hardware made it into the right hands. Thank you for persisting and saving it. And thanks for the reply too. That's hilarious that even with the added capacity of 3 batteries that it still only lasts 6 months 😆

Yes, completely self taught on soldering and hardware, and mostly self taught on software.

@@dosdude1 I've seen you on Luke Miani and always wondered. God-Like!

@@dosdude1 very good vid and specially that you explain every single small step. ❤ Easy to follow you, but it would be hard to do it by myself.

Many thanks for your great video!
