Hello Everyone I recently became the owner of a 2011 11' Macbook air, it has an i5 with 4gb of ddr3 Ram, the only issue however is that it overheats on Maverick, Yosemite and El Capitan even just running simple games or applications, so it is pretty useless unless you want to use it strictly for Halo (Which oddly runs fine at a cool 130-140F, Compared to a youtube video at 150-160F), Anyways i think ive finialy figured out the problem which is the logic board (My guess is that there is some corrupted part that fails to thermal throttle it, any ways i was thinking about the good old days when I originally got into macs and ppcs and how i saved up my money and bought 4 g4 macbooks and would find all kinds of fun applications and games that would only run on them, Seeing now they are all gone i was wondering if i could turn this obviously more powerful macbook air into a ppc that could run leopard and ppc applications.

Thanks for the advice

Every PowerPC CPU that ever went into a Mac runs far hotter than what came in the MacBook Air. If the Air is overheating, there's something wrong with it. There's absolutely no possible way to do what you would like to do here.

What do you mean by "overheating" ?

You checking Temperatures and considering "wow this is too hot !" or the MacBook Air actually warning you about overheating and eventually shutting down ?

Also, If you plan to use any MacBook for computing intensive tasks, you should put it on a table and make sure the vent are clear, so that it can cool itself efficiently.

About "turning your MacBook Air into a PPC laptop", I assume you don't mean actually changing your CPU and your whole computer architecture. (Like asking how can you turn your PS4 into a Wii U).

There is probably a PPC emulator for OS X (since it isn't included in OS X anymore) somewhere on the internet that would let you run PPC apps. However, don't expect good performances from it, especially since you are looking for games.

not super hot but the system log says it overheated so.......

I've had overheating problems with a number of Macs. It seems if it has a screen built into it, it tends to overheat. I had a Macbook Pro that had to go back to the Apple Store four times for overheating issues. My iMac still overheats quite consistently thanks to what is probably a busted heat pipe. I've also read online that a number of Mac laptops throttle down when presented with heavy workloads. On the other hand, units I've had without a built-in screen (PowerMac G4 & G5, Mac Mini) seemed to have no problems keeping cool.

I don't think you understand anything about the difference between Intel and PowerPC Macs. As you can plainly see in your triumphant screenshot above, your MacBook Air still has its Intel Core i5 processor.

"Converting to PowerPC" would involve replacing all (or most) of the innards of the machine, with an entirely different CPU. Plainly, you have not done this, and I don't think it would be possible (unless you custom-fabricated almost every related component).

10.6 was only ever released for Intel Macs; the last version to run on PPC Macs was 10.5.

You are conflating real PowerPC Macs (those with G3, G4, or G5 processors as far as ones that can run OS X) with Intel Macs running a version of OS X that supports software emulation in order to run PowerPC applications, a.k.a. Rosetta. Rosetta is in 10.4-10.6, thus by installing Snow Leopard you now have the ability to run PowerPC apps.

Why you would want to do this is beyond me. It will not solve your overheating problem for the simple reason that any kind of emulation invokes a substantial processing overhead, meaning that to perform the same task in a PPC app vs. an Intel-native one, it will place a greater load on the CPU.

OP:

What you're asking CANNOT BE DONE.

You CANNOT "convert" an Intel Mac into a PowerPC Mac.

With the appropriate software (up to and including 10.6.8) you CAN run older PowerPC-based software on Macs with Intel hardware (through "Rosetta").

But the apps you are running, are running "in software" -- NOT hardware.

There really isn't much more to say about it... ;)

IM NOT USING A VM, 10.6.8 is installed directly to the 2nd partition of my ssd , It can run PPC apps and its a form of Leopard That is what my purpose was , not to take out the CPU of a PPC and solder it in a MBA

I like Snow Leopard and it created a challenge for me ......

No, you didn't.
It can run PPC apps which is what i was trying to accomplish by converting it to PPC
[doublepost=1464117251][/doublepost]If i made it run leopard would everyone be happy that its a PPC

Humph.. Your title and wording clearly tell most people that you have somehow put a PPC CPU into an MBA. The video clearly shows that you are running on an INTEL I5 cpu. All that you have accomplished is to get Leopard to run on an MBA.

10.3 and we can talk.

Officialy, Unofficialy PPCs can run 10.6 look it up
Nooooope.

Re-read my (and others') post above. You are clearly confused.

Well done on wrangling Snow Leopard onto hardware that doesn't officially support it - but I still can't fathom why you've done it, unless you're just that attached to AppleWorks ;)

Read my original post my goal was to install an os that would Run PPC applications (like snow leopard ) and i did

My Bad I forgot, I was thinking of how you can Leopard on Intel Machines

mmmK so how else am i supposed to read this, "the last version to run on PPC Macs was 10.5." ;)
How to Run Snow Leopard On PPC
http://www.insanelymac.com/forum/topic/295199-powerpc-kernel-for-snow-leopard/
:rolleyes:
If you watch the video to the very end i explain why i like PPC so much ;)
The video you posted is a Core 2 Duo inside an old G4 iMac Case....look at 2:29 Processor...in the About this (computer) Mac

For the "how else am i supposed to read this, "the last version to run on PPC Macs was 10.5." ;)
How to Run Snow Leopard On PPC means exactly that if you have a PPC processor you can only run UP to 10.5...pretty simple!

Oops sorry my bad in class and dont really have time to watch to the end just look up running Snow Leopard on a PPC it does actually work, back in the day i did it on my Powerbook 11' G4

It is at the beginning!!!
Sorry but no, as stated by others Snow Leopard simply does NOT have the code to run on PPC as it is Intel only (Both Officially and Unofficially), if you really did, either you had a prototype PowerBook or a dev version of Snow Leopard (both unknown to men so far and would be worth a lot of money!!!!).

SL simply does NOT have PPC instructions.

[doublepost=1464188511][/doublepost]So if i did this everyone would be happy :) Seeing how im still in school and all Im not planning on doing something like that and why should I i already completed my Goal which everyone said wasnt possible

Some posts I've read in the past on this forum can occasionally be confusing, but rarely one as confusing as this - and even more so, your follow-up replies.
From your post #1, your goal was clearly stated, "turn this obviously more powerful macbook air into a ppc" (forget the part about running Leopard and PPC applications) these would have been bi-products in succeeding.
In trying to convince yourself that you've succeeded, in fact you've deluded yourself, arguing your case totally unsuccessfully against those who state one thing clearly i.e. it's IMPOSSIBLE to convert a macbook air into a PPC.
Also linking to videos (that you've not even fully watched, and certainly not understood) is not only misleading, but imho somewhat insulting.
And if that wasn't enough, in a very immature, over-smug statement in post #21, you finally shoot yourself in the foot in saying, "i already completed my Goal which everyone said wasnt possible", could have been penned by a Monty-Python script-writer!
Your goal as stated was to turn your Macbook Air into a PPC. This cannot be achieved.
It sounds as if you are young, and have a lot to learn, so please listen to the sound advise that good-meaning and knowledgeable folks here are telling you. You can't fool them, but are deluding yourself.

-"i was wondering if i could turn this obviously more powerful macbook air into a ppc that could run leopard and ppc applications." The rest of the post was just backstory i guess, not trying to confuse anyone i just wanted to figure out a way to run PPC apps without a VM and thats what i accomplished i wasn't talking about Physically converting it, i was referring to converting by modding the os or software.....

You should prob rename the title of this thread, as to me (and obviously everyone else) it sounds like you are trying to physically convert your MBA from an Intel Mac to a PPC Mac, which you cannot do. This very confusing to a lot of people.

There seems to be some confusion here...

"Converting MacBook Air to PPC" != "Converting MacBook Air to run PPC Apps". Yes, you got Snow Leopard (not Leopard BTW) to boot on on your mid 2011 Air which I didn't think was possible, and Snow Leopard has Rosetta for PowerPC emulation on an Intel CPU. But that does not convert your MacBook Air to a PowerPC!
