PPC (power PC) & Intel

Hi! I'm new to Mac and I just wanted to find out what is the difference between a PPC or Power PC and an Intel Mac?

What Allen Eckert said. In addition...
PPC and Intel chips use different instruction sets which is a fancy way of saying that programs written for one don't work on the other. However, Mac OS uses something called Rosetta to, if necessary, translate PPC instructions into Intel instructions. So if you look at the list of installed Software in "About this Mac" you will see that each is labelled with one of PPC, Intel or Universal. Universal means that the program is actually two copies, one PPC and one Intel. An Intel Mac runs the Intel version and an older PPC Mac runs the PPC version. A program labelled Intel means that it specifically uses the Intel instruction set and will not run on a PPC Mac. And PPC (Microsoft Office Test Drive for example) means that it was written for a PPC Mac but will run on an Intel Mac via Rosetta, which is less than ideal but not bad.

Problem with Java app on Mac OS X... works fine in PPC, not on Intel

Hi all,
I'm at a loss... I've always been under the impression that java is the same no matter where it's running, but I've come across something that surely counters that line of thought. At work, we use a java application from DTI to publish our newspaper. This app works just fine on Mac OS X 10.4.x on PPC Macs, but the same application doesn't work on Intel Macs, also 10.4.x.
The app launches and appears to be working fine, but there's a point where it must download some support files from the server. This is where it breaks with the error:
java.io.IOException: null, com.dtint.macutils.AppFile.decode
The corresponding entries in the console log show this:

If there are any other logs I can provide, let me know what would be helpful and I'll get them.
I've got no clue why this wouldn't work across platforms unless it was compiled for the PPC processor or something, but then wouldn't it either launch in Rosetta or not at all on the Intel? I'm a systems admin, not a programmer, so I've really no idea where to start looking.
What I have done to this point is made sure I'm on the latest Apple-released Java, as well as copied the Java files from the PPC to the Intel to see if there was something there. Nothing makes any difference.
This would be a major coup if I could get this working... does anyone have any thoughts or ideas about getting this to work?
Many thanks in advance!

Opening PPC songs on Intel macs

Hi everyone,
anyone had problems when opening PPC songs on Intel macs? specialy large music scores causes intel logic to crash...
best.
intel imac 20 Mac OS X (10.4.7) 2Gb RAM
Powerbook 17 1.33 G4 Mac OS X (10.4.6) 1Gb RAM

hi andre, look up this topic here. justin c, has written about it, i think.
he recommends "rebuilding your autoload" for starters.
if these songs crash logic, you might have to do a fresh autoload and import all the files and start from scratch. bad, i know.
file corruption seems to be at the bottom of it all.
i have trouble just editing something in 7.2, and then running it in 7.1.1.! and i'm using the same mac for both.

Power Managment in PPC vs. Intel Mac

I had a question about power management. Previously I have used a Mac Mini PPC for a home server. Everytime my power would flicker, the Mac Mini would bring itself back up.. (I had marked Power up after power failure in System Prefs). But now, since I have had the new Intel mini.. if the power flickers, it may, or may not come back up.. depending if the power flickers quickly. I am guessing this is b/c the BIOS is different in the new Intel Minis... but I would figure Apple would have it behave the same... but it flat out doesn't.
Any suggestions?

Well, I was just presenting a single case. We actually have 100s of these mac minis in the field that we do not have physical access to. A UPS would solve one of the problems, but not all. The solution that Apple previously had in place where the Mini would start up whenever power was applied worked great for us. But in this case we need to get something that would either do that, or allow us/user to turn on the mini without physical access to it (its locked up). Any other suggestions?

Hi All,
I would like to know if there is a possibility to build the indesign plugins once for both PPC and Intel on MAC. Right now I'm forced to build my plugins twice: on the PPC machine and on the Intel Machine.
I tried to build the SDK example Basic Persist Interface on my MAC Intel machine and then i placed it on my MAC PPC and it failed to load.
is there any configuration I need to specify so the XCode linker will link for both machines?

How do I remove migrated PPC apps from Intel iMac that has the same apps?

Before I begin, please know that I've read a lot of previous posts but all the posts only had some of what I needed so I'm posting this as a new topic. OK, here I go:
My PPC running 10.5 just froze-up (that has since been solved) but in the process of solving that issue, I migrated everything as a different user (User B) INCLUDING my applications, to my Intel iMac - my iMac that also had the same applications on it - except they were intel versions and they were under User A.
So I essentially did an archive and clean install on my PPC.
Then, using Migration Assistant, I transferred User B onto my PPC. Now both of my computers have duplicates of most of my applications. In trying to fix this issue, I found out I should NOT have transferred my applications. So now I'm very confused as to which apps I should remove off my PPC and which I should remove off my intel iMac.
If I just delete User B from my intel iMac, that's easy enough but will that remove the dupes? I have a funny feeling it doesn't.
And then, which do I remove from my PPC?
AND THEN, are there other things I will need to remove from different places on my computer?
Any help would be greatly appreciated. Thanks!
And now, I've used migration assistant to move everything from user (B) back to my PPC. Now I have duplicate applications with "(from old mac)"

Normally application go in the Applications folder at the top level of the hard drive, not in any user folders. If you have applications in user folders that are the same as those in the Applications folder, you can delete them from the user folders. If you actually migrated PPC applications into the Applications folder on an Intel Mac, it would have replaced the Intel versions. To fix that,you would have to reinstall OSX on the Intel Mac.
The same thing would apply on the PPC Mac.

System Image for G5 (PPC) and iMac (Intel Core 2 Duo)

hello,
I would like to know if there is a way to create a common system image Mac OS X 10.4.10 that I can "deploy" in out two mac labs. One with G5 (PPC-based machines) and the other with iMac (Intel-based machines).
If yes, how can I do that ? with a script ?
I tried to boot a G5 with image made on IMac and it didn't boot...
Anybody can help me ?
Thanks a lot for your cooperation,

Welcome to Apple Discussions!
As they are not comparable versions of Mac OS X, a dual boot configuration would be needed. One with a GUID (for Intel) formatting, and one with Apple Partition Map (for PowerPC). This Mac OS X hints page explains how to make a dual boot configuration:

Transfer Library from PPC to new Intel iMac

I have an older G5 running iTunes 10 (latest) and am getting ready to buy new iMac that I assume will be running iTunes 10. My question is if there will be an issue transferring the library from the PPC version to the Intel version, even though they are both iTunes 10. My library is really big, around 300GB, because it contains movies, etc. I don't have room on my PPC HD to create a back up before I transfer the library. Will it be safe if I keep the PPC around for a couple weeks while I migrate files over? I'll have the same issue with my iPhoto and iMovie libraries. Thanks in advance.

Hi Chris,
Thanks for the note.
I wouldn't have asked if I didn't already look at that.. I would do it in a second - unfortunately, there is no sense of real control here - for example, if I'm migrating mail, does it migrate all my messages? Just my password/account settings? I don't want my mail content. I can easily set up the password/account settings by hand. Should I? I don't know.
I don't want to migrate all apps... I want to migrate iTunes.
I don't want to migrate all users... just me.
But... I am not willing to start poking "ok" and keeping my fingers crossed in hopes that I won't have to go through an hour of work to undo what I should have had the choice to avoid in the first place.
This may all be speculation, but it wouldn't be if the process was clear, or stated "all or nothing" - but it doesn't, at least, as far as I can tell.
The Apple site has little that really helps either:
http://www.apple.com/pro/tips/migration.html
I sure don't mind doing things by hand - I've been doing that for 20 years. However, I do mind -undoing- things by hand.

Going from a PPC to an Intel Mac

Will OS 10.8 Mountain Lion support PPC apps (those I've been running on OS 10.3 up to 10.5.8 Leopard)? I think they will run also on OS 10.6 Snow Leopard, but can't confirm until I have an Intel Mac (needed to run OS 10.6). If OS 10.8 will not support them, will OS 10.7 Lion? I Know that 10.9 Maverick will not.

Thanks, Lyssa for your reply
A good portion of the software you're running probably has an Intel-compatible version at this point.
That's true, except for one really important CAD app I need. My CAD app (Canvas X) was no longer upgraded for Mac starting about 2007. It has been upgraded only for Windows. I think this is about the same time that Mac completed its switch from PPC to Intel, which most likely explains the unwillingness of my CAD company to upgrade. I'm reluctant to attempt running a Windows CAD app on a Mac, using Bootcamp or Parallels.
Much better I think is to get the latest MacBook that will run OS 10.6
Try running Canvas X in Snow Leopard Server installed into Parallels for use in Mavericks.

Can you convert a ppc to an intel

I have a
Power Mac G5 (late 2004)
Model M9555LL/A

is there a way to convert it to an intel pc so I can upgrade everything to current levels, or do I look at a new intel power pc?

Share external hard drive between PowerBook (PPC) and MacBook (Intel)?

Hello.
I recently purchased an HP Portable USB 3.0/2.0 1TB external hard drive (http://j.mp/f9FP4M). I'm trying to figure out the best way to format it so that my girlfriend and I can both use it. Problem is, I have a PPC-based PowerBook G4, and she has an Intel-based MacBook. Hopeless?
If not, here is the ideal scenario:
--One partition that can boot Tiger (I still have the CD).
--A second partition that can boot Snow Leopard (just got it for my girlfriend).
--A third partition where my girlfriend can back up her MacBook using Time Machine.
--A fourth partition where I can back up my PowerBook using whatever means possible/necessary.
Can someone please suggest how I might do this? I would be very grateful for any assistance.
If any part of my ideal scenario has to be sacrificed -- I would not be at all surprised -- then let's forget about my PowerBook and focus on how to format the drive for her MacBook. I presume I would just need to do GUID, but I'd still need guidance on how to create partitions to boot Snow Leopard (and Tiger, if that would still be possible).
Happy to clarify any of the above if it's unclear or incomplete. Thanks for reading and for thinking this through with me!

Move pair of 1 TB HDs from G5 PPC to new INTEL Machine?

I have had a workhorse PPC G5 for many years, but software upgrades demand I graduate to an Intel-based machine. Can I simply move the two 1TB Hard Drives from the old machine to a new one or are they incompatible? They are both about a year old.

They are compatible, but the partitioning map or tables (Apple PM) are not and need to be reformatted to GUID is all.
Better in FW case until you copy files you need and reformat before using internally. With 4 internal bays, you'll still have one free.
And skip Applications during Setup (or Migration) Assistant step and you should be fine, and then do fresh installs and avoid having to redo later.

Can't Import Mail From PPC Mac to INTEL Mac

How does one import the mail folders from a PPC G4 system to a new Intel Core Duo system.
1. I've copied the mail folder from the G4 to an external Hard Drive.
2. I then connect the external Hard Drive to the Mac Mini Intel Core Duo.
3. I open MAIL on the Intel system and tell it to import the mailboxes from the external Hard Drive.
4. All of the mailboxes import, but contain no mail.
5. I then quit MAIL and restart it.
6. My IMPORT folder has disappeared and there are no imported folders, and no mail.
7. I've done this 6 times all with the same result.
Help Please. Has anyone successfully transfered mailboxes from PPC system to the new Intel system? If so how?
THX,
X86-1138

Hello all,
Thank you for your help, but I figured it out on my own.
Here is how I did it.
1. If you are moving "Mailboxes" you've created on a PPC Mac to an Intel Mac
you must have the Same Versions of OS X running on each system.
Please note that this is for people who are just setting up there NEW INTEL MAC and wish to transfer "Mailboxes" from the PPC Mac, and can not get the Migration Assistant to work.
If you've already created New "Mailboxes" on the Intel system they may be overwritten/replaced using this process. Resulting in the loss of any newly created "Mailboxes" on the Intel.
2. Be sure you have Tiger updated to the same versions on both systems.
3. On the PPC Mac, go to your Users/(your user name here)/Library/Mail folder.
4. Locate in the Mail folder a folder named "Mailboxes".
5. Copy the "Mailboxes" folder from the PPC Mac to an external hard drive.
6. Eject the hard drive from the PPC Mac and turn off the hard drive.
7. Connect the external hard drive to the Intel Mac and turn on the hard drive.
8. Wait for the external drive to mount.
9. Be sure that the MAIL application is not running on the Intel Mac, then go to Users/(your user name here)/Librery/Mail.
10. Look inside the Mail Folder. Do you see a folder named "Mailboxes"?
11. If yes, see step 13.
12. If no, see step 14.
13. Stop and I will try to post another solution for tranfering "Mailboxes" into an existing "Mailboxes" folder so you don't overwrite or replace your new "Mailboxes"
14. If you don't see a folder named "Mailboxes" in your Mail folder, do the following.
15. Drag and drop the "Mailboxes" folder you copied onto the external drive, into the "Mail" folder on the Intel Mac.
16. After all of the files have been copied to the Intel Mac, Start the MAIL application.
17. All of the "Mailboxes" you copied over should now appear in the "Mailboxes" list under your mail accounts list.
Hope this helps anybody else who has run into this problem.
Regards,
X86-1138

Yes, same issue here. Other apps are unaffected.
cpu ussage goes down when video is running but not displayed (like switching to another tab / app) or paused.
cpu ussage also increases/decreases with the size of the player on screen, so this definetely is some chromium rendering issue.

Later edit: Same issue with chromium-pepper-flash-dev... All similar bug reports are 'pending' (https://code.google.com/p/chromium/issu … ?id=338578).
The adobe plugin is not supported in chromium anymore, so we're stuck
Well even HTML5 videos (which do not depend on pepper flash, right ?) have higher cpu usage.
And I've got the same issue with Firefox (using the extra/flashplugin 11.2.202.359 package).
Weird, isn't it ?
According to the page chrome://gpu, it is somehow related to https://code.google.com/p/chromium/issu … ?id=137247 and https://code.google.com/p/chromium/issu … ?id=133828
