GUID or APM for PPC and Intel Macs

Apple Article 306932 states
Click the Options button.
Select a new partition scheme:
Use "Apple Partition Map" partition scheme if the disk will be used with Time Machine and a PowerPC-based Mac.
Use "GUID" partition scheme if the disk will be used with Time Machine and a Intel-based Mac.
So, I have a PB G4 (PPC) and a Mac Book Pro (Intel), both of which I want to use with TM to one external drive.
So, which partition scheme should I use?

I suggest that you take a look at the following links as they may provide you with an answer :

External hard drive for both a PPC and Intel Mac?

I have 2 LaCie Hard Drives (500GB & 750GB) that I'd like to use for backing up my 2 laptops and for storing photo and music files.
When I got the MacBook Pro, I partitioned the 500GB drive into 3 volumes and used SuperDuper! to make "bootable" copies of the MBP on one volume, theiBook on one volume, and put photo files on the third. I don't know/can't remember how I dealt with the directions below from Disk Utility and I fear I may have done the impossible or at least done the wrong thing.
"If you will use a volume as a Mac OS X startup disk, click Options and choose the appropriate partition scheme. To use a volume to start up an Intel-based Mac, choose the GUID partition scheme. To use a volume to start up a PowerPC-based Mac, choose the Apple partition scheme."
As I ask these questions, I find myself getting tongue-tied so please bear with me and read on...
#1 - Is it *even possible* to do what I want and have the bootable copies of both of these laptops on the same HD since one is PPC and the other Intel? If the answer if yes, it's OK then the rest of this is moot.
#2 - I can easily delete one or the other laptop backup from the 500 LaCie and put it on the virgin 750 and partiton it - problem is, is there a way to know how I partitioned the 500 HD so I won't have to redo it -I don't want to have to recopy the thousands of photo files already on the HD. If I knew how it was partitioned - Intel or PPC - I could just delete the appropriate laptop and move it to the other LaCie, assuming I have to.
#3 - And, is it possible to use a drive that has been partitioned for PPC or Intel with the other type computer - will I be able to access the jpg photo files from both the MBP and my G4 both of which are Tiger no matter which way the HD is partitioned? Now I as able to do this, but as I said, I don't remember which way I partitioned the HD - all I remember is that I did choose to include OS 9 drivers since I still use Classic and OS 9 on the G4. ( I have yet another LaCie that I use exclusively to back up my G4 and it is not part of this issue)
Mrs H

So "To use a volume to start up a PowerPC-based Mac, choose the Apple partition scheme." really means it will work for my Intel MBP too?
Yes.
Is there a way to tell if that is what I already choose?
Select the existing drive in the Disk Utility and find the Partition Map Scheme text at the bottom of the window.

Partition scheme for PPC and Intel

I have a G4 mini and an Intel Macbook and one USB harddrive to back them up with time machine. I think I'll connect the drive to the mini and share the drive so I can back up the Macbook.
Anyway, I was reading:
http://docs.info.apple.com/article.html?artnum=306932
and it says to choose the "Apple Partition Map" scheme for use with PPC and "GUID" for use with Intel. Anyway, I was wondering what I should choose when I need to use it with both processor types.
Thanks for any advice!

Oops, it seems that a similar message appeared while I was posting this one, so I think I might as well just follow the discussion on that thread, sorry for the duplicate.

Antivirus Software For PowerPC AND Intel Macs

Thanks to the following instructions posted on MacFixit.com, ClamXav works on both my Macs (one G4 Powerbook and one Intel Imac):
"Hello, I have gotten the PowerPC version of ClamXav working with very little issue and works perfect from my test. To get it running, launch it normal and let it bounce for 10 seconds. After that, force quit it and on the program, right click or hold Ctrl and left click and then click show package contents. After that, go to contents and then resources and run 'clamavEngineInstaller.pkg'. After that, run as usual."
Google "ClamXav Intel MacFixit" to find the instructions.
Download ClamXav at www.clamxav.com.
It is freeware but I found it well worth donating to.

Welcome aboard Jany,No need to get your panties all bunched up about running Windows on your Mac...The beauty of running Windows on the Mac is even if the windows partition does get zaped with spyware and virusus it won't and can't jump over to your os10 partition...If you think about it why surf with the windows side when you can use Safari or Firefox on the Mac while running your Windows apps at the same time?
There area few percautions you can take to put yourself at rest, first make sure to always let Windows updates install themselves if you are going to surf the internet with Windows....also use Microsoft Defender which IMO is a great spyware program. Make sure that you have a router which does block unwanted incoming traffic or just do what I do and turn off your internet connection on the Windows side,that will guarantee no spyware or virusus.
Im sure many people will have more suggestions for you and Welcome to the world of Mac's.

Internet Sharing for PPC and Intel based Macs

I have OSX 10.4 Server running with NAT and DHCP enabled. The internet is accessed through a wired connection, and 2 Powerbooks(PPC based) and an Intel iMac and MacBook connected to the server via Airport. The wireless signal is WEP protected, and the Intel based Macs can connect to the wireless network, recieve a good IP address and access the internet. These two connected computers can be seen on the Server Admin DHCP Clients tab.
My problem is with the PPC based Mac, the 2 PowerBooks. Those computers can connect to the wirless network, but they get an invalid IP address. Not only is the IP invalid, so is the Subnet Mask.
All computers are running 10.4.7, and all installed from the Combo Updater.
Any suggestions?

We're having the same problem here!
Rarely we manage to get the right IP address assigned to one PPC machine by playing with various network settings but we didn't found a reliable way to get the PPC machines always working.
This is really strange... any suggestion is appreciated.

Is Target Mode universal across PPC and Intel Macs?

A new Mac Mini Server (2010) finds drives from recent Intel MBP, iMac and MacPro computers booted into target mode but does not see anything from a titanium Powermac G4 in target mode. Identical cabling: Mini > Firewire 800/400 adapter > firewire 400 cable > Powerbook.
Any thoughts or references to documentation?
Thanks,
John

Thanks for all suggestions!
The PowerBook G4 is the 867 (Ti) model: ATA drives. The host Mini (2010 Server) sees nothing when attached to the PB booted into Target mode.
The KB article that was suggested (HT1661) lists computers that support Target Mode including "Powerbook G4 (all models)." But under Requirements it also says "FireWire 2.3.3 or later." In System Profiler on the G4 on the Software>Extensions screen it shows me "IOFireWireFamily version 2.2.5." Is that the right place to look? There's also IOFireWireAVC and IOFireWireIP, both with version numbers like 1.x.x. If the Firewire version is too low, how does that jibe with the statement that "Powerbook G4 (all models)" are supported?
No firmware or system updates are offered by Software Update.

Does 10.4.6 have two different install CDs for PPC vs Intel?

Does 10.4.6 have two different install CDs for PPC and Intel?
Also, is only CD 1 required for OS install?
Thanks!

I tried my black OS X 10.4.6 CDs on a G4 yesterday specifically to see if an install from disk 1 only is possible. Sadly it is not. It requires about 400 GB from disk 2 no matter how minimal you try to make it. My disk 2 contains the following and the install needs everything except languages:
AdditionalEssentials.pkg
AdditionalSpeechVoices.pkg
AddressBook.pkg
Automator.pkg
BrazilianPortuguese.pkg

Have you considered upgrading to Leopard? Here is my general upgrading advoce:
OS numbers and names
OS X 10.4.x - Tiger
OS X 10.5.x - Leopard
OS X 10.6.x - Snow Leopard
OS X 10.7.x - Lion
OS X 10.8.x - Mountain Lion
More about Macs
The Apple History site has specifications for every Mac ever produced: http://www.apple-history.com/
Upgrade to Leopard
Those wishing to upgrade to Leopard should be aware that install disks can be expensive unless you contact Apple. Details: http://lowendmac.com/deals/best-os-x-leopard-prices.html Standard Leopard installers impose several hardware limitations including speed and RAM size but all these restrictions can be overcome. Google for details. Leopard works well at 500 MHz with 1 GB of RAM and many happy users have less than this.
Upgrade beyond Leopard
OSs beyond OS X 10.5.8 require an Intel processor. If in doubt check this: Click the apple at the top left of your screen and select 'About this Mac'. This will give you your OS number. Then click 'More Info' to see which processor you have. If it says PowerPC you cannot upgrade to Snow Leopard and above. If you have an Intel Mac it is well worth upgrading to Snow Leopard now and then considering other options after that. You can buy Snow Leopard here: http://store.apple.com/us/product/MC573Z/A

Universal CINs? (For MacOS 10.4 and Intel Macs)

Hi!
1. I was wondering if it was possible to build a Universal CIN for MacOS 10.4, in order to support Intel Macs. If so how? I get link errors in Xcode because it cannot find CIN functions such as MoveBlock, and NumericArrayResize when compiling for i386 (which is understandable). Is there an Intel Mac version of liblabviewcin.a and liblvexports.a?
2. Is it possible for LabVIEW to call a DLL function in a Universal framework? Or must all frameworks be for the PowerPC?
Thanks.

I am trying to invoke code external to LabVIEW that contain AltiVec and in the future, SSE instructions. Right now I am trying to bundle PowerPC code (with AltiVec instructions) with Intel i386 code to support both PowerPC and Intel Macs using a single binary.
So basically I have:
1. A CIN that uses AltiVec currently (which includes AltiVec instructions). I would prefer that it switched to a SSE version automatically when I call the CIN on an Intel Mac.
2. Some VIs that uses the Call Library Function Node to invoke a function in a Universal Framework. The framework is compiled for both PowerPC and Intel. The PowerPC version includes AltiVec instructions and thus is incompatible with Rosetta. I was wondering if LabVIEW would actually be able to invoke such a function successfully on an Intel Mac. I don't have an Intel Mac on hand, which is why I am asking.
PS: The original post was posted using NI JT's account accidentally. The question is actually mine.

Can PPC and Intel OS's be on the same hard drive?

I do a lot of work on Apple computers for clients.
I have made it a habit to bring firewire hard drives with OS X installed to my work locations so I can boot peoples' computers from my own, clean OS for numerous troubleshooting purposes.
I was hoping to take a big hard drive I have, partition it into 4 parts, and install 10.4 Intel, 10.4 PPC, 10.5 Intel, and 10.5 PPC.
But after I installed the PPC 10.4, I went to my macbook pro and tried to install 10.5 Intel.....and it wouldn't let me!
So now I am learning about the Apple Partition Map format for a drive versus the GUID format and that basically one is for PPC and the other for Intel.
But I would like to know if there is any way to format a drive in such a way that I can indeed install PPC and Intel version of an OS onto one physical drive in separate partitions???
anyone?

It's not intuitive but it's possible. You must set up your external drive using the APT partition map. Install the PPC version of OS X on one partition. Now here's the trick: You must install an Intel version of Leopard on a drive that has been partitioned using GPT. Then clone that installed version to another partition the external drive that now has the PPC version of Leopard. You now have a PPC version of Leopard on one partition and in Intel version on the other partition. You will find you can boot an Intel Mac from that partition even though the drive is partitioned APT.
The problem is that Leopard will not allow itself to be installed on an APT partitioned drive. But an Intel version of Leopard will work just fine from an APT partitioned drive.

Partition type for PCC and Intel??

Ok, getting very confused!!!
I have a PowerBook G4 which will have leopard installed next week. I'm also in the process of ordering a intel imac which both machines will be kept in sync using Chronosync.
I have a Iomega 500Gb firewire 800 hard drive that I want to use for time machine and clone backup, however, what type of partition do I use that will support booting both my PPC and Intel machines if the worst happens?
From what I can gather APM will boot both machines, is this right, does it have any disadvantages over GUID?
Thanks

The theory is that one leopard system can boot both PPC and intel. The problem is that the Leopard install can only be installed upon an APM disc by the PPC machine. Theoretically, if you do your Leopard install onto a firewire drive from a ppc machine, then it should be dual bootable.
Your theory about cloning the leopard install disc is not suitable since it does not include the various "application support" necessities and other appropriate pieces specific to your apps including iLife. Tis one reason that they say that you will need to reinstall iLife 08 if you don't do an upgrade install.
theoretically, you could boot both from an leopard system installed by a ppc machine onto an external firewire drive. You cannot install the intel leopard via intel except to the gpt/guid format. Also, you can boot an intel machine from an external USB drive but you cannot boot a ppc machine from an external usb drive. (already tried to install Leopard to a USB drive and I failed, Leopard install will not install from ppc to usb, but will install from ppc to firewire.) Firewire boots either intel or ppc and thus can be installed from either.

Difference in sound between Logic on PPC and Intel (64 Bit)

hi,
I'm using PPC for Logic Pro. Is there any difference in sound between using logic pro on PPC and running it on Intel Macs. I'm not good in tecnical things, but someone told me, Logic would sound better on Intel based Macs, because the system is 64 bit instead of 32 bit on PPC. Is that true? Any experiences?
Thanx,
grooveX

There are no differences!
the "sound quality" is stryctly relted with the Audio equipment.
(the new Intel Xeon processors are faster than PPC... in 2008... obviously... but in 2003/4/5 PPC G5 was much faster than same year 2003 Intel Xeon release
If you work with DAE TDM HD accell in PPC or on Intel the sound will be the same...
obviosly if some update shoot down the compatibilty with PPC side you will cannot use the future upgrades...
if you use a Motu 828 Mk3 the sound will be great... and same as ppc or Intel or Windows and Linux
(but Logic works on Mac... PPC and Intel... is the same... logic is the master of the sound).
Anyway... I think the analog recording studio in the 1970 1990 gives you a super great sound... in some cases the analog recording studio sonds much better that digital studios..
I'm talking about a simple example.. the audio frequency are from 20 to 20.000 HZ... the music quality... (artistically) is not related with the quality of the machine that you use for make it....
I suggest you not follow the mode ... and run to buy the last model .. most often are money thrown to the wind.
if you buy a good new interface.... you are in the rigth way...
but the very important thing is:
MAKE YOUR MUSIC AND DON'T MATTER ABOUT these unnecessary competitions ... is only useful to those who sells computer!
I know people that doing good music with old G4 ...
...music with highest quality ...
is not the machine that makes the music .... Only MEN can obtain a piece of art ... even using dirt!

GUID or APM? For two different Mac OS X - PPC and Intel?

I need to backup two Mac OS X systems for just in case situations. These two systems have to be bootable with the respectively Macs.
I intend to partition a spare FireWire hard disk into two partitions.
First partition will be for an Intel-based MacBook Pro.
Second partition will be for a PPC-based Mac mini.
Should I partition the hard disk either in GUID or APM? I know GUID is for Intel-based Macs and APM is the older partitioning scheme. I guess I can't have one GUID partition and the other APM.
After partition, I will use Disk Utility's Restore feature to clone my old Mac OS X systems to the respective partitions. And hope they will boot with my two Macs.
Help? Advice anyone?

NikonScan v4 and Intel Mac

I'm looking for people that can verify if NikonScan version 4, a Nikon Scanner, and an Intel Mac can play nice together.
Nikon says Intel Core Duo Macs are unsupported. What about the Core Solo? It's not mentioned. That doesn't mean it won't work on an Intel Duo or Solo and I'm just looking for verification either way from people that have actually tried it.
Nikon's Official Answer-
http://support.nikontech.com/cgi-bin/nikonusa.cfg/php/enduser/stdadp.php?p_faqid=13865&pcreated=1139239488
Currently Nikon products and software applications are not supported on Macintosh computers powered by the Intel Core Duo processor. Compatibility and support for Nikon products and software with Macintosh computers powered by the Intel Core Duo processor is currently under review by the Nikon Quality department. At this time we do not have any time-tables regarding when we will or if we will issue drivers and software support for this new system. Rest assured that Nikon will make every effort to support all the latest technologies developed by Apple and Microsoft. Keep checking our Knowledge Database system for updates regarding this issue over the upcoming months.
Someone in another Apple thread claims he uses NikonScan v3.0 on an Intel Mac. ->

THANK-YOU!
(2) B & W G3/500 & Gigabit G4/1.6 Ghz Dual Mac OS X (10.4.6)

I answered this one myself.
Yes, a Nikon LS-5000ED scanner with the USB 2.0 interface works with an Intel Duo Core 1.66 Ghz Mac Mini - 512 MB RAM.
Using the latest NikonScan 4.02 software and OS X.4.6 with all the updates.
No problems yet.
Hopefully the Universal Binary version of NikonScan will be available soon as I think it could run faster. Especially after Apple stops making the PPC models later this year.

OS X 10.4.x on PPC and Intel having problems with Card Readers

Hello,
I am in charge of a school district running about 75 client macs, all PPC G5 and Intel mixed. I have been having reports that the Lexar card readers for the digital photography lab sometimes do not auto-mount the media that is inserted into them. Apple System Profiler detects the card reader, but when the card is stuck into the reader it does not appear in finder at all to retrieve the files.
Upon testing, a reboot usually alleviates the problem, but the teachers feel that the interuption in class and productivity time for a reboot is unacceptable.
I have the user accounts managed through Workgroup Manager on my Xserve, and I have it set so that they have access to auto-mount media (unless I'm missing a setting somewhere. But i'd think if the setting was off, the reboot wouldn't matter and it wouldn't fix the issue).
At anyrate, my question is has anyone else expierenced problems with card readers and auto-mounting the media in OS X? How about in a multi-user environment. Does anyone have any suggestions? All are welcome.
Thanks so much for your time.

Since the latest update Mac OS X 10.4.9, my USB card readers have stopped working. The media is recocognized, but the transfer rate is so slow I could manually write the binary.
There were no issues prior to this update, and card readers work on machines NOT updated.
