S/w from 33MHz to PowerPC 120MHz?

Hi,
I have a PowerBook 540 c modified to a PowerPC 120MHz processor. I have a wonderful computer game (called Capitalist Pig) originally purchased for my 33 MHz PowerBook 120.
Unfortunately, the game won't run on my PowerBook 150. Is there any way I can run this game?
Thanks.
BTW- next up is a Newton software install and how i wish Cyberdog was still around. Fantastic interface.

Thanks to those who have informed me about the 68K Mac Army Website. great Forum.

Import Mail from Imac G5 PowerPc Panther to Imac 8.1 Intel with Leopard

Hi,
I wonder if someone could be so kind as to outline the steps to transfer my mail and associated mail preferences (rules etc) from my old G5 PowerPC to my new Intel based IMAC. I'm a little unsure as I've heard various nightmare stories and also some rumour about emails not being readable once transferred across from the PowerPC based IMACS to the new Intel based IMACS.
My mail is extremely important so I'd rather proceed cautiously and correctly to ensure no loss of data.
Many thanks in advance
Q.

You can restore the iMac to initial condition with respect to Mail by removing the current Mail folder (Home/Library and locate the Mail folder) and the com.apple.mail.plist file from Home/Library/Preferences.
On the G5, first use Rebuild Mailbox on each mailbox before the next attempt to move the Mail folder and plist from the G5, while able to do so in Panther. Then read the following for background:
This happened a lot when people upgraded a single computer from 10.3 to 10.4 and Mail 2.x, but the issues are nearly the same if upgrading from 10.3 to 10.5, and much the same trying to migrate the Mail assets.
For background read the info in the topic at the link below, which while written about conversion from 10.3 to 10.4, would also structurally apply to a conversion from 10.3 to 10.5, even if using 10.4 in between. Sadly, it would appear the conversion process has not been strengthened, although the real fault lies with the condition of the mailboxes prior to Upgrade -- this is the purpose of making the index for each mailbox as healthy as possible before Mail tries to convert the structure on the mailboxes.
http://discussions.apple.com/thread.jspa?messageID=5664866&#5664866
In this situation the messages are not lost, but properly converting them for use in Mail 3.0 (or first in Mail 2.0) can be a detailed and tedious project. The best thing would be to have used Rebuild on every mailbox prior to the Upgrade. Of course I recognize that for those converting a single Mac it may be too late for that now, but you have opportunity to improve on that!
There is an issue often when going directly from 10.3.9 and Mail 1.3.11 related to conversion of the data in the mbox file into xxxx.emlx files in the Messages folder that Mail 3.x uses. The Messages folder came into use with 10.4.
An important comparison to make, after you know where to look in the Finder, is to compare the size of the mbox file in any xxxx.mbox folder to that of the Messages folder in the same mailbox. The reason to do this is check whether all messages that were in the mbox when the Upgrade was done were converted properly.
There can be issues if you ran a still earlier version of Mail, and other leftover files might then be present which could be problematic.
Please do not hesitate to ask any and all questions you need to ask to get comfortable with all you may need to do, depending on the number of large and complex mailboxes you had prior to the Upgrade.
If nothing else, be sure to read:
http://docs.info.apple.com/article.html?artnum=301315
which was mentioned the referenced topic.
Btw, if the Messages folder of any xxxx.mbox were to be near or over 2 GB all by itself there could be another problem called overstuffing.
Be sure to keep a copy of the prior Mail folder and plist available for further attempts if the next one does not succeed. The index structure has changed since 10.3, but in converting Mail can use the old form of one index per mailbox to the single universal index now called the Envelope Index. Using the old indexes and table of content info is what allows Mail to retain the relationship of incoming messages and replies to those messages.

Ok to move LR 2 presets and settings from old Mac PowerPC into my Mac Pro and LR4?

I had a Mac PowerPC but recently purchased a Mac Pro. While I was at it I got Lightroom 4. Now I want to migrate the Settings and Plugins folders from my LR 2, which is on the Mac PowerPC, to my LR 4, which is on the Mac Pro. Is that going to cause a problem?

Hi.
...My question is: Can I use the hard drives and RAM chips from the older Mac Pro in a new Mac Pro? I have a lot of money tied up in the additional HDs and RAM chips and I hope I can save money if they are compatible with a new "very basic" Mac Pro...
While your HDDs are reusable as Kappy said, be aware that the sleds they are in are not. The new Mac Pros use a different sled design so you'd need to take the drives off the old sleds and install them on the new sleds before you can install them in a new Mac Pro.
Also, you can get some good deals on the RAM you'll need here http://eshop.macsales.com/shop/memory/Mac-Pro-Memory#1333-memory.

Running pre-PowerPC apps

Hi,
I have a PowerBook 540 c modified to a PowerPC 120MHz processor. I have a wonderful computer game (called Capitalist Pig) originally purchased for my 33 MHz PowerBook 120.

The powerBook 120 was only released in Japan (when I was last here). In 1993 or 4. It was 33Mhz , black and white with no connection for an external monitor. Very basic but popular at that time. It was a toss up for the Apple PowerBook or a Compaq laptop with Win 3.1. Both very nice but i went for the 120 as it was lighter in weight. And there began my love affair with Apple
The later PowerBooks (150 c, etc.) released in japan became popular due to teh colour screen and J'nese friends were buying at extraordinary prices. My powerBook stayed with me til 1997 til a colleague wanted a laptop for simply typing his Masters thesis. I had pangs of regret ever since and a friend at a Mac Users Group event gave me his 540c which was gathering dust at home. It has been modified but I really wanted an original laptop again... and now I have dug out my old Hypercard stacks, my Newton , 3 Stylewriters, etc., I have this urge to set up a sort of mini studio in my office for students to experience early computing (and it's only 10 years ago or so!).
Hope this answers your query.

PowerBook 12 Mac OS X (10.4.2)

How do I upgrade from a 10.6.8 to a later version?

Trying to download apps from the App Store and keep getting the message that the app can't be installed on my system because Mac OS X version 10.7 or later is required. I have a 10.6.8. Doesn't an upgrade automatically get updated from Apple when I get the message on my Mac that updates are available? Do I download from the app store? There are so many choices - don't know which one to pick. I'm not a fully matured Apple yet - I'm just a bud and a lot of it looks like Greek to me.

Before embarking on a major OS upgrade, it would be wise, advisable and very prudent if you backup your current system to an external connected and Mac formatted Flash drive OR externally connected USB, Thunderbolt or FireWire 800, Mac formatted hard drive. Then, use either OS X Time Machine app to backup your entire system to the external drive OR purchase, install and use a data cloning app, like CarbonCopyCloner or SuperDuper, to make an exact and bootable copy (clone) of your entire Mac's internal hard drive. This step is really needed in case something goes wrong with the install of the new OS or you simply do not like the new OS, you have a very easy way/procedure to return your Mac to its former working state.
Then, determine if your Mac meets ALL minimum system install requirements.
To install Mavericks, you need one of these Macs:
iMac (Mid-2007 or later)
MacBook (13-inch Aluminum, Late 2008), (13-inch, Early 2009 or later)
MacBook Pro (13-inch, Mid-2009 or later),
MacBook Pro (15-inch or 17-inch, Mid/Late 2007 or later)
MacBook Air (Late 2008 or later)
Mac mini (Early 2009 or later)
Mac Pro (Early 2008 or later)
Xserve (Early 2009)
Your Mac also needs:
OS X Mountain Lion, Lion, or Snow Leopard v10.6.8 already installed
2 GB or more of memory (I strongly advise, at least, 4 GBs of RAM or more)
8 GB or more of available space
Next,
If you run any older Mac software from the earlier PowerPC Macs, then none of this software will work with the newer OS X versions (10.7 and onward). OS X Snow Leopard had a magical and invisible PowerPC emulation application, called Rosetta, that worked seamlessly in the background that still allowed older PowerPC coded software to still operate in a Intel CPU Mac.
The use of Rosetta ended with OS X Snow Leopard as the Rosetta application was licensed to Apple, from a software company called Transitive, which got bought out, I believe, by IBM and Appe could no longer secure their rights to continue to use Rosetta in later versions of OS X.
So, you would need to check to see if you have software on your Mac that maybe older than, say, 2006 or older.
Also, check for app compatibilty here.

If you have any commercial antivirus installed and/or hard drive cleaning apps installed on your Mac, like MacKeeper, CleanMyMac, TuneUpMyMac, MacCleanse, etc. now would be a good time to completely uninstall this apps by doing a Google search to learn how to properly uninstall these types of apps.
These types of apps will only cause your Mac issues later after the install of the new OS X version and you will have to completely uninstall these types of apps later.
Once you have determined all of this, you should be able to find the latest version of Mavericks by clicking on the Mac App Store icon in the OS X Dock and then login to the Mac App Store using your Apple ID and password.
You can then begin the download and installation process of installing OS X 10.9 Mavericks from the Mac App Store.

How can a mount a NFS share exported from OpenBSD?

Hello Apple Discussions:
I've been experimenting with NFS in a mixed OS environment, and have been successful exporting nfs share with tigerserver, and mounting it on both a powerpc linux system, and on a powerpc openBSD system.
Likewise, I can export a NFS share from the linux powerpc box, and mount it on the openBSD box and on the tigerserver, although, the latter required using the options (ro,sync,insecure) in my exports file.
However, when I export a share on the OpenBSD box, I can mount it on the linux box, but not on tigerserver.
I would like for the OpenBSD box to export a NFS share securely, with read-write permissions, to the tigerserver.
After reading so many tutorials, that it would be a page of links, just to list them all, I am pulling my hair out. However, I have found one thread that suggests, that perhaps what I'm trying to do is impossible:
http://www.bsdforums.org/forums/showthread.php?t=54308
Here it is suggested that the NFS won't work because tigerserver is not using UTF-8?
I will have to say, that I was somewhat alarmed, that the only times I succeeded in mounting an nfs share exported from linux onto tigerserver, it was when the "insecure" option is used in the /etc/exports file. There doesn't seem to be an equivalent for the linux style exports option "insecure", in the bsd style options of --maproot=user:group1:group2.
But I don't like using any options that say "insecure" anyways, so rather than trying to find out how to make openbsd "insecure", I would rather like to find out if there is a way to get tigerserver using UTF-8, at least when mounting NFS shares, if this is indeed the issue.
Here are the more technical details. I've created a user on all sytems named "fives" with the userid of 5555 and the groupid of 5555. I made the user local user in the local net info domain, but I've tried it with an LDAP user as well. The folders I wish to export and the folders into which to mount them are all owned by user fives and group fives, and have permissions set to 0775. The ip addresses are OpenBSD=192.168.222.111 TigerServer=192.168.222.233 LinuxPPC=192.168.222.253. I've included the relevant NFS setup files and running processes below:

# actually, I don't see statd, but haven't found the equivalent in openbsd. There's rpc.rstatd, and maybe it should be listed here, but there doesn't seem to be a way to launch it directly. This is a competitor with the UTF-8 theory about why it's not working.
ON THE TIGER SERVER:
# here's proof that tiger server sees the mounts:
showmount -e 192.168.222.111
Exports list on 192.168.222.111:

# here's the result of user fives' attempt at mounting a share:
sudo mount -t nfs 192.168.222.111:/exports/fives /imports/fives
mount_nfs: /imports/fives: Permission denied
# yet user fives has no problem mounting same share on linuxppc box.
What is different about OSX server? I thought it was supposed to speak NFS?
---argh... I'm steppin out for a pint.. Hopefully when I'm back it'll just work.

One thing not mentioned is that if you decide on the multiple user approach, you can have your music folder in Shared Documents so you only store the tracks once.
Each user is free to choose which of those tracks they want in their library.
There is an Apple help article on multiple users.

Can I use a PowerPC iMac as a monitor for my MacBook Pro?

I have an early 2011 MacBook Pro running Mountain Lion. I need an external monitor for it and have an old iMac laying around that I'm wondering if I could use. The iMac is the first gen white square all-in-one screen one. It's a G5, 20" 1.8 GHz from 2005. PowerPC.
Can I connect my MacBook Pro to it to use as a second monitor? Or even to mirror the display? If so, what kind of connector cables do I need to make this happen?

You need to use a product such as ScreenRecycler over a network connection. All of these products require the capability to boot the iMac.

How to update from Mac OS X 10.6.8 to Lion or all the way to Yosemite

I have a MacBok Pro running Mac OS X 10.6.8. How do I update to Mac OS X 10.7 Lion? Or if I go all the way to Yosemite, do I need to buy and download every Mac OS X between 10.6.8 and Yosemite? Are there any free (and legal) Mac OS X downloads between 10.6.8 and Yosemite?

You don't need to do any of the intervening versions but can go straight to Yosemite in the App Store.
This will of course prevent your Mac from executing any PowerPC code. So you should check to find out if you are using any apps coded for the PowerPC processor. If you have that it will need to be upgraded to a newer version coded for the Intel processor.

We need to upgrade from Leopard to Snow Leopard and then on up the chain. How?

We have an old MacBook running Leopard (10.5.8). Can we upgrade to Snow Leopard and then add others gradually untill we get to the newest version? If so, were can we find a copy of Snow Leopard?

Should I upgrade from OS X Lion (10.7.5) to Mavericks or Yosemite

I think I need to upgrade OS X (am starting to hit sites that tell me my version of Safari is not supported and indications are that I need to upgrade OS X)! I know Yosemite is the latest version, but the reviews in the App Store aren't encouraging me to take the leap. Can't find any reviews for Mavericks, nor the upgrade. Anyone offer me some advice?
Thanks.

JPG Image Icons imported from OS 9.1 stay tiny in OS 10.4.8 finder windows

The icons of nearly ten thousand jpg images that I transferred via AppleTalk from my old PowerPC (OS 9.1) to my new iMac (OS 10.4.8) appear tiny in finder windows. [The problem seems to be unique to jpg image files, since other transfered items, such as folders, documents, and tiff image icons, behave normally on the new system.]
I have no problem with new images that have been created or saved on the iMac; they behave properly, adjusting from 16x16 to 128x128. However, all old (transferred) images in the same finder window remain tiny, no matter how I adjust the settings in View > Show View Options.
I have discovered an unsatisfactory, tedious, image-by-image workaround. By opening a single old image and chosing "Save As…" I can save the image as a new jpg; then the icon will behave like other newly created images. Unfortunately, once the image is newly saved, I lose important data about the original image, such as Date Created.
How can I "update" the old jpg image icons (transferred from OS 9.1 via AppleTalk) so they will behave like the newer icons, without losing old image data and having to resave the images one by one?

you need to trash the current version of IPhoto, just the application, leave all libraries intact, throw te iPhoto into the trash and up date, it wil ask you after install what libraries you want to install. Your choice, latsest is always my chioce. Do all the iPhoto updates before this step, as the download could have been corrupted. Hapened to me on my wifes nachine 10.7.3., which would have been certain death for me. After the re-install it will ask you which library to install, I always pick the latest, but you can put in others as well.
Good luck, because if I lost those files, I'd be pushing uo Daisys about now.
There might be someone who knows a better wat too do this, and there is software to help ypu recover your data.(Data Resue, ClamEx)

How can i get an upgrade to IOS7, from IOS10.5.8?

I am trying to install a new garmin software and it says I need to update my software. The MAC OSX software update says no updated needed.

Before you do ANY major system updating OR upgrading, I strongly advise that you backup your current system, purchasing and installing/using either a high storage capacity Mac formatted USB 2.0 Flash Drive OR a large capacity USB 2 or FireWire 800 Mac formatted external hard drive and either use the included OS X Time Machine app to backup the data on your Mac's internal hard drive to the external storage medium.
Or you can purchase a data cloning app such as CarbonCopyCloner or SuperDuper to create an exact and bootable copy (clone) of your Mac's internal hard drive to the external hard drive.

Where can I download OSX Mavericks to upgrade from Lion?

I have an Early 2011 Mac Pro 17" and have just acquired an Apple TV - but hey presto Lion does not support mirroring - whereas Mavericks does!!
So short of upgrading to Yosemite (mixd reviews...!!!) I was hoping to upgrade to Mountain Lion or Mavericks??
Anyone know where I can get Mavericks from?
thanks

If you have never purchased OS X Mavericks before under your Apple ID, then it is no longer currently available.
OS X Mountain Lion is still available on the Mac App Store, but you must purchase a special email download code to download and install it from the Mac App Store.

So, you would need to check to see if you have software on your Mac that maybe older than, say, 2006 or older.
Also, check for app compatibilty here.

If you have any commercial antivirus installed and/or hard drive cleaning apps installed on your Mac, like MacKeeper, CleanMyMac, TuneUpMyMac, MacCleanse, etc. now would be a good time to completely uninstall this apps by doing a Google search to learn how to properly uninstall these types of apps.
These types of apps will only cause your Mac issues later after the install of the new OS X version and you will have to completely uninstall these types of apps later.
Once you have determined all of this, you should be able to find the latest versions of OS X by clicking on the Mac App Store icon in the OS X Dock and then login to the Mac App Store using your Apple ID and password and if you purchased a download code, input that code.
You can then begin the download and installation process of installing the newer versions of OS X from the Mac App Store.

I want to upgrade from snow leopard to Mavericks, but only Yosemite is available!!

How do I upgrade snow leopard to Mavericks on one of my older macbooks? I note that Mavericks is no longer available via the App store, only Yosemite, and I do not want the latter. My latest macbooks all have Mavericks pre-installed, and I want parity on all.

OS X 10.9 Mavericks is no longer an available, downloadable OS version.
You can choose to decide and download the free OS X 10.10 Yosemite OR pay to download either OS X 10.7 Lion or OS X 10.8 Mountain Lion.
Before embarking on a major OS upgrade, it would be wise, advisable and very prudent if you backup your current system to an external connected and Mac formatted Flash drive OR externally connected USB, Thunderbolt or FireWire 800, Mac formatted hard drive. Then, use either OS X Time Machine app to backup your entire system to the external drive OR purchase, install and use a data cloning app, like CarbonCopyCloner or SuperDuper, to make an exact and bootable copy (clone) of your entire Mac's internal hard drive. This step is really needed in case something goes wrong with the install of the new OS or you simply do not like the new OS, you have a very easy way/procedure to return your Mac to its former working state.
Then, determine if your Mac meets ALL minimum system install requirements.

How can I upgrade from 0S 10.6.6 to 10.7

I need to upgrade to at least OS 10.7.5. I am using a MacBook Pro (2010) 15 in. Currently I'm using 10.6.6.
What steps do I need to take, and do I have to pay for each upgrade? For example the system require. for 10.7.5 or 10.8 requires me to have at least 10.68. Do I have to pay for each upgrade step? I am running 10.6.6 currently.
Please help.
Thanks.
MJ
