OS 10.5 = Windows Vista?

*"Pro Tools doesn't support OS 10.5."*

Yes it does...ProTools 7.4 is supported on 10.5.1. Your mileage may vary running it on 10.5.2.

*"The iMac won't recognize the CD as a bootable disc"*

That's because OS 10.4 does not have the necessary hardware support to run your iMac. This has been covered many times on these forums.

Pro Tools HD works with Leopard. Pro Tools LE is pending an update. It isn't Apple's fault that it doesn't work on Leopard; it's Digidesign's fault.

You won't be able to run Tiger on your new iMac. Operating systems older than the one that shipped with a computer normally can't be installed on that computer. This has been the case with Apple for a long, long time; since the beginning if I am not mistaken. It is not exclusive to Apple either; it's quite normal in the PC world too.

What sort of problem are you having with Mail? Try posting a more detailed question the Mail forum.

OS 10.5 reminds me of Vista, only not as bad. Mail won't operate properly. I was running Pro Tools and a Digidesign 003 on Windows, and since PT has always been built for the Mac, I thought it'd be a seamless switch.

If you have specific problems with Mail, that a thread and describe your problems. It works fine for most of us.

Those Pro tools were not originally written by Apple. It is very likely they were full of old code that had been deprecated for years and they never updated it because it kept working. Apple finally pulled the plug on that old code, after about 3 years' notice, and "all of the sudden" it doesn't work anymore.

Mail won't operate properly.

Let's start by troubleshooting why Mail won't operate properly.

1. Do you have high speed internet, or dialup?
2. Are you able to browse the web?
3. Do you have a non-Apple hub, WiFi access point, router, or just a straight ethernet modem, or is USB involved in some way, or is it just an Apple Airport Base station connected to an ethernet based modem?
4. Are you connected via DHCP or PPPoE or PPPoA or static IP?
5. Are you setting up your SMTP server to be the same as provided by the people giving you your internet juice, or someone else?
6. Are you connecting to a POP, IMAP, or Exchange server via Mail?

10.4 will not install on a Mac which shipped with 10.5. Macs have never booted from a system that is older than what they came with.
You must use the original installer disc to install 10.5 on your Mac. If yours did not ship with a disc, and you bought new, call Applecare for a replacement disc.

10.5 has distinct advantages over Vista. Less risk of viruses and spyware. Less obstructive wizards.

The problem of Protools is their plugins and software need to be updated for the latest drivers. Digidesign unfortunately has been slow bringing all those up to date. That's really their problem. They've had now 8 months to do it. Complain to Digidesign.

The Mail problem is one that seems to be very common. I'm using a cable modem with a LinkSys wireless router I'm able to receve, but not send. I'm getting a port error and timeout response.

The problem is likely an issue with the Linksys router. Try directly connecting your system into the modem. Wireless routers right now are in a limbo state because many of the specifications are in a draft mode. Unless you use a known good spec from the router, you are basically beta testing their hardware. In addition, Comcast has a history of issues with their SMTP servers timing out. They do this to prevent spamming. So if you are on Comcast, or some other provider that has some issues like that, it is no surprise. It has nothing to do with the fact you have a Mac. Sometimes also Comcast, or the Linksys may not be familiar with IPv6, which Macs have enabled by default. Your System Preferences allows you to disable this feature. This is a case of either the operating system is newer than the hardware connecting over it, or the internet service provider.

A few years ago, I used the Blue & White tower. it came with OS 9. I was able to install older OS's like 8.7. I'm not certain of this, but I think I installed OS 10.1 on my Mac Book which came with 10.2 or 10.3.

Mac OS 8.6.1 was the last 8 version. There never was an 8.7. The Blue and White's oldest operating system was 8.5.1. You can read more about it here:

http://docs.info.apple.com/article.html?artnum=25517

So your ability to install 8.6.1 on it or 8.6 is no surprise. It was still not an older operating system. The fact it came with 9 was probably because you bought it used, or it was bought during an up to date period when 9 was being offered on an up to date program. It still came with 8.5.1 minimum. So no, you weren't installing an older operating system than the Mac.

However, the problem is being addressed in the appropriate group, where MANY others are having the same problem. I never went into detail about the mail issue because it's not the correct group for it.

Hopefully this problem will be solved in the other forum. Rest assured, however, that Mail will not be at fault.

This really hasn't changed any. For all Macs, you can install the OS that it came with as well as any future OS that supports that particular machine. There will be a different set of compatible OS versions for each machine. Your old B&W could do 8, 8.5, 9, 10, 10.1, 10.2, 10.3, and 10.4. That was a particularly nice and long-lived design. I have a Macbook that can run 10.4 and 10.5. My wife has a virtually identical (but not quite) Macbook that can only run 10.5.

Your old B&W could do 8, 8.5, 9, 10, 10.1, 10.2, 10.3, and 10.4.

Actually Blue and White's minimum is 8.5.1 as I already stated and gave reference to. 8.5, and 8.0, and 8.1 for that matter can't be run on a Blue and White.

Hey! That was 8 years ago. I was going from memory and I think I was pretty close 🙂
