CONNECTED MY MONITOR TO MY NEW MAC INTEL OS X 10.6 SNOW LEOPARD, AND THE MONITOR JUST SITS THERE, YELLOW LIGHT IS ON, SAYS IT IS IN POWER SAVE MODE, MONITOR PROGRAM IN COMPUTER CANNOT DETECT DISPLAY, DIS CONNECTED IT FROM MAC OSX 10.5, WHERE IT WORKED JUST FINE. SONY CPD-E400, IN POWER SAVE MODE, TRIED TO TAP ANY KEY ON KEY BOARD

You can buy in an Apple store (physical or online)
Mac OS 10 6 Snow Leopard

The problem appears to be that your ibook is only a G4 processor snow leopard needs an intel processor. The highest system you can instal on it is 10.5 i.e. leopard.

Firstly you will need to buy a copy of 10.6. This is available from Apple (see link below) or you could get a copy from eBay.
Mac OS 10 6 Snow Leopard

The following article will tell you what to do next:
An Easy Guide to Installing Basic Upgrades in OS Snow Leopard 10 6

Unfortunately Snow Leopard requires a intel processor to work so the G5 imac will not be able to run the system.

Unfortunately Snow Leopard is only compatible with intel macs which the emac is not.

This is the best solution for that problem and works perfectly...

If it is a G4 PowerPC processor No
If it is an Intel Processor Yes

If you updated from Leopard to Snow Leopard you should note that safari for Snow Leopard is different from that for Leopard. Do a clean instal of Snow Leopard and that should sort the problem out. Hope this helps

Apple's next major Mac OS X released, will focus solely on under-the-bonnet changes, the Mac maker has revealed. PowerPC-based machines might be left in the cold?

Apple is promising a version of Mac OS X that "dramatically" reduces the amount of storage space the operating system requires. Undoubtedly, some of that will come from the re-engineered core technologies, but it's hard to conclude that Snow Leopard's release will come not as a "universal" binary capable of running on both Intel and PowerPC processors, but as a single-platform product.

Universality has been handy in ensuring users can run the same installed code on both Intel- and PowerPC-based Macs without resorting to emulation. But just as Leopard lacks the ability to run Mac OS 9 apps - a feature present in previous Mac OS X releases - there will come a time when Apple drops Rosetta, its PowerPC emulation mechanism.

Early rumours concerning Snow Leopard suggested PowerPC support was to be dropped, though that was subsequently denied by Apple.

How can these two claims be reconciled? Only by Apple shipping native-only versions of Snow Leopard. Owners of Intel-based Macs will finally be free of all that redundant PowerPC code in the system software, freeing up space for, as Apple puts it, "their music and photos".

With any luck, Apple will finally allow users to readily remove unwanted languages from their system software, a process that can free up a fair bit of hard drive space too.

Apple won't be ditching support for universal binaries, or PowerPC Macs, because there, for now, too many of them out there. But if Snow Leopard's Grand Central technology does as promised and improves the OS' ability to work with multi-core CPUs, Intel-based Macs are going to shoot even further ahead of old G5 and G4 models.

Apple is also promising that Snow Leopard will offer more pervasive support for 64-bit computing, leading to the ability to support up to 16TB of memory, though the motherboard hardware to do this isn't there yet. In any case, limits to CPU memory controllers mean they don't physically support the full range of 64-bit memory addresses, only a subset.

Snow Leopard will also feature QuickTime X, a "streamlined" revamp of Apple's multimedia foundation, and OpenCL (Open Compute Library), a non-proprietary programming system for running complex code on a machine's graphic chip(s).

Oh, and it'll get Microsoft Exchange support too, in a bid to make Macs more business-friendly.
