Why can't I upgrade my Mac Performa to OS X?

Performa?!!\n\nYou need a new computer.  A Performa is going to be far too slow to run OSX and probably couldn't handle the upgrades that you would need to run it.  \n\nYou'd need a new processor and new more ram.  Probably a new motherboard completely because you probably don't even have enough slots for your ram to upgrade it to where it would need to be to just run bare bones X.\n\nI have a performa 33Mhz and a G3 266.  Both are OLD and outdated...\n\nIt is time for you to buy a new computer. (If you want to run X)

Reinstall the OS from scratch. Delete the partition that is there, make a new partition and install the OS.\n\nI can't remeber is the Mac has a defrag function, but do that after you install the OS, just as a paranoid step.

You can only install MacOS X if you happen to buy one of Apple's new Single or Dual core Intel processor based machines.  Otherwise, no.  It won't work on non-Apple built PCs as yet (if ever).\n\nTravis' answer is incomplete.  Yes, there may be P4 based MacOS X available for developers (when there weren't any Intel  processor Mac's available) for conversion purposes only.  There is not a general purpose OS you can run to the store or buy from Apple unless you enroll in Apple's developer program (i.e., you have applications that require conversion to the Intel platform).  Even then, that was only because Apple had no dedicated Intel hardware.  Now, Apple does and they're going to expect you to buy their hardware rather than installing it on non-Apple hardware.\n\nOtherwise, if you're looking for general purpose MacOS X to install on a standard non-Apple built PC with a P4 processor, it isn't available to the general public.  You can contact Apple like Travis suggests, but they're going to tell you the same thing I just did.

There are directions in the comments.  On top of that it only runs on specific hardware with a certain amount of RAM, and you need to have the retail version of OS X 10.4 (Tiger), plus the software to allow OS X to run on the laptop.

Its not the machine, it's the software.\n\nGet an Apple.

You can run Mac OS X on prentium Pcs. Just do a google or yahoo search for Mac OS X86 or on intel and you should be able to find a patch that makes the os run on non Apple Hardware.

You will need to do one or two things,but not at the same time.One you may have to reload or use the cd that came with the program that you are using.ANd see if it works that way.Or you may need to update you OS to newer upgrade.And if that does not work you need to check the name to see if it is spelled right they are often very UPPERCASE sentive about that.

wow, you are a little behind my friend. I am sorry to say that OS9 does not support .dmg files. you will have to upgrade. which isn't a bad thing, though it'll cost you some money

Hi there...try starting up the Macbook with the DVD disc that came with the computer.  Hold down the "C" key at startup.  Open Disk Utilities and run a verify and repair disk permissions and see if this corrects your problem and then restart the machine.  If all else fails just reinstall OS X from the disc and then do the updates.

You could install mac OSX in a virtual machine - then run your programs there.\n\nIt would be a lot of work, and the performance would really suck, but you could do it.\n\nI've included a link to a website with instructions, if you're interested.

If you don't want to install XP, then unfortunately there's now way you can run MS Flight Simulator on your Mac.  I would suggest you switch to X-Plane; it's a popular cross-platform flight simulator.\nhttp://www.x-plane.com/default.html\nhttp://www.apple.com/downloads/macosx/games/demos_updates/xplane.html

I think the bundled install discs started becoming model dependent with 10.3, eg. ibook installer only works on that model of ibook etc. If you've got a retail copy of 10.3 it should be fine.
