I've informed the author of the page, but they may not correct it for awhile.
if you want to skip installing update one by one from OS 10.5 or older you must buy lion usb storage,
Note : you must erase you hard drive
- you boot fron this usb ( hold down option key ( ATL on some keyboard ) , chose USB and folow steps, first chose disk utility to erase you hard drive, and after you can start clean install of lion,
here is the link to buy :
Look under your Apple Menu > About this Mac > More Information
Your looking for a model like "iMac 7,1" for instance.
Many iMac's came with 10.4, as late as 2007, some can run OS X 10.7
I advise any Mac older than 3 years to stick with 10.6 as it's faster and the investement in new software, sometimes even new third party hardware (need new drivers software), problems with hardware, slowness etc., almost doesn't make it worth the effort to go to 10.7 Lion, especially if your not a computer geek.
Another thing, 10.8 Mountain Lion is just about to be released, won't run on older hardware, so your "behind" once again.
Model Year Can run Lion? Performance?
iMac 7,1 2007-2008 Yes - your best bet - with a "fresh install" via the $69 Lion USB thumb drive.
iMac 6,1 2006-2007 Yes - eh? likely slow
iMac 5,1 2006-2007 Yes - eh? - "
iMac 5,2 2006-2007 Yes - eh? - "
iMac 4,1 Early 2006 No 10.6.8 max
Anything "PowerMac" in the model name can't run 10.6 or anything further like 10.7+ 10.5.8 is the max.
There is one important thing, Apple is providing security updates for 10.5 Intel and 10.6+, but not 10.4.
My advice for you, since you haven't upgraded OS X at all in all these years, is to have a local Mac/PC specialist backup your files, then upgrade the machine to 10.6.8 max and leave it at that, return your files.
This way your performance will be somewhat decent, you can install software and get security updates.
The 10.6 install disk can be gotten here, it's required if your going to upgrade to 10.7 via the AppStore for $29 (fast & reliable Internet needed)
10.6 will be supported (and likely be 40% OS X market share) by this time NEXT year, so no need to worry about 10.7 on your older Intel processor based hardware.
Save your money for the new iMac's coming out next year sometime with 10.8 on it.
Hi noondaywitch it was Magovil not magoliv , yes i am up since now for more technical help just put question !
there is no slow performance when all minimum requirement to install loin are present regardless of what is and when your mac had been purshassed, go to support and do search for the article HT4949 for requirement , a copy willl folow :
OS X Lion system requirements
To use Lion, make sure your computer has the following:
- An Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor
- Mac OS X v10.6.6 or later to install via the Mac App Store (v10.6.8 recommended); you can install without Mac OS X v10.6 by using an OS X Lion USB Thumb Drive, available on the Apple Online Store
- 7 GB of available disk space
- 2 GB of RAM
If your Mac does not meet these requirements, you will need to upgrade your Mac before installing Lion.
i add for mountain Lion 8 GB of free disk space are required
