Why can't I upgrade to Firefox 4.0, I have Mac OS 10.5.8, with Processor PowerPC G5 (3.1); Speed 2.1 GHz

For older Macs that aren't supported in Firefox 4.0, try TenFourFox for PowerPC's running Mac 10.4.11 & 10.5.8 .

HT201364 Why can't I upgrade to Lion or Mt. Lion (from Snow Leopard) - older MacBook but adequate processor, HD space and 4GB of RAM?

Many applications appear to require newer OS, which I get, but what is the technical reason (other than performance) that the newer OS won't run on the older albeit capable machines? I don't want to upgrade hardware, but...
So is there a work around or not (advisable?)???

Thanks, but at the risk of sounding like one of my kids... WHY?
I read your link provided - thankyou! But still a bit perplexed because of my configuration seems to match the minimum requirements indicated:
Hardware Overview:
Model Name: MacBook
Model Identifier: MacBook3,1
Processor Name: Intel Core 2 Duo
Processor Speed: 2.2 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 4 MB
Memory: 4 GB
Bus Speed: 800 MHz
Boot ROM Version: MB31.008E.B02
SMC Version (system): 1.24f3
Serial Number (system): W8******0HC
Hardware UUID:
Sudden Motion Sensor:
State: Enabled
But the upgrade scan tool must be picking up some other limitation. I guess I'll need to ask one of the "Genius Bar" at the local Apple store.
Thanks again!

Why can't I upgraded to lion from snow leopard

You will need to provide more information. Your question is too vague to answer.

Why can't I upgrade from 10.5.8 to 10.6? My MPB spits out the disc before it ever appears on the desktop.

Why can't I upgrade from 10.5.8 to 10.6.3? My MPB spits out the disk before it ever appears on the desktop. The Snow Leopard disk is brand new, was still in shrink wrap until I opened it. I do have the hard drive partitioned, running Win XP with Boot Camp, if that might be the issue.

Hey vlntrg,
I have a 2002 model Powerbook that will sometimes (most of the time) refuse to mount a CD or DVD. It just grunts for a while and then spits it back out. When this happens, I will slap the bottom of the machine several times with an open hand, not too hard and not too soft. I read this somewhere online (I forget where), and I was hesitant to try it, but it was cheaper than replacing the SuperDrive.
This will often allow me to insert and use the CD or DVD. I have also noticed that I have less trouble when the machine is cold than when it's warm.
I've not had this trouble with my MacBook Pro.
Another thought. Would it be possible to boot your machine in target disk mode and update your software using a friend's Mac? I'm sure there are others here who can better answer that question.
Hope this helps.
Andy

Why can't I upgrade to yosemite? I'm currently running snow leopard on my white macbook.

Why can't I upgrade to yosemite? I'm currently running snow leopard on my white macbook.

White MacBooks are NOT eligible to upgrade to either 10.8 Mounain Lion, 10.9 Mavericks or 10.10 Yosemite.
You maybe able to upgrade your white MacBook to OS X 10.7 Lion
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)
7 GB of available disk space
2 GB of RAM
You can purchase a OS X 10.7 Download code here.
http://store.apple.com/us/product/D6106Z/A/os-x-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.
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.
http://roaringapps.com/
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 download OS X 10.7 Luon from 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 by using the paid download code to Download and install OS X 10.7 Lion rom the Mac App Store.
Good Luck!

Why can I not upgrade my iCloud storage on iOS

Why can I not upgrade my iCloud storage on iOS

Hard to say why that would be. Suggest you contact iTunes store support for help with this: http://www.apple.com/emea/support/itunes/contact.html. They normally deal with iTunes and app store issues, but they should be able to tell you if there's an issue with your iTunes account that is preventing the purchase and how to correct it.

IWork purchased on disc in 2011. Why can't I upgrade free?

I bought iWork on disc at BestBuy with my MBP in 2011. But when I click on Pages, Numbers or Keynote in the App store I get the message, "Pages 4.3 is already installed but was not purchased on the App store. Would you like to purchase? $19.99"
Why can't I upgrade? I did buy it, but at the time it was not even AVAILABLE in the app store.

Then why do we read this ....
Pricing & Availability

Existing users running Mavericks can update their apps for free from the Mac App Store℠. iWork and iLife for iOS are available for free from the App Store℠ for any new device running iOS 7, and are also available as free updates for existing users.

HT4972 why can't I upgrade my Iphone 4 to IOS 5 or 6?

why can't I upgrade my iphone 4 to IOS5 or later

What happens when you connect the iPhone to your syncing computer and start iTunes? Are you prompted that there is an upgrade available? What version of iTunes is on the computer? What Operating System is on the computer? What version of iOS is on the iPhone?

Why can I not upgrade my iTouch 3rd Generation to iOS 5? I can upgrade my other one...

Why can I not upgrade my iTouch 3rd Generation to iOS 5? I can upgrade my other one...

Are you sure it's a 3rd Gen? If it's an 8GB or 16GB model then it's a 2nd Gen and 4.2.1 is the latest
What happens when you try?

My credit card expired and now I can't update paid for apps. Why can't I upgrade without a credit card?

The "None" option is not available. Presumably because I have already purchased on that Apple ID with a credit card.
That is not likely the case. As you can see in my account in the US store I have a bank card in place and I have the None option.

Why can't I get the Flash Player 11 for my Mac?

Why can't I upgrade to Flash player 11 on my iMac desktop? It is an OS X Version 10. 5. 8.

There is no flash player for the iphone and Adobe would be the one to develop one, not Apple. And there are no plugins to install instead, as far as I know.

Hello royalaqua,
I do think you should ask yourself if upgrading to Lion is the right course to take.
Snow Leopard is an excellent OS and Lion has literally been frozen out after barely a year. Remember too that some of your apps may not work with Lion (those that have Rosetta, for example) so that could mean more new purchases. Plus you may need to uprate your RAM too.

Why can't I download trial for Acrobat Pro on my Mac?

Why can't I download trial for Acrobat Pro on my Mac? I get an error message. I click the download: "Install Adobe Download Assistant", then click on it, see Adobe AIR application instaler, then get "Sorry, and error has occurred. This application cannot be installed because this installer has been mis-configured. Please contact the application author for assistance." If I knew who the application author was, I'd contact him! Thanks, Pete

Hey PetaPete,
There are some known issues when downloading Adobe Download Assistant which you can find at:
Troubleshoot Adobe Download Assistant
So, you might alternatively need to try downloading Acrobat from the link given below:
http://prodesigntools.com/adobe-acrobat-xi-pro-standard-reader-direct-download-links.html
Note:
1) You need to stay on the Adobe trial page for the respective product that you're downloading. You should be signed in.
2) Copy/ Paste trial link for the files that you're downloading from Prodesigntools on to the address bar of Adobe trial page and hit enter.
Regards,
Anubha
