I can't update my iMac to 10.7.2

I just got my iMac 21" a few weeks ago and I am trying to do the software update from 10.7 to 10.7.2. However, it won't install the updates.
It is saying "The update Mac OS X Update Combined can't be saved. The update could not be verified. It may have been corrupted or tampered with during downloading. The update will be dowloaded and checked again the next time that Software Update runs."

Try downloading and running the OS X Lion Update 10.7.2 Client Combo. You may also need to download and install the Lion Recovery Update afterwards.

Several users have reported using an app called AirParrot for this purpose.

How can I update my imac g5 and I want to know how I can update it in 2014

I need to update my imac g5 but it's old so I need to know how to update it this year of 2014

The general assumption is that Apple no longer has OS 10.5 install disks. However, some people in the US have been able to get a copy by phoning the US Store at 1-800-MY-APPLE and asking for an operating system specialist, than asking for OS 10.5 install disks. Not a "sure thing" and the last ASC report of someone doing this that I've see was about 16 month ago. Still, it costs nothing to hear the word, "no," but you might get lucky.
Otherwise you are thrown into a miasma of confusing third-party offerings. Legitimate copies of old Mac OS software, especially 10.4 and 10.5 are in high demand and, as such, attract the scammers and the scalpers. I have seen legit copies of 10.5 offered for more than the market value of a used G5 iMac. Not worth it.
Try auction sites or Amazom but remember there are NO SAFE, LEGAL downloads of any Mac OS software. Some people will sell you a download license that doesn't exist. Another resource is a Mac Users group. Find one in your ara with this link:

Gray disks from another Mac model will likely not work, and a gray disk that shipped with an intel Mac definitely won't. A full retail install Leopard 10.5 disk looks like this:

Can I update an iMac from another iMac using Carbon Copy Cloner?

I change office locations every 6 months and move to a similar iMac setup. At each move, using external hard drives, I update the "older" iMac HD with the current Mail, Addressbook, work files, etc. Currently, I am using Snow Leopard; the machine I am transitioning to is behind, using Leopard.
This time something new is before me, I purchased (honestly) the Snow Leopard upgrade for the iMac that I am transitioning to. So I have an OS upgrade plus a file plus a lot of application additions/upgrades.
The question is, can I use *Carbon Copy Cloner* to make an image of my current iMac and upgrade the 2nd iMac with all my recent applications in one fell swoop? I would

Yes. Noondaywitch is correct. As long as the version of OSX is no older than the one the newest Mac came with, and the older Mac is compatible (enough RAM, etc), and the drives are formatted properly, you should be able to clone from one Mac to an external HD, then clone that back to the other one.
When you make the clone, boot up from it and run several apps, make sure your internet connection and browser work, etc.
Before cloning back to the other Mac, boot it up from the clone and do the same.
You may have to change a few settings for your internet connection, of course.

Can't update my iMac to 10.7.4, every method says file is corrupt.

I am somewhat new to Mac but I haven't had to post on this forum yet so I will try to be as clear about the issue as I can be.
I have an iMac (21.5 inch Mid 2011) and I am running 10.7.3 right now.
Software update informed there was an update available to Lion (10.7.4) so I tried to let it do it's thing and update it for me. The update downloads, then informs me that it has to restart to complete the installation. The progress bar after the restart shows it is working, and at the "Cleaning Up" stage, I am prompted with this message and only have the option to "Restart": The update "Mac OS X Update" can't be installed. The update could not be expanded, and may have been corrupted during downloading. The update will be downloaded and checked again the next time that Software Update runs.
I tried that method about 5 times, and kept getting the same thing. I read that I should try to download the .dmg files directly from Apple's site which I did. I downloaded the Combo client version and just the regular client version but when I try to open both .dmg files, I get "invalid checksum".
I did a disk utlity scan which came back to say that things were OK.
What can I do?

jdotmattinson is correct! I have the same issue.
It is a router/ISP issue. Tried the software update drop down for 10.7.4, failed. Tried to download 10.7.4 Combo Client update, invalid checksum. Tried to download 10.7.3 Combo client update, invalid checksum.
Went over to Win7 Dell laptop, downloaded 10.7.4 Combo update, transferred to MacMini via USB drive. Invalid checksum. WHICH led me to diagnose it wasn't my Mac, but Apple's servers or my ISP/Router.
Went to work, downloaded on XP, put on USB drive, brought it home, copied, installed just fine!
Did a hard factory reset on Motorola Surfboard SBG5560, invalid checksum again.
Going to buy a new router tonight and test it again with dowloading 10.7.4 Combo update. Will keep you posted to see if that fixes it.
Btw, if a new one doesn't fix it then it's my Comcast ISP service that is messing it up. Which is going to make me cry....check out this link... be afraid, be VERY afraid if this is the problem/solution.

How can I update my iMac 10.5.8 up to mavericks?

Okay so, I have an iMac OS X, bought it in 2006, and I wish to update it to Mavericks.
The problem I have, my Mac doesn't have the App Store, and the only way to get the App Store is to update the computer to Snow leopard. Do I really have to purchace Snow Leopardin order to get to Mavericks?
Please and Thanks

A 2006 model cannot run Mavericks. It can run Snow Leopard and Lion.
Upgrading to Snow Leopard
You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mavericks if your computer meets the requirements.
     Snow Leopard General Requirements
       1. Mac computer with an Intel processor
       2. 1GB of memory
       3. 5GB of available disk space
       4. DVD drive for installation
       5. Some features require a compatible Internet service provider;
           fees may apply.
       6. Some features require Apple’s iCloud services; fees and
           terms apply.
Upgrading to Lion
If your computer does not meet the requirements to install Mavericks, it may still meet the requirements to install Lion.
You can purchase Lion at the Online Apple Store. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
     Lion System Requirements
       1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
           or Xeon processor
       2. 2GB of memory
       3. OS X v10.6.6 or later (v10.6.8 recommended)
       4. 7GB of available space
       5. Some features require an Apple ID; terms apply.

What can I update my imac Tiger 10.4.11 to?

I've been reading and it sounds like the best I can do is update the software to Lion and order additional 3 GB of memory - but is that enough to run Lion? Or am I better off just upgrading to snow leopard?   Also, if upgrading how do I do a backup or could I take imac to the local Apple Store and they could help? I inherited this imac and I love it but I know technical support, etc. has expired so not sure what help I can get?

In order to get to Lion, you will have to upgrade to Snow Leopard first.
Your iMac 6,1 can only be upgraded to Lion.

Can i update my 10.5.8 to 10.7

Can i update my imac which is 10.5.8 to 10.7 for itunes.
I hve tried and said it has to be 10.6 or above?

Start by checking if you can run Snow Leopard:
Requirements for OS X 10.6 'Snow Leopard'
http://support.apple.com/kb/SP575
Whilst Apple withdrew Snow Leopard from their stores, you can still get it from Apple by calling 1-800-MY-APPLE (if you are in the USA) and they will supply the SL DVD for $20 for a single user, or $30 for a family pack that covers up to 5 Macs. You can also purchase the code to use to download Lion from the same number (Lion requires an Intel-based Mac with a Core 2 Duo, i3, i5, i7 or Xeon processor and 2GB of RAM, running the latest version of Snow Leopard), or you can purchase Mountain Lion from the App Store - if you can run that:
http://www.apple.com/osx/specs/
If you are outside the US call your national Apple Helpline:
http://support.apple.com/kb/HE57
If you're in the UK, use this number: 0871 508 4400
When you have installed it, run Software Update to download and install the latest updates for Snow Leopard.
UPDATE:
OS 10.6 Snow Leopard is once again available from the Apple Store:
http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard
and in the UK:
http://store.apple.com/uk/product/MC573/mac-os-x-106-snow-leopard
but nobody knows for how long it will be available.
To use iCloud you have to upgrade all the way to Mountain Lion:

IPod 4,1 will not update to iOS 7. I updated my iMac to 10.9.1 (maverick). Latest Numbers version on iMac is not compatible with Numbers on iPod. Ideas? Can I go back a version with Numbers?

iPod 4,1 will not update to iOS 7. I updated my iMac to 10.9.1 (maverick). Latest Numbers version on iMac is not compatible with Numbers on iPod. Ideas? Can I go back a version with Numbers? I downloaded old version of Numbers 2.0.1 from DVD but with both versions the 2.0.1 will not open. So both versions are present but only the new version functions. I tried to drag the new version to the trash but the old version still runs error message and will not open. I did not try to restart with the new version in the trash.

Maybe. See:

I bought my iMac from someone. Everything was changed over to my name however when I try to update programs it only shows the old users apple ID and I can't update. How do I change this so I can update the applications and have everything fully under me?

The first thing to do with a second-hand computer is to erase the internal drive and install a clean copy of OS X. You — not the previous owner — must do that. How you do it depends on the model, and on whether you already own another Mac. If you're not sure of the model, enter the serial number on this page. Then find the model on this page to see what OS version was originally installed.
1. You don't own another Mac.
If the machine shipped with OS X 10.4 or 10.5, you need a boxed and shrink-wrapped retail Snow Leopard (OS X 10.6) installation disc from the Apple Store or a reputable reseller — not from eBay or anything of the kind. If the machine has less than 1 GB of memory, you'll need to add more in order to install 10.6. Preferably, install as much memory as it can take, according to the technical specifications.
If the machine shipped with OS X 10.6, you need the installation media that came with it: gray installation discs, or a USB flash drive for some MacBook Air models. For early MBA models, you may need a USB optical drive or Remote Disc. You should have received the media from the previous owner, but if you didn't, order replacements from Apple. A retail disc, or the gray discs from another model, will not work.
To boot from an optical disc or a flash drive, insert it, then reboot and hold down the C key at the startup chime. Release the key when you see the gray Apple logo on the screen.
If the machine shipped with OS X 10.7 or later, you don't need media. It should boot into Internet Recovery mode when you hold down the key combination option-command-R at the startup chime. Release the keys when you see a spinning globe.
2. You do own another Mac.
If you already own another Mac that was upgraded in the App Store to the version of OS X that you want to install, and if the new Mac is compatible with it, then you can install it. Use Recovery Disk Assistant to create a bootable USB device and boot the new Mac from it by holding down the C key at the startup chime. Alternatively, if you have a Time Machine backup of OS X 10.7.3 or later on an external hard drive (not a Time Capsule or other network device), you can boot from that by holding down the option key and selecting it from the row of icons that appears. Note that if your other Mac was never upgraded in the App Store, you can't use this method.
Once booted in Recovery, launch Disk Utility and select the icon of the internal drive — not any of the volume icons nested beneath it. In the Partition tab, select the default options: a GUID partition table with one data volume in Mac OS Extended (Journaled) format. This operation will permanently remove all existing data on the drive.
After partitioning, quit Disk Utility and run the OS X Installer. You will need the Apple ID and password that you used to upgrade. When the installation is done, the system will automatically reboot into the Setup Assistant, which will prompt you to transfer the data from another Mac, its backups, or from a Windows computer. If you have any data to transfer, this is usually the best time to do it.
Then run Software Update and install all available system updates from Apple. To upgrade to a major version of OS X newer than 10.6, get it from the Mac App Store. Note that you can't keep an upgraded version that was installed by the previous owner. He or she can't legally transfer it to you, and without the Apple ID you won't be able to update it in Software Update or reinstall, if that becomes necessary. The same goes for any App Store products that the previous owner installed — you have to repurchase them.
3. Other issues
If you see a lock screen when trying to boot from installation media or in Recovery mode, then a firmware password was set by the previous owner, or the machine was remotely locked via iCloud. You'll either have to contact the owner or take the machine to an Apple Store or another authorized service provider to be unlocked. You may be asked for proof of ownership.
If the previous owner "accepted" the bundled iLife applications (iPhoto, iMovie, and Garage Band) in the App Store so that he or she could update them, then they're linked to that Apple ID and you won't be able to download them without buying them. Reportedly, Mac App Store Customer Service has sometimes issued redemption codes for these apps to second owners who asked.
If the previous owner didn't deauthorize the computer in the iTunes Store under his Apple ID, you wont be able to authorize it immediately under your ID. In that case, you'll either have to wait up to 90 days or contact iTunes Support.
When trying to create a new iCloud account, you might get a failure message: "Account limit reached." Apple imposes a limit of three iCloud account setups per device. Erasing the device does not reset the limit. You can still use an account that was created on another device, but you won't be able to create a new one. Contact iCloud Support for more information.

How can I update my iPod classic that will not mount on iMac computer?

I can't update my iPod classic from my iTunes on my iMac computer with OSX 10.9. It will not mount or be recognized by iTunes version 12.1.
I plug it into the USB port and it charges, gives the "Do not disconnect" symbol but the computer does not recognize or mount the iPod at all. I haven't been able to update the music for years. I have four other devices associated with my Apple ID for automatic downloads. Is it too antiquated to upload any of my music from my computer to it anymore?

Ahh! The plot thickens!
I went thru the console and read the error logs. It appears that the .ipsw file does load.....I think. It's been years since I spoke computer....
Here is what I got after double clicking the .ipsw file and iTunes opened:
