HT201364 Cannot upgrade OS to Yosemite

I cannot upgrade OS to Yosemite despite meeting all the technical requirements (10.6.8 and iMac).
I click on the Yosemite link at the App Store but it looks like it's trying to bring up a Mavericks page.

An iMac5,1 can't be upgraded past Lion 10.7.5.

HT201364 Cannot upgrade to Maverick

I have a MacAir purchased in Nov 2008. It has 2 GB RAM and OS X 10.6.8. However, when I click on OS X Maverick upgrade, it says cannot upgrade. Any idea why? Thanks.

After you find the Model Identifier, go to this page:
http://support.apple.com/specs/
Copy the Serial number in the "Search Tech Specs" search box. This will take you to the info on your computer. You can also check to see how much RAM you can install.
While 2GB RAM is the minimum recommended, I suggest you upgrade your RAM to 4GB or higher. Otherwise you might be better off in Snow Leopard.

I cannot upgrade Flash with yosemite

I have a macbook pro with yosemite. It is impossible for me to upgrade or uninstall Flash. I have tried everything. What can I do....I see much advice about uninstalling yosemite.

Uninstall Flash Player | Mac OS
This is the current version of Flash: Adobe Flash Player 16.0.0.305. If you are really running Snow Leopard, then look for a compatible version here: Adobe Flash Player - Downloads.

HT201364 Cannot upgrade my mid 2011 iMac 21.5 inch from Lion OS X 10.7.5 to Mavericks.

After accessing Mavericks upgrade page in the App store, signing in using my Apple ID and clicking "install," nothing happens.

solocyclist,
Mavericks is a download of over 5 GB — have you given it enough time to download?

I upgraded to OS Yosemite on my MacBook Air...and I cannot upgrade the Adobe Flash download that Adobe keeps asking me to download. I get the screen and when I click on the icon it just creates a new window but not download. Thoughts?

I just tried the link and it is just fine. If the GateKeeper pops up then open Security & Privacy preferences, click on the General tab, set the last radio button to Anywhere.

Since my macbook pro is an intel core duo but not a core 2 duo, I cannot upgrade to Yosemite. So... what OS X can I upgrade to with this computer?

Since my macbook pro is an intel core duo but not a core 2 duo, I cannot upgrade to Yosemite. So... what OS X can I upgrade to with this computer? Thanks for the input.

Intel Core Duo is a 32-bit processor, so the latest Mac OS X version you can install is Mac OS X Snow Leopard -> http://store.apple.com/us/product/MC573Z/A/mac-os-x-106-snow-leopard
You are running Mac OS X 10.6.8, so you are already running the most recent Mac OS X version for your computer.

Cannot run FCPX on Yosemite

NEED HELP! I cannot run my Final Cut Pro 10.1 on my Macbook air after upgrading OS to Yosemite.
I tried many ways such as putting app into trash and reinstall ... didn't work.

TYou need to upgrade to version 10.1.3.

How do I upgrade iPhoto for Yosemite?

How do I upgrade iPhoto for Yosemite 10.10.3?

You ned to upgrade or update iPhoto 9.6.1 with Yosemite 10.10.3, and that update version is only available from the App Store.
It will depend on the iPhoto version you own, if you still can update to a Yosemite compatible version. If you have any version of iPhoto '11, and it is listed at the Appstore among your purchases, you can move the incompatible version to the Trash and reload the appStore Purchases page with ⌘R. Then try, to reinstall from that page.
If you own an older iPhoto version, you cannot update it, you need to buy iPhoto '11, bu apple is no longer selling it. And the retail versions on iLife installer CDs are not compatible with Yosemite.

Cannot printer share in Yosemite

This follows my question here: Cannot printer share in Mavericks.
Unfortunately, I haven't been able to printer share since upgrading both the iMac and MacBook Air to Mavericks. Upgrading both to Yosemite has not, unfortunately, fixed the problem. As before:
The iMac can print to my HP OfficeJet Pro 8000 A809 as always. It still has "Share this printer on the network" ticked. But now I cannot print from the Air.
I removed the printer on the Air and added it back, but get "Unable to download the software from the server at this time."
I therefore downloaded all HP printer drivers and rather than selecting the printer from the "Nearby Printers" list, clicked "Add Printer or Scanner ...", selected the printer there, waited for "Gathering printer information", clicked Use _ Select Software, and picked the selected the printer in question. Clicked Add.
I go to print something, and I get "Printing - Printing page 1, 34% complete...". And that's where it sits.
Help. Any ideas most welcome. Thanks in advance.

Thanks for that good troubleshooting.
Well, it does sound like a network problem (583 ms is a very long response time).
(but I can't rule out the need to reinstall Mavericks - yet)
Tell me a little about your local network. Model router, location/distance between iMac & MacBook & router, are you in an apartment with many other routers around you, etc? Both computers using wifi?
Things to try:
I would scan for signal strength and to see other competing routers on same channel. Use the scan tool in Mavericks - read here:
http://ambroselittle.wordpress.com/2013/11/09/mac-wi-fi-scanner-in-os-x-maverick s/
(you can reduce interference by setting your router's channel to a different one than everybody else is using.)
I would also set up the router to have "reserved IP addresses" for each computer in the router's online admin web page. This reduces the searching that gets done by computers and router. You can usually use the same IP address each computer currently has, just make it reserved. On my netgear router, setting up the reserved IPs is on a different menu/page than "connected devices."
Please report back with your results.

Using Yosemite 10.1.1 with Safari browser

this is the answer I found on Mac support forums that worked right away. The old flash player plug in was not removed by the new installer. copied to give post person credit.

Re: safari 6.0 flash problem (blocked plug in)
Jul 26, 2012 7:39 AM (in response to defconnect5)
I have a new MacBook Pro and I followed these instructions, downlonading and installing the new Flash plugin. But when I looked in "/Library/Internet Plugins" there was no folder called "Disabled Plugins".
However, I did see two versions of Flash:
_Flash Player.plugin with old date
Flash Player.plugin with todays date
I deleted _Flash Player.plugin and this fixed the problem.

TIP: DO NOT UPGRADE TO OSX YOSEMITE!!!

If you are on a Mac (unfortunately I'm forced to use one at the office), do not, I repeat, do NOT "upgrade" to OSX Yosemite. Adobe still hasn't figured out the conflicts between EA and Yosemite. I've been fighting issues all day with lock ups, etc. If you want to keep your sanity, wait to upgrade the OS until Adobe issues a patch.
On a side note, I can't wait to get back to my PC at home. No issues there...

My user experience with Yosemite:
Both versions can be installed "side by side". I mean: Edge 4.0 and 5.0.1
The download page:

I cannot upgrade from iOS 5.-01 to 5.1 on original iPad

My wife and I both have iPads running 5.0.1. Mine is v2 and hers is v1. We both have Macs with 10.7.3 and iTunes 10.6.
When I tried upgraded to 5.1 throguh iTunes I got messages saying I could not connect to the server. A friend suggested I reboot the iPad and my Mac. I did and the upgrade went fine.
I cannot upgrade my wife's iPad, however. Even after rebooting I get an error saying iTunes cannot download the upgrade because her computer is not hooked up to the internet. It is, however. I can access the iTunes store, use Safari, and get e-mail. I then tried to download the upgrade directly through the iPad but after a few minutes I get a message saying the updte failed.
Any suggestions?

Problem solved. I upgraded after switching a cable. Not sure why that mattered but all is fine now.
