After installing new operating system windows 7 on imac 27, mac stopped working.

We bought new imac 27, late 2012. Installed windows 7, mac stopped working. We restarted mac os, but system cant see hard disk. Cant install mac. What to do?

How did you install Windows 7? Via Boot Camp, using a Windows 7 system builder disk, or with Parallels or VMWare's Fusion?
If you installed using Boot Camp, it sounds as if you goofed and installed Windows onto the Mac partition instead of the Windows partition. What happens when you hold down the Option key when you restart the Mac? Do you see a Mac partition and a Windows partition?
I would suggest seeing if you can use the Recovery mode on your new iMac to reinstall your iMac's operating system if you installed Windows over it by mistake. Please see this Apple Support document on how to accomplish this:
http://support.apple.com/kb/PH11273?viewlocale=en_US&locale=en_US
If you installed Windows using Parallels or Fusion, I can't help you, as I've zero experience with either.

After installing new operating system, I can't connect to internet from an e-mail. What is wrong?

After installing the new operating system, I can't access the internet from an e-mail request. What' wrong?

Finally gave in and called Apple Support.
1) They had me restart while holding down the Option-Command-P-R keys (this resets the HW apparently. Didn't fix it.
2) Next they had me move my System Preferences folder to the trash. Still didn't fix it.
3) Lastly they had me move all my cache files to the trash and then empty the trash. Restarted and it seems to be fixed now.
I was told that sometimes after an upgrade if you don't "delete all your caches" that there can be problems. I'll have to see if the connection holds up since before the problem was intermittent, but at least now I have a case number and all seems well so far.
I encourage those who are experiencing issues to please call Apple Support - it appears that there is no one fix and it depends on so many different factors. If this issue re-appears I'll be back on the phone with them - plus I'll update this thread.
Thanks!

After installing new operating system software, my user account name has been changed and i don't know the password.

i need help!
I just installed Mac OS Maverick in my laptop, but when i checked the Users&Groups There are only 2 User name 1 is "Apple(admin) and 2 is Guest, my user account name has been changed even the password. how can i retrieve my old user account name and password or how can i changed it?

Here's an updated set of instructions you can try:
Make sure you are signed into iMessage and FaceTime with your current ID. If they are signed into the old ID, go to Settings>Messages>Send & Receive and Settings>FaceTime, tap the ID, sign out, then sign back in with your current ID.
Then temporarily recreate the old ID by going to https://appleid.apple.com, click Manage my Apple ID and sign in with your current iCloud ID. Click edit next to the primary email account, change it back to your old email address and save the change. (You should not have to verify the old email account so it doesn’t matter if you no longer have access to it.) Now go to Settings>iCloud, turn off Find My iDevice and enter your current password when prompted (even though it prompts you for the password for your old ID). Then save any photo stream photos that you wish to keep to your camera roll (unless using iCloud Photo Library). When finished go to Settings>iCloud, tap Sign Out (or Delete Account if you are not running iOS 8) and choose Delete from My iDevice when prompted (your iCloud data will still be in iCloud). Next, go back to https://appleid.apple.com and change your primary email address back to the way it was. Now you can go to Settings>iCloud and sign back in with your current iCloud ID and password (your data will download back to your device).

Have you failed to maintain a backup copy?
You should never update without making sure your backup copy of your computer is up to date.
You can transfer itunes purchases from an ipod to computer: File>Devices>Transfer Purchases

Installed new operating system

I just installed a new operating system and had to re-install itunes. it counted that as one of my "uses" of my music library. how do i reset that so that I am able to use my new ipod?

Hello, Annie, and welcome to the Discussions.
Sorry, but what do you mean by "reset"? You shouldn't have to do anything special, as long as you have your content in iTunes. Just attach your iPod and it should offer to sync to the iTunes library automatically.
You may need to describe more fully what it is you're trying to accomplish.
Regards.

Installing New Operating System

Is there any way to install an operating system that was made for a different apple machine. Each time I try to do it, it tells me that it can't install the bundled apps on my computer. I would like to just install the OS, but there doesnt seem to be that option...

Ah, now I probably see my problem. The game is Law and Order: Dead on the Money. Was made for 10.2.8 However, there was some kind of problem with Java and Java 3D and, so, they made a patch for it. However, the patch only works with 10.3 (or so I thought). It probably works for 10.3 or higher, but not on Intel Macs. So, I've got my MacBook which has an appropriate operating system but an Intel chip and I've got my eMac with the right hardware, but only 10.2.8. I've got my copy of 10.4 that came with my MacBook that I can't install and my copy of 10.3 that came with my brother's MacMini that I can't install. Frustrating...

IMac DV won't install new Operating System on erased HD

Hi all. My iMac recently failed on every boot up and as I only use it as a music jukebox (I have a 20" G5 iMac for other things), I thought I'd erase the Hard drive and reload Panther. It previously ran 10.3.9 very well.
The iMac boots up off the Panther CD and starts loading the system onto the Hard Drive, then about 3 minutes it gives the error "the installer has quit due to an unexpected error (exit code 0) , please restart your computer". It does this when trying to load Panther or Jaguar.
Not I am stuck, I have a HD which is recognised by the iMac but I can't load any operating system on. At start up without the Panther CD istalled, all I get now is the finder folder with a flashing question mark and apple face logo.
I am desperate.....any suggestions.....

Mike, thanks for the advice.
I did a futher test. I ran the Disk Utility at installation with the following results:
1) select Maxtor 76.34 MB, clicked "erase" (with install os9 drivers selected)
2) Got "setting up partition map", and "filesys on system" messages were both successful
3) Ran First Aid on the volume "Untitled" disk Verify Disk command says "The volume verified appears to be OK. Ran First Aid on "76.34GB Maxtor" and got the same result.
4) Continued with Install and got to "select a destination disk" and I selectd disc "untitled 76.3GB" then continue
5) Clicked Install.
6) Got the following messages: "Preparing the disk, preparing osx, preparing the base system, preparing essential system software, preparing the bsd subsystem then "you need to restart your computer" message.
It tends to be a different thing every time. Sometimes when I initially verify the volume or disc I get errors and have o do a repair. I get a message saying the repair has worked, but without a successful load result.
I guess I should be buying a new Hard Drive....
Will a 7200 rpm drive be ok in the iMac wrt heating issues (I cant get a 5400 any more).?
cheers

Role of S Partition in Installing New Operating System

Hello,
I've been taking a look on here and understand that the Q partition is for the backup to factory settings and the S partition is part of the start up system (working with a 2009 T400). I am looking to install Windows 7 and have no interest in keeping my XP system recoverable.
Therefore I can delete the Q partition but is there anything special I have to do in regards to the S partition? Or is it a plug and play situation once I put in the Win7 disk?
Essentially
-Can I delete the S: drive?
-If it remains partitioned, will it need to change in some way with the new OS?
-During Win7 set up which partition do I select to install on?
Solved!
Go to Solution.

Hello and welcome,
Since you don't intend to save anything let the Win 7 installer use the whole drive. It will partition appropriately.
(IIRC) When you get to the partitioning part of the install select advanced disk options and delete all the partitions. Then just let the install continue from there.

Can I install new operating system without wiping out all of my programs- some of which were free

Can I upgrade my OS without clearing out all programs such as Adobe Creative Suite, Office, etc as well as all files that I do not want to lose because many of the programs were free and do not have portable storage drive?

You can upgrade the OS without clearing out your programs or files, however that's no guaranty that those programs will continue to work in the new OS.
And if you plan to jump over operating systems, like going from 10.4 to 10.6 or 10.5 to 10.7 that that will require wiping the drive of all programs and installing the new OS fresh.
So perhaps you better start by telling us some details about your present hardware specifications, your computer model (like MacBook Pro 3,1) your OS X version, your RAM amount, your hard drive size, software you absolutely need, others that you can perhaps do without, and what and where you want to go etc. Also if you want to spend money and how much.
You can find out about your machine by Apple Menu>About this Mac>More information.
Your question is rather lacking on details, and people don't update their signatures so we can't go by that.

Hi @sam1211 ,
Thank you for visiting the HP Support Forums and Welcome. I have looked into your issue about your HP Pavilion dv6 Notebook and Bluetooth and HP Simplepass complications since doing a Windows upgrade. Here is a link to the HP Support Assistant. Just download and run the application. Just to make sure all drivers and software are updated as well.
Here is a document on troubleshooting and using Bluetooth if needed. Under the tips for finding a Bluetooth device, there is a section on making sure the wireless communication is turned on. This is an important section.
Here is another document with some great information about Bluetooth fixes.
Here is a link to troubleshoot the HP Simplepass software.
The HP SimplePass Identity Protection Software must be updated to v8.00.57 or later. Here is a link to download the latest. You will have to uninstall the old software.
Hope this helps you with the Bluetooth and HP Simplepass.
Thanks.

There is no opportunity to download it, Richo. Your best bet is to have an acquaintance in the USA, Latin America, or Canada order the recovery discs and ship them to you.

I recently installed the new operating system. iMovie doesn't seem to work the same as in Mountain Lion. I can't figure out how to burn a movie to a DVD. Has that feature been eliminated?

I am having difficulty figuring out how to burn my iMovie to a DVD. Has that feature been eliminated?

unbelievable... the amount of RAM is the issue... I found a post (http://forums.creative.com/creativelabs/board/message?board.id=soundblaster&message.id=8448) on an unrelated matter, but the user solved their issue under X64 by limiting the amount of RAM WinXP x64 was using by editing the boot.ini file.
The basis of the "trick" is to add " /maxmem=4096" to the end of your OS line, but I elected to copy the line and add it to a new entry so I could easily select which "mode" i wanted at boot.... like so...
multi(0)disk(0)rdisk(0)partition()\WINDOWS="Window s XP Professional x64 Edition" /noexecute=optin /fastdetect
multi(0)disk(0)rdisk(0)partition()\WINDOWS="Window s XP Professional x64 Edition - X-Fi tweak" /noexecute=optin /fastdetect /maxmem=4096
amazingly this solved my issue... but now my system properties only report 2Gb instead of 4Gb... unacceptable!

Can not connect to google on Mac mini or iPad, says Ido not have a certificate. This problem started after installing latest operating system

Cannot Connect to google on iPad or Mac. Mini says I do not have a certificate. What is the problem and how can I fix it.

I have Maverick on my iMac and haven't noticed any connection or any other issues. Also, that won't have any affect on your mobile devices.
Most likely an issue with your router or isp.
Try rebooting your modem and router (if applicable) by unplugging it for 5-10min.
At the same time, reboot mac and both/all mobile devices by pressing and holding both the home and sleep/wake buttons at the same time until the apple logo appears on the screen.
