Can't Install OSX Yosemite on iMac Mid-2009 Stuck - No Recovery Partition PLEASE HELP

I had an old iMac Mid-2009 2GB on OSX Lion, which had been kept away in the garage for a while. Pulled it out, ran Lion fine. It was going to be set up as a new computer, so I downloaded OSX Yosemite, planning to wipe and re-install after installation. Took a lot longer than I expected. After a while, the apple logo progress bar froze. I googled it and many people said just to wait it out, it could take up to 12 hours. 1 week later, still there. Fairly confident that nothing was going on on the hard drive. I reset the PRAM, didn't help. So I tried another fix I found which involved booting into the recovery partition. Guess what, no recovery partition . So finally I went to the trouble of creating an install usb. Booted fine, so I went into Disk Utility to erase my hard drive and re-install. But guess what, I couldn't! Can somebody please help! Or is this iMac stuffed?

Finally figured out the solution. My internal HDD appears to be not working after that faulty Yosemite installation. Just got a fast external HDD, plugged it into the iMac. Booted from the USB, went into Disk Utility and formatted it as Mac OS Extended (Journaled) in GUID. Installed and got up an running fine. Finally fixed this after 3 weeks! Hopefully this will help anyone that has the same problem.

I can't install OneDrive on my iMac (mid 2010)

Hello,
I'm trying to install OneDrive on my iMac (OS10.9.2) and the process keeps stalling at the point where it asks me to choose the OneDrive folder location. I let the process continue for about 10 minutes or more until I force-quit it (because the application is not responding).
I've tried several times to install OneDrive and it continues to stall at the point where I'm asked to choose the OneDrive folder. I've moved the "com.microsoft.OneDrive-mac" folder to the desktop thinking the settings are corrupt and force OneDrive to install new settings. Again, the same problem - the installation stalls at the point where I'm asked to choose the OneDrive folder location.
I'm puzzled by one thing though. There is no OneDrive folder in my Finder. Is that why the installation is stalling because it can't find the OneDrive folder in my Finder?
Any suggestions?

Hello Babow,
Yes, I looked at the FAQ there first and asked my question there. I'm waiting for a reply.
I then found a link back here on Apple Support Communities with a possible solution. But the solution did not work. So, I posted my question here as well.

Can i install 1TB to macbook pro mid 2009

hello,
i have a macbook pro mid 2009, 2.66ghz 2 duo and i want to install a new HDD
can i install 1TB??
what is the biggest HDD storage that the notebook can handle??
and how do i install my mac os x to the new HDD?
thank you.

The MacBook Pro's take 2.5" SATA hard drives. If you are going to replace the drive, now would be the time to upgrade to a 7200rpm drive; about the largest capacity you will find is 750GB. Also, since this will be your main hard drive, stay away from any green or blue drives; the supposed energy saving features will also reduce performance. May I suggest looking at OWC for their recommendations about hard drives for your specific model MBP.
You install OS X via the recovery DVDs that came with your MBP. One is for OS X, the other contains the Apple applications (iLife, etc). Of course, that will install the version of OS X that originally came with your MBP (a 2009 MBP probably came with Leopard 10.5). If you don't have the recovery DVDs, or want to install a later version of OS X, then I suppose you will need to purchase a Snow Leopard DVD and install that before upgrading to Mt. Lion.

Yosemite Upgrade - iMac mid-2011 - Stuck on white progress bar screen at about 50%

I have a mid 2011 iMac. I started the upgrade to Yosemite about 4 hours ago. For the last 3 and 1/2 hours it's been "stuck" at the white progress bar screen at about 50%. I hear the harddrive occasionally do reading/writing, but it isn't doing a lot just a tiny bit. I've seen others post across the net with similar situations, but no solutions. I'm willing to wait, but would love to know if it's actually proceeding or simply in some infinite loop.
Anyone know how to tell if it's in a loop or proceeding?
Anyone have any ideas on things to try?
I really don't want to try and interrupt the upgrade, but it doesn't appear it's going to complete.
Ideas?
Thanks for any help you all can provide.
Perry

This worked for my MBP 17" mid-2010 after 10 hours of minor panic watching progress bar stuck at 50%:
Reboot and hold SHIFT key to go into Safe Mode and keep holding that SHIFT key.
*Patience is the key to the Shift key*
Keep the Shift key down.
Do not let go of Shift key until you go to Italy when the computer does its Venetian blinds thing and goes into Safe Mode.
Check whether you have any login items. Do this via via Sys Preferences > Users & Groups
It is going to be slow. You are in SafeMode.
Remove any login apps.
Run any updates for Yosemite (e.g. Pages, Numbers, Keynote) within Safe Mode.
Reboot.
Remember, YMMV

My imac g5 is stuck on grey screen, please help :(

it started with the **** spinning wheel that wouldn't come unstuck, i had to shut down from the start button at the back. i restarted & now comes to grey screen, then the folder with '?' icon blinks. i put install disk and manage to try repair disk through disk utility, it said it couldn't repair some files(i 4got to take note...idiot). i figured to try archive/re install but it failed. i restarted and it managed to get to the desk top, so i used cocktail to do general house clean. i left and came back in 15min and the imac was shutdown, i powerd back up and now its just grey no folder'?' icon....nothing. i have pram 'd it still no go. has it bricked up?

Your drive is dying, back up now and then get a new one. Daddy Paycheck is absolutely correct.

Can't system restore from recovery partition, please help!

To start my info is: HP MINI 210-1003sa I have tried accessing recovery manager from the start menu, also tried accessing it by pressing f8, repair computer and f11 system restore isn't lit up as an option to click. It says my netbook has no recovery partition yet when I go to my computer drive D is the recovery partition. I have also downloaded the hp program that creates a bootable system restore USB stick but when I boot from it it just loads up windows. I really need to reset to factory settings ASAP, please help.

Hi Mike:
The second chapter of this saga.
I did order the recovery USB.
I did what it was asking and wiped out the HDD clean.
But the system is still unstable.
It took a very long time to configure itself. Several times I had to run the process again because it would either not boot or it would be just sitting there at the attached screen.
Sometimes it would go to Win8 boot window, but then suddenly come back to the same screen.
It seems that HDD is completly out. What is the warranty on the HDD? This laptop is just two years old.
And a side note: we had to send it for repairs twice already for monitor issues; the keyboard is not flat; there are some loose parts inside. I really expected better quality from such a reputable brand as TOSHIBA.
-Ilya.

Since installing OSX 10 my iMac randomly shuts down and restarts. I can not determine why this is happening. Any ideas?

Since installing OSX 10, my iMac randomly shuts down and restarts. I can not determine why this is happening. Any ideas?

1. This is a comment on what you should and should not do to protect yourself from malicious software ("malware") that circulates on the Internet. It does not apply to software, such as keystroke loggers, that may be installed deliberately by an intruder who has hands-on access to the victim's computer. That threat is in a different category, and there's no easy way to defend against it. If you have reason to suspect that you're the target of such an attack, you need expert help.
If you find this comment too long or too technical, read only sections 5, 6, and 10.
OS X now implements three layers of built-in protection specifically against malware, not counting runtime protections such as execute disable, sandboxing, system library randomization, and address space layout randomization that may also guard against other kinds of exploits.
2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files, and to block insecure web plugins. This feature is transparent to the user, but internally Apple calls it "XProtect." The malware recognition database is automatically checked for updates once a day; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders.
The following caveats apply to XProtect:
It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets.
It only applies to software downloaded from the network. Software installed from a CD or other media is not checked.
As new versions of OS X are released, it's not clear whether Apple will indefinitely continue to maintain the XProtect database of older versions such as 10.6. The security of obsolete system versions may eventually be degraded. Security updates to the code of obsolete systems will stop being released at some point, and that may leave them open to other kinds of attack besides malware.
3. Starting with OS X 10.7.5, there has been a second layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Software certified in this way hasn't necessarily been tested by Apple, but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. That may not mean much if the developer lives in a country with a weak legal system (see below.)
Gatekeeper doesn't depend on a database of known malware. It has, however, the same limitations as XProtect, and in addition the following:
It can easily be disabled or overridden by the user.
A malware attacker could get control of a code-signing certificate under false pretenses, or could simply ignore the consequences of distributing codesigned malware.
An App Store developer could find a way to bypass Apple's oversight, or the oversight could fail due to human error.
For the reasons given above, App Store products, and other applications recognized by Gatekeeper as signed, are safer than others, but they can't be considered absolutely safe. "Sandboxed" applications may prompt for access to private data, such as your contacts, or for access to the network. Think before granting that access. Sandboxing security is based on user input. Never click through any request for authorization without thinking.
4. Starting with OS X 10.8.3, a third layer of protection has been added: a "Malware Removal Tool" (MRT). MRT runs automatically in the background when you update the OS. It checks for, and removes, malware that may have evaded the other protections via a Java exploit (see below.) MRT also runs when you install or update the Apple-supplied Java runtime (but not the Oracle runtime.) Like XProtect, MRT is effective against known threats, but not against unknown ones. It notifies you if it finds malware, but otherwise there's no user interface to MRT.
5. The built-in security features of OS X reduce the risk of malware attack, but they're not absolute protection. The first and best line of defense is always going to be your own intelligence. With the possible exception of Java exploits, all known malware circulating on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "Trojan horses," which can only have an effect if the victim is duped into running them. The threat therefore amounts to a battle of wits between you and the malware attacker. If you're smarter than he thinks you are, you'll win.
That means, in practice, that you always stay within a safe harbor of computing practices. How do you know what is safe?
Any website that prompts you to install a “codec,” “plug-in,” "player," "extractor," or “certificate” that comes from that same site, or an unknown one, is unsafe.
A web operator who tells you that you have a “virus,” or that anything else is wrong with your computer, or that you have won a prize in a contest you never entered, is trying to commit a crime with you as the victim. (Some reputable websites did legitimately warn visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
Pirated copies or "cracks" of commercial software, no matter where they come from, are unsafe.
Software of any kind downloaded from a BitTorrent or from a Usenet binary newsgroup is unsafe.
Software that purports to help you do something that's illegal or that infringes copyright, such as saving streamed audio or video for reuse without permission, is unsafe. All YouTube "downloaders" are outside the safe harbor, though not all are necessarily harmful.
Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website. If it comes from any other source, it's unsafe. For instance, if a web page warns you that Flash is out of date, do not follow an offered link to an update. Go to the Adobe website to download it, if you need it at all.
Even signed applications, no matter what the source, should not be trusted if they do something unexpected, such as asking for permission to access your contacts, your location, or the Internet for no obvious reason.
"FREE WI-FI !!!" networks in public places are unsafe unless you can verify that the network is not a trap (which you probably can't.) Even then, do not download any software or transmit any private information while connected to such a network, regardless of where it seems to come from or go to.
6. Java on the Web (not to be confused with JavaScript, to which it's not related, despite the similarity of the names) is a weak point in the security of any system. Java is, among other things, a platform for running complex applications in a web page, on the client. That was always a bad idea, and Java's developers have proven themselves incapable of implementing it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been to a Windows-style virus affecting OS X. Merely loading a page with malicious Java content could be harmful.
Fortunately, client-side Java on the Web is obsolete and mostly extinct. Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice. Forget about playing games or other non-essential uses of Java.
Java is not included in OS X 10.7 and later. Discrete Java installers are distributed by Apple and by Oracle (the developer of Java.) Don't use either one unless you need it. Most people don't. If Java is installed, disable it — not JavaScript — in your browsers.
Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a task on a specific site, enable Java only for that site in Safari. Never enable Java for a public website that carries third-party advertising. Use it only on well-known, login-protected, secure websites without ads. In Safari 6 or later, you'll see a lock icon in the address bar with the abbreviation "https" when visiting a secure site.
Follow the above guidelines, and you’ll be as safe from malware as you can practically be. The rest of this comment concerns what you should not do to protect yourself.
7. Never install any commercial "anti-virus" or "Internet security" products for the Mac, as they all do more harm than good, if they do any good at all. Any database of known threats is always going to be out of date. Most of the danger is from unknown threats. If you need to be able to detect Windows malware in your files, use one of the free anti-virus products in the Mac App Store — nothing else.
Why shouldn't you use commercial "anti-virus" products?
Their design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere.
In order to meet that nonexistent threat, the software modifies or duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability, bugs, and poor performance.
To recognize malware, the software depends on a database of known threats, which is always at least a day out of date. Most of the real danger comes from highly targeted "zero-day" attacks that are not yet recognized.
By modifying the operating system, the software itself may create weaknesses that could be exploited by malware attackers.
8. An anti-malware product from the App Store, such as "ClamXav," doesn't have these drawbacks. That doesn't mean it's entirely safe. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so will corrupt the Mail database. The messages should be deleted from within the Mail application.
An anti-virus app is not needed, and should not be relied upon, for protection against OS X malware. It's useful only for detecting Windows malware. Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else.
A Windows malware attachment in email is usually easy to recognize. The file name will often be targeted at people who aren't very bright; for example:
♥♥♥♥♥♥♥♥♥♥♥♥♥♥!!!!!!!H0TBABEZ4U!!!!!!!.AVI♥♥♥♥♥♥♥♥♥♥♥♥♥♥.exe
Anti-virus software may be able to tell you which particular trojan it is, but do you care? In practice, there's seldom a reason to use the software unless an institutional policy requires it.
The ClamXav developer won't try to "upsell" you to a paid version of the product. Other developers may do that. Don't be upsold. For one thing, you should not pay to protect Windows users from the consequences of their choice of computing platform. For another, a paid upgrade from a free app will probably have the disadvantages mentioned in section 7.
9. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services. Disable any services you don't use in the Sharing preference pane. All are disabled by default.
10. As a Mac user you don't have to live in fear that your computer may be infected every time you install software, read email, or visit a web page. But neither should you assume that you will always be safe from exploitation, no matter what you do. The greatest harm done by security software is precisely its selling point: it makes people feel safe. They may then feel safe enough to take risks from which the software doesn't protect them. Nothing can lessen the need for safe computing practices.

I have installed FCPX on my iMac (mid 2007) with a video ATI Radeon HD 2600 Pro 256 MB. Tis does not meet the minimum requirements. It seems to be ok but what kind of problems can I expect ?

Hey Luis. I not only remember…I still have mine (OS 9)! Works perfectly well…for some things; just need to be selective about what I ask it to do. (Also have its big brother Pismo running Tiger, which is still an extremely competent machine.) When I take them out of their cases, I'm still amazed at the G3's build quality.

Can't install OSX Mountain Lion, on the disk selection screen i cant select the Macintosh HD to install OSX giving a message (This disk cannot be used to start up your computer).only have one disk to select and my partition map scheme is GUID partition

just bough OSX Mountain Lion, my laptop operating with v10.6.8. Can't install OSX Mountain Lion, on the disk selection screen i cant select the Macintosh HD to install OSX giving a message (This disk cannot be used to start up your computer).only have one disk to select and my partition map scheme is GUID partition table. 24.44gb disk available.

Verify your computer can run Mountain Lion:
Upgrading to Mountain Lion
To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
     OS X Mountain Lion - System Requirements
       Macs that can be upgraded to OS X Mountain Lion
         1. iMac (Mid 2007 or newer) - Model Identifier 7,1 or later
         2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) - Model Identifier 5,1 or later
         3. MacBook Pro (Mid/Late 2007 or newer) - Model Identifier 3,1 or later
         4. MacBook Air (Late 2008 or newer) - Model Identifier 2,1 or later
         5. Mac mini (Early 2009 or newer) - Model Identifier 3,1 or later
         6. Mac Pro (Early 2008 or newer) - Model Identifier 3,1 or later
         7. Xserve (Early 2009) - Model Identifier 3,1 or later
To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.
Open Disk Utility and verify the drive is partitioned using GUID and formatted Mac OS Extended, Journaled. If it is then do this:
Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
Now try installing Mountain Lion.

please tell which version of OSX 10.6 can be install in the above imac

First please don't post your serial number in a public. You should be able to install Mac OS X 10.6 on your system. The DVD you are using must be the original that came with the computer before it will work. What version of Mac OS X do you have on your system. I am thinking it is a higher version then 10.6.2.

Instal OSX Yosemite

I want to instal OSX Yosemite but told I can't

Check that your computer is compatible with Mountain Lion/Mavericks/Yosemite.
To check the model number hold down the option/alt key, go to the Apple menu and select System Information.
Mac Pro (Early 2008 or newer) model number 3,1 or higher

How can i install osx now ?

I clean my disk totally by disk utility and now nothing comes up when holding option key. After a while this text comes with a black background, "No Bootable Device -- insert boot disk and press any key".
I think I erase everything, even boot settings!!!
Now, How can i install OSX now on my iMac?

What is the exact iMac model you have, please? If your model can run Snow Leopard then you need to install Snow Leopard from your installer discs. Snow Leopard must then be upgraded to 10.6.8 so you can upgrade to the version of OS X you had installed from the App Store.
