Can you manually eject a disk if you can't power on your computer?

Computer won't start up and the mouse solution doesn't work. Any other way to get a CD out of the drive?

If you have a mid 2011 machine it's covered by a 1 year warranty, take it in for service. You need power to eject a disc.

"Install Adobe Flash Player" is damaged and can't be opened. You should eject the disk image.

Attempting to install Flash player on a mac. System requirements are met; old versions uninstalled. I keep getting this error message "Install Adobe Flash Player" is damaged and can't be opened. You should eject the disk image.

Hi,

"Adobe Photoshop Lightroom 4.pkg" is damaged and can't be opened. You should eject the disk image.

After 3 different downloads (2 in Safari, 1 in Firefox) I still get this message when I try to open Lightroom package: “Adobe Photoshop Lightroom 4.pkg” is damaged and can’t be opened. You should eject the disk image. I have a feeling it has to do with 3rd-party software on my Mac OSX 10.8.2 - how do I get around that?

If you have already tried an alternate web browser then your next step would be to try an alternate Internet connection. Perhaps try a wired connection if you are using wireless for example.

"Adobe ColdFusion 10" can't be opened. You should eject the disk image.

Hello,
Dowloaded Coldfusion from the Adobe website, both with Safari as with Firefox
I want to install Coldfusion 10 on my Macbook. OS X 10.7.4 ( so not 10.8 ). When I double click the
.dmg file , I always get "“Adobe ColdFusion 10” can’t be opened. You should eject the disk image." error. Never had this before. I've read about setting security on 'non signed packages', but this applies to 10.8.
Is this a known issue ?
Thanks,
Dirk

Reinstalling Design Premium 5.5 on a Mac - error message "Install" can't be opened. You should eject the disk image.

Trying to reinstall Design Premium 5.5 on a Mac OSX 10.7.5 - once downloaded to my computer it will not install due to error message "Install" can't be opened. You should eject the disk image.
Thanks

no, redownload using a different browser from prodesigntools.com
if you follow all 7 steps you can directly download a trial here: Download Adobe CS5.5 Trials: Direct Links (no Assistant / Manager) | ProDesignTools
and activate with your serial number.
if you have a problem starting the download, you didn't follow all 7 steps, or your browser does not accept cookies.
the most common problem is caused by failing to meticulously follow steps 1,2 and/or 3 (which adds a cookie to your system enabling you to download the correct version from adobe.com).
failure to obtain that cookie results in an error page being displayed after clicking a link on prodesigntools.com or initiates the download of an incorrect (eg, current) version.

Can't install MAC OS X Lion - Macintosh HD "This disk cannot be used to start up your computer."

I downloaded OS X Lion this morning and when I went to install it I got a "Screen - Select the disk where you want to install OS X." -- Had two disk my Macintosh HD and my Time Machine (both are 1TB). The top and most important is the Macintosh HD (999.86GB - 739.75GB available states "This disk cannot be used to start up your computer". What do I need to do to install OS X Lion?

Create a Backup Lion Bootable 10.7 Disk
Purchaseand download Lion from the Mac App Store on any Lion compatible Macrunning Snow Leopard.
Right click on “Mac OS X Lion”     installer and choose the option to “Show Package Contents.”
Inside the Contents folder that     appears you will find a SharedSupport folder and inside the     SharedSupport folder you will find the “InstallESD.dmg.” This is     the Lion boot disc image we have all been waiting for.
Copy “InstallESD.dmg” to     another folder like the Desktop.
Launch Disk Utility and click the     burn button.
Select the copied “InstallESD.dmg” as the image to burn,     insert a standard sized 4.7 GB DVD, and wait for your new Lion Boot     Disc to come out toasty hot.
With this disc you can boot any Lion compatible Mac, and install10.7 just like you installed previous version of Mac OS X. You caneven use Disk Utility's Restore function to image your Lion boot discimage onto a external drive suitable for performing a clean installon a optical-drive-less MacBook Air, or Mac mini server.
If your using Mac's in a mission critical type environment or have third party hardware or software you must rely upon working correctly. It's advised to wait until all the bugs, driver updates, third party software updates and other issues are resolved before upgrading. This might take several months. Then if you do so, do one machine at a time and carefully test everything before full deployment.
It's also highly advised to backup all one's data either manually to a external powered drive in addition to TimeMachine and Hold option bootable Carbon Copy Clones etc.

The Mac SuperDrive built into your Mac is the Optical drive.
1. Insert your Windows DVD in Optical drive. Disconnect any external storage.
2. Insert a USB2 Flash drive. This will be used to hold the BC drivers.
3. Start BCA. Check the options to download software and Install Windows. You do not need to download Windows. The BCA will download the BC drivers to the USB.
4. Partition your drive.
5. You can see the Windows installer screens at https://help.apple.com/bootcamp/mac/5.0/help/#/bcmp173b3bf2.

Can't install: "this disk cannot be used to start up your computer"

After making sure that my current startup disk for 10.5 was imaged to another hard drive, I inserted the Snow Leopard install disk and double-clicked the Install icon. Everything worked fine till I got to "Select the disk where you want to install Mac OS X." All of the disk partitions had warning triangles, including the one for my original startup disk, which has worked perfectly for the 10.5 pre-installed on my new iMac (identifier 9,1). When I click on the icon for this drive, the warning message below states "Mac OS X cannot be installed on 'iMac HD', because this disk cannot be used to start up your computer." Obviously that's not true, since that's where the OS is installed. No other programs were running except Finder.
I used Disk Utility to check the disk and repair permissions: no change in the installation program's message. I quit the installation program and reinserted the DVD. It certainly does a lot of churning of the DVD before you ask it to do anything. With all external hard disks disconnected, it still gives the same error message.
Where do I go from here? I thought Snow Leopard was "The world's most advanced operating system. Finely tuned." It can't even install itself and recognize a bootable internal hard drive on an iMac.

How did you partition this drive, if you did that? Does it contain start up or utility partitions for any other OS (for instance Linux)? There have been reports that the "cannot be used to start up your computer" message will appear if a third party utility was used to create a 'triple boot' system or such, apparently because SL is picky about the format GUID partition scheme table info & how partitions are allocated space on the drive by other formatting/partition methods.
For some users with these partitions, the fix has been as simple as "tickling" (slightly changing) the partition size of some partition with Disk Utility, which apparently updates the GUID partition scheme table info so that the SL installer accepts it as safe to use with SL.( In this sense, the message may be trying to say the installer thinks the disk can't be used to reliably start up your computer with SL, not in general.)
See the discussions topic Cannot install Snow Leopard over 10.5.8 for more about this.

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

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.

Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled. This shows up even when I am not connected to a USB. what do you think the problem is?

Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled. - This is what shows up sometimes even when no USB is connected. What could be the reason?

Try a different USB cord, seen this many many times, its highly likely a damaged USB cord.
Restart the computer to redefine Port definition. If still a problem

How to I get rid of pop up user account control "do you want to allow the following program to make changes to your computer" I have windows 7 professional.

I keep getting an annoying pop up the says "User Account Control" "Do you want to allow the following program to make changes to your computer"
== This happened ==
Every time Firefox opened
== Two days after I downloaded Firefox and set as my default browser.

Check that you do not run Firefox as Administrator.
Right-click the Firefox desktop shortcut and choose "Properties".
In the Compatibility tab, make sure that Privilege Level: "Run this program as Administrator" is not selected.
You also need to check the Properties of the firefox.exe program in the Firefox program directory.
If you can't make the changes then you need to start Windows Explorer as Administrator.

None of that worked for me. And I don't think disabling UAC is a good idea at least if it's a work computer rather than my own.

Can you manually eject a disk if you can't power on your computer?
