I have an old, 2008 iMac. I just wiped the hard drive clean, 7 passes. Disc Utility then offers the option to reinstall the OS, which I selected. I got a window to "Install macOS Sierra, click continue," which I did. I then get a drop-down message: "To download and restore macOS, your computer's eligibility will be verified with Apple." I click "Continue." The drop-down menu disappears, and nothing happens; it will not advance to the next step. How can I get it to proceed?

If you can't find it, you can purchase a new one using the link below. Once you get the disk, boot off the DVD and run Disk Utility Verify/Repair Disk and Repair Permissions until you get no errors. Reformat the drive using Disk Utility/Erase Mac OS Extended (Journaled), then click the Option button and select GUID. Then re-install the OS.

Looks like El Capitan is the most recent I can install on this computer. But how can I get the installer file? One instruction told me to go to App Store, Purchased, and select El Capitan. But there I get an error message telling me I can't install El Capitan on this computer (the newer one I'm using to try to create the boot disk from).

I've found an old OSX installation DVD, from a 2010 MiniMac; can I use that? Unfortunately, my iMac's DVD drive died long ago, but I've got an external DVD drive. I tried to get it to read off of that by holding down the Option key during startup, but that had no effect. Will this installation DVD work, and if so, how can I get the iMac to read it off the external DVD drive?

I got a window to "Install macOS Sierra, click continue," which I did. I then get a drop-down message: "To download and restore macOS, your computer's eligibility will be verified with Apple." I click "Continue." The drop-down menu disappears, and nothing happens; it will not advance to the next step. How can I get it to proceed?

When I restart the computer, holding down the Option key when I hear the startup chime, first I get an image of a hard drive and and arrow. I press Return and it disappears, replaced by the Apple symbol, with the progress bar underneath. When the progress bar finally finishes, I get a grey screen; in the middle is a box, macOS Utilities, with 4 options: Restore from Time Machine backup; Reinstall mac OS; Get Help Online; and Disk Utility. If is select Disk Utility, it shows: Internal: WDC xxxx, with Macintosh HD underneath, and Disk images: Apple disk image Media, with OS X Base System underneath. I first selected WDC and partitioned it, but once that's done, I can't get to the Snow Leopard installer.

OK, I restarted and waited about 5 minutes, holding down the option key, but the image of the external DVD drive never appeared, only the image of the main hard drive. I even tried to "wake it up" by ejecting and reinserting the DVD tray.

If the old Mac doesn't recognize the CD/DVD drive, then you might have to acquire an external CD/DVD drive. There are a lot of cheap ones on the market. Just read reviews to see if they work on a Mac. Most do, but I'm sure there are some out there that will not.

Summary: This post tells you how to fix two common errors you may encounter when reinstalling Mac OS X or OS X, "A required download is missing." and "Can't download the additional components needed to install OS X."

You may receive a pop-up that says, "A required download is missing." or "Can't download the additional components needed to install OS X." when reinstalling the Mac operating system after formatting the startup disk. Based on the posts in Apple's community, these errors seem more common on older OSes such as OS X El Capitan, OS X Yosemite, Mac OS X Lion, etc.

When you get into Recovery mode through Command + R to reinstall OS X, you may get the notification "To download or restore your OS X, your computer's eligibility will be verified with Apple.". If you click on Continue, it displays a yellow triangle with the warning "A required download is missing."

To drive your Mac to search for an updated reinstall certificate online, you need to switch to Internet Recovery, which starts with a built-in ROM that allows your Mac to connect to the internet and download recoveryOS and bootstrap reinstalling OS X.

If your Intel Mac is manufactured from late 2011 onwards and runs Mac OS X 10.7 Lion or later, you can utilize Internet Recovery without extra software. Restart your Mac, then immediately press and hold Command + Option + R until the spinning globe appears. When Internet Recovery is loaded, you will see the OS X Utilities window.

Try clicking Disk Utility to erase your startup disk again, then tap on the "Reinstall OS X (macOS)" option to reinstall macOS/OS X. If you upgraded to macOS Sierra 10.12.4 or later, you get the latest macOS version compatible with your Mac. Otherwise, you reinstall the OS that came with your Mac or the closest available version. If that doesn't work, continue with step 2.

If your Mac was produced in early 2011 or earlier and runs Mac OS X 10.7 Lion or later, it doesn't have Internet Recovery in its ROM. In that case, you need to reinstall the operating system using a bootable USB installer.

It's possible that your Mac hard drive is failing or has other fatal disk errors stopping it from running the installation. To rule out the possibility, you need to check its S.M.A.R.T (Self Monitoring Analysis and Reporting Technology System) status in Disk Utility. Follow these steps:

If the S.M.A.R.T status reports no error, verifying and repairing your disk with the "First Aid" feature in Disk Utility is still advisable. Go through the steps below to repair file system errors that may lead to "A required download is missing." on Mac:

Once you've done with Disk Utility, try reinstalling the operating system in Internet Recovery again. If, for example, when reinstalling OS X Yosemite 10.10, "A required download is missing." recurs, move on to the next step.

As we mentioned before, receiving "A required download is missing." on Mac when reinstalling OS X El Capitan or other OSes is likely caused by the expired certificates. Another way to bypass the issue is to set your Mac'date previous to the expiry date of the certificates. For instance, you can turn the date back to when the OS was released.

Prepare a USB flash drive with at least 14GB of storage and another Mac compatible with the OS X you want to reinstall if the Mac with the missing download can't start up normally. Then use the following steps to reinstall OS X Mavericks or other versions without having the "A required download is missing." error:

Tips: If you can't select the USB as your startup disk or the USB stick shows as blank, you need to reset the NVRAM on your Mac. To do this, shut down your Mac, then turn it on and immediately hold down Command + Option + P + R. You can release the keys after the second startup sound, or the Apple log appears and disappears for the second time.

Similarly, you may get the message saying, "Can't download the additional components needed to install OS X." when reinstalling an older Mac operating system. Here are the solutions to try if you can't download the additional components needed to install Lion and other OSes:

Amazon EC2 registration requires you to have a valid phone number and email address on file with AWS in case we ever need to contact you. Verifying your phone number takes only a couple of minutes and involves receiving a phone call during the registration process and entering a PIN using the phone key pad.

Once you have set up your account and select or create your AMIs, you are ready to boot your instance. You can start your AMI on any number of On-Demand instances by using the RunInstances API call. You simply need to indicate how many instances you wish to launch. If you wish to run more than your On-Demand quota, complete the Amazon EC2 instance request form.

If Amazon EC2 is able to fulfill your request, RunInstances will return success, and we will start launching your instances. You can check on the status of your instances using the DescribeInstances API call. You can also programmatically terminate any number of your instances using the TerminateInstances API call.

If you have a running instance using an Amazon EBS boot partition, you can also use the StopInstances API call to release the compute resources but preserve the data on the boot partition. You can use the StartInstances API when you are ready to restart the associated instance with the Amazon EBS boot partition.

In addition, you have the option to use Spot Instances to reduce your computing costs when you have flexibility in when your applications can run. Read more about Spot Instances for a more detailed explanation on how Spot Instances work.

When you launch your Amazon EC2 instances you have the ability to store your root device data on Amazon EBS or the local instance store. By using Amazon EBS, data on the root device will persist independently from the lifetime of the instance. This enables you to stop and restart the instance at a subsequent time, which is similar to shutting down your laptop and restarting it when you need it again.

Alternatively, the local instance store only persists during the life of the instance. This is an inexpensive way to launch instances where data is not stored to the root device. For example, some customers use this option to run large web sites where each instance is a clone to handle web traffic.

It typically takes less than 10 minutes from the issue of the RunInstances call to the point where all requested instances begin their boot sequences. This time depends on a number of factors including: the size of your AMI, the number of instances you are launching, and how recently you have launched that AMI. Images launched for the first time may take slightly longer to boot.
