What to Do When the macOS Installation Couldn’t Be Completed
hi!! i got given a 2011 macbook air that was working fine, until i asked my friend to try and wipe it. i'm not sure what they did, but i know the disk has been erased via the disk utility route. this is the problem: when i turn it on normally, it comes up with the folder with a question mark symbol. i can't proceed any further. when i turn it on holding command + R, it says "starting up internet recovery" and then takes about 15 minutes for that to load. then, it comes up with the screen w/ 4 options (time machine, reinstall macOS, find help online, disk utility). i've gone on disk utility and made sure its erased (i didn't erase the "mac OS X base system") and when i check w the repair function, it says its all good. it's just when i go to reinstall macOS (lion), it automatically jumps to like, 99% of the loading/progress bar, and says 2,48374,48539 (some ridiculously long number like that) hours to go, then after about 30 seconds, it comes up with the error "Can't download the additional components needed to install OS X" i've made sure i'm connected to wifi each time btw. i've also tried rebooting it using command + R + option, and it takes me to download macOS high sierra instead of lion. it does the whole download but it's been stuck at 2 minutes for.... ages please help!!!! also, i'm no tech wiz at all so if you could explain in idiot-friendly terms it'd be much appreciated. xxxx 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. Table of Contents:
Fix 'A required download is missing.' on MacWhen 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." If that happens, here are the steps you should try to get rid of "A required download is missing." on Mac:
Step 1: Restart in Internet Recovery Mode.Suppose you can't reinstall macOS with Command + R, which starts your Mac from the built-in macOS Recovery System. That's likely because your laptop's certificate for Mac OS X reinstalls has expired. 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. Note: The original name of the Mac operating system is Mac OS X, but Apple shortened the name to OS X in 2012, which then changed it again to macOS in 2016 to align with iOS, watchOS, and tvOS. Step 2: Check your startup disk's SMART status with Disk Utility.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. Step 3: Change your Mac's date using Terminal.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. Fix "A required download is missing." on MacBook Pro 2012 and other Mac models:
Note: If sudo date [month][day][hour][minute][year] isn't working, try the command again without sudo. If you reinstall OS X Mavericks but still get "A required download is missing.", keep trying with the next step. Step 4: Reinstall OS X from a bootable installerIf you keep getting "A required download is missing." on your MacBook Pro 2012 when reinstalling OS X from macOS Recovery, try performing the task from an external bootable installer. 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: On another functional Mac:
On the Mac that you want to reinstall OS X:
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.
