My friend was wiping my Mac so I could sell it and I’m pretty sure they’ve deleted the start up disk? It’s not letting me reinstall the OS on a recovery startup.
Many Mac users like to make a bootable installer drive for installing OS X El Capitan, whether for performing a clean install, or for making it easier to install OS X 10.11 onto multiple Macs. We will walk through creating a bootable install flash drive from OS X El Capitan with the final public version. The OS X El Capitan Desktop after a brand-spanking-new installation of OS X. Blue/black/gray screen of death: If any of your hardware fails when it’s tested, you may see a blue, black, or gray screen. Some older Macs played the sound of a horrible car wreck instead of the chimes, complete with crying tires and busting glass.
She wonders about a fix. There are a couple of options with an erased partition.
Because Recovery didn’t work, the fastest way to install fresh is to make or borrow a macOS installer on a USB flash drive or a disk drive. We have instructions for making a bootable installer with macOS Sierra (as well as archived versions for several previous releases). You need at least an 8GB flash drive. The article includes instructions on obtaining the installer, which might involve you having to use someone’s else Mac to download it, if you don’t have a replacement Mac on hand yet.
But if you can’t get access to another Mac or the necessary drive, it’s still possible to use a different Recovery mode on all recent Macs, dating back to 2010. Normally, you can start up a Mac while holding down Command-R to boot into what Apple now calls macOS Recovery. That allows you to run Disk Utility, reinstall or wipe and install the system, access Terminal for command-line functions, and so on. In that mode, when you choose to reinstall without erasing the drive, my recollection is that Recovery looks for the current OS system installer on your startup disk in the Applications folder, and uses that. (Apple doesn’t document that, and I haven’t had to test that for years.)
Failing finding it, Recovery downloads the currently installed version of macOS (or OS X), which is about 5GB. When complete, it installs it and reboots, and places the installer in the Applications folder.
However, there’s yet another option: macOS Recovery over the Internet, which requires either a Mac model released in 2012 or later, or most 2010 and 2011 models with a firmware upgrade applied. There, the Mac reaches out over a Wi-Fi or ethernet connection to download the relatively modest Recovery software, which then bootstraps the download of the full macOS installer.
Apple says Internet-based Recovery should happen automatically on supported models, and you should see a spinning globe when that mode is invoked while the download occurs. However, if you have normal Recovery installed and it refuses to install macOS for some reason, you can manually invoke Internet Recovery.
While Command-R at startup always installs whatever the most recent version you installed on your Mac, holding down Command-Option-R brings down the very latest compatible version that can be installed. Apple also offers Shift-Command-Option-R, which installs the version of OS X or macOS with which your computer shipped, or the next oldest compatible system still available for download.
(Apple just changed this behavior with 10.12.4, but if you’re using Internet Recovery for a clean install on an erased drive, the new behavior should be active as it will be pulled from the version of Recovery that’s bootstrapped from Apple’s servers. The pre-10.12.4 option is simply Command-Option-R, but it acts like the new Shift-Command-Option-R, installing the shipped OS or the oldest compatible version.)
Apple recommends the Command-Option-R option as the only safe way to reinstall a Mac with El Capitan or earlier versions of macOS if you want to be sure your Apple ID doesn’t persist even after erasure.

With time, your Mac may get inundated up with multiple files: video, audio, pictures, documents, etc., thereby gradually eating up disk space. If necessary action isn't taken to clean up the clutter, it may ultimately lead to a warning message: Your startup disk is almost full. Don't worry, this is normal and can be rectified.
Finding Out Why Your Startup Disk is Full on Mac OS X
To determine the reasons why your startup disk is full, follow these steps:- Hit the Apple icon at your screen's top-left corner.
- Select 'About This Mac'.
- Hit Storage.
Top 10 Ways to Clean Startup Disk on Mac OS X (El Capitan)
Let's cruise through the top 10 methods to clean your startup disk. Having gone through the steps, you may learn more about your Mac and also discover a few new ways to fix the issue.
1. Empty out the Trash
In Mac OS X, almost every deleted file or document heads to the Trash Bin. Bypassing Trash is often not possible when deleting files permanently. Trash Bin files could either be individually deleted or emptied at once by right-clicking the Trash icon. However, some of the erased files may still leave their footprints. Follow these steps to delete the files completely:
Create El Capitan Startup Disk
- As aforementioned, right-click the icon.
- Now hit the button 'Command' on your keyboard.
- The icon's Empty Trash will now get converted to Secure Empty Trash. Clicking this option will permanently delete the entire Trash Bin.
2. Clean up your Downloads, Movies and Music folders
It's important to frequently check and clean up your download, movie and music folders. Most download files aren't needed or used after some time. You can move the downloaded files to an external hard drive or the Documents folder. Before cleaning up the contents, organize the space by Date Last Opened or Date Modified. This will help you locate files that haven't been used much since their download.
The Movies folder is where you probably have a few hundred gigabytes of digital content. Click the Movies folder and press Command-I. Look at the pop-up that shows up at your window's top right to find out the folder's space consumption. Clean up the space or move the files to an external hard disk. The same process applies to cleaning the Music folder too.
3. Clean your Desktop
Having the desktop cluttered with multiple apps and files will slow down your Mac. The reason being every icon consumes some RAM.
However, the solution is pretty straightforward. Clean up the desktop and don't store files there. If you need to store temporary files, create a dedicated folder.
4. Remove unnecessary applications
Safely and permanently remove or uninstall apps and their preferences, components, log files, etc. Sending them to the Trash Bin isn't mission completed. To uninstall, choose an application.
This is a disk cleaning aspect with which CleanMyMac 3 will come quite handy. To get the job done, launch the application, hit Uninstaller, choose the application to be removed and click Uninstall.
5. Delete old iTunes Library backups
Recent iTunes versions generate existing iTunes Library file's backup each time the iTunes app is updated. Once you're happy with the performance of a current iTunes update, delete the old files by heading to the previous iTunes folder.
6. Clean up your iPhoto library
The iPhoto app has its dedicated recycle bin. To get started, choose files you'd like to get rid of. These may include bad or inadvertently clicked photos. Service copies also must be booted out. These are copies of original images that were altered. The original image is copied and stashed away safely. Needless to say, these copies eat up considerable disk space.
The folders Master, Original, Modified and Preview must be checked to determine if there're copies. To access the folders, open the Finder window and head to the Pictures folder. Press Ctrl and click the iPhoto library and choose Show Package Contents. You must now manually go through the folders and find out copies with altered original copies.
This could be cumbersome if you've got a huge photo repository. With CleanMyMac 3, the cleaning will be safer and faster. The cleaning app scans the library and only gets rid of the duplicates. CleanMyMac3 is highly recommended during such scenarios since critical or wrong files once cleaned up cannot be recovered.
7. Get rid of localization files
If you chose the option Easy Install during Mac OS X installation, several localization files for different languages get installed. The files allow the OS X interface to show up in multiple languages. To delete them:
- Open Finder.
- Head to Applications.
- Press Ctrl and left-click an application simultaneously.
- Choose 'Show Package Contents'.
Now, head to Resources under Contents and locate files ending with .lproj. There's a specific language prefix before the file name. For instance, German language files will show up as de.lproj. Delete the unwanted language files.
You could easily get rid of these files using a third-party alternative like CleanMyMac 3. You'll only require a click and no surfing through multiple folders to get the job done.
8. Remove old iOS backups
Backups can consume excessive space. You could locate and eliminate them by:
- Opening the Finder window.
- Hitting 'Go' in the menu pane.
- Choosing 'Go to Folder'.
- And heading to the Backup folder.
Clean up all the outdated, old backups.

9. Clean up cache files on your Mac
Caches are non-permanent files that help increase the speed of specific tasks. However, with time, the files could get bloated.
To get cleaning, click the Finder application. Then, long press the Option key and hit the menu bar's Go option. This should expose the typically hidden Library folder. You would find your caches folder in the Library folder.

Also, there are several third-party applications, such as CleanMyMac 3, which help make the cleaning process much simpler and hassle-free.
10. Remove old iOS device backups

How to Prevent Startup Disk Full on Mac in the Future
The biggest disk space-hogging element on your Mac is always those huge multimedia files and documents. These could be cumbersome to clean if done manually. However, a software application like CleanMyMac 3 will carry out the task within minutes. Moreover, the software will also warn you whenever the disk space is nearing exhaustion, helping you stay on top of space utilization, always.
To make accessing and monitoring the software features easier, a fresh menu bar is available that keeps track of memory usage, free space, and existing trash size. Customer alert standards can be set in software preferences, which notifies you whenever disk space is extremely low or the bin size is too high. This is a helpful feature for people with limited disk space on their Macbooks.
