Install Macos El Capitan From Usb
Sacha Weakland
I just had the weirdest thing happen. I made a bootable USB drive with the El Capitan installationfor my 2013 13" MacBook Air. When I boot the USB to the El Capitan installation, everything goes through, but for some reason I end up with Yosemite instead of El Capitan... Bizarre! Somehow during the install of El Capitan it decides to switch and install Yosemite instead of El Capitan. Can anyone tell me what's going on here?
I select to install Mac OS X El Capitan to the internal SSD. Again, I am verifying it is in fact installing to the internal SSD, and the screen says "El Capitan" on the screen through the install process.
After 15 mins or so, the MacBook reboots and then automatically starts installing MacOS X again, all automatically, just a progress bar and the Mac OS X logo on the screen. However, this time the screen does not say El Capitan as it did before. It just has a the Mac OS X logo (the big X logo inside the circle). Then it takes about another 15 to 20 mins, and then reboots one more time.
I repeated this process 3 times today just to verify I wasn't going crazy or missing something, and it went exactly as I described. The last time I did it, I had downloaded a new Mac OS X El Capitan installation package from Apple and once again formatted and recreated the USB stick, and still the same bizarre thing happened.
So now that Yosemite is up and running, I then open that same USB drive in Mac OS and start El Capitan installation once again while Yosemite is running, and then it upgrades Yosemite to El Capitan successfully with no problem. However, using the same package, I cannot install El Capitan by booting the USB from scratch.
I have Googled this and it seems I am the only one with this bizarre thing happening. Does anyone have any clue why I can't install El Capitan from scratch? I can only get El Capitan by upgrading Yosemite.
Hi @verasme from experience what i've used to make bootable OS X disks is a tool called DiskMaker X, It uses the "Install OS X El Capitain" from your /Applications folder which you've downloaded from the App Store, and takes about 10-15 minutes to create a bootable disk without the hassle.
But seriously, would it kill Apple (and for that matter any/all installer app makers) to have a version file somewhere and to display during the install on a corner of the screen exactly what version/build is being installed?
I'm sorry I don't have anything intelligent to offer in response to this oddness. You're erasing the whole drive not just the previous OS volume (i.e. from the Partitions tab select a new partition scheme) - because all I can think is you're somehow getting redirected to a Yosemite recovery partition. Make sure you don't have an active internet recovery session on your network!
Hi @verasme I've had this exact same issue happen to me multiple times. I was able to resolve this problem by making a few changes to my OS upgrade process. Below you can find the steps that I take when I upgrade OS X using a USB drive. Let me know if you have any issues.
What is surprising about this, is that during the El Capitan installation, the agreement screen and the setup screen, they all say OS X El Capitan, and I did this multiple times to confirm I wasn't making a mistake. How can this be the Yosemite recover partition or some "renamed" Yosemite install if everything I am looking at clearly says "El Capitan" 10.11 during the install? The only thing I am suspecting is that "El Capitan" package contains a copy of Yosemite built-in as some form of fall-back mechanism for certain devices that are incompatible with El Capitan, and for some odd reason, maybe a bug in the installation, this El Capitan package is reverting to Yosemite. That's only my speculation from knowing how Apple can sometimes pull "secret weapons" out of nowhere. LOL
@Valenzuela , Typically I would boot from the USB by holding the Option key, and then I open Disk Utility from there. I then format the internal SSD and then quit the Disk Utility which brings me back to the main menu. At that time, I select to install Mac OS X without rebooting. Next time, I will try rebooting after formatting.
By the way, if you've used the Disk Utility that comes with El Capitan installation, you'll notice the interface is quite different than the one that comes with Yosemite. So not only do I see the installation says "El Capitan" during the install, it also comes with a newer version of the Disk Utility.
@verasme, Try first booting using control + R and delete the partition. Reboot and hold down option to install El Capitan. What you just mentioned was exactly how I encountered it and it puzzled me because I've always used the previous method of holding down option and never had any issues during upgrades.
After some time researching this I found an article from Apple with the new documented steps and that's what I've been using since then. FYI - I just tried to upgrade a Yosemite Mac Mini to El Capitan with no internet connection using just "Option" and the steps you followed and it brought me back to Yosemite after the upgrade "Completed". The Disk Utility interface was also the El Capitan GUI just like you described.
You have 2 lines (you and everyone else) that I do not know how to format. I must be the dumbest guy on the planet because no one else posts how either. --applicationpath --volume. It is so frustrating I wish examples would be just that, examples, exactly what typed when you hit enter. Not --volume with no instructions on how to format that info. It may seem like a given to the geeks and gurus but to us little guys just trying to scratch out an answer at home on a Saturday night it is maddening.
@Frustr-As-Hell see if this helps. I have an 8 GB USB flash drive named ElCapitanInstaller that I will be turning into the installer. The drive is formatted with a GUID Partition Map as an OS X Extended and Journaled file system and plugged into the computer I'm using to make the installer USB. In the Applications folder on that computer I have the Install OS X El Capitan application downloaded from the Mac App Store. Now that I have all those conditions met, if I run the command below it should create the installer on the USB drive labeled ElCapitanInstaller.
parameter which is the path to the OS X El Capitan installer that was downloaded from the Mac App Store. The --nointeraction switch is simply telling the createinstallmedia binary to not require any interaction in the terminal when running the command. Does this explanation help and allow you to make the USB installer media?

There are two solutions to the problem, and they are both mentioned in other answers to this question and to How to get gdb to work using macports under OSX 10.11 El Capitan?, but to clear up some confusion here is my summary (as an answer since it got a bit long for a comment):
As per the answer by @user14241, disabling SIP and adding the -p option to taskgated is an option. Note that if using this option, signing the binary is not needed, and it also bypasses the dialog for authenticating as a member of the Developer Tools group (_developer).
An alternative that does not involve adding users to groups is to make the executable setgid procmod, as that also makes procmod the effective group id of any user executing the setgid binary (suggested in )
1.2 Follow the wizard to create a certificate and let's name it gdb-cert, the Identity Type is Self Signed Root, and the Certificate Type is Code Signing and select the Let me override defaults.
This doesn't necessarily address the question but if you are using Mac OS X then you can probably use lldb LLDB Homepage . It's very similar to gdb and even provides a guide to using commands that you would use on gdb.
Once you get the macports version of gdb installed you will need to disable SIP in order to make the proper edits to /System/Library/LaunchDaemons/com.apple.taskgated.plist. To disable SIP, you need to restart in recovery mode and execute the following command:
Then you will have to restart to have the changes take effect. Then you should reenable SIP. The gdb command for the macports install is actually ggdb. You will need to code sign ggdb following the instructions here:
Just spent a good few days trying to get this to work on High Sierra 10.13.1. The gdb 8.1 version from homebrew would not work no matter what I tried. Ended up installing gdb 8.0.1 via macports and this miraculously worked (after jumping through all of the other necessary hoops related to codesigning etc).
Was trying to instal el capitan on my macbook , the installation starts and after a few minutes stops and a messaging saying the os x could'nt be install on the computer, please contact the software editor to get help.
hi ,iv tried updating to el capitan and i seem to be stuck on the install screen ,every time i turn the computer off i can't seem to get many options,how do i get out of it to change the date so it will hopefully install,thanks
The only solution that worked was complicated and klutzy: 1. find a computer with installed MacOS 10.11. 2. Clone the other Mac's HD on a USB disk with CarbonCopyCloner, making sure the clone is bootable (include a working copy of CCC in the process). 3. Clone the USB disk with CCC to the Mac you're trying to upgrade. 4. erase the original user's data and put in your own info.
