If I have a SSD and am using CCC regularly, do I need to create a bootable USB drive with the Recovery Partition on it like in years past?
If you've created a bootable clone using CCC (which also has the ability to "clone over" the recovery partition to your backup), you have a choice:
a. boot from the recovery partition on the cloned backup, or
b. boot from the cloned backup itself.
Actually, option b would always ALWAYS be my preferred method.
Questions:
- have you TRIED creating a bootable backup yet?
- if so, have you TRIED booting from it?
Since Macs with SSDs no longer have a Recovery Partition, your CCC clone should suffice for being able to troubleshoot.
I suggest always having some sort of utility for when things go awry. They have the Internet Recovery utility built into all new Macs, but I have a spare USB drive loaded up with the current OS release as a just-in-case. To make one, all you have to do is download the OS installer from the App Store and use the free DiskMaker X software to create the Bootable USB on any 8GB drive.

The recovery partition provides you with a way to boot and attempt a modicum of repairs if for some reason you can't boot from the "main" partition.
I never use it -- well, almost never.
However, with the coming of El Capitan and Sierra, there MUST be a recovery partition available if one needs to turn off SIP (System Integrity Protection). I believe there are a few other things it's required for. So, yes, you DO want a recovery partition around.
If you create and maintain a BOOTABLE CLONED BACKUP using CarbonCopyCloner or SuperDuper, you will almost never NEED the recovery partition.
Because you can boot from your cloned backup instead, right "into the finder", and then have ALL your tools available.
Original Question:Back to my original questions...
No, you do not absolutely "need" to, if you do not want to take the time and effort to make a USB installer. The Recovery partition will be available on the cloned SSD.If I have a SSD and am using CCC regularly, do I need to create a bootable USB drive with the Recovery Partition on it like in years past?
Neither are particularly important questions, as i keep a separate copy of (bootable) OS X, whatever I happen to be running at the moment.
Apple information on what the Recovery Partition does (a result from search for "Recovery Partition" at Apple):
https://support.apple.com/en-us/HT201314
Note: The link information is geared for macOS, but it is the same for El Capitan (if your Recovery Partition is from El Capitan it will download & install El Capitan).
In the old days, you had a CD with the os on it, so if your HDD ever died, or you had viruses galore - think PCa - then you just popped in the CD, reinstalled your os, and you had a like new machine.
That option no longer exists, and what I am unsure of is what the purpose of the hidden Recovery Partition is.
From what I can tell, it allows you to boot up your Mac when you have no OS, and then apparently there is some program in it that allows it to connect to Apple's servers and download a new version of the OS which came with your Mac.
Is that correct?
If so, it seems like it is crucial to have a copy of the Recovery Partition on an external and separate media device, should your SSD or HDD in your Mac become unusable, right?
When I did this 4 years ago, and before I had CCC, a friend told me to buy an 8GB USB drive and do whatever he told me so I could use that to rebuild my machine in case of disaster. I dom't know what we did to my USB, but I emember he stressed that I should create one the minute I turned on my new Mac.
Fast forward 4 years, and I have it in my mind that I need another one of these bootable USB drives, but I don't know what should be on it, or what it is supposed to do.
It would seem to me that if I create a bootable clone of my new Mac - including the Recover Partition - and keep that drive in a safe place, that is all I would need should my new Mac become corrupt. Because I could either roll back to the latest clone, OR I could use the Recovery Partition on the backup drive to fix whatever is wrong with my new Mac.
Maybe I should create a bootable USB drive like I did 4 years ago?
If the latter is true, then I could use some help understanding how to create such a bootable USB drive and understanding what it does.
For example, does the bootable USB drive...
- Contain El Capitan?
- Contain some program that just lets me download El Capitan?
- Or does it hold my entire HDD?
Yes. Theres is a hidden 650MB Recovery HD volume on your drive. If you boot holding command-r it will boot to that recovery utility. From there you can use Disk Utility to erase or check the rest of the drive if you want or you can reinstall the OS. If you click to reinstall the OS, you will be asked to enter the AppleID you used to "purchase" El Capitan (in your case). Then the 6GB or so OS will download from Apple's servers and install on your drive. If the recovery volume is from El Capitan this will get your El Capitan... if it is Yosemite you will get Yosemite and so on.
Kinda... yes. It is less an issue with newer models like yours because you always have Internet recovery to fall back on. In your case, let's say you have a total drive failure. You could pop in a new drive and command-option-r to Internet recovery. This is a firmware based process that downloads that 650MB recovery utility onto a RAM disk and then allows you to format the new drive and reinstall the OS by downloading it over the Internet. Internet recovery will get you the OS version that came from the factory, in your case Mountain Lion. Then once you are up and running on Mountain Lion, you could update back to El Capitan or Sierra.
This is more an issue in older Macs without Internet recovery. If you don't have an original installer CD or USB key with the OS, you would be in a pickle with a total drive failure if you had no backup or method to get the OS back on there.
Your thinking here is correct. If you have a good backup and clone, there is little reason to fuss around with the USB key. Particularly with a newer machine like yours where you can always fall back on Internet recovery.
If you download the El Capitan installer right now from the App Store, then follow this to make a USB key installer, it will have the recovery utility and the entire OS on the USB key and iuf you used that to install to a new, blank drive, nothing would need to be downloaded at that time. All the installer contains is the OS... not any data or anything else from your HDD.
Like I said, IMO with a newer Mac there is not much need to keep these USB installers around, particularly if you have a clone available like you do.
So the Recovery Partition does not hold the actual operating system (e.g. El Capitan), but just a utility that takes to Apple's servers to download the entire OS, right?
What version of OS did Internet Recovery become an option?
Again, so without the program that downloads the OS from Apple - which is on the Recovery Partition - then you would have no means to download a replacement OS, right?
That is to say, you can't just connect your broken Mac to Apple's website and download an OS, you need the program on the Recovery Partition to help you do that, right?
Can I use CCC to make a bootable USB drive with the Recovery Partition on it?
Even though you agreed with me here, if I ever wanted to install the base El Capitan OS on a separate SSD or HDD to play around with things, then it would be better to have a clone of my virgin machine before I started adding data.
For instance, I would like to play around sometime and learn more about hardening my mac and playing with command-line, and it would be nice to have a copy of my new mac - without any data on it - so I could break things and not worry about impacting my main machine.
So is it possible to do that using CCC?
Okay, this is where I was getting really confused before...
Questions:
1.) How do i download the El Capitan installer?
I broke down and created an Apple ID when I bought my new rMBP, but I have never used it to buy anything other than on Apple.com. I have no clue of how to use iTunes or download music or apps aor the installer, and when I tried last night I got totally confused and lost!!
2.) I thought the "Installer" was just the same program located on the Recovery Partition that talks to Apple's servers and allows you to download whatever OS?
You make it sound like the "Installer" is actually a full copy of OS-X??
3.) How hard would it be to create a USB installer? (My friend did it for me 4 years ago.)
That is good to know, but if it isn't too hard, and I can figure out how to unlock my old USB drives - I think I encrypted them - I would like to try and make a copy of my new MBP before I add anything to it. Then if I want to install another HDD as a "test machine" I will have it, and I won't have to worry about putting any data on it.
Creating a bootable USB installer (which boots to mostly the same "look" as booting to either Recovery system, or Internet Recovery) is easy-peasy. All you need is to download the version of OS X (macOS) that you want, then use a couple of simple terminal commands to do the creation. Easy to find, just search.
(I would suggest that you get a brand-new USB flash drive, that you can dedicate to an installer. 8GB sticks are sometimes less than $3 - I just bought a 4-pack for under $12 - and are the ideal size for an OS X installer.)
Is there a way to have a complete copy of a newly installed OS?
Texas Toast, WHY do you always make things so difficult?
Why not do it the easy way, like this:
1. Initialize your [to-be] backup drive.
2. Use CCC to clone your internal drive to the backup
3. CCC will ask if you wish to clone over the recovery partition as well.
4. Say yes.
5. Let CCC do its thing.
Just do this, and you will have BOTH a clone of the internal drive AND of the recovery partition as well.
You'll now have FOUR WAYS to boot the Mac:
1. internal main drive
2. internal recovery partition
3. external clone of main drive
4. external recovery partition.
There's NOTHING involved or complicated to doing this.
It's as simple as clicking a few buttons in CCC.
WHY make it so hard?
You mean not just the installer, but a working version of the full OS?
Sure, just command-r boot to recovery and from there erase the internal drive with Disk Utility then quit Disk Utility and click reinstall OS. When that gets done it will restart and begin the system setup process. When that happens hold down the power button to force shutdown. Now command-r back to recovery. Now start Disk Utility and go to the restore tab. Then "restore" Macintosh HD to a formatted external drive. That will give you a clone of a fresh OS setup with nothing else on there.
