Cleaning of the el capitan imac

I try to wipe a computer so that I can give it.  After reading a few articles and seen some videos, all say press CMD + R while restarting.  The window of the utility they appear all say, does not appear.  I tried several times now.

It's an end 2009, running 10.11.5 imac

The only thing I can think is that my keyboard is wireless and maybe when I press the keys on the keyboard / computer does not really address it.  Don't know.  I tried making sure the keyboard is turned on before I press CMD + R, too.

Any ideas?

Thank you!!

Close all applications and shut down the system. Press command + R + power button at the same time and don't release all three keys until the ringing is heard.

Release the power button but keep on holding command, R keys until the bar load slowly until the mid.

Now, release the keys and the system will be put into recovery mode.

    It is not possible to update the version of Aperture is 3.4.5

    What can I do?

    You can only update if you have a version of the AppStore of Aperture - if your version of Aperture appears in the history of your purchases on the App Store. Update and then reinstalling.   See this tip of the user for more details:

  • What is the best method to do a clean install of El Capitan (currently using Mavericks).

    I want to do a clean install of El Capitan. I am currently using Mavs 10.9.5 and my time machine goes back to 2010. I don't want to migrate everything. I want to start cleaning up. I read a few methods, but I'm curious to know if there is some consensus as to the best method.

    Make sure that you have a Time Machine backup.

    Download El Capitan and do an install from USB.

    Start the installer from USB and install it.

  • My 2 TB TC is full and will not back up. Yet, I have only 1 TB of data on my laptop. Note that I've reformatted the laptop since the last backup with a clean installation of El Capitan.

    My 2 TB Time Capsule is full and will not save. Yet, I have only 1 TB of data on my laptop. Note that I've reformatted the laptop since the last backup with a clean installation of El Capitan.

    I bought a 2 TB external hard and have used Time Machine to back up. But I also use my time Capsule, which I save wireless.

    Any suggestions on getting my TC back up?

    One suggestion would be to copy all existing backups that are now on the Time Capsule 2 TB hard disk. Then, clear the TC and start over again with new backups.

    A more expensive option... assuming you want to keep all old backups on the TC... would be to add a new TC and start backups goes in this direction.

    Another option... If you do not need to keep all old backups now on the TC... would be to erase the TC and start over again with new backups. The benefit of doing this would be that no new material will be necessary, but the downside would be that you lose your old backup history.

  • Can I reinstall an app that I bought from the app store after a clean install of El Capitan?

    Hi all

    I did a clean install of El Capitan, which made my 2011 macbook pro currently unusable.

    A few days after installation I met problems I've ever had before. Baffled because since my drive hard worked completely fine with the Mavericks and Lion. No disk ever utility error. Computer froze a couple times the 5 years ive had the it. It has been stable.

    I explained my failed attempts to solve this problem in another thread here.

    So, if this is not relative, which seems to be caused all of this, I concluded it's a failing hard drive?

    My question is the only program of value I have logical hard disk Pro X (bought and downloaded 3 days ago) so anyway, given my problems with the hard drive I have can always reinstall logic after I got a new drive and reinstalled OSX?

    I'm on a PC at the moment and looked everywhere to find my purchase history of Logic Pro X. The only thing I can find official is my receipt by e-mail. I logged on the apple.com site with my Apple ID and it show nothing bought for the last 90 days. Active iPhone and cant find a purchase history. This suggests to me that you need to check on a mac on the App Store?

    Yes. You will need to check and it redownload via the Mac App Store with the original ID of Apple.

  • Do not click then that would start in a player flash for a clean installation of El Capitan.

    Bootable media created on a flash drive to do a clean installation of El Capitan on my MBP to Mid 2009. Once I'm booted up in the newly created disk, I can't click on anything in the public services. Chaotic strikes me disk utility, but clicking on does not. I can arrow up to my HD, but unable to select erase. To be clear, I CAN click around in disk utility when I'm booted up 'normally' in my HD. But when I restart, press the alt/option key and select the flash drive, I created for the new facility, click on in order to continue this process is not an option.

    First aid post ever. Hope that plays by the rules. Thank you very much!

    It's very strange behavier. Have you tried to clean your trackpad? Have you tried a wired mouse?

    Before you click to install flash player, the mouse was sensitive to other options?

  • How to do a clean install of El Capitan on new ssd?

    I bought a new SSD to replace the SATA drive in my Macbook Pro for mid-2010. I am running Yosemite. What I want to do, is to do a clean install of El Capitan on the SSD. I also bought a pregnant and plan on the use of the old drive as an external backup.

    I need some advice: after installing the ssd in the MBP and the old drive in the box, I intend to plug the old drive for the MBP, format the SSD drive and then use a reader flash which I did the Setup file of El Capitan to a clean of El Capitan for the SSD install and then use the Migration Wizard to migrate applications and files from the old drive.

    Is there a better way? Maybe install the SSD in the enclosure first, connect to the MBP, then shaped and do cleaning installation of El Capitan?

    All advice is appreciated.

    installing the SSD in the pregnant first, connect to the MBP, then shaped and do clean install of El Capitan?

    It's better. Some of these Macs experience problems after surgery. The new installation using the outside doing will give you confidence that it works before surgery, and no problem introduced by surgery can be separated from issues of installation and update. It will install and run in an external, just may be a little slow.

  • Clean install of El Capitan, causing all sorts of questions

    Hello

    I decided to do a clean install of El Capitan on my Macbook Pro 13 "retina end 2014 using sudo command to set up the USB bootable stick with the latest version of os x for the Mac Appstore. Installation of El Capitan appeared flawless in its execution and first start went well. Before the installation, I just formatted the disk by erasing the current drive and creating a new partition that I chose to implement the OSX on.

    Everything seems to be normal and familiar, until I try to log in iMessenger and FaceTime, which, in both cases, does not work after several attempts. Either I was told my internet connection has been lost or authentication failed. In addition to these connection problems, the overall performance of the operating system seems to be awkward and not nearly as smooth with my initial configuration to the factory system.

    I started to wonder if the current version of El Capitan available on the Appstore is flawed and broken? Someone else met weird performance / connection problems after doing a clean installation of El Capitan on their Mac recently?

    I can't use my Mac like this: someone in the support of Apple technology to address this issue now!

    Mike

    I did the same install clean, but the Apple server.  I'm having the same problem, however, there are several threads of people experiencing the same problem with the new OS X updated on El Capitan and some who use Yosemite said that they have the problem of too!  It is on the end of Apple

  • Clean install of El Capitan takes forever

    My SSD on my Mac Book Pro got some corrupted files, and I had to replace it. I am trying to do a clean install of El Capitan and it takes forever. It was 10 hours so far, and the status bar is about 75%.

    I have a new SSD, the i5 CPU, the 8 GB of RAM and 1 Gbps Internet access speed. For those who take a long time for installation and operating system is simply ridiculous. I used to be an Apple fanboy...

    The download is a function of connection. Installation depends on your hardware. Your connection may be 1 Gbit/s, but read this while you wait...

    That said, it's a very long download from Apple.

  • How to speed up my MacPro 2009 after the El Capitan updated?

    I have just the El Capitan OS installed on my MacPro machine (2009), and since I did, he managed seriously slow down. Everyone there knows a way to accelerate this return, in addition to becoming a new mac? Any help would be greatly appreciated. I already ran disk utility, cleared out the file cache, done basic diagnostic stuff. Made some power re-creation, Landau, etc. nothing helped.

    Yo mean by slow? Spinning beach ball?

    Forget the RAM Kingston and return it for a full refund, if you can.

    Spec'd correct., tested and reliable Mac RAM DO can be bought online Mac RAM sources Crucial memory, directly from the site Crucial (crucial.com) or OWC (macsales.com).

    Already mentioned several times in this post of the thread.

    Any other RAM from other sources and manufacturers (except OWC or Crucial) is questionable, at best.

  • / System/Library of the El Capitan initialization process

    Hello

    When I list all processes that are running on my mac os session, it shows me tons and tons of process/System/Library, associated with "Image Capture", "AOSKit", etc. Is this normal? I did not remember to initialize?

    I only Chrome, BetterTouch, promotion, F.lux and Terminal programs open and my consumption of memory is almost 4 GB!

    Where do I can disable these processes to automatically initialize or are they part of the execution of the El Capitan?

    Thanks in advance,

    Guilherme

    You don't have to initialize a process to make it appear. The operating system initializes dozens of processes related to the computer running and providing all the necessary services.

    Consumption memory is not directly related to how much apps that you launch. The reserve system of large chunks of memory to improve performance and have the available memory as needed. OS X will try to predict what future memory needs will be.

    Do not attempt to disable any process, if you don't know what they are for, or if they are needed. It's a sure way to crash the operating system. What you see in the activity monitor, is to help developers, technicians and others to know what works and if it's causing a problem.

    Simple rules: if it works then leave it alone; and, if you don't know what's going to happen and how to fix it, then let it be. If you want to learn more about these different processes, then try searching with Google for this information. However, if you are not a programmer you will find difficult to understand information.
