Mac el capitan problems

  1. El Capitan Update
  2. Download Os X El Capitan

If OS X El Capitan came preinstalled on your new Mac, you’ll probably never need this article until you decide to sell it. At that time, it’s a good idea to erase the disk and install a fresh copy of OS X for the next owner.

If you’re thinking about reinstalling because something has gone wrong with your Mac, know that an OS X reinstallation should be your last resort. If nothing else fixes your Mac, reinstalling OS X could well be your final option before invasive surgery (that is, trundling your Mac to a repair shop). You don’t want to reinstall OS X if something easier can correct the problem. So if you have to do a reinstallation, realize that this is more or less your last hope (this side of the dreaded screwdriver, anyway).

In this article, you discover all you need to know to install or reinstall OS X, if you should have to.Reinstalling is a hassle because although you won’t lose the contents of your Home folder, applications you’ve installed, or the stuff in your Documents folder (unless something goes horribly wrong or you have to reformat your hard drive), you might lose the settings for some System Preferences, which means you’ll have to manually reconfigure those panes after you reinstall.

And you might have to reinstall drivers for third-party hardware such as mice, keyboards, printers, tablets, and the like. Finally, you might have to reregister or reinstall some of your software.

Until 10.11 unprotects certain files in /System/Library or allows you to do it yourself, the only way without disabling SIP would be to make a different service by coping the file somewhere else, like. The problem is conflicting Python libraries, combined with System Integrity Protection (SIP) on Mac OS which protects the system Python libraries. The best solution in my opinion is to uninstall and re-install your own Python installation and keep that separate to the Python libraries provided by Mac OS which are protected by SIP.

It’s not the end of the world, but it’s almost always inconvenient. That said, reinstalling OS X almost always corrects all but the most horrifying and malignant of problems. The process in El Capitan is (compared with root-canal work, income taxes, or previous versions of OS X) relatively painless.

How to install (or reinstall) OS X

In theory, you should have to install El Capitan only once, or never if your Mac came with El Capitan preinstalled. And in a perfect world, that would be the case. But you might find occasion to install, reinstall, or use it to upgrade, such as

  • If your Mac is currently running any version of OS X except El Capitan

  • If you have a catastrophic hard-drive crash that requires you to initialize (format) or replace your boot drive

  • If you buy an external hard drive and want it to be capable of being your Mac’s startup disk (that is, a bootable disk)

  • If you replace your internal hard drive with a larger, faster, or solid state drive

  • If any essential OS X files become damaged or corrupted or are deleted or renamed

  • If you sell or give away your Mac

The following instructions do triple duty: Of course they’re what you do to install OS X for the first time on a Mac or a freshly formatted hard or solid-state disk. But they’re also what you do if something really bad happens to the copy of OS X that you boot your Mac from, or if the version of OS X on your Mac is earlier than 10.10 El Capitan. In other words, these instructions describe the process for installing, reinstalling, or upgrading OS X El Capitan.

You must have Internet access to complete this procedure.

If you’ve never had El Capitan on this Mac, the first thing to do is visit the Mac App Store, download El Capitan (it’s free), and install it. Once you’ve done that, here’s how to install, reinstall, or upgrade to El Capitan, step by step:

  1. Boot from your Recovery HD partition by restarting your Mac while holding down the Command+R keys.

    The OS X Utilities window appears.

  2. Select Reinstall OS X, and click Continue.

    The OS X El Capitan splash screen appears.

  3. Click Continue.

    A sheet informing you that your computer’s eligibility needs to be verified by Apple appears.

  4. Click Continue to begin the process of installing or reinstalling OS X.

    If you’re not connected to the Internet, you’ll be asked to choose a Wi-Fi network from the AirPort menu in the top-right corner.

    The El Capitan software license agreement screen appears.

  5. Read the license agreement and click Agree.

    A sheet drops down, asking whether you agree to the terms of the license agreement.

  6. Click Agree again.

    Yes, you did just click Agree; this time you’re being asked to confirm that you indeed clicked the Agree button. If you don’t click Agree, you can’t go any farther, so I advise you to click Agree now.

  7. Choose the disk on which you want to reinstall OS X by clicking its icon once in the pane where you select a disk.

    If only one suitable disk is available, you won’t have to choose; it will be selected for you automatically.

  8. Click the Install button.

    A sheet asks for your Apple ID and password.

  9. Type your Apple ID and password in the appropriate fields, and click Sign In.

    Your El Capitan installation (or reinstallation) begins. The operating system takes 30 to 60 minutes to install, so now might be a good time to take a coffee break. When the install is finished, your Mac restarts itself.

If you were reinstalling El Capitan on the hard disk that it was originally installed on, or upgrading from Mavericks, you’re done now. Your Mac will reboot, and in a few moments you can begin using your new, freshly installed (and ideally trouble-free) copy of OS X El Capitan.

If, on the other hand, you’re installing El Capitan on a hard disk for the first time, you still have one last step to complete. After your Mac reboots, the Setup Assistant window appears.

Getting set up with the Setup Assistant

Assuming that your installation process goes well and your Mac restarts itself, the next thing you should see (and hear) is a short, colorful movie that ends by transforming into the first Setup Assistant screen (Apple Assistants such as this are like wizards in Windows, only smarter), fetchingly named Welcome.

To tiptoe through the Setup Assistant, follow these steps:

El Capitan Update

  1. When the Welcome screen appears, choose your country from the list by clicking it once, and then click the Continue button.

    If your country doesn’t appear in the list, select the Show All check box, which causes a bunch of additional countries to appear.

    After you click Continue, the Select Your Keyboard screen appears.

  2. Choose a keyboard layout from the list by clicking it once, and then click Continue.

    If you want to use a U.S. keyboard setup, click the U.S. listing. If you prefer a different country’s keyboard layout, select the Show All check box; a bunch of additional countries’ keyboards (as well as a pair of Dvorak keyboard layouts) appear in the list. Choose the one you prefer by clicking it — and then click Continue.

    The Select Your Wi-Fi Network screen appears.

  3. Click the name of the wireless network you use to connect to the Internet, type its password, and then click Continue.

    If you don’t see the network you want to use, click Rescan.

    If you don’t use a wireless network, click Other Network Setup, and then choose one of the available options, or choose My Computer Does Not Connect to the Internet. Click Continue.

    The Migration Assistant (also known as the Transfer Information to This Mac) screen appears.

  4. Do one of the following:

    • Choose to transfer data, and then click Continue.

      If this is a brand-new Mac or you’re installing OS X El Capitan on a Mac and have another Mac or Time Machine backup disk nearby, you can transfer all of your important files and settings by following the onscreen instructions and connecting the new and old Macs via FireWire or Ethernet cable.

      Transferring data can take hours — that’s the bad news.

      The good news is that once the data transfer finishes, you’re finished, too. In other words, you can ignore the steps that follow (which are only for brand new installations with no data to transfer).

      Goodbye and good luck.

    • Choose not to transfer data, and then click Continue.

      The Enable Location Services screen appears. Location Services allows apps such as Maps and services such as Spotlight Suggestions to gather and use data including your approximate location.

  5. Select (or don’t select) the Enable Location Services on this Mac check box, and then click Continue.

    The Sign In with Your Apple ID screen appears.

  6. Do one of the following:

    • If you want to use your Apple ID with this Mac, type your ID (such as tcook@me.com) and password in the appropriate fields, and then click Continue.

    • If you don’t have an Apple ID or prefer not to use one with this Mac, click Don’t Sign In, and then click Continue.

      To learn more about getting an Apple ID, click the blue Learn More link. In a nutshell, an Apple ID lets you make one-click purchases at the iTunes Store, iPhoto, or the Apple Store, and includes free iCloud membership.

    The Terms and Conditions screen appears.

  7. Read the Terms and Conditions and click Agree.

    A sheet drops down to confirm your agreement.

  8. Click Agree again.

    The Create a Computer Account screen appears.

  9. Do one of the following:

    • If you provided your Apple ID (in Step 6), select the Use My iCloud Account to Log In check box. Then fill in the Account Name (sometimes called Short Name).

    • Fill in the Full Name, Account Name (sometimes called Short Name), Password, Verify Password, and Hint fields.

    This first account that you create will automatically have administrator privileges for this Mac. You can’t easily delete or change the name you choose for this account, so think it through.

    You can’t click the Continue button until you’ve filled in the first two fields. Because a password is optional, you can choose to leave both password fields blank if you like. If you do, your Mac warns you that without a password, your Mac won’t be secure. If that’s okay, click OK. If you change your mind and want to have a password, click Cancel.

  10. If you want a different picture, click the little picture to the right of your name (labeled “edit”) and do one of the following:

    • To take a picture of yourself with your Mac’s built-in camera, click the Take Photo Snapshot button. Then click Continue.

      When the picture appears, you can change its size by using the slider control directly below the image and move it around in the frame by clicking your face and dragging. If you’re not happy with this snapshot, click Retake a Video Snapshot.

    • To select a picture from the Picture library, click the picture you want to represent you — the butterfly, dog, parrot, flower, or whatever — and then click Continue.

  11. Click Continue to exit the Create a Computer Account screen. If you didn’t provide an Apple ID, skip to Step 13.

    If you provided your Apple ID in Step 6, the Set Up iCloud Keychain screen appears.

  12. Do one of the following:

    • Click Set Up iCloud Keychain. When the screen requesting your passcode appears, type your four-digit passcode, and click Continue.

      If you’ve forgotten your passcode or don’t have one, click Forgot Code to Reset iCloud Keychain.

      A verification code is sent to your iPhone or other Apple device.

    • Click Set Up Later.

      If you choose this option, skip to Step 14.

  13. Type the code in the verification field and then click Continue.

  14. Wait a few minutes while your user account is created and El Capitan is configured for you.

    The OS X Finder’s Desktop appears.

And that’s all there is to it. You’re done.

You need to know whether your Mac system will run the new Mac OS X El Capitan and one of the things you need to check is whether the latest version of Mac OS is supported by your Mac hardware. The new Mac OS X El Capitan will be released by the end of June of 2015, and the hardware system requirement can be enormous. Your hardware should be able to run the latest Mac OS X El Capitan if it has OS X Yosemite or OS X Mavericks: these two are the basic hardware requirements you should consider. However, if your system doesn’t meet these basic requirements, you don’t have to get out of your way and purchase a new hardware, for most of the Mac OS released in the past 5 years will be supported.

Part 1. Supported Mac Models and Hardware for Mac OS X El Capitan

As far as Hardware requirements are concerned, the new Mac OS X El Capitan will support the following hardware:

  • ● iMac ( from 2007 upwards);
  • ● The 13 inch Aluminum 2008 edition MacBook, or 2009 edition and older;
  • ● The 13 inch 2009 MacBook Pro;
  • ● The 15-inch or 17-inch , 2007 MacBook Pro or newer versions;
  • ● The 2008 MacBook Air or newer version;
  • ● The 2009 Mac Mini or newer version;
  • ● The 2009 early edition Xserve.

Some of the Mac systems that do not meet up with the minimum hardware requirements for Mac OS X El Capitan include: iMac 4.1 to 6.1, MacBook 1.1 to 4.1, MacBook Pro 1.1 to 2.1, MacBook Air 1.1, Mac Mini 1.1 to 2.1, Mac Pro 1.1 to 2.1, and Xserve 1.1 to 2.1.

Part 2. What Are the System Requirements for Updating?

One of the most important system requirements for the installation of Mac OS X El Capitan is that your Mac system must possess 64-Bit CPU, and this is a typical component of Intel Core 2 Duo or a newer version of processor. Beyond the CPU processor requirement, most other requirements are quite easier to meet up with. You need to have at least 10GB of dick space in order to install the final version of Mac OS X El Capitan. If you are unsure about your hardware system, you can have a quick check by simply going to the Apple menu, then click on 'About This Mac', and choose 'Overview', and then look out for the name of your Mac device and the year manufactured.

The optimal requirements for a better performance are quite different. However, system speed requirements are general for all Mac devices, and the newer the Mac device, the faster the software and apps will run. The more the RAM memory for instance, the faster your Mac OS X El Capitan software runs on your system, in addition, a faster SSD Disk drive will boost the performance of the software on your Mac.

Part 3. The Optimal Requirements for Mac OS X El Capitan

  • RAM - The minimum RAM requirement for optimal performance and installation of Mac OS X El Capitan is 2GB. Though this could still be slow, a 4GB RAM size is preferred, and even larger RAM will make the Mac OS X El Capitan perform at faster rates.
  • The Drive Space - Your Mac device will require a minimum of 8GB of drive space to function at its optimal. The minimum 8GB does not provide the ideal amount of free space to effectively run Mac OS X El Capitan for a long time, but the space will help you complete its installation. If you are trying out Mac OS X El Capitan on a virtual machine, or on a partition, you may need as much as 16GB minimum for the installation and running of the software- this space will accommodate the applications installed. However, you will need up to 80GB of space if you are installing the software on a real world PC environment.

Part 4. Why We Should Update to Mac OS X El Capitan?

Mac OS X El Capitan is not just an upgrade, it comes with some new and exciting features that make it more powerful, usable and more flexible than previous Mac OS. The main reasons why you should update to Mac OS X El Capitan include:

Performance Improvement - The new Mac OS X El Capitan opens PDF documents 4 times faster than the fastest Mac OS, displays your emails 2 times faster, provides 2 times faster app switching time and up to 1.5 times faster Apps launching. Generally the performance of Mac OS X El Capitan is far greater than the Mac Yosemite. Generally your system becomes twice faster and more responsive with Mac OS X El Capitan.

Spotlight Enhancements - Another reason why you should update to Mac OS is that the new Spotlight feature allows you to resize and move the window around the desktop screen. Likewise you can now write queries and codes in natural language, and you can track down your mails and documents easily through the search. The new Spotlight provides new transit directions for your videos, Maps, stocks and much other vital information.

New Split View & Mission Control - With the new Mac OS X El Capitan, you can now split your screen in equal halves and run two apps at the same time. The new Split View mode means you don’t have to split the screen manually and this new system helps you save time while browsing through contents and writing on the other screen. Mission control provides an easy switch between all opened apps thus they do not overlap on your desktop.

Library

In-built App Enhancements - With the new Mac OS X El Capitan, you can edit your pictures and add some details. The new Safari can also help you mute background noises from apps, while the Maps in the Mac OS X El Capitan helps you plan your trips even much easier by providing you with details of public transportation, subway routes and many more.
