Install Latest Mac Os On Old Macbook Pro

Not all Macs can be upgraded to the latest OS version. For instance, old Macs powered by PowerPC CPUs cannot run OS intended for Intel-based computers. Also, some versions have hardware limitations. For instance, Mojave cannot be installed on MacBook Pro earlier than Mid 2012 model. Check below to know exactly what version of OS your Mac can run. With macOS Monterey, Apple is dropping support for 2013 and 2014 MacBook Pro, MacBook Air, and iMac models, as well as the 2015 MacBook. If you have one of these newly unsupported models, or if you have an even older Mac, you’re likely wondering how to install macOS Monterey on it using Open Core Legacy Patcher. The Mojave 10.14.1 update does NOT install properly on unsupported machines, and could result in an unbootable OS. If you want to install the 10.14.1 update (and are not currently running 10.14.1), perform the following steps:. Download the latest version of Mojave Patcher. Download the installer using the Tools menu of Mojave Patcher.

  • Supported version: 0.6.7

While you don't need a fresh install of macOS to use OpenCore, some users prefer having a fresh slate with their boot manager upgrades.

In the old guide, you needed to install a custom audio kext (your Mac's equivalent to a driver); the setup has been slightly tweaked in this new method, so all you should actually need to do is. Installing Linux Mint on your PC or Mac opens up a whole range of new open-source software and capabilities. It involves some initial preparation, but in the end, you'll find it worth the investment. It involves some initial preparation, but in the end, you'll find it worth the investment. A window appears that says 'Installer is trying to install new software. Type your password to allow this.' Enter the Administrator login and password and click Install Software. The software is installed and a confirmation window appears.

To start we'll want to grab ourselves a copy of macOS. You can skip this and head to formatting the USB if you're just making a bootable OpenCore stick and not an installer. For everyone else, you can either download macOS from the App Store or with Munki's script.

# Downloading macOS: Modern OS

  • This method allows you to download macOS 10.13 and newer, for 10.12 and older see Downloading macOS: Legacy OS

From a macOS machine that meets the requirements of the OS version you want to install, go directly to the App Store and download the desired OS release and continue to Setting up the installer.

For machines that need a specific OS release or can't download from the App Store, you can use the Munki's InstallInstallMacOS utility.

In order to run it, just copy and paste the below command in a terminal window:

As you can see, we get a nice list of macOS installers. If you need a particular versions of macOS, you can select it by typing the number next to it. For this example we'll choose 10:

  • macOS 11, Big Sur Note: As this OS is quite new, there's still some issues with certain systems to resolve. For more information, see here: OpenCore and macOS 11: Big Sur
    • For first time users, we recommend macOS 10.15, Catalina
  • Nvidia GPU Note: Reminder to verify whether your hardware support newer OSes, see Hardware Limitations

This is going to take a while as we're downloading the entire 8GB+ macOS installer, so it's highly recommended to read the rest of the guide while you wait.

Install New Os On Mac With Replaced Hard Drive

Once finished, you'll find in your ~/macOS-Installer/ folder a DMG containing the macOS Installer, called Install_macOS_11.1-20C69.dmg for example. Mount it and you'll find the installer application.

  • Note: We recommend to move the Install macOS.app into the /Applications folder, as we'll be executing commands from there.
  • Note 2: Running Cmd+Shift+G in Finder will allow you to easily jump to ~/macOS-installer

From here, jump to Setting up the installer to finish your work.

# Downloading macOS: Legacy OS

  • This method allows you to download much older versions of OS X, currently supporting all Intel versions of OS X(10.4 to current)

    • Legacy macOS: Offline method
      • 10.10-10.12 Supported
    • Legacy macOS: Online method(10.7-10.15 Supported)
      • 10.7-11 Supported
    • Legacy macOS: Disk Images
      • 10.4-10.6 Supported

# Setting up the installer

Now we'll be formatting the USB to prep for both the macOS installer and OpenCore. We'll want to use macOS Extended (HFS+) with a GUID partition map. This will create two partitions: the main MyVolume and a second called EFI which is used as a boot partition where your firmware will check for boot files.

  • Note: By default, Disk Utility only shows partitions – press Cmd/Win+2 to show all devices (alternatively you can press the View button)
  • Note 2: Users following 'Legacy macOS: Online method' section can skip to Setting up OpenCore's EFI environment

Next run the createinstallmedia command provided by Apple(opens new window). Note that the command is made for USB's formatted with the name MyVolume:

This will take some time so you may want to grab a coffee or continue reading the guide (to be fair you really shouldn't be following this guide step by step without reading the whole thing first).

You can also replace the createinstallmedia path with that of where your installer's located (same idea with the drive name).

Legacy createinstallmedia Commands

Pulled from Apple's own site: How to create a bootable installer for macOS(opens new window)

# Legacy Setup

For systems not supporting UEFI boot, see below:

Setting up Legacy Boot

To start, you need the following:

  • BootInstall_IA32.tool or BootInstall_X64.tool
    • This can be found in OpenCorePkg under /Utilties/LegacyBoot/
  • Install USB(Created above)

Within your OpenCore build folder, navigate to Utilities/LegacyBoot. Here you'll find a file called BootInstall_ARCH.tool. What this does is install DuetPkg to your desired drive.

Now run this tool in terminal with sudo(This tool will likely fail otherwise):

This will give you a list of available disks, choose yours and you will be prompted to write a new MBR. Choose yes[y] and you'll be finished.

This will provide you with an EFI partition with either a bootia32 or bootx64 file

# Setting up OpenCore's EFI environment

Setting up OpenCore's EFI environment is simple – all you need to do is mount our EFI system partition. This is automatically made when we format with GUID but is unmounted by default, this is where our friend MountEFI(opens new window) comes in:

You'll notice that once we open the EFI partition, it's empty. This is where the fun begins.

# Now with all of this done, head to Setting up the EFI to finish up your work

This page describes how to install and uninstall JDK 8 for OS X computers.

How To Install Macos On New Ssd

This page has these topics:

See 'JDK 8 and JRE 8 Installation Start Here' for general information about installing JDK 8 and JRE 8.

See 'OS X Platform Install FAQ' for general information about installing JDK 8 on OS X.

System Requirements

Observe the following requirements:

How To Install Os On Old Macbook

  • Any Intel-based computer running OS X 10.8 (Mountain Lion) or later.

  • Administrator privileges.

Note that installing the JDK on OS X is performed on a system wide basis, for all users, and administrator privileges are required. You cannot install Java for a single user.

Install Latest Mac Os On Old Macbook Pro

Install New Os On Macbook Pro

Installing the JDK also installs the JRE. The one exception is that the system will not replace the current JRE with a lower version. To install a lower version of the JRE, first uninstall the current version as described in 'Uninstalling the JRE'.

JDK Installation Instructions

When you install the Java Development Kit (JDK), the associated Java Runtime Environment (JRE) is installed at the same time. The JavaFX SDK and Runtime are also installed and integrated into the standard JDK directory structure.

Depending on your processor, the downloaded file has one of the following names:

Install
  • jdk-8uversion-macosx-amd64.dmg

  • jdk-8uversion-macosx-x64.dmg

Where version is 6 or later.

  1. Download the file.

    Before the file can be downloaded, you must accept the license agreement.

  2. From either the Downloads window of the browser, or from the file browser, double click the .dmg file to launch it.

    A Finder window appears containing an icon of an open box and the name of the .pkg file.

  3. Double click the package icon to launch the Install app.

    The Install app displays the Introduction window.


  4. Enter the Administrator login and password and click Install Software.

    The software is installed and a confirmation window appears.

  5. Refer to http://www.oracle.com/technetwork/java/javase/downloads/jdk-for-mac-readme-1564562.html for more information about the installation.

  6. After the software is installed, delete the .dmg file if you want to save disk space.

  7. Determining the Default Version of the JDK

    If you have not yet installed Apple's Java OS X 2012-006 update, then you are still using a version of Apple Java 6 that includes the plug-in and the Java Preferences app. See 'Note for Users of OS X that Include Apple Java 6 Plug-in'.

    There can be multiple JDKs installed on a system, as many as you wish.

    When launching a Java application through the command line, the system uses the default JDK. It is possible for the version of the JRE to be different than the version of the JDK.

    You can determine which version of the JDK is the default by typing java -version in a Terminal window. If the installed version is 8u6, you will see a string that includes the text 1.8.0_06. For example:

    To run a different version of Java, either specify the full path, or use the java_home tool:

    For more information, see the java_home(1) man page.

    Uninstalling the JDK

    To uninstall the JDK, you must have Administrator privileges and execute the remove command either as root or by using the sudo(8) tool.

    For example, to uninstall 8u6:

    Do not attempt to uninstall Java by removing the Java tools from /usr/bin. This directory is part of the system software and any changes will be reset by Apple the next time you perform an update of the OS.
