Features and benefits of Mac OS X 10.8




Mac OS X 10.8, also known as Mountain Lion, was released in July 2012 as the ninth major version of macOS. It introduced many new features and improvements to the operating system, such as stability, security, performance, and compatibility. Here are some of the main features and benefits of Mac OS X 10.8:


Stable operating system




Mac OS X 10.8 improved the stability of the operating system and fixed some bugs and issues from previous versions. For example, it resolved a problem that caused the system to freeze when using Pinyin input, a problem that prevented Safari from launching when using a Proxy Automatic Configuration (PAC) file, and a problem that caused screen flickering when using Adobe Photoshop. It also improved the reliability of Microsoft Exchange connections and the compatibility of USB devices.


Security enhancements




Mac OS X 10.8 enhanced the security of the operating system and protected users from malware and phishing attacks. It introduced a new feature called Gatekeeper, which allowed users to control which applications can be installed and run on their Macs. Users could choose to allow applications from the Mac App Store, from identified developers, or from anywhere. It also added support for FileVault 2 encryption for external drives, iCloud Keychain for storing passwords and credit card information, and Safari Password Generator for creating strong passwords.


Increased performance of MacBook




Mac OS X 10.8 increased the performance of MacBook models by optimizing battery life, Wi-Fi speed, and graphics processing. It implemented a new feature called Power Nap, which allowed MacBook Air and MacBook Pro models to update email, contacts, calendars, reminders, notes, Photo Stream, Find My Mac, and iCloud documents while sleeping. It also improved the Wi-Fi performance when connected to 5 GHz networks, and enhanced the graphics performance for NVIDIA GeForce graphics processors.



Sending huge data over the internet




Mac OS X 10.8 enabled users to send huge data over the internet using AirDrop, iCloud, and Messages. AirDrop allowed users to share files wirelessly with other Macs nearby, without requiring a Wi-Fi network or an internet connection. iCloud allowed users to store and sync their documents, photos, music, contacts, calendars, and more across their devices, and access them from any web browser. Messages allowed users to send unlimited text messages, photos, videos, contacts, and documents to anyone using an iPhone, iPad, iPod touch, or another Mac.


Fixes for screen saver issues and smart card




Mac OS X 10.8 fixed some screen saver issues and added support for smart card authentication. It resolved a problem that caused the screen saver to start automatically even if it was disabled in System Preferences, and a problem that prevented the screen saver from starting after waking from sleep. It also added the ability to use a smart card to log into OS X, unlock the screen saver, and authenticate to some applications.


Compatibility and requirements of Mac OS X 10.8




Before you download and install Mac OS X 10.8 iso file on your Mac, you need to make sure that your Mac is compatible with it and meets the minimum requirements. Here are the compatibility and requirements of Mac OS X 10.8:



Supported Mac models




Not all Mac models can run Mac OS X 10.8. According to Apple, the following Mac models are supported:


  • iMac (Mid 2007 or newer)

  • MacBook Air (Late 2008 or newer)



  • Mac mini (Early 2009 or newer)

To install and run Mac OS X 10.8, you need to have at least 2 GB of memory and 8 GB of available storage space on your Mac. You can check your memory and storage by clicking the Apple menu, choosing About This Mac, and clicking More Info. If you need to upgrade your memory or storage, you can consult the Apple Support website for instructions.


Internet service provider requirements




To use some features of Mac OS X 10.8, such as iCloud, FaceTime, and Apple Pay, you need to have an internet service provider that offers a broadband connection.

Installation guide for Mac OS X 10.8 iso download free




Now that you have checked the compatibility and requirements of Mac OS X 10.8, you are ready to download and install it on your Mac. However, you cannot simply download the iso file and double-click it to install it. You need to create a bootable installer on an external drive or secondary volume using the iso file, and then use it to install Mac OS X 10.8 on your Mac. Here are the steps to do so:


Downloading the iso file




The first step is to download the iso file from a trusted source. You can find many websites that offer Mac OS X 10.8 iso download free, but not all of them are reliable and safe. Some of them may contain malware or corrupted files that can harm your Mac. Therefore, you should always verify the integrity of the iso file before using it. One way to do that is to compare the checksum of the iso file with the original checksum provided by Apple. A checksum is a unique code that identifies a file and can detect any changes or errors in it. You can use a tool like MD5 or SHA1 to generate and compare checksums.


For example, according to Apple, the original checksum of the Mac OS X 10.8 iso file is 4E7B25EEC0AD4D7890F512D1DF1C7F09 (MD5) or 6D2F354F7BCD9BFC9E8F7FEB4E1A5AEDBFE631F1 (SHA1). You can download the iso file from a website like [Mac OS X ISO], which claims to have the same checksum as Apple. After downloading the iso file, you can use Terminal to generate and compare the checksums using the following commands:


md5 /path/to/iso/file


sha1 /path/to/iso/file


If the checksums match, then you can proceed to the next step. If they don't, then you should delete the iso file and download it from another source.


Creating a bootable installer




The next step is to create a bootable installer on an external drive or secondary volume using the iso file. A bootable installer is a device that contains a copy of the operating system and can be used to start up your Mac and install it. You can use any external drive or secondary volume that has at least 12 GB of available space and is formatted as Mac OS Extended (Journaled). You can check the format of your drive or volume by using Disk Utility.


To create a bootable installer, you need to use Terminal again and enter a command that will erase your drive or volume and copy the iso file to it. The command will look something like this:


sudo /Applications/Install\ macOS\ Mountain\ Lion.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install\ macOS\ Mountain\ Lion.app --nointeraction


In this command, you need to replace MyVolume with the name of your drive or volume, and /Applications/Install\ macOS\ Mountain\ Lion.app with the path to your iso file. You also need to enter your administrator password when prompted.


This command will take some time to complete, so be patient and do not interrupt it. When it is done, you will see a message like this:


Copy complete. Making disk bootable... Copying boot files... Copy complete. Done.


This means that your bootable installer is ready and you can move on to the final step.



Installing Mac OS X 10.8 from the bootable installer




The final step is to install Mac OS X 10.8 on your Mac from the bootable installer. To do this, you need to restart your Mac from the bootable installer and follow the on-screen prompts to install it. Here are the steps to do this:


  • Connect your bootable installer to your Mac.



  • Restart your Mac and hold down the Option key as it starts up.



  • Select your bootable installer from the list of startup disks and click Continue.



  • Choose your language and click Continue.



  • Select Install macOS and click Continue.



  • Agree to the terms and conditions and click Agree.



  • Select the disk where you want to install Mac OS X 10.8 and click Install.



  • Wait for the installation to complete and restart your Mac.



Congratulations, you have successfully installed Mac OS X 10.8 on your Mac using a bootable installer. You can now enjoy the features and benefits of this operating system.
