Yesterday on sale Received A new version of OS X. I have no doubt that he purchased many of our readers, but I have installed so far not all. I would like to share with newcomers and switchers some tips on how to upgrade to Mountain Lion, to avoid possible problems.
For me the update on Mountain Lion - not the first. Before him were upgrades on Tiger, Leopard, Snow Leopard, Lion. The first thing you do - prepare the machine to upgrade. Always start with checking the minimum and recommended requirements.
For Mountain Lion, they are as follows:
- OS X 10.6.8 or later.
- 2 GB of memory.
- 8 GB of free disk space.
You can install Mountain Lion only relatively fresh Macs. The list is as follows:
- iMac (mid-2007 model or newer)
- MacBook (aluminum model of the end of 2008, beginning of 2009 model or newer)
- MacBook Pro (model mid / late 2007 or newer)
- MacBook Air (late 2008 model or newer)
- Mac mini (early 2009 model or newer)
- Mac Pro (early 2008 model or newer)
- Xserve (early 2009 model).
Even if your Mac meets the requirements, not the fact that all the features of ML are available. For example, for AirPlay requires iMac, Mac mini, MacBook Air, released no later than mid-2011, or MacBook Pro early 2011. Steep "trick» Power Nap is only available to owners of Macbook Air (late 2010 model or newer) and Macbook Pro with Retina-display.
Cleaning and cleaning
OS X - it's not Windows. There is no registry, and applications in the installation time is rare weep their files throughout the system. Therefore, "chistilkah" is not necessary.
However, before you upgrade to a new version of OS X is better to go through the list of applications. See in which programs no longer necessary. Better delete some free uninstaller - for example, AppCleaner.
Check if the updates come out for installed programs. This is a very important point - the update to ensure compatibility with Mountain Lion, as well as use the new features that Apple has provided developers. It may be useful website RoaringApps.
Do not be amiss to get rid of unnecessary files that take up disk space. Use programs such as OmniDiskSweeper (is free), Disk Inventory X (Free) or DaisyDisk ($ 9.99), to see which files and folders take up the most disk space. If you often download music, run the command in the iTunes File - Display Duplicates (File - Show exact duplicates). Getting rid of the multiple versions of the same song, you will increase free disk space (relevant for SSD-drives owners).
Before the upgrade should run Disk Utility (Programs - Utilities - Disk Utility) and run two checks: a disk check and verify access rights. If Disk Utility finds any errors, it is also able to fix them.
Before moving to Mountain Lion is best to install the latest available for your version of the operating system update. To do this, click the icon in the Apple menu bar and select "Software Update ...".
The last and most important step, which is almost always ignored by users: upgrade to be sure to make a backup of data. Believe me, these are not empty words.
Perhaps I shall seem paranoid, but I do three backups. First, the stick doffed active projects and keychain (Keychain), which stores passwords to websites. Then I run the Time Machine, which stores a copy of all personal data and almost all settings. In the worst case scenario you can use Time Machine, to be loaded into Lion Recovery Mode. Finally, I use Carbon Copy Cloner, which creates an exact copy of the system.
Immediately before installing I fully charge the battery Macbook Pro. Again, this may seem paranoid, but I quietly doing an upgrade, if I know that a possible power failure will not affect the installation.
That's all. Getting Started Installation:
