How to access and use the Internet Recovery mode on Mac computers?
Apple computers are well-known as stable devices with good performance and hardware specifications. The Mac operating system also includes various self-diagnosis and repair tools. Bear in mind, however, that these features might be susceptible to failure. When built-in tools or software-based solutions do not work, the last and most efficient solution is to reinstall the operating system. All modern Mac computers contain two separate methods to reinstall the operating system (by 'reinstall', we mean installation of a fresh OS X version). You can choose to install the operating system from a startup disk or via Internet Recovery.
In this article, we describe the second method: Internet Recovery to install the operating system version that came with the version of your computer. If your computer was released with OS X Mavericks, using Internet Recovery will install this particular version, while reinstallation from the recovery partition will result in a fresh version of the current operating system. Therefore, if you perform the reinstallation process via the Recovery utility, you will receive the same operating system version that existed prior to reinstallation. The Internet Recovery method is useful if you wish to downgrade the operating system. A big advantage of this method is the ability to bring back the computer to full functionality when software is corrupted. Note, however, that stable internet access is required to perform the reinstallation process via Internet Recovery. An unstable Internet connection can lead to the process crashing and no access to the computer. Therefore, you are advised to use an Ethernet network, rather than Wi-Fi. In this article, we walk through the entire Internet Recovery method.
I just purchased a NIB Colt SAA with a serial number SXXXXXA stamped in the bottom of the frame just ahead of the trigger guard assembly. I went to the Colt web page to try to find the year of manufacture and it comes back as unable to find. Just out of curiosity, I instead typed XXXXXSA and the web site found the year it was built. Enter the serial number, without spaces or dashes, to search the database. If multiple models appear for your serial number simply match the date with the appropriate model, as certain vintage firearms can share serial numbers between different models. Colt SAA serial numbers went to 99999SA in 1978. Adobe cc 2017 master collection mac download torrent. Then they were switched to SA1001. In 1993 number SA99999 was reached, then Colt split the SA to S2001A. Why they skipped about a thousand numbers when going to the SA prefix and 2,000 when splitting the SA remains a mystery. Colt saa 3rd generation serial numbers. Third Generation serial numbers started over again at 80,000SA, leaving a gap of 5,000-plus after discontinuance of the 2nd Generation. My first 3rd Generation SAA had a number about 500 into that 80,000SA range. Happily not all 3rd Generation SAAs were as poorly put together as mine.

Finally, when you are ready to reinstall the operating system, click the Apple logo in the menu bar at top of the screen and select Restart or Shut Down. Once the system starts booting and you hear the startup chime, hold down the combination of Command, Option (Alt), and R.
Keep holding these keys until the animated globe appears with the message below stating 'Starting Internet Recovery' and 'This may take a while'. Note: If you are using a Mac laptop, use the built-in keyboard to access Internet Recovery Mode, since keystrokes might not register properly on external keyboards.
