How to fix problems in Mac OS X?
Mac OS X is not perfect. Although it may be classified as more stable than Windows, it’s a good idea to know how to fix it when it doesn’t start.
It rarely happens and is more of a hardware issue than a software one according to Norske Anmeldelser. However, a MacBook, an iMac, or a Mac Pro are not infallible systems, and Mac OS X is not a perfect operating system. It may not start, get stuck in an error message, or become incredibly slow.
In such situations, the so-called troubleshooting steps must be initiated. You have to take several steps in the hope of fixing the problem. If none of them work for you, you need to know a quick way to reinstall your operating system.
Where do we start?
It all starts with commands, key combinations that you press or hold as soon as you turn on your Mac. Parallels can help you much easier with this problem and it is the safest way. These shortcuts call for tools built into OS X in a very similar way to what you can do on Windows. If it doesn’t work at first, chances are you missed the exact moment you need to press them. Shut down the computer and try again.
Whether you have an OS X and Windows system installed in Bootcamp or simply want to boot the system from a USB stick or CD / DVD, you need to enter Startup Manager. Similar to the image above, it can be dialed by holding down the Option or Alt key immediately after the system is turned on. You can also select a wireless network from here if you want to rewrite the recovery area on a Mac.
Hardware diagnostics and tests
If you think there is a more serious problem with your systems, such as a faulty hard disk or unstable RAM, there is a utility called Apple Diagnostics that you can use to start the system. On Macs older than June 2013, it is called the Apple Hardware Test or AHT, but the functionality is identical.
Safe Boot or Safe Mode
If you have been using Safe Mode on Windows for a few years, it is good to know that there is something similar on OS X, only that on the operating system developed by Apple it is called Safe Boot. It can be dialed by pressing the Shift key when the computer is turned on. When a loading bar like the one above appears, you can take your finger off the Shift.
Causes that a Mac does not activate and solutions
Any computer that borrows is a complex system of components, cables, and circuits that make it work. Any minor change or defect in one of them may cause it to cease. This is why the cause of a Mac startup is not always the same, and it may be due to something uninspected, but here are some of the most common cases to find out what happens to your computer before you go to fix it.
Other common issues on MacBook, iMac, and Mac
Something that affects all Apple computers is the graphics card, which is responsible for processing all the information related to the images you see on the screen. Needless to say, a failure in this can be crucial to displaying the screen with strange graphics, to be turned off or even the whole computer is not able to start. This malfunction is one of the most tiring and always requires the supervision of an expert, so we recommend that you go for technical assistance.
