General Guide for troubleshooting the most common Mac issues, system errors and to check for hardware malfunctions

With what it costs a Mac computer, it is also normal that Apple provides an excellent customer service and technicians ready for any repair of computers under warranty.
But you cannot bring a computer to assist any problem because even if it is no longer under warranty you can pay a lot of money for repairs that you could even do yourself.

Fix Mac OSX problems errors

Especially in the case of problems and errors more frequent side software , that is related to the operating system and programs in use, it is worth trying to repair the Mac independently following this general guide , which can not be complete, but that should represent a preliminary technical document absolutely to be kept.

1) First Step: The Backup: Before serious problems occur on the Mac that can affect the operation and before doing any operation on the system in trying to solve some error, it is important to have important data safe.

The Mac has an automatic backup function called Time Machine that should already be active or must be configured using an external hard drive to connect to the Mac to backup the data.
To learn more, there’s nothing better than Apple’s Guide to Time Machine .

2) Updates and antivirus check: Before anything else, you should make sure that everything on your computer is up-to-date: operating system, applications and device firmware.
To update your Mac, go to the Apple menu -> App Store and check the updates section to see if there are any applications to update.

If you are using other applications that do not come from the official App Store, check if there are new versions in the developer sites or using an app like AppFresh  that checks for itself if there are updates to download.

To be more comfortable then do an antivirus scan. Viruses also exist on Macs, especially in the form of adware that can cause many problems. It can therefore beDownload an antivirus for Mac or a program like Adware Medic specifically for adware.

3) Diagnosing the problem: hardware test: To understand the cause of the problem on a Mac you must first check whether it is a hardware malfunction , that is linked to the internal parts of the computer or software , linked to the system that for some reason may have lost the right configuration.

To check that the hardware is affixed, you can use the Apple Diagnostics or Apple Hardware Test .
To use this tool, turn off your Mac, disconnect all peripheral devices (except power supply, mouse, keyboard, and Ethernet connector.

Press the power button and hold down the D key until Apple Diagnostics starts.
Select a language, press enter and start the hardware test.  Once finished, you will get a report with some information on any problems detected.

To learn more about this tool, see the Apple guide .

4) Solving problems on the software side: If the hardware is ok, then there are errors on the OSX system that you can try to solve automatically using the internal Disk Utility tool (from Applications -> Utility )

In particular, in the SOS card it is possible to resolve the errors related to the authorizations and to the disk, putting it back especially after a blackout during use.

Authorization problems can often cause the most inexplicable errors, so it is good that there is a tool for checking and repairing them. If there are many permissions that need to be repaired, this may take some time.

5) Restore NVRAM / PRAM and SMC: The random-access parameter memory (PRAM) and the system management controller (SMC) can cause problems on a MAC then you can try to see if things improve by resetting the NVRAM or PRAM .

Turn the computer off, turn it on and, before the gray screen appears, press the Command – Option (Alt) – P – R keys together .

Hold down the keys until the computer is rebooted and release the keys (see guide ).

To restore the SMC ( drive ) depends on the type of computer you are using.

For a MacBook with a removable battery: turn off the computer, unplug the power adapter, remove the battery, press and hold the power button for five seconds.

Replace the battery, connect the power supply and turn on the computer. If your MacBook does not have a removable battery: turn off the computer, plug in the power supply and press on the keyboard, together, Shift-Ctrl-Option and the power button.

Release all the keys at the same time and then turn on the computer. On a Mac Pro, an Intel iMac, an Intel Mac mini: Turn off the computer, unplug the power cord, wait fifteen seconds, reconnect the cable, turn on the computer.

6) Remove the wrong software: If there is a specific application that seems to be the cause of the problem, the best solution is to uninstall it and see if the computer starts working better.
If it really is, you can try to reinstall it from scratch and maybe the initial problem will not show up again.

7) Reinstall OS X: If you cannot get over the problem, if something is not broken inside and if we have the time machine backed up, it is worth doing a reset / restore of the Mac and reinstall OSX .
Synthetically, three steps are required to reset the Mac:

Restart the Mac: When you see the gray screen, press and hold the Command + R keys.
When the option is available, select “Reinstall OS X “, follow the instructions on the screen and restart the computer.

If the problem persists even after a reinstall from scratch, then there is a hardware malfunction that probably will only fix a specialized technician , given the difficulty of repairing a Mac.

Before putting your hand to the wallet, however, it is worth taking a look, in addition to the Apple Diagnostic I mentioned above, to some online resources.

There are many sites where you can find tutorials and information on how to repair a Mac including the best are iFixit , Instructables and YouTube .
