MacBook Pro troubleshooting tips review 2017
Like any other PC, a Mac is also prone to encounter serious problems in its life. Numerous things could go wrong, from failure to start up or even that petrifying kernel panic screen. Today we will review some tips on how to trouble shoot your Mac and confidently fix it.
It is pretty clear that all problems that run into a Mac are worldwide across all versions of OS X. What more, if you are still covered by Apple’s warranty or Applecare, then the easiest way out is to walk into Apple Store and have them fix it for you for free. Then again, you if are not a time waster or your warranty has run out, then you can do the troubleshooting yourself.
BLUE OR GREY SCREEN ON STARTUP
Say you just turned on your Mac and you get a grey or blue screen that does not load OS X, this sure is a pretty cause for concern. This can happen due to various reasons and it is one of the most exasperating things that can happen to your Mac. What do you do?
Step One: Disconnect All Peripherals
Grey or blue screen during start up could be a result of incompatible hardware connected to the machine. It could either be the printer, external hard drive or even a USB hub. It is therefore advisable that you disconnect everything except not including the mouse and the Keyboard, and then restart your computer.
Should your Mac start this way, definitely it’s an issue with one of those peripherals. The next thing is to use trial and error so as to figure out which it could be. Connect them back one by one and restart your PC. If one of them causes the PC to hang on the Grey or Blue screen, then you have found your issue.
Once you have figured out the problematic peripheral, remove it and later you can a little research on how to fix it or how to update the device.
If devices are not the ones causing problems, an your Mac still won’t boot, then it’s time to dig a little deeper.
Step Two: Execute a Safe Boot
Performing a safe boot makes your Mac boot up with the least amount of drivers needed to make it work, and at the same time checks your hard disk in the process though it’s a very long process. To do this, start up your computer while pressing down the Shift key until the Apple logo passes. If your Mac starts up with the safe boot, go ahead and start the computer again and see if it boots up normally.
Step Three: Run Disk Utility
If you are still unable to boot up OS X normally, then it’s time to run Disk Utility and check out your hard drive: here below are the steps to follow to attain this;
- Boot up your computer while hard pressing the Command+R. This will boot you into a diagnostic mode.
- Select the Disk Utility Option.
- Select your hard drive, and click “Verify.” Wait for Disk Utility to finish running.
- If problems pop up, click “Repair Disk.”
- If nothing pops up, click “Repair Permissions” and wait for Disk Utility to scan your hard drive again.
- If Disk Utility finds and repairs some problems, go ahead and reboot.
In a many cases, running Disk Utility will seize problems with startup issues. Now and again a single file with the wrong permissions can cause the whole system to crush, or if something’s not in the right place it won’t boot. If this doesn’t work, you have a lot more problems to look into.
PERSISTENT BEACH BALL
This may appear as a spinning beach ball that refuses to go away. At times it can seem to be a small application problem and think it is easy to solve. But sometimes it is part of a much bigger mess. If you Mac keep constantly tossing up the spinning beach ball, it is high time to figure out the cause.
Step One: Check Activity Monitor
The spinning beach ball may occur if your Mac is overloaded. Normally, it may last a few seconds and go away; in this case you may choose to ignore it. Should it not go away, the only way to find out what is going on is to launch Activity Monitor and identify which program could be causing the problem.
- Press the Command+Option+Esc to force quit all programs that could be potentially causing the beach ball.
- Initiate Activity Monitor (Applications > Utilities).
- Now go about your daily usage. If the beach ball still pops up, switch over to Activity Monitor and see which app is taking up the biggest CPU.
You might find that it is a powerful software like Photoshop causing problems, then it is advisable that you add more RAM to your PC. This RAM will help in multi tasking issues and if the beach ball still pops when you are running a few programs at once, additional RAM will come to your aid.
Step Two: Reclaim Hard Drive Space
There are times when your hard disk may be fully packed hence no more available space. This is another potential cause of the spinning beach ball. For many PC users , this simply means cleaning up two folders ;namely; recycle bin and the downloads folder.
- Right-click the trash can icon and select “Empty Trash.” If you have a lot of stuff in there or you haven’t done this recently you might get enough space to save your file.
- Now head to your downloads folder (Users > Your Name > Downloads). Go through and delete any files you no longer need.
In most cases, performing the above two steps will be able to free up enough space to continue working. That said, you might still need to free up even more space. To make this process easy, I recommend the Disk Inventory X. With Disk Inventory X, you can have a look at your hard drive and find the largest space hogs fast so you can delete them and move on. It takes a little time.
If you have ever come across the black and grey kernel panic screen, you definitely know how unsupportive it can be. The Kernel panics are as a result of failure of multiple programs or the OS itself. Fortunately it is not a big issue as it may seem.
Here below are steps to take follow to try and clear the Kernel Panic Screen.
Step One: Reboot and See If It Happens Again
In nearly all cases, a kernel panic will force you to reboot you computer. Let this happen and if you are lucky you might be loaded right back into the OS X. resume working on your PC as normal. In many cases, the issue resolves itself, if not, then its time to figure out what’s going on.
Step Two: Update All Your Software
Software Update can often fix kernel panic problems because customarily, it’s a software issue. Click the Apple icon in the top left corner, and select “Software Update.” Let it look for and install new software to see if it fixes the problem.
In some cases should the kernel panic happen when you are starting up and you cannot load OS X, you will need to start up your PC in safe mode. Reboot the computer and long press the Shift key until the Apple Logo appears. After a short while you will load up safe mode. Here you can run Software Update the same way you usually do.
Step Three: Check Your Login Items
At times, there could be no software that needs updating and you can’t get your PC to start without a Kernel panic screen; this could mean the PC has problems with the programs you are automatically loading on start up.
If no software needs updating and you can’t get your computer to start without a kernel panic then it might be an issue with one of the programs you have loading up automatically on startup. That means its time to clear out your login items. While you’re still in safe mode you can remove any apps that start automatically:
- Open up your System Preferences (Applications > System Preferences).
- Select “Users and Groups” and select your user ID.
- Select the “Login Items” tab.
- Select each of the applications you have and click the minus sign to remove them from the list.
- Reboot and see if you can start without a kernel panic. If so, one of those apps is causing the problem. Try loading up each to see which one causes it again.
DISPLAY IS NOT WORKING OR IS DISTORTED
What do you do when out of nowhere the screen turns to a craze green and yellow and eventually your PC shuts down? Here are a few things you can do to troubleshoot and figure out exactly why your video card or display is acting out.
Step One: Reset the PRAM/VRAM and SMC
The reset procedure does not do the PC much good but it is one of the easiest things to do and it only takes a few minutes. Turn on your MAC and press down the Command+Option+P+R until the PC reboots. This will reset the PRAM/VRAM which is where the control panel is stored. Occasionally this will correct the display issues and should this happen, continue using your MAC as you did.
Another option is to reset the SMC (System Management Controller).The SMC controls everything in your PC. Once you reset the SMC most of your settings will be restored to factory defaults and your display issues will be solved.
Step Two: Boot into Safe Mode
The first step is to figure out what is going in with your graphics card or the display, then reboot into safe mode and see if the problem continues. Power on your PC and long press the Shift key until you pass the PC’s logo. If none of those work, it’s time to run the Apple Hardware test to see if it’s a hardware issue.
Step Three: Run Apple Hardware Test
The Apple hardware test is not a common test. Just the name suggests, this is a way to test for hardware crash on your computer. Up to now it has not been tested to be 100% perfect, but it will help you trouble shoot your issues.
- Reboot your Mac and hold down the “D” key until the Apple Hardware Test starts
- Select your language, and then select the “Basic test” option. Let it do its thing. If an error occurs, the Apple Hardware Test should tell you which piece of hardware is failing and you’ve found your problem. If not, select the “Perform Extended Testing” option. This might take an hour or two to complete.
While a hardware failure is never fun, expectantly the Apple Hardware test will actually show it so you can get the faulty hardware reinstated.
As with any computer troubleshooting, now and then you’ll need to go through all kinds of tests and experiments to figure out what is going on. If you’re lucky, the above tips will get your Mac in working order in no time.
