Technology is continually progressing and computing updates are constantly released to refine computer features for a smooth computing experience. There have been many creative names given to the operating systems of android smartphones while Windows OS remained in the backseat and did its thing, there has been little talk regarding Apple iOS much more that of an update.

And over the years, the lack of updates and new releases from the Apple’s Macbook line is a cause of concern for Macbook users who are wondering when they can upgrade their computers to match their growing computing needs. The Apple computer line is also not immune from various iOS issues. Let’s take the macOS Sierra, for instance, which made its debut last year and a couple of issues you immediately face once using this operating system.

Before installing macOS Sierra, uninstall or disable any antivirus software on your Mac, as that may be causing issues.

Press the power button on your machine while holding down the Shift key on your keyboard. Boot your Mac into Safe mode, then try installing macOS Sierra again. It might also be worth switching from a Wi-Fi connection to a wired connection before you download and install.

macOS Sierra problems: macOS Sierra won’t start

If you’ve installed macOS Sierra, but your Mac won’t start, then restart your Mac and hold down Command, Option, P and R, which will reset the NVRAM (non-volatile RAM).

Hold the keys down until the computer restarts and you hear the startup chime for the second time. Release the keys after you hear the second startup chime. The PRAM will be reset as well.

macOS Sierra problems: Mac runs slowly after macOS Sierra upgrade

If your Mac is running noticeably slower after upgrading, there are a number of things you can try to speed up macOS Sierra.

First of all, try restarting your Mac to see if that helps. If it doesn’t, force-quit any apps that appear to be taking up a lot of RAM. You can identify these by using Activity Monitor (in /Applications/Utilities) to establish what apps and processes are using up the most CPU or RAM. Its CPU tab lists active processes, with a real-time view of what’s going on.


Now, regardless of your iOS version or whether you are simply just having a hard time to turn on your Mac computer, do you know what to do or will you wait for a miracle to happen and wait for it to turn on by itself? Here is a rundown of what you need to do to get your computer back up without spending a lot of money in getting it checked and fixed by a professional.

How to fix a Mac that won’t start up: Check your Mac turns on

First, let’s check that the problem is that your Mac won’t start up, and not that it won’t turn on – those might sound like the same thing, but there’s actually a big difference.

Press the Power button on your Mac. If you don’t hear a start-up chime, you don’t hear any fan or drive noise, and there are no images, video or visuals of any sort on your display, then your Mac isn’t turning on at all. You’re not even getting to the point where it refuses to start up.

A Mac that doesn’t turn on calls for a different approach to one that doesn’t start up. If your computer doesn’t turn on then you need to do the following:

Check your power connection: Don’t be the cliche, check that the power is on and the Mac is plugged in correctly. Or if it’s a laptop be sure that the battery isn’t dead – and if it needs charging give it a while to attempt to charge before concluding that it isn’t going to work.

Try a different power cable or adaptor: It may be that the fault resides with the power cable. If you have a friend with a Mac power cable that fits your machine try it to see if that solves the problem. If it does it could be a simple fix that involves finding a secondhand power cable on eBay (we’d advise against buying third-party power cables that aren’t made by Apple as they are much more likely to be faulty and possibly dangerous).

If you recently had a power cut that could be responsible: Your power adaptor could have been damaged in a power surge and you may need a new one.

It’s possible that the cable was lose and pulling it out and plugging it in again will solve the problem, but we doubt it will be that easy.


The world of Apple is not for everybody. It has so many idiosyncrasies only loyal Apple computer users can relate to. Using it requires a different knowledge and skill set considering that Apple computers are built differently than the rest of PCs most of us are familiar with.

Even though Apple rarely updates their computer line and operating system, what they have now in place does the job and works for most of their users. And if in case its use is no longer a positive experience for the user, they have the choice of waiting for when a new model is eventually released or switch to a Windows PC that you can find all over the market as a replacement.
