Even though the MacBook Pro is weigh to be one of the good professional laptop in terms of build up calibre and execution , it ’s not invincible . There are known MacBook hardware issues that Apple acknowledges and happily provide repair for . However , some effect are not that widespread and we have to figure out the solution ourselves . We have a MacBook Pro that started show horizontal line on the blind . In this article , I will walk you through the process of how we triangulated the job and fix or got rid of horizontal lines on our MacBook Pro . Let ’s begin .
What Causes Horizontal Lines on MacBook Pro
There could be a ironware issuing , a software system error , or a combining of both that may be causing horizontal lines to appear on your MacBook Pro video display . Our 13 - inch MacBook Pro 2016 framework start out showing horizontal line due to a hardware effect .

2. Check for an Existing Service Program for Your MacBook
MacBook Pro that came out in the last few year has had some problem that have pushed Apple to eject worldwide table service programs that fix those issues free of cost . One of the most notable example is the Butterfly Switch keyboard that hold open failing and Apple eventually issued a free refilling for the keyboard .
In our case , the MacBook Pro 2016 shows horizontal lines on the show . Fortunately , there is adisplay - related divine service program offer by Applefor our MacBook Pro model .

alas , our MacBook Pro did n’t specify for the Service Program and we were quote $ 600 for a complete display renewal .

After hours of researching , I establish that our MacBook Pro only starts showing the horizontal lines on the screen when the auto is under stress and the processor is doing large lifting generating oestrus . As the temperature heighten , the lines get spoilt . One speedy direction to mitigate that problem is to use a bang-up app that ramps up the fan to help cool down the MacBook Pro .

So , these are all the steps you’re able to take to get your MacBook Pro fixed . I adjudicate to apply the MacBook Pro in the Clamshell modality indefinitely as it never left the office desk anyway and it ’s cheaper to buy an extraneous monitor and wireless keyboard , and a Mouse than to supercede the display from Apple . What ’s your take ? Would you rather get your MacBook display serviced or employ the laptop computer in Clamshell mode ? countenance me have intercourse on Twitter .
