MacBook Netflix Flicker Flashing in Full-screen

December 25, 2018 by Jack Zimmermann 46 Comments

I had an annoying problem on my 2015 MacBook Pro Mac OS when watching movies on Netflix using Safari. When in full-screen mode, the display would flash/flicker a couple of times a minute. Well, after digging around, I found a solution for it.

Why Does the screen keep flashing when watching Netflix?

Some MacBook Pro’s have dual graphics cards. Mac OS switches between them depending on what kind of work you are doing, and by switching cards it saves batteries. Unfortunately, the built-in Intel graphics cards are the reason for the flickering and flashing. So we need to turn on the high-performance graphics card when watching Netflix.

Mac OS How To Remove Purgeable on Hard Drive

April 20, 2017 by Jack Zimmermann 88 Comments

Can’t Remove Purgeable Disk Space

Note: If you have Mac OS High Sierra installed, you need this guide instead.

When trying to install Bootcamp on my MacBook Pro, I had to delete a lot of files to get enough space to be able to accommodate for a Bootcamp partition on the drive. But even after removing around 60 GB of storage, Mac OS Sierra could still not make a large enough partition for Windows. When checking with Disk Utility it showed that indeed I had enough space, but there was a part called Purgeable that was impossible to move. No tools from Apple are available to handle this, but here’s how I fixed it.

Clearing the Icon Services cache in Yosemite

"furbo.org · Clearing the Icon Services cache in Yosemite"

After installing or updating a system to Yosemite, I have seen blank (missing) icons on several Macs. I have also seen cases where the desktop doesn’t get updated after a change to the document icons in the application itself (which happens as developers update their apps to use the new icon guidelines.)

Saving this link for later. Looks like a good thing to know.

Apple seeds OS X Yosemite 10.10.2 beta with focus on Wi-Fi, Mail and VoiceOver

"Apple seeds OS X Yosemite 10.10.2 beta with focus on Wi-Fi, Mail and VoiceOver"

AppleInsider:

Apple on Wednesday issued a new beta build of its upcoming OS X 10.10.2 maintenance update, once again asking developers to focus on Wi-Fi, Mail and VoiceOver alongside general system compatibility testing.

I hope Apple manages to fix the Wi-Fi problem that I have with MacBook Airs since upgrading to Yosemite. Constantly dropped connection and the only solution to the problem? Turn off and then on the network again. The machines worked fine before upgrading and It’s very intermittent.
