Then we ran the good ol' Blackmagic Speed Test and we were quite shocked at the results. On the old Retina MacBook Pro from back in mid 2012, we were happy with over 400 MB/s read/write. But then there were a few naughty words of amazement in the FCP.co office when we ran the test on the new MacBook Pro. I have a MacBook Pro 8,2 early 2011 running Mavericks.

What’s more frustrating than a frozen computer? One that stops working altogether.
When a MacBook Pro freezes, you can hit Command + Shift + Option + Escape to kill a frozen app or do a hard restart by holding the power button, but if those freezes keep happening, there’s a bigger underlying issue. Some problems warrant a trip to an Apple Genius Bar, but there are actually quite a few simple things you can try yourself to fix a frozen MacBook. From changes in computer habits to updating your macOS, here are five solutions to consider when your MacBook Pro keeps freezing. Close Applications Often, MacBook freezes aren’t caused by certain applications, but from running too many programs at once. A computer’s RAM (Random Access Memory) is the working memory, and when that fills up, it needs to reach into the hard drive space to operate.
Besides making the computer slow, filling up the RAM by multitasking can cause MacBook Pro freezes. Once you’ve re-started your Mac from that freeze, open Activity Monitor (do a quick Spotlight Search to find it). Click on the Memory tab and take a look at the Memory Pressure graph on the bottom. Green means you have enough RAM left to open additional programs, but once the graph starts turning yellow, you should close unnecessary programs or take a look at what applications are hogging your memory by looking at the programs listed above that graph. When you see red on that graph, your MacBook is using hard drive space, not RAM, to run, and a random or permanent freeze is likely coming if you don’t close out some applications., especially with an older MacBook Pro (prior to 2013 models), would help, but that can get expensive and isn’t always necessary. Try identifying programs that are using the most memory and swapping them for an alternative like replacing Firefox with Safari. Avoid using multiple programs at once when possible, and limit the number of tabs you open when browsing the Internet.

To keep your MacBook Pro running at its peak, you should keep your disk drive no more than 85 percent full (source: ). If your disk is full, it’s time to delete unnecessary files and apps you don’t use anymore, or use to store files that you don’t access very often. Take a look at where your disk space is going with the color-coded graph to know where to start freeing up space. In my case, photos are usually the culprit, so I now store them on an external hard drive. You can also use a third-party app like to find and delete unnecessary files.
