It also brings fun new ways to create super expressive messages. Moreover, it helps you rediscover your best photos, work more seamlessly between devices, and free up valuable storage space. slow speed of Ubuntu 12.The macOS Sierra released in the market with latest technology and features.Here are some links to get started on tuning and learning: Add memory to the guest OS when the applications you run there start to swap out to disk. Allocating too much memory on ubuntu will make the OS X starved for RAM to cache the guest OS. Since free memory is a waste on both OS X and Ubuntu - you will want to allocate all the RAM to OS X so it can cache all the file input and output for both OS X and virtual box. Over time, you can shift to logging things more slowly with vm_stat 60 / vmstat 60 or even time stamp the usage. Also pay attention to the memory pressure on OS X. To initially monitor things, I would open terminal on both the host and guest and run something like vm_stat 5 - pay attention initially to only two numbers - the free and the swap out. Second - both Ubuntu and OS X use virtual memory so that you could allocate 1 GB of Ram to the guest OS and it will use a swap file to make more memory as needed. Virtual box makes a file or files to act as the storage for Ubuntu but OS X is handling all the actual reads/writes. So - you have 16 GB of RAM and one OS X running the hardware with Ubuntu running in Virtual Box. In the red, you will be swapping and slowing down the response times. If you are in the orange, that's ok, but you might want to try changing the reservations (less RAM to ubuntu guest or quit apps on either OS that take most active memory). On the Mac - open Activity monitor and watch the memory pressure. My best practice is to think about how to get the best use of your RAM and not make configuration decisions that lock down memory and instead monitor for problems on each OS and then make small adjustments.
