How to update the SSD in a Mac Pro

Upgrading the SSD in the new Mac Pro is quite complex, not least because you have to reload the firmware for the T2 chip.

On 15 June 2020 Apple revealed that it was making a new new SSD kit for Mac Pro available that would enable customers to upgrade their internal storage from the original factory configuration. We’ve had a look at the process Mac Pro owners will need to go thought to perform the update. The steps are similar to installing RAM, except that users also need to delete the firmware on the T2 chip and reload it, which is a more complicated process and will require a second Mac.

The Mac Pro is the only Mac to have interchangeable SSDs, and up to two modules can be installed at a time. It is not difficult to install the modules themselves, the T8 screwdriver required is actually included with the SSD modules. Apple runs through this process on a support page. We recommend that you follow Apple’s 19 steps. The level of difficulty is about the same as replacing a memory module on an older Mac Pro (until you have to delete the firmware on the T2 chip, more on that below).

Create Bootable USB Drive With USBImager In Linux

Since the conception of Linux, so many of flavors in Linux operating systems are developed. Most of them can be downloaded from the internet. The downloaded Linux OS is usually a bootable ISO image. You can write it to either a CD or DVD or USB depending on the size of the ISO image. Nowadays, most of us use USB mass storage devices to write the bootable ISO images in Linux and Unix-like systems. There are many applications available to create bootable USB disks in Linux and each application has its own set of distinctive features. Today, we will discuss about one such tool called USBImager.

USBImager is a simple graphical application used to write the ISO images as well as compressed disk images to USB drives. Compared to its counterparts, USBImager is really really small. The size of this tiny application is around 170~ kb only. It doesn’t have any dependencies either. It makes synchronized writes, meaning, all data is on disk when the progress bar reaches 100%. It can verify writing by comparing the disk to images.

USBImager can read the RAW images, such as .img,.bin,.raw,.iso,.dd, etc., compressed images, such as .gz,.bz2,.xz,.zst etc, and archive files such zip (PKZIP and ZIP64). We can also create the backup of the entire USB drive. It is even possible to create compressed backups in raw and bzip2 formats. USBImager has an option to let the users to choose whether the backup should be compressed or not. USBImager is totally free and the source code is available under MIT license. It works under GNU/Linux, MacOS X and Windows platforms.

How To Easily Configure Flatpak Apps Permissions With Flatseal

As you may know, Flatpak is a software deployment tool that aims to ease software distribution and use in Linux. It is mainly developed to contain applications in a secure virtual sandbox allowing for using applications without the need of root privileges and without compromising on the systems security. Since the Flatpak apps are contained inside the sandbox environment, they have to request permissions to access other parts of the operating system, hardware devices (like bluetooth, network etc.) and sockets (like pulseaudio, ssh-auth, cups etc.). This guide teaches how we can easily configure flatpak apps permissions with Flatseal in Linux.

For those wondering, Flatseal is a simple graphical GTK application that allows the users to review and modify flatpak apps basic permissions. With the help of Flatseal, the users can easily control what access to grant individual flatpak applications. For example, the users can able to allow or deny network access to a specific flatpak application with a single mouse click! Another good advantage is you can easily reset the permissions to the default settings if something went wrong. This is an useful feature, especially for troubleshooting. If you are a heavy user of Flatpak apps, you might want to consider using Flatseal.
