Today I received an email from my favorite online backup service Backblaze one that advised me that my online backup is currently no longer running. Mojave's new security measures require user intervention as the Backblaze program does not have the necessary permission to access the hard drive. The instructions in English that came with the mail may be a bit cryptic to some people. For this reason, I would like to briefly describe the necessary steps in more detail with screenshots.
Chapter in this post:
Instructions in condensed form
If the detailed instructions with screenshots are too extensive for you, I have a compilation with short bullet points that describe the procedure:
- Latest BackblazeDownload and install version
- Open System Settings -> Security
- Select the "Privacy" tab and "Full access to hard drive".
- Click on the lock at the bottom left and unlock it
- Click the plus symbol (+) in the window
- Select Backblaze from the program list
Step-by-step instructions with screenshots
Update the Backblaze Client
First we go to the download or updates page of Backblaze and download the latest version for the Mac: https://secure.backblaze.com/update.htm
This is actually necessary because the Backblaze client doesn't seem to update itself. At first I thought I must have the latest version installed, but if you click the Backblaze icon (that flame) at the top of the menu bar and choose About, a window pops up with the version number that's currently installed - and here I was a few version jumps behind the currently available version:
Once you have loaded and started the Backblaze installer, you will be asked whether you really want to start the program from the Internet. Yes, we would! Then a few more steps follow and you have to enter your password so that the old client can be replaced by the new one. Once the installation is finished, there are brief instructions on how to give Backblaze the necessary access rights to the hard drive. I explain this in the following section.
Grant Backblaze access to the hard drive
Under macOS Mojave, programs are no longer allowed to access any part of the hard drive without the user's consent in order to protect the user's privacy. With a backup program, however, this restriction is a bit impractical, because every file must be able to read in order to save it. Accordingly, we are now giving Backblaze the appropriate rights.
Now in the list of programs with “Full access to disk” you should see Backblaze, like mine above. Please excuse the “High Sierra” background. I hadn't changed the desktop background when I took the screenshot. But my system is already running on Mojave. :D
You can see whether Backblaze is running again by clicking on the Backblaze icon in the menu bar and then selecting “Backblaze Preferences”. There should be a green tick in the top left corner of the window.
