What are the potential dangers to be wary of when changing the root drives read/write permission? Specifically, granting "everyone" read/write access?
E.g. will I be opening up my computer to potential malware attacks/viruses and such? Will I be compromising my system integrity? Will it be easier for me to catastrophically damage or erase my entire system? Am I just being paranoid?
Use case: I've recently installed Avid's Media Composer | First and while I can use external drives (and likely a partition of my internal SSD), as is I am unable to use the internal drive for writing media files (like renders and when ingesting files.) Of note, I can "link" to files just fine, but importing to Avid codecs requires a drive the app can write to. When I launch the application without any external drives mounted, I get this warning:
Per the Avid Knowledge Base a solution involves changing the write protection for the drive's root folder so as to allow Media Composer | First to create and populate its "Avid Media Files" folder:
If you do need to use the system drive as a media drive, take the following steps to change permissions
- Click on your system (Macintosh HD in most cases) drive to highlight
- From the File menu select Get Info (cmd+I)
- Click the lock icon in the bottom right to make changes
- Click on the “Read only” text in the Privilege column next to Everyone and set the privilege to “Read & Write” You should now be able to see the system drive as a valid media drive.
Note: If you repair permissions on the system drive, they will reset and you will have to repeat this procedure.
For whatever it is worth, I am the only user of this particular computer and I do have it backed up regularly with Time Machine. Partly I am asking for my own understanding, but also, if I were trying to set up a family member with this free editing software and they also let their kids use the laptop, it seems like granting everyone read/write might be make for more of a potential problem or accidents? Am I being overly cautious, or perhaps, by making the change, eagerly risky?
