 p.2 #4 · Canon DPP & MAC 10.6 Snow Leopard Incompatible | |
Part of the problem with DPP, from my understanding, is the way it is programmed to install. Any time DPP is installed or upgraded, it must be done so with super-user access. It is not possible to do it with user-level permissions, even if that user can sudo.
An installer for a non-system level application should not require login by the super-user in order to run.
Usually, when an application installs but the user executing the installation lacks sufficient privileges it will simply request an administrator's username and password. This happens even in Apple's own applications and security updates. This is not the case with DPP.
Most Mac users don't notice this problem because by default, the first user created on an OS X system is granted admin privileges, and this account is also usually the one that the machine's owner will use on a day-to-day basis. However, this is a less secure way of running your system. A correct setup involves creating two accounts: one super-user, one normal user. The normal user becomes the day-to-day account. If the normal user wishes to install an application, OS X will prompt for admin credentials in a pop-up window. This is a security feature. However, DPP does not work in this way--one must log into the super-user account and execute the binary from that account. This is incorrect installer behavior as even Apple's own applications do not require this.
I am not surprised there are compatibility issues with DPP on Snow Leopard. DPP for Mac is not a particularly well-coded application.
