Error message on my Mac
" D=01" is actually the most common error for MAC OS. It literally means "dsBusError" or let's just say "bus error". This is one sign of a memory associated error.
It may mean that you attempted to open a non existent or unreachable memory address. One of the most common reasons in this error  is, the Init / Extension or a control panel conflict. It may also be because of insufficient memory, for the application you tried to access. One best thing you could do is, try allocating more memory to this specific application.
You could also try and check for any Spyware or computer bugs, because this may also block your access to the application you want to reach. So it is sensible enough to try, Â a removal program like an Adware remover, to clean up any computer bugs.
Error message on my Mac
If the error appears very frequently, try checking if the error appears only in one particular program or with any other applications on your computer. Because if the error appears in any program you run then the problem is probably more serious. But if the error appears only in one particular program then there might be something wrong with the program’s files.
Maybe some of the files that run the application are corrupted. In this case, you need to reinstall the application to install a fresh copy of the program and restoring its entire settings back to default. First, make sure that only one program is affected by running each program on your computer. Once you find out which program it is, uninstall it from the machine and restart your computer.
After booting, run the application’s installer again to install it back. Another way that might help is to upgrade it to the latest version. Try checking the program’s official home page for any latest release, and then download and install it on your computer.
