while additions had been relatively limited, so had fixes to some of the underlying oddities of the system architecture. for instance, to support a limited form of multitasking, the original mac os supported small co-resident programs known as desk accessories which had to be installed into the system using special tools. if the system were able to support multiple tasks, this one-off solution would no longer be needed — desk accessories could simply be small programs, placed anywhere. yet, as multifinder was still optional, such a step had not been taken. numerous examples of this sort of problem could be found throughout the system.
