This is also because the apartheid government caved under not only international but more important domestic pressure as they were perfectly aware that there would be civil war and mass bloodshed if they had not given in to reforms and the end of apartheid. It's not clear what would have happened otherwise if, for instance, they had doubled down or intensified the apartheid system with even more extensive fascistic slave-labour in the 80s. As South Africa had an economic model that was descended from the settler-colonial plantation system, as seen, and utilized extensive unpaid (effectively slave) labor, it's not unimaginable that if they're pushed the system deeper then there would have been far more retaliatory bloodshed.
