I have an old Macbook CoreDuo. It's maxed out at 2GB RAM and 10.6.8. Currently, it's being used by my 6 year old 1st grader and for the most part, it's OK. The problem is when he surfs educational websites which still relies on Flash technology. I have the latest versions of Safari, Chrome and Firefox installed and they all choke/don't work on several websites. None have been able to work on all of the sites the teacher have recommended. Has anyone had better results for an alternative browser? Needs to work on Flash sites, and preferably have parental lockouts (which I had to disable to use Safari). Thanks!
